AXIS 211M - Video Stream  
Video Stream  
The AXIS 211M provides several different image and video stream formats. The type to use depends on your  
requirements and on the properties of your network.  
The Live View page in the AXIS 211M provides access to MPEG-4 and Motion JPEG video streams, as well as  
single JPEG images. Other applications and clients can also access these video streams/images directly, without  
going via the Live View page.  
How to stream MPEG-4  
This video compression standard makes good use of bandwidth, and can provide DVD-quality video streams at  
less than 1 Mbit/s. Note that the image settings of the MPEG-4 stream are the same for all clients.  
Deciding on the combination of protocols and methods to use depends on your viewing requirements, and on  
the properties of your network. The available options in AMC are:  
Unicast RTP  
This method (RTP over UDP) should be your first con-  
sideration for live video , especially when it is impor-  
tant to always have an up-to-date video stream, even  
if some images are dropped.  
Unicasting is used for video-on-demand  
broadcasting, so that there is no video traf-  
fic on the network until a client connects  
and requests the stream.  
Note: There is a maximum of 20 simulta-  
neous viewers.  
RTP over RTSP  
This unicast method (RTP tunneled over RTSP) is use-  
ful as it is relatively simple to configure firewalls to  
allow RTSP traffic.  
RTP over RTSP over HTTP  
Multicast RTP  
This unicast method can be used to traverse firewalls.  
Firewalls are commonly configured to allow the HTTP  
protocol, thus allowing RTP to be tunneled.  
This method (RTP over UDP) should be your first con-  
sideration for live video, especially when it is impor-  
Multicasting provides the most efficient  
usage of bandwidth, especially when there  
tant to always have an up-to-date video stream, even are large numbers of clients viewing simul-  
if some images are dropped.  
taneously. Note however, that a multicast  
broadcast cannot pass a network router  
unless the router is configured to allow this.  
It is thus not possible to multicast over, e.g.  
the Internet.  
AMC will negotiate with the camera to determine exactly which transport protocol to use in the order listed  
above. This order can be changed and the options disabled, to suit any specific requirements.  
Important!  
MPEG-4 is licensed technology. The AXIS 211M includes one viewing client license. Installing additional  
unlicensed copies of the viewing client is prohibited. To purchase additional licenses, contact your Axis  
reseller.

AXIS 211M - Video Stream  
MPEG-4 clients  
AXIS Media Control (AMC)  
The recommended method of accessing live video (MPEG-4 and Motion  
JPEG) from the AXIS 211M is to use the AXIS Media Control (AMC) in  
Microsoft Internet Explorer in Windows.  
The AMC control panel can be used to configure various video and audio  
settings. Please see the readme file included in the tool for more  
information.  
The AMC control panel is automatically installed on first use, after which  
it can be configured. Open the AMC Control Panel from:  
• Windows Control Panel (from the Start menu)  
• Alternatively, right-click the video image in Internet Explorer and  
click Settings in the menu.  
For more information on the AMC settings, please refer to the AXIS  
Media Control User’s Manual available from the Axis Web site at  
http://www.axis.com  
QuickTime™ & Real Player™  
To access the video stream from, e.g. QuickTime™ or Real Player™ the following paths can be used:  
• rtsp://<ip>/mpeg4/media.amp  
• rtsp://<ip>/mpeg4/media.3gp  
Notes: • The AXIS 211M supports QuickTime 6.5.1 (or later) and Real Player 10.5 (or later)  
• QuickTime adds latency to the video and audio stream (up to 3 seconds)  
• It may be possible to use other players to view the MPEG-4 stream using the paths above, although this is not guaranteed by  
Axis Communications AB  
Motion JPEG  
This format uses standard JPEG still images for the video stream. These images are then displayed and updated  
at a rate sufficient to create a stream that shows constantly updated motion.  
The Motion JPEG stream uses considerable amounts of bandwidth, but provides excellent image quality and  
access to each and every individual image contained in the stream. The recommended method of accessing  
Motion JPEG live video from the AXIS 211M is to use the AXIS Media Control (AMC) in Microsoft Internet  
Explorer in Windows. Note also that multiple clients accessing Motion JPEG streams can use different image  
settings.  
Alternative methods of accessing the video stream  
Video/images from the AXIS 211M can also be accessed in the following ways:  
• Motion JPEG server push (if supported by the client, e.g. Firefox). This option maintains an open HTTP con-  
nection to the browser and sends data as and when required, for as long as required. See HTML Examples, on  
page 27.  
• Still JPEG images in a browser. Enter, e.g. the path: http://<ip>/axis-cgi/jpg/image.cgi?resolution=320x240  
• Windows Media Player. This requires AMC and the MPEG-4 viewing client to be installed. The paths that can

Video and Image settings  
The following descriptions show examples of some of the  
features available in the AXIS 211M. For details of each  
setting, please refer to the online help available from the  
setup tools. Click  
to access the online help  
Image Appearance  
Use these settings to change the image as required. The  
image can be rotated, the image resolution and  
compression can be adjusted, and the white balance can  
be changed.  
Resolution includes wide screen 16:9, partial which  
stands for partial scan where an image is taken from the  
center region of the sensor for optimal frame rate in  
Motion JPEG/MPEG-4 and full speed which is a partial  
scan that has been scaled down to give full frame rate in Motion JPEG.  
The configuration of the video image will affect the camera’s overall performance, depending on how it is used  
and on the available bandwidth. Setting higher resolution and lower compression improves video image quality,  
but increases the amount of bandwidth used.  
Please see the online help for further information on these settings.  
Text Overlay Settings  
Use these settings to include text and date  
and time overlays.  
Text, date and  
time overlays  
These overlays are included on one line, at  
the top or bottom of the video image.

Overlay image requirements  
Image Formats  
Image Size  
•
•
Windows 24-bit BMP (full color)  
Windows 4-bit BMP (16 colors)  
The height and width of the overlay image in  
pixels must be exactly divisible by 4.  
The height and width of the overlay image in  
pixels must be exactly divisible by 16.  
There are a number of limitations when using overlay images, such as the size and positioning of images. Please  
refer to the online help for more information.  
Configurable areas as privacy mask are configurable areas of solid color that can be used to block out certain  
parts of the video image.  
Note: Make sure to set privacy masks while camera is set for full resolution to ensure full coverage of sensitive area.  
Advanced - Camera Settings  
This page contains settings for fine-tuning the video image. These include the color level, brightness, sharpness  
and exposure control. DC-Iris should always be enabled, except when focusing, or when using a non-DC-Iris  
lens.  
Please see the online help for further information on these settings.  
Low Light Behavior  
Exposure priority - These settings define the balance between possible motion blur, noise and frame rate.  
Prioritize Image Quality to lower noise may reduce frame rate while increasing exposure time and thereby  
motion blur. A prioritized frame rate limits the exposure time in order to allow for full frame rate. This may raise  
the gain factor, creating possible noise or darker exposure.

AXIS 211M - Video and Image settings  
Advanced - MPEG-4 Settings  
GOV Settings  
The GOV structure describes the composition of the MPEG-4 video stream. Setting the GOV-length to a high  
value saves considerably on bandwidth. The Cyclic refresh parameter gives a smoother bit rate and can be  
useful if bandwidth is limited.  
Note: Cyclic refresh should not be enabled if Event handling is enabled and the file format is set to MPEG-4 in Upload images/video (see  
Setup > Event configuration > Event settings).  
Bit Rate Control  
Limiting the maximum bit rate is a good way of controlling the bandwidth used by the MPEG-4 video stream.  
Leaving the maximum bit rate as unlimited will provide consistently good image quality, but at the expense of  
increased bandwidth usage whenever there is more activity in the image. Limiting the bit rate to a defined value  
will prevent excessive bandwidth usage, but images will be lost when the limit is exceeded.  
Note that a maximum bit rate can be used for both variable and constant bit rates.  
The bit rate type can be set as Variable Bit Rate (VBR) or Constant Bit Rate (CBR). VBR will adjust the bit rate  
according to the images' complexity, thus using a lot of bandwidth for a lot of activity in the image and less for  
lower activity in the monitored area.  
CBR allows you to set a fixed Target bit rate that will consume a predictable amount of bandwidth, and which  
will not change whatever happens in the image.  
As the bit rate would usually need to increase for increased image activity, but in this case cannot, the frame  
rate and image quality will be affected negatively. To go some of the way towards compensating for this, it is  
possible to prioritize either the frame rate or the image quality whenever the bit rate would normally need to be  
increased. Not setting a priority means the frame rate and image quality will be affected approximately equally.

AXIS 211M - Audio Settings  
Audio Settings  
The AXIS 211M can transmit audio to other clients using a connected external microphone or the internal  
microphone and can play audio received from other clients via connected speakers. This section describes how  
to configure the basic audio settings for the AXIS 211M, e.g. set the communication mode and adjust the sound  
levels in the microphone and speakers connected to the camera.  
Note: The speakers connected to the audio output must have a built-in amplifier, e.g.  
Client PC  
PC speakers.  
Enable Audio  
Check this box to enable audio in the AXIS 211M.  
TCP/IP Network  
Audio Channels - Audio mode  
Full duplex mode is simultaneous two-way audio where you can  
transmit and receive audio at the same time.  
Example of a network  
Half duplex mode transmits and receives audio in both directions,  
but only in one direction at a time. This means that you must select  
when to receive or transmit audio with the push-to-talk button. To  
using AXIS 211M cameras to transmit  
audio and video across the network.  
speak, press and hold the button (check that the microphone is not muted). When finished speaking, release the  
button and you will receive audio from the other end of the connection.  
Note that the push-to-talk button is configured from AMC. It is also possible to configure the push-to-talk  
button so that it toggles between speaking and listening modes.  
When selecting Simplex - Network Camera speaker only mode, the speaker connected to the camera will play  
audio, but no audio will be transmitted from the camera to other web clients. This could be used to e.g. provide  
spoken instructions to a person seen in the camera. This mode requires you to use the push-to-talk button.  
Simplex - Network Camera microphone only mode transmits audio only from the AXIS 211M to web clients. It  
will not receive audio from any other web clients. This can be used in remote monitoring, web attractions etc.,  
to provide live audio, as well as video, of a monitored situation.  
When using half duplex, the Send the sound from the active client to all other clients option transmits the  
audio signal from the client that is talking to all the other clients.  
Audio Input  
Audio from a connected microphone or a line source can be connected to the Audio in connector of the AXIS  
211M. The audio source must be set to Microphone or Line depending on the connected device.  
Note: To prevent unauthorized listening, the internal microphone can be disabled by inserting a plug in the Audio in connector.  
The Enable microphone power option provides DC power for an external microphone. If using a small electret  
microphone such as a clip-on mic or a PC microphone, this option needs to be enabled.  
Note: To use a high impedance dynamic microphone, DC power should not be enabled. DC power will not harm the microphone, but if you are  
uncertain, try switching it off and on. The default value is DC power enabled. To use a professional microphone requiring 48V phantom  
power, you need an external power supply and must use a balanced-unbalanced converter (audio transformer) in between.  
Set Input sensitivity to High or Low depending on the sound level in the monitored are. For example, if the  
AXIS 211M is installed in a noisy environment set the sensitivity to Low. When using an external microphone  
set the Input sensitivity to High if you are using an ordinary, unamplified microphone. Set the sensitivity to  
Low if the connected microphone has a built-in line amplifier.  
Enable microphone power with electret microphones that have no battery. Do not use this setting with a  
dynamic or battery powered microphone.  
Select the desired audio Encoding format G711, G726 or AAC.

AXIS 211M - Audio Settings  
Depending on the selected encoding, set the desired Bit rate (audio quality). The settings depend on the  
available bandwidth and the required audio quality, i.e. a high bit rate setting requires more bandwidth.  
The AXIS 211M can be set to trigger an event if the incoming sound level rises above, falls below or passes the  
set value. The Alarm level is set between 0-100%.  
Audio Output  
If the sound from the speaker is too low or high, adjust the output gain for the active speaker attached to the  
AXIS 211M. When satisfied with the settings, click Save, or click Reset to revert to the previously saved  
settings.  
Advanced Audio  
Advanced audio settings can improve audio quality by speech filtering, echo cancellation or setting the noise  
canceller threshold value or attenuation..  
When enabled the speech filter reduces noise by filtering out all the frequencies below 100HZ and above 3500  
Hz. This improves the sound quality if a person is close to the microphone when talking and will reduce  
background noises.  
Enable echo cancellation to reduce acoustic echoing that can be caused by audio coming from a speaker being  
captured by a microphone.  
Noise canceling is a way of reducing the background noise if the microphone, for example, is set up in a noisy  
environment and you are only interested in hearing a person who is talking close to the microphone. The noise  
canceller attenuation produces maximum noise reduction when set to 18dB of attenuation. Optimize the sound  
quality by listening to the sound and adjusting the attenuation level as required.

AXIS 211M - Live View Config  
Default Viewer  
When using Microsoft Internet Explorer (IE) for Windows, select your preferred method of viewing moving  
images. The options are:  
• AMC(ActiveX)- This is the best choice for fast image updating in Internet Explorer, but might not be  
possible on computers that have restriction on the installation of additional software.  
• QuickTime - For use with MPEG-4 only, select this to use the QuickTime plug-in for Microsoft Internet  
Explorer.  
• Java applet - This alternative uses a Java applet to update the images in the browser.  
• Still Image - Displays still images only. Hit the Refresh button in your browser to view a new image.  
When using any other browser than Internet Explorer for Windows, select the appropriate method from the  
drop-down list for viewing images. The available options are similar to Internet Explorer except for Server  
Push. With this method, the camera maintains and controls an open HTTP connection to the browser and sends  
data as and when required for as long as required. Please see the online help  
for more information.  
HTML Examples  
You can add live video from the camera to your own web site. The camera can transmit a Motion JPEG or  
unicast MPEG-4 stream to up to 20 simultaneous connections, although an administrator can restrict this to  
fewer. If multicast MPEG-4 is used, the video stream will be available to an unlimited number of viewers  
connected to the parts of the network where multicast is enabled. Please note that a separate MPEG-4 license is  
required for each viewer.  
Enter the Video Format, Image Type, Image size and other settings to suit your Web page and click Update.  
The camera then generates the required source code for your configuration. Copy this code and paste it into  
your own Web page code.  
External Video  
The camera can also display video images from other Axis network cameras and video servers, directly on the  
Live View page. These are known as External Video sources. These external video sources are available from the  
drop-down list on the Live View page.  
Click the Add button to open the External Video Source Setup dialog, which is used to make all the necessary  
settings. Enter the IP address or host name of the external video source you wish to add. Depending on the

AXIS 211M - Event Configuration  
Event Configuration  
An event in the camera is when an Event Type is activated and causes certain actions to be performed. The  
event type is the set of parameters (or conditions) that specifies how and when which actions will be performed.  
A common event type is when the camera uploads images when an alarm occurs. Many event types use an  
Event Server, to e.g. upload images to.  
This section describes how to set up event servers and event types, i.e. how to configure the camera to perform  
certain actions when events (e.g. alarms) occur.  
Definitions  
Event type  
A set of parameters describing how and when the camera will perform certain actions  
The circumstances that start an event.  
E.g. on a signal from an external device, such as a door  
switch or a motion sensor.

approximately 10 seconds).  
Configuring Event Types  
An Event Type describes how and when the camera will  
perform certain actions.  
Example: If somebody passes in front of the camera and an event that uses  
motion detection has been configured to act on this, the camera can, e.g.  
record and save images to an FTP server, and/or send a notification e-mail to  
a pre-configured e-mail address with a pre-configured message. Images can  
be sent as e-mail attachments.

AXIS 211M - Event Configuration  
Triggered Event  
A Triggered event can be activated by:  
• Input port - a switch (e.g. a push button) connected to the camera  
• Manual trigger - a manually activated action, e.g. from an action button in the web interface  
• Detected movement in a configured motion detection window  
• Audio alarm  
• on restart (reboot) after, e.g. power loss  
How to set up a triggered event  
This example describes how to set the camera to upload images when, e.g the main door is opened:  
1. Click Add triggered on the Event types page.  
2. Enter a descriptive name for the event, e.g. Main door open.  
3. Set the priority - High, Normal or Low (see the online help).  
4. Set the Respond to Trigger... parameters for when the event will be active, e.g. only after office hours.  
5. Select the trigger alternative from the Triggered by... drop-down list, e.g. select Input port, for the  
sensor connected to the door.  
6. Set the When Triggered... parameters, i.e. define what the camera will do if the main door is opened  
e.g. upload images to an FTP server or send an e-mail.  
7. Click OK to save the Event in the Event Types list.  
Please use the online help  
for descriptions of each available option. Image file names can be formatted  
according to specific requirements, such as time/date or type of triggered event. See File Naming & Date/Time  
Formats under Event Configuration.  
Note: Up to 10 event types can be configured in the camera, and up to 3 of these can be configured to upload images.  
Pre-trigger and Post-trigger buffers  
This function is very useful when checking to see what happened immediately before and/or after a trigger, e.g.  
up to 30 seconds before and/or after a door was opened. Check the Upload images checkbox under Event Types  
> Add Triggered... > Triggered by... to expand the web page with the available options. All uploaded images  
are JPEG images.  
Include pre-trigger buffer - images stored internally in the camera from the time immediately preceding the  
trigger. Check the box to enable the pre-trigger buffer, enter the desired length of time and specify the required  
image frequency.  
Include post-trigger buffer - contains images from the time immediately after the trigger. Configure as for  
pre-trigger.  
Notes: •Pre-trigger and Post-trigger buffers will be lost if the connection to the event server fails.  
•The maximum length of the pre-/post-buffer depends on the video image size and selected frame rate.  
•If the pre- or post-buffer is too large for the camera’s internal memory, the frame rate will be reduced and individual images may be  
missing. If this occurs, an entry will be created in the unit's log file.  
Continue image upload (unbuffered) - enables the upload of video images for a fixed length of time. Specify  
the length of time for the uploaded recording, in seconds, minutes or hours, or for as long as the trigger is  
active. Finally, set the desired image frequency to the maximum (the maximum available) or to a specified frame  
rate. The frame rate will be the best possible, but might not be as high as specified, especially if uploading via a  
slow connection.  
Scheduled Event  
A Scheduled event can be activated at preset times, in a repeating pattern on selected weekdays.

Motion Detection  
Motion detection is used to generate an alarm whenever movement occurs (or stops) in the video image. A total  
of 10 Include and/or Exclude windows can be configured.  
• Included windows target  
specific areas within the  
whole video image  
• Excluded windows define  
areas within an Include  
window that should be  
ignored (areas outside  
Include windows are auto-  
matically ignored)  
Once configured, the motion  
detection windows will appear in the  
list of available triggers, for  
triggering events. See How to set up  
a triggered event above.  
Note: Using the motion detection feature may decrease the camera’s overall performance.

AXIS 211M - System Options  
System Options  
Security  
User access control is enabled by default, when the administrator sets the root password on first access. An  
administrator can set up other users, by giving these user names and passwords. It is also possible to allow  
anonymous viewer login, which means that anybody may access the Live View page, as described below:  
Users - the user list displays the authorized users and user groups (levels):  
Viewer  
Provides the lowest level of access, which only allows access to the Live View page.  
Operator  
An operator can view the Live View page, create and modify event types and adjust certain  
other settings. Operators have no access to the System Options.  
Administrator  
An administrator has unrestricted access to all the setup tools and can determine the  
registration of all other users.  
User Settings - check the relevant check boxes to enable:  
• Anonymous viewer login - allows any viewer direct access to the Live View page.  
• Maximum number of simultaneous viewers - enter a value here to restrict the number of unicast viewers  
accessing the unit. This is useful if you need to save on bandwidth. (Note that all multicast viewers count as  
1 viewer.)  
IP Address Filtering  
Checking the Enable IP address filtering box enables the IP address filtering function, whereby the IP addresses  
in the list of filtered addresses will be allowed or denied access to the AXIS 211M.  
Up to 256 IP address entries may be specified (a single entry can contain multiple IP addresses). All other IP  
addresses not in this list will be allowed or denied access accordingly, i.e. if the addresses in the list are allowed,  
then all others are denied access, and vice versa. Click the Add button to add new filtered addresses. See also the  
online help for more information.  
Referrals - To prevent unauthorized clients from including the video stream from the cameras into external  
Web pages, check the Referrals checkbox and enter the IP address or Host name of the computer that hosts the  
Web pages with the included video stream. Several IP addresses/host names can be defined and are separated by  
semicolons (;). This option is only applicable to Motion JPEG video streams.  
Notes: If the referrals feature is enabled and you wish to also allow normal access to the Live View page, the product's own IP address or host  
name must be added to the list of allowed referrers.  
Restricting referrers has no effect on an MPEG-4 video stream. To restrict an MPEG-4 stream, IP address filtering must be enabled.  
Restricting referrers is of greatest value when not using IP address filtering. If IP address filtering is used, then the allowed referrers  
are automatically restricted to those allowed IP addresses.  
HTTPS  
The AXIS 211M supports encrypted browsing using HTTPS.  
A self-signed certificate can be used until a Certificate Authority-issued certificate has been obtained. Click the  
Create self-signed Certificate button to install a self-signed certificate. Although self-signed certificates are free  
and offer some protection, true security will only be implemented after the installation of a signed certificate  
issued by a certificate authority.  
A signed certificate can be obtained from an issuing Certificate Authority by clicking the Create Certificate  
Request button. When the signed certificate is returned, click the Install signed certificate button to import the  
certificate. The properties of any certificate request currently resident in the camera or installed can also be  
viewed by clicking the Properties... button. The HTTPS Connection Policy must also be set in the drop-down  
lists to enable HTTPS in the camera. For more information, please refer to the online help.

AXIS 211M - System Options  
802.1X - Network Admission Control  
IEEE 802.1X is an IEEE standard for port-based Network Admission Control. It provides authentication to  
devices attached to a network port (wired or wireless), establishing a point-to-point connection, or, if  
authentication fails, preventing access on that port. 802.1X is based on EAP (Extensible Authentication  
Protocol).  
In an 802.1X enabled network switch, clients equipped with the correct software can be authenticated and  
allowed or denied network access at the Ethernet level.  
Clients and servers in an 802.1X network may need to authenticate each other by some means. In the Axis  
implementation this is done with the help of digital certificates provided by a Certification Authority. These are  
then validated by a third-party entity, such as a RADIUS server, examples of which are FreeRADIUS and  
Microsoft Internet Authentication Service.  
To perform the authentication, the RADIUS server uses various EAP methods/protocols, of which there are  
many. The one used in the Axis implementation is EAP-TLS (EAP-Transport Layer Security).  
The AXIS network video device presents its certificate to the network switch, which in turn forwards this to the  
RADIUS server. The RADIUS server validates or rejects the certificate and responds to the switch, and sends its  
own certificate to the client for validation. The switch then allows or denies network access accordingly, on a  
preconfigured port.  
The authentication process  
1. A CA server provides the required signed certificates.  
2. The Axis video device requests access to the protected network at the network switch. The switch  
forwards the video device’s CA certificate to the RADIUS server, which then replies to the switch.  
3. The switch forwards the RADIUS server’s CA certificate to the video device, which also replies to the  
switch.  
4. The switch keeps track of all responses to the validation requests. If all certificates are validated, the  
Axis video device is allowed access to the protected network via a preconfigured port.  
RADIUS (Remote Authentication Dial In User Service) - AAA (Authentication, Authorization and Accounting)  
protocol for applications such as network access or IP mobility. It is intended to work in both local and roaming  
situations.  
CA servers - In cryptography, a Certification Authority (CA) is an entity that provides signed digital certificates  
for use by other parties, thus acting a trusted third party. There are many commercial CA’s that charge for their  
services. Institutions and governments may have their own CA, and there are free CA’s available.  
Date & Time  
Current Server Time - displays the current date and time (24h clock). The time can be displayed in 12h clock  
format in the Overlay (see below).  
New Server Time - Select your time zone from the drop-down list. If you want the server clock to automatically  
adjust for daylight savings time, select the Automatically adjust for daylight saving time changes.  
From the Time Mode section, select the preferred method to use for setting the time:  
• Synchronize with computer time - sets the time from the clock on your computer.  
• Synchronize with NTP Server - the camera will obtain the time from an NTP server every 60 minutes.  
The NTP Server can be set under Network > TCP/IP > Advanced or click on the No server specified  
link, see NTP Configuration, on page 29.  
• Set manually - this option allows you to manually set the time and date.  
Date & Time Format Used in Images - specify the formats for the date and time (12h or 24h) displayed in the  
video streams.

AXIS 211M - System Options  
Use the predefined formats or use your own custom date and time formats. See Advanced File Naming &  
Date/Time Formats in the online help  
for information on how to create your own file formats.  
Network - Basic TCP/IP Settings  
IP Address Configuration  
The AXIS 211M supports both IP version 4 and IP version 6. Both versions may be enabled simultaneously, and  
at least one version must always be enabled.  
When using IPv4, the IP address for the AXIS 211M can be set automatically via DHCP, or a static IP address  
can be set manually.  
If IPv6 is enabled, the AXIS 211M will receive an IP address according to the configuration in the network  
router.  
There are also options for setting up notification of changes in the IP address, and for using the AXIS Internet  
Dynamic DNS Service. For more information on setting the IP address, please see the online help.  
Notes:  
•DHCP is a protocol for automatic IP address assignment on a network. IP address assignment via DHCP may lead to the  
situation where the IP address changes and you lose contact with the camera. Configure the options for notification of IP  
address change (under Services) to receive notification from the camera when the IP address changes.  
•Alternatively, if your DHCP server can update a DNS server, you can access the AXIS 211M by host name which is always  
the same, regardless of the IP address.  
Services  
Enable ARP/Ping setting of IP address - The IP address can be set using the ARP/Ping method, which associates  
the unit's MAC address with an IP address. Check this box to enable the service. Leave disabled to prevent  
unintentional resetting of the IP address.  
Notes: •The ARP/Ping service is automatically disabled 2 minutes after the unit is started, or as soon as an IP address is set.  
•Pinging the unit will still be possible when this service is disabled.  
Options for notification of IP address change - If the IP address for the camera changes, e.g. automatically by  
DHCP, you can choose to be notified of the change. Click Settings... and enter the required information.  
AXIS Internet Dynamic DNS Service - Use the AXIS Internet Dynamic DNS service to assign a host name for  
easy access to your AXIS 211M Network Camera (requires Internet access).  
Click Settings... to register the AXIS 211M with the Axis Internet Dynamic DNS service, or to modify the  
existing settings (requires access to the Internet). The domain name currently registered at the Axis Internet  
Dynamic DNS service for your product can at any time be removed.  
For more information, please refer to the online help.  
Network - Advanced TCP/IP Settings  
DNS Configuration  
DNS (Domain Name Service) provides the translation of host names to IP addresses on your network.  
Obtain DNS server address via DHCP - automatically use the DNS server settings provided by the DHCP server.  
Click the View button to see the current settings.

AXIS 211M - System Options  
Use the following DNS server address - enter the desired DNS server by specifying the following:  
Domain name - enter the domain(s) to search for the host name used by the AXIS 211M. Multiple domains can  
be separated by semicolons (;). The host name is always the first part of a Fully Qualified Domain Name, e.g.  
myserver is the host name in the Fully Qualified Domain Name myserver.mycompany.com where  
mycompany.com is the Domain name.  
DNS servers - enter the IP addresses of the primary and secondary DNS servers.  
NTP Configuration  
Obtain NTP server address via DHCP - check this radio button to automatically look up and use the NTP server  
settings as provided by DHCP. Click the View button to see the current settings.  
Use the following NTP server address - to make manual settings, check this radio button and enter the host  
name or IP address of the NTP server.  
Note: If using a host name for the NTP server, a DNS server must be configured under TCP/IP settings. See Network > TCP/IP below.  
Host Name Configuration  
The AXIS 211M can be accessed using a host name, instead of an IP address. The host name is usually the same  
as the assigned DNS Name. For more information, see the online help.  
Link-Local IPv4 Address  
This is enabled by default and assigns the AXIS 211M an additional IP address for use with UPnP™. The AXIS  
211M can have both a Link-Local IP and a static/DHCP-supplied IP address at the same time - these will not  
affect each other.  
HTTP  
The default HTTP port number (80) can be changed to any port within the range 1024-65535. This is useful for,  
e.g. simple security port mapping.  
HTTPS  
If applicable, enter the HTTPS port the AXIS 211M will use. The default setting (443) can be changed to any port  
within the range 1024-65535. HTTPS is used to provide encrypted web browsing.  
NAT traversal (port mapping)  
A broadband router allows devices on a private network (LAN) to share a single connection to the Internet. This  
is done by forwarding network traffic from the private network to the “outside” i.e. the Internet. Security on the  
private network (LAN) is increased since most broadband routers are pre-configured to stop any attempts to  
access the private network (LAN) from the public network/Internet.  
Use NAT traversal when your AXIS 211M is located on an intranet (LAN) and you wish to make it available  
from the other (WAN) side of a NAT router. With NAT traversal properly configured, all HTTP traffic to an  
external HTTP port in the NAT router will be forwarded to the camera.

AXIS 211M - System Options  
Notes:  
•
•
For NAT traversal to work, this must also be supported by the broadband router.  
The broadband router has many different names: “NAT router”, “Network router“, Internet Gateway”, “Broadband  
sharing device” or “Home firewall” but the essential purpose of the device is the same.  
Enable/Disable - When enabled, the AXIS 211M will attempt to configure port mapping in a NAT router on  
your network, using UPnP™. Note that UPnP™ must be enabled in the camera (see System Options > Network >  
UPnP™).  
Use manually selected NAT router - Select this option to manually select a NAT router and enter the IP address  
for the router in the field provided.  
If a router is not manually specified, the AXIS 211M will automatically search for NAT routers on your network.  
If more than one router is found, the default router will be selected.  
Alternative HTTP port - Select this option to manually define an external HTTP port. Enter the port number in  
the field provided. If no port is entered here a port number will automatically be selected when NAT traversal is  
enabled.  
Notes: •An alternative HTTP port can be used/be active even if NAT traversal is disabled. This is useful if, e.g. your NAT router does  
not support UPnP™ and you need to manually configure port forwarding in the NAT router.  
•If a manually selected port is already in use, another will automatically be selected.  
•When the port is selected automatically it will be displayed in this field. This can be changed by entering a new port  
number and clicking Save.  
FTP  
The FTP server running in the AXIS 211M enables the upload of, e.g. new firmware, user applications, etc.  
Check the box to enable the service.  
RTSP  
The RTSP protocol allows a connecting client to start an MPEG-4 stream. Check the box to enable the service  
and enter the RTSP port number to use. The default setting (554) can be changed to any port within the range  
1024-65535.  
Network Traffic  
Connection Type - The default setting is Auto-negotiate, which means that the correct speed is automatically  
selected. If necessary, you can set the connection speed by selecting it from the drop-down list.  
SOCKS  
SOCKS is a networking proxy protocol. The AXIS 211M can be configured to use a SOCKS server to reach  
networks on the other side of a firewall/proxy server. This functionality is useful if the AXIS 211M is located on  
a local network behind a firewall, but notifications, uploads, alarms, etc., need to be sent to a destination outside  
the local network (e.g. to the Internet).  
QoS (Quality of Service)  
Quality of Service (QoS) provides the means to guarantee a certain level of a specified resource to selected traffic  
on a network. Quality can be defined as, e.g. a maintained level of bandwidth, low latency, no packet losses, etc.  
The main benefits of a QoS-aware network can be summarized as:  
•The ability to prioritize traffic and thus allow critical flows to be served before flows with lesser priority.  
•Greater reliability in the network, thanks to the control of the amount of bandwidth an application may use,  
and thus control over bandwidth races between applications.  
The QoS in Axis network video products marks the data packets for various types of network traffic originating  
from the product. This makes it possible for network routers and switches to, e.g. reserve a fixed amount of  
bandwidth for these types of traffic. The types of traffic marked by the camera are video, audio, event/alarm and  
management network traffic.

AXIS 211M - System Options  
QoS DSCP Settings  
For each type of network traffic supported by your Axis network video product, enter a DSCP (Differentiated  
Services Codepoint) value. This value is used to mark the traffic’s IP header. When the marked traffic reaches a  
network router or switch, the DSCP value in the IP header tells the router or switch which type of treatment to  
apply to this type of traffic, for example, how much bandwidth to reserve for it.  
Note that DSCP values can be entered in decimal or hexadecimal format, but saved values are always shown in  
decimal. For more information on Quality of Service, please see the Axis support web at www.axis.com/techsup  
SMTP (email)  
Enter the host names or addresses for your primary and secondary mail servers in the fields provided, to enable  
the sending of notifications and image/video email messages from the camera to predefined addresses via SMTP.  
If your mail server requires authentication, check the box for Use authentication to log in to this server and  
enter the necessary information.  
SNMP  
The Simple Network Management Protocol (SNMP) allows remote management of network devices. Depending  
on the level of security required, select the version of SNMP to use. The three levels of security are:  
• SNMP V1 - includes no security.  
• SNMP V2c - uses very simple security. The community name can be specified as a password for read or  
read/write access to all supported SNMP objects. The community is the group of network devices using  
SNMP.  
• SNMP V3 - provides encryption and secure passwords. HTTPS must be enabled.  
UPnP™  
The camera includes support for UPnP™, which is enabled by default. If also enabled on your computer, the  
camera will automatically be detected and a new icon will be added to “My Network Places.”  
Note: UPnP™must also be enabled on your operating system. Refer to your operating systems help or user manual for more information.  
RTP / MPEG-4  
These settings are the port range, IP address, port number (video and audio), and Time-To-Live value to use for  
the video stream(s) in multicast MPEG-4 format. Only certain IP addresses and port numbers should be used for  
multicast streams. For more information, please see the online help.  
Bonjour  
The AXIS 211M includes support for Bonjour. When enabled, the camera is automatically detected by operating  
systems and clients that support this.  
Ports & Devices  
I/O Ports - the pinout, interface support and the control and monitoring functions provided by this connector  
are described in I/O Terminal Connector, on page 34.  
LED Settings  
The Network Indicator LED can be enabled or disabled, according to requirements and the Status indicator LED  
can be set to flash at a configurable interval (or to not light up at all) whenever the unit is accessed. For a listing  
of all LED behavior, see page 7, or the online help.  
Note that the Status LED does not flash when the stream is retrieved using MPEG-4 multicast.

AXIS 211M - Troubleshooting  
Troubleshooting  
Checking the Firmware  
Firmware is software that determines the functionality of the AXIS 211M. One of your first actions when  
troubleshooting a problem should be to check the currently installed firmware version. The latest version may  
contain a correction that fixes your particular problem. The current firmware version in your camera can be  
seen on the page Setup > Basic Configuration.  
Upgrading the Firmware  
When you upgrade the firmware with a file from the Axis Web site, your Axis camera will receive the latest  
available functionality. Always read the upgrade instructions and release notes available with each new release,  
before updating the firmware.  
Note: Preconfigured and customized settings will be saved when the firmware is upgraded (providing the features are available in the new  
firmware) although this is not guaranteed by Axis Communications.  
1. Save the firmware file to your computer. The latest version of the firmware is available free of charge  
from the Axis Web site at www.axis.com/techsup  
2. Go to Setup > System Options > Maintenance in the camera’s Web pages.  
3. In the Upgrade Server section, browse to the desired firmware file on your computer. Click Upgrade.  
Notes: •After starting the upgrade process, always wait at least 5-10 minutes before restarting the camera, even if you suspect  
the upgrade has failed.  
•Your dealer reserves the right to charge for any repair attributable to faulty upgrading by the user.  
•Always read the upgrade instructions available with each new release, before updating the firmware.  
Emergency Recovery Procedure  
If power to the camera is lost during the upgrade, the process will fail and the unit will become unresponsive. A  
flashing red Status LED indicates a failed upgrade. To recover the unit, follow the steps below. The serial number  
is found on the label attached to the bottom of the camera.  
1.  
Unix/Linux -From the command line, type the following:  
arp -s <IP address of camera> <Serial number> temp  
ping -s 408 <IP address of camera>  
Windows - From a command/DOS prompt, type the following:  
arp -s <IP address of camera> <Serial number>  
ping -l 408 -t <IP address of camera>  
If the unit does not reply within a few seconds, restart it and wait for a reply. Press CTRL+C to stop Ping.  
2. Open a browser and type in the camera’s IP address. In the page that appears, use the Browse button to  
select the upgrade file to use, e.g. axis211m.bin. Then click the Load button to restart the upgrade process.  
3. After the upgrade has completed (1-10 minutes), the unit will automatically restart and show a steady green  
on the Power and Status LEDs and flashing green or amber on the Network LED.

AXIS 211M - Troubleshooting  
Axis Support  
If you contact Axis support, please help us to help you solve your problems, by providing the server report, the  
log file and a brief description of the problem.  
Server Report - go to Setup > System Options > Support Overview. The server report contains important  
information about the server and its software, as well as a list of the current parameters.  
The Log file is available from Setup > System Options > Logs & Reports. The Log file records events in the unit  
since the last system restart and can be a useful diagnostic tool when troubleshooting.  
Symptoms, Possible Causes and Remedial Actions  
Problems setting the IP address  
When using ARP/Ping.  
Try the installation again. The IP address must be set within two minutes after running  
the ARP command. Ensure the Ping length is set to 408.  
The camera is located on a different  
subnet.  
If the IP address intended for the camera and the IP address of your computer are  
located on different subnets, you will not be able to set the IP address. Contact your  
network administrator to obtain an appropriate IP address.  
The IP address is being used by another Disconnect the camera from the network. Run the Ping command. (In a Command/DOS  
device.  
window, type ping and the IP address of the unit).  
If you receive: Reply from <IP address>: bytes = 32; time = 10 ms..... - this means  
that the IP address is already in use on your network. You must obtain a new IP address  
and reinstall the unit.  
If you see: Request timed out - this means that the IP address is available for use with  
your camera. In this case, check all cabling and reinstall the unit.  
Possible IP address conflict with  
another device on the same subnet.  
The static IP address in the camera is used before the DHCP server sets a a dynamic  
address. This means that if the same default static IP address is also used by another  
device, there may be problems accessing the camera. To avoid this, set the static IP  
address to 0.0.0.0.  
The camera cannot be accessed from a Web browser  
The IP address has been changed by  
DHCP.  
1) Move the camera to an isolated network, or to one with no DHCP or BOOTP server.  
Set the IP address again, using the AXIS IP Utility (see the Installation Guide) or the  
ARP/Ping commands.  
2) Access the unit and disable DHCP in the TCP/IP settings. Return the unit to the main  
network. The unit now has a fixed IP address that will not change.  
3) As an alternative to 2), if dynamic IP address via DHCP or BOOTP is required, select  
the required service and then configure IP address change notification from the net-  
work settings. Return the unit to the main network. The unit will now have a dynamic  
IP address, but will notify you if the address changes.  
Proxy server.  
If using a proxy server, try disabling the proxy setting in your browser.  
Other networking problems.  
Test the network cable and connectors by connecting it to another network device,  
then Ping that device from your workstation. See the instructions above.  
Cannot log in.  
Check that you are using the proper password. If HTTPS is enabled, ensure that the cor-  
rect protocol (HTTP or HTTPS) is used when attempting to log in. You may need to man-  
ually type in http or https in the browser's address bar.  
Incorrect host name.  
Check that the host name and DNS server settings are correct. See the basic and  
advanced TCP/IP settings.  
Cannot send notifications, uploads, alarms, etc, to a destination outside the local network  
Firewall protection. The camera can be configured to use a SOCKS server to reach networks on the other  
side of a firewall/proxy server.  
Your camera is accessible locally, but not externally  
Firewall protection.  
Check the Internet firewall with your system administrator.  
Default routers required.  
Poor or intermittent network connection.  
Network switch.  
Check if you need to configure the default router settings.  
If using a network switch, check that the port on that device uses the same setting for  
the network connection type (speed/duplex) as set in the advanced TCP/IP settings.  
The Auto-Negotiate setting is recommended.

AXIS 211M - Technical Specifications  
General performance considerations  
When setting up your system, it is important to consider how various settings and situations will affect  
performance. Some factors affect the amount of bandwidth (the bit rate) required, others can affect the frame  
rate, and some will affect both. If the load on the CPU reaches its maximum, this will also affect the frame rate.  
The following factors are among the most important to consider:  
• High image resolutions and/or lower compression levels result in larger images. Bandwidth affected.  
• Access by large numbers of Motion JPEG and/or unicast MPEG-4 clients. Bandwidth affected.  
• Simultaneous viewing of different streams (resolution, compression, etc.) by different clients. Frame  
rate and bandwidth affected.  
• Accessing both Motion JPEG and MPEG-4 video streams simultaneously. Frame rate and bandwidth  
affected.  
• Heavy usage of event settings affects the camera’s CPU load. Frame rate affected.  
• Enabled motion detection. Frame rate and bandwidth affected.  
• Heavy network utilization due to poor infrastructure. Bandwidth affected  
• Viewing on poorly performing client PC’s lowers perceived performance. Frame rate affected.  
Optimizing your system  
To see the bandwidth and frame rate currently required by the video stream, the AXIS 211M provides a tool that  
can be used to display these values directly in the video image.  
To do this, special format strings are added as part of a text overlay.  
Simply add #r (average frame rate in fps) and/or #b (average bandwidth  
in kbps) to the overlay.  
For detailed instructions, please see the online help for Video & Image >  
Overlay Settings, and the help for File Naming & Date/Time Formats.

AXIS 211M - Glossary of Terms  
CGI (Common Gateway Interface) - A specification for communication  
Glossary of Terms  
802.1x - An IEEE standard for port-based Network Admission Control.  
It provides authentication to devices attached to a network port (wired  
or wireless), establishing a point-to-point connection, or, if  
authentication fails, preventing access on that port. 802.1x is based on  
EAP (Extensible Authentication Protocol).  
between a web server and other (CGI) programs. For example, a HTML  
page that contains a form might use a CGI program to process the form  
data once it is submitted.  
CIF (Common Intermediate Format) - CIF refers to the analog video  
resolutions 352x288 pixels (PAL) and 352x240 pixels (NTSC). See also  
Resolution.  
Client/Server - Client/server describes the relationship between two  
computer programs in which one program, the client, makes a service  
request from another program, the server, which fulfils the request.  
Typically, multiple client programs share the services of a common  
server program. A web browser is a client program that requests services  
(the sending of web pages or files) from a web server.  
ActiveX - A standard that enables software components to interact with  
one another in a networked environment, regardless of the language(s)  
used to create them. Web browsers may come into contact with ActiveX  
controls, ActiveX documents, and ActiveX scripts. ActiveX controls are  
often downloaded and installed automatically as required.  
AF (Autofocus) - A system by which the camera lens automatically  
focuses on a selected part of the subject.  
CMOS (Complementary Metal Oxide Semiconductor) - A CMOS is a  
widely used type of semiconductor that uses both negative and positive  
circuits. Since only one of the circuit types is on at any given time,  
CMOS chips require less power than chips using just one type of  
transistor. CMOS image sensors also allow processing circuits to be  
included on the same chip, an advantage not possible with CCD sensors,  
which are also much more expensive to produce.  
Angle - The field of view, relative to a standard lens in a 35mm still  
camera, expressed in degrees, e.g. 30°. For practical purposes, this is the  
area that a lens can cover, where the angle of view is determined by the  
focal length of the lens. A wide-angle lens has a short focal length and  
covers a wider angle of view than standard or telephoto lenses, which  
have longer focal lengths.  
Codec - In communications engineering, a codec is usually a  
coder/decoder. Codecs are used in integrated circuits or chips that  
convert, e.g. analog video and audio signals into a digital format for  
transmission. The codec also converts received digital signals back into  
analog format. A codec uses analog-to-digital conversion and  
digital-to-analog conversion in the same chip.  
ARP (Address Resolution Protocol) - This protocol is used to associate  
an IP address to a hardware MAC address. A request is broadcast on the  
local network to discover the MAC address for an IP address.  
ARTPEC (Axis Real Time Picture Encoder) - This chip is used for image  
compression.  
Codec can also mean compression/decompression, in which case it is  
generally taken to mean an algorithm or computer program for reducing  
the size of large files and programs.  
ASIC (Application Specific Integrated Circuit) - A circuit designed for  
a specific application, as opposed to a general purpose circuit, such as a  
microprocessor.  
Compression - See Image Compression.  
Aspect ratio - A ratio of width to height in images. A common aspect  
ratio used for television screens and computer monitors is 4:3.  
High-definition television (HDTV) uses an aspect ratio of 9:16.  
Contrast - Defines the degree of difference between the lightest and  
darkest parts of an image or video stream.  
Autoiris (or DC-Iris) - This special type of iris is electrically controlled  
by the camera, to automatically regulate the amount of light allowed to  
enter.  
DC-Iris - This special type of iris is electrically controlled by the  
camera, to automatically regulate the amount of light allowed to enter.  
DHCP (Dynamic Host Configuration Protocol) - DHCP is a protocol  
that lets network administrators automate and centrally manage the  
assignment of Internet Protocol (IP) addresses to network devices in a  
network.  
AVI (Audio Video Interleave) - A video format that supports  
simultaneous playback of audio and video.  
Bitmap - A bitmap is a data file representing a rectangular grid of  
pixels. It defines a display space and color for each pixel (or "bit") in the  
display space. This type of image is known as a "raster graphic." GIF's  
and JPEG's are examples of image file types that contain bitmaps.  
DHCP uses the concept of a "lease" or amount of time that a given IP  
address will be valid for a computer. The lease time can vary, depending  
on how long a user is likely to require the network connection at a  
particular location.  
Because a bitmap uses this fixed raster method, it cannot easily be  
rescaled without losing definition. Conversely, a vector graphic image  
uses geometrical shapes to represent the image, and can thus be quickly  
rescaled.  
DHCP also supports static addresses for, e.g. computers running web  
servers, which need a permanent IP address.  
DNS (Domain Name System) - DNS is used to locate and translate  
Internet domain names into IP (Internet Protocol) addresses. A domain  
name is a meaningful and easy-to-remember name for an Internet  
address. For example the domain name www.example.com is much  
easier to remember than 192.0.34.166. The translation tables for domain  
names are contained in Domain name servers.  
Bit rate - The bit rate (in kbit/s or Mbit/s) is often referred to as speed,  
but actually defines the number of bits/time unit and not distance/time  
unit.  
Bluetooth - Bluetooth is an open standard for wireless transmission of  
AXIS COMMUNICATIONS  
voice and data between mobile devices (PCs, handheld computers,  
<Product Name> Quick User’s Guide  
telephones and printers).  
Domain Server - Domains can also be used by organizations who wish  
to centralize the management of their (Windows) computers. Each user  
within a domain has an account that usually allows them to log in to  
and use any computer in the domain, although restrictions may also  
apply. The domain server is the server that authenticates the users on  
the network.  
Bonjour - Also known as zero-configuration networking, Bonjour  
enables devices to automatically discover each other on a network,  
without having to enter IP addresses or configure DNS servers. Bonjour  
is a trademark of Apple Computer, Inc.  
Broadband - In network engineering terms, this describes transmission  
methods where two or more signals share the same carrier. In more  
popular terminology, broadband is taken to mean high-speed data  
transmission.  
Duplex - See Full-duplex.  
Ethernet - Ethernet is the most widely installed local area network  
technology. An Ethernet LAN typically uses special grades of twisted  
pair wires. The most commonly installed Ethernet systems are 10BASE-T  
and 100BASE-T10, which provide transmission speeds up to 10 Mbps  
and 100 Mbps respectively.  
CCD (Charged Coupled Device) - This light-sensitive image device used  
in many digital cameras is a large integrated circuit that contains  
hundreds of thousands of photo-sites (pixels) that convert light energy  
into electronic signals. Its size is measured diagonally and can be 1/4",  
1/3", 1/2" or 2/3".  
ETRAX (Ethernet Token Ring AXIS) - Axis' own microprocessor.

Factory default settings - These are the settings that originally applied  
Hub - A (network) hub is used to connect multiple devices to the  
network. The hub transmits all data to all devices connected to it,  
whereas a switch will only transmit the data to the device it is  
specifically intended for.  
for a device when it was first delivered from the factory. If it should  
become necessary to reset a device to its factory default settings, this  
will, for many devices, completely reset any settings that were changed  
by the user.  
IEEE 802.11 - A family of standards for wireless LANs. The 802.11  
standard supports 1 or 2 Mbit/s transmission on the 2.4 GHz band. IEEE  
802.11b specifies an 11 Mbit/s data rate on the 2.4 GHz band, while  
802.11a allows up to 54 Mbit/s on the 5 GHz band.  
Firewall - A firewall works as a barrier between networks, e.g. between  
a Local Area Network and the Internet. The firewall ensures that only  
authorized users are allowed to access the one network from the other. A  
firewall can be software running on a computer, or it can be a  
standalone hardware device.  
Image compression - Image compression minimizes the file size (in  
bytes) of an image. Two of the most common compressed image formats  
are JPEG and GIF.  
Focal length - Measured in millimeters, the focal length of a camera  
lens determines the width of the horizontal field of view, which in turn  
is measured in degrees.  
Interlacing - Interlaced video is video captured at 50 pictures (known as  
fields) per second, of which every 2 consecutive fields (at half height)  
are then combined into 1 frame. Interlacing was developed many years  
ago for the analog TV world and is still used widely today. It provides  
good results when viewing motion in standard TV pictures, although  
there is always some degree of distortion in the image.  
FTP (File Transfer Protocol) - An application protocol that uses the  
TCP/IP protocols. It is used to exchange files between computers/devices  
on networks.  
Frame - A frame is a complete video image. In the 2:1 interlaced  
scanning format of the RS-170 and CCIR formats, a frame is made up of  
two separate fields of 262.5 or 312.5 lines interlaced at 60 or 50 Hz to  
form a complete frame, which appears at 30 or 25 Hz. In video cameras  
with a progressive scan, each frame is scanned line-by-line and not  
interlaced; most are also displayed at 30 and 25 Hz.  
To view interlaced video on, e.g. a computer monitor, the video must  
first be de-interlaced, to produce progressive video, which consists of  
complete images, one after the other, at 25 frames per second. See also  
Progressive scan.  
IP (Internet Protocol) - The Internet Protocol is a method transmitting  
data over a network. Data to be sent is divided into individual and  
completely independent "packets." Each computer (or host) on the  
Internet has at least one address that uniquely identifies it from all  
others, and each data packet contains both the sender's address and the  
receiver's address.  
Frame rate - The frame rate used to describe the frequency at which a  
video stream is updated is measured in frames per second (fps). A higher  
frame rate is advantageous when there is movement in the video stream,  
as it maintains image quality throughout.  
Full-duplex - Transmission of data in two directions simultaneously. In  
an audio system this would describe, e.g. a telephone systems.  
Half-duplex also provides bi-directional communication, but only in one  
direction at a time, as in a walkie-talkie system. See also Simplex.  
The Internet Protocol ensures that the data packets all arrive at the  
intended address. As IP is a connectionless protocol, which means that  
there is no established connection between the communication  
end-points, packets can be sent via different routes and do not need to  
arrive at the destination in the correct order.  
Gain - Gain is the amplification factor and the extent to which an  
analog amplifier boosts the strength of a signal. Amplification factors  
are usually expressed in terms of power. The decibel (dB) is the most  
common way of quantifying the gain of an amplifier.  
Once the data packets have arrived at the correct destination, another  
protocol - Transmission Control Protocol (TCP) - puts them in the right  
order. See also TCP.  
Gateway - A gateway is a point in a network that acts as an entry point  
to another network. In a corporate network for example, a computer  
server acting as a gateway often also acts as a proxy server and a  
firewall server. A gateway is often associated with both a router, which  
knows where to direct a given packet of data that arrives at the gateway,  
and a switch, which furnishes the actual path in and out of the gateway  
for a given packet.  
IP Address - An IP address is simply an address on an IP network used  
by a computer/device connected to that network. IP addresses allow all  
the connected computers/devices to find each other and to pass data  
back and forth.  
To avoid conflicts, each IP address on any given network must be  
unique. An IP address can be assigned as fixed, so that it does not  
change, or it can be assigned dynamically (and automatically) by DHCP.  
GIF (Graphics Interchange Format) - GIF is one of the most common  
file formats used for images in web pages. There are two versions of the  
format, 87a and 89a. Version 89a supports animations, i.e. a short  
sequence of images within a single GIF file. A GIF89a can also be  
specified for interlaced presentation.  
An IP address consists of four groups (or quads) of decimal digits  
separated by periods, e.g. 130.5.5.25. Different parts of the address  
represent different things. Some part will represent the network number  
or address, and some other part will represent the local machine address.  
GOV (Group Of VOPs) - A group of VOP's is the basic unit of an  
MPEG-4 video stream. The GOV contains different types and numbers of  
VOP's (I-VOP's, P-VOP's, etc) as determined by the GOV length and GOV  
structure. See also VOP.  
See also IP (Internet Protocol).  
I-VOP - See VOP.  
IPv6 (Internet Protocol version 6) - A set of specifications designed as  
improvements to the current IP Version 4. Network hosts and  
intermediate nodes with either IPv4 or IPv6 can handle packets for  
either level of the Internet Protocol.

GOV length - The GOV length determines the number of images (VOP's)  
in the GOV structure. See also GOV and VOP.  
GOV structure - The GOV structure describes the composition of an  
MPEG-4 video stream, as regards the type of images (I-VOP's or  
P-VOP's) included in the stream, and their internal order. See also GOV  
and VOP.  
JPEG (Joint Photographic Experts Group) - Together with the GIF file  
format, JPEG is an image file type commonly used on the web. A JPEG  
image is a bitmap, and usually has the file suffix '.jpg' or ".jpeg." When  
creating a JPEG image, it is possible to configure the level of  
compression to use. As the lowest compression (i.e. the highest quality)  
results in the largest file, there is a trade-off between image quality and  
file size.  
Half-duplex - See Full-duplex.  
HTML (Hypertext Markup Language) - HTML is the set of "markup"  
symbols or codes inserted in a file intended for display in web browser.  
The markup tells the browser how to display the page's words and  
images for the user.  
kbit/s (kilobits per second) - A measure of the bit rate, i.e. the rate at  
which bits are passing a given point. See also Bit rate.  
HTTP (Hypertext Transfer Protocol) - HTTP is the set of rules for  
exchanging files (text, graphic images, sound, video, and other  
multimedia files) on the web. The HTTP protocol runs on top of the  
TCP/IP suite of protocols.  
LAN (Local Area Network) - A LAN is a group of computers and  
associated devices that typically share common resources within a  
limited geographical area.

electronic mail. The PEM-format is often used for representing an  
HTTPS certificate or certificate request.  
family. Because of its robustness and availability, Linux has won  
popularity in the open source community and among commercial  
application developers.  
Ping - Ping is a basic network program used diagnostically to check  
the status of a network host or device. Ping can be used to see if a  
particular network address (IP address or host name) is occupied or not,  
or if the host at that address is responding normally. Ping can be run  
from, e.g. the Windows Command prompt or the command line in Unix.  
MAC address (Media Access Control address) - A MAC address is a  
unique identifier associated with a piece of networking equipment, or  
more specifically, its interface with the network. For example, the  
network card in a computer has its own MAC address.  
Manual iris - This is the opposite to an autoiris, i.e. the camera iris must  
be adjusted manually to regulate the amount of light allowed to reach  
the image sensor.  
Pixel - A pixel is one of the many tiny dots that make up a digital  
image. The color and intensity of each pixel represents a tiny area of the  
complete image.  
Mbit/s (Megabits per second) - A measure of the bit rate, i.e. the rate at  
which bits are passing a given point. Commonly used to give the "speed"  
of a network. A LAN might run at 10 or 100 Mbit/s. See also Bit rate.  
PoE (Power over Ethernet) - Power over Ethernet provides power to a  
network device via the same cable as used for the network connection.  
This is very useful for IP-Surveillance and remote monitoring  
applications in places where it may be too impractical or expensive to  
power the device from a power outlet.  
Monitor - A monitor is very similar to a standard television set, but  
lacks the electronics to pick up regular television signals.  
PPP (Point-to-Point Protocol) - A protocol that uses a serial interface  
for communication between two network devices. For example, a PC  
connected by a phone line to a server.  
Motion JPEG - Motion JPEG is a simple compression/decompression  
technique for networked video. Latency is low and image quality is  
guaranteed, regardless of movement or complexity of the image. Image  
quality is controlled by adjusting the compression level, which in turn  
provides control over the file size, and thereby the bit rate.  
PPTP (Point-to-Point tunneling Protocol) - A protocol (set of  
communication rules) that allows corporations to extend their own  
corporate network through private "tunnels" over the public Internet. In  
this way a corporation can effectively use a WAN (Wide Area Network)  
as a large single LAN (Local Area Network). This kind of interconnection  
is known as a virtual private network (VPN).  
High-quality individual images from the Motion JPEG stream are easily  
extracted. See also JPEG.  
Megapixel - See Pixel.  
MPEG (Moving Picture Experts Group) - The Moving Picture Experts  
Group develops standards for digital video and audio compression. It  
operates under the auspices of the International Organization for  
Standardization (ISO). The MPEG standards are an evolving series, each  
designed for a different purpose.  
Pre/post alarm images - The images from immediately before and after  
an alarm. These images are stored in a buffer for later retrieval.  
Progressive scan - Progressive scan, as opposed to interlaced video,  
scans the entire picture, line by line every sixteenth of a second. In other  
words, captured images are not split into separate fields as in interlaced  
scanning.  
MPEG-2 - MPEG-2 is the designation for a group of audio and video  
coding standards, and is typically used to encode audio and video for  
broadcast signals, including digital satellite and Cable TV. MPEG-2, with  
some modifications, is also the coding format used by standard  
commercial DVD movies.  
Computer monitors do not need interlace to show the picture on the  
screen, but instead show them progressively, on one line at a time in  
perfect order, i.e. 1, 2, 3, 4, 5, 6, 7 etc., so there is virtually no  
"flickering" effect. In a surveillance application, this can be critical  
when viewing detail within a moving image, such as a person running.  
A high-quality monitor is required to get the best from progressive scan.  
See also Interlacing.  
MPEG-4 - MPEG-4 is a group of audio and video coding standards and  
related technology. The primary uses for the MPEG-4 standard are web  
(streaming media) and CD distribution, conversational (videophone), and  
broadcast television.  
Protocol - A special set of rules governing how two entities will  
communicate. Protocols are found at many levels of communication,  
and there are hardware protocols and software protocols.  
Most of the features included in MPEG-4 are left to individual  
developers to decide whether to implement them or not. This means that  
there are probably no complete implementations of the entire MPEG-4  
set of standards. To deal with this, the standard includes the concept of  
"profiles" and "levels", allowing a specific set of capabilities to be  
defined in a manner appropriate for a subset of applications.  
Proxy server - In an organization that uses the Internet, a proxy server  
acts as an intermediary between a workstation user and the Internet.  
This provides security, administrative control, and a caching service.  
Any proxy server associated with a gateway server, or part of a gateway  
server, effectively separates the organization’s network from the outside  
network and the local firewall. It is the firewall server that protects the  
network against outside intrusion.  
Multicast - Bandwidth-conserving technology that reduces bandwidth  
usage by simultaneously delivering a single stream of information to  
multiple network recipients.  
Multiplexer - A multiplexer is a high-speed switch that provides  
A proxy server receives requests for Internet services (such as web page  
requests) from many users. If the proxy server is also a cache server, it  
looks in its local cache of previously downloaded web pages. If it finds  
the page, it is returned to the user without forwarding the request to the  
Internet. If the page is not in the cache, the proxy server, acting as a  
client on behalf of the user, uses one of its own IP addresses to request  
the page from another server over the Internet. When the requested page  
is returned, the proxy server forwards it to the user that originally  
requested it.

playback everything that happened on any one camera with no  
interference from the other cameras on the system.  
Network connectivity - The physical (wired or wireless) and logical  
(protocol) connection of a computer network or an individual device to a  
network, such as the Internet or a LAN.  
NTSC (National Television System Committee) - NTSC is the television  
and video standard in the United States. NTSC delivers 525 lines at 60  
half-frames/second.  
P-VOP - See VOP.  
Quality of Service (QoS) - QoS provides the means to guarantee a certain  
level of a specified resource to selected traffic on a network. Quality can  
be defined as, e.g. a maintained level of bandwidth, low latency, no  
packet losses, etc.  
OEM (Original Equipment Manufacturer) - This is a designation for  
companies that manufacture equipment which is then marketed and sold  
to other companies under their own names.  
PAL (Phase Alternating Line) - PAL is the dominant television  
Resolution - Image resolution is a measure of how much detail a digital  
image can hold: the greater the resolution, the greater the level of detail.  
Resolution can be specified as the number of pixel-columns (width) by  
the number of pixel-rows (height), e.g. 320x240.  
standard in Europe. PAL delivers 625 lines at 50 half-frames/second.

Alternatively, the total number of pixels (usually in megapixels) in the  
image can be used. In analog systems it is also common to use other  
format designations, such as CIF, QCIF, 4CIF, etc.  
Subnet/subnet mask - A subnet is an identifiably separate part of an  
organization's network. Typically, a subnet may represent all the  
machines at one geographic location, in one building, or on the same  
local area network (LAN). Having an organization's network divided  
into subnets allows it to be connected to the Internet with a single  
shared network address.  
RTCP (Real-Time Control Protocol) - RTCP provides support for  
real-time conferencing of groups of any size within an intranet. This  
support includes source identification and support for gateways like  
audio and video bridges as well as multicast-to-unicast translators.  
The subnet mask is the part of the IP address that tells a network router  
how to find the subnet that the data packet should be delivered to. Using  
a subnet mask saves the router having to handle the entire 32-bit IP  
address; it simply looks at the bits selected by the mask.  
RTCP offers quality-of-service feedback from receivers to the multicast  
group as well as support for the synchronization of different media  
streams.  
Switch - A switch is a network device that connects network segments  
together, and which selects a path for sending a unit of data to its next  
destination. In general, a switch is a simpler and faster mechanism than  
a router, which requires knowledge about the network and how to  
determine the route. Some switches include the router function. See also  
Router.  
RTP (Real-Time Transport Protocol) - RTP is an Internet protocol for  
the transport of real-time data, e.g. audio and video. It can be used for  
media-on-demand as well as interactive services such as Internet  
telephony.  
RTSP (Real Time Streaming Protocol) - RTSP is a control protocol, and  
a starting point for negotiating transports such as RTP, multicast and  
Unicast, and for negotiating codecs.  
TCP (Transmission Control Protocol) - TCP is used along with the  
Internet Protocol (IP) to transmit data as packets between computers  
over the network. While IP takes care of the actual packet delivery, TCP  
keeps track of the individual packets that the communication (e.g.  
requested a web page file) is divided into, and, when all packets have  
arrived at their destination, it reassembles them to re-form the complete  
file.  
RTSP can be considered a "remote control" for controlling the media  
stream delivered by a media server. RTSP servers typically use RTP as  
the protocol for the actual transport of audio/video data.  
Router - A device that determines the next network point to which a  
packet should be forwarded on its way to its final destination. A router  
creates and/or maintains a special routing table that stores information  
on how best to reach certain destinations. A router is sometimes  
included as part of a network switch. See also switch.  
TCP is a connection-oriented protocol, which means that a connection is  
established between the two end-points and is maintained until the data  
has been successfully exchanged between the communicating  
applications.  
Server - In general, a server is a computer program that provides  
services to other computer programs in the same or other computers. A  
computer running a server program is also frequently referred to as a  
server. In practice, the server may contain any number of server and  
client programs. A web server is the computer program that supplies the  
requested HTML pages or files to the client (browser).  
Telnet - Telnet is a simple method with which to access another  
network device, e.g. a computer. The HTTP protocol and the FTP  
protocols allow you to request specific files from remote computers, but  
do not allow you logon as a user of that computer. With Telnet, you log  
on as a regular user with whatever privileges you may have been  
granted for specific applications and data residing on that computer.  
Sharpness - This is the control of fine detail within a picture. This  
feature was originally introduced into color TV sets that used notch filter  
decoders. This filter took away all high frequency detail in the black and  
white region of the picture. The sharpness control attempted to put some  
of that detail back in the picture. Sharpness controls are mostly  
superfluous in today's high-end TVs. The only logical requirement for it  
nowadays is on a VHS machine.  
TVL (TV Lines) - A method of defining resolutions in analog video.  
UDP (User Datagram Protocol) - UDP is a communications protocol  
that offers limited service for exchanging data in a network that uses  
the Internet Protocol (IP). UDP is an alternative to the Transmission  
Control Protocol (TCP). The advantage of UDP is that it is not required to  
deliver all data and may drop network packets when there is, e.g.  
network congestion. This is suitable for live video, as there is no point in  
re-transmitting old information that will not be displayed anyway.  
Simplex - In Simplex operation, a network cable or communications  
channel can only send information in one direction.  
SMTP (Simple Mail Transfer Protocol) - SMTP is used for sending and  
receiving e-mail. However, as it is "simple," it is limited in its ability to  
queue messages at the receiving end, and is usually used with one of two  
other protocols, POP3 or IMAP. These other protocols allow the user to  
save messages in a server mailbox and download them periodically from  
the server.  
Unicast - Communication between a single sender and a single receiver  
over a network. A new connection is established for each new user.  
URL (Uniform Resource Locator) - An "address" on the network.  
USB - (Universal Serial Bus) A plug-and-play interface between a  
computer and peripheral devices, e.g. scanners, printers, etc.  
SMTP authentication is an extension of SMTP, whereby the client is  
required to log into the mail server before or during the sending of  
email. It can be used to allow legitimate users to send email while  
denying the service to unauthorized users, such as spammers.  
Varifocal lens - A varifocal lens provides a wide range of focal lengths,  
as opposed to a lens with a fixed focal length, which only provides one.  
VAPIX - AXIS VAPIX is considered to be the global application  
programming interface (API) standard, in the rapidly growing field of  
Network Video based on IP.  
AXIS COMMUNICATIONS

SNMP (Simple Network Management Protocol) - SNMP forms part of  
the Internet Protocol suite, as defined by the Internet Engineering Task  
Force. The protocol can support monitoring of network-attached devices  
for any conditions that warrant administrative attention.  
VPN (Virtual Private Network) - This creates a secure "tunnel"  
between the points within the VPN. Only devices with the correct "key"  
will be able to work within the VPN. The VPN network can be within a  
company LAN (Local Area Network), but different sites can also be  
connected over the Internet in a secure way. One common use for VPN  
is for connecting a remote computer to the corporate network, via e.g. a  
direct phone line or via the Internet.  
Sockets - Sockets are a method for communication between a client  
program and a server program over a network. A socket is defined as  
"the endpoint in a connection." Sockets are created and used with a set  
of programming requests or "function calls" sometimes called the  
sockets application programming interface (API).  
VOP (Video Object Plane) - A VOP is an image frame in an MPEG-4  
SSL/TLS (Secure Socket Layer/Transport Layer Security)  
video stream. There are several types of VOP:  
These two protocols (SSL is succeeded by TLS) are cryptographic  
protocols that provide secure communication on a network. SSL is  
commonly used over HTTP to form HTTPS, as used, e.g. on the Internet  
for electronic financial transactions. SSL uses public key certificates to  
verify the identity of the server.  
- An I-VOP is complete image frame.  
- A P-VOP codes the differences between images, as long as it is more  
efficient to do so. Otherwise it codes the whole image, which may also  
be a completely new image.

WAN (Wide-Area-Network) - Similar to a LAN, but on a larger  
geographical scale.  
W-LAN (Wireless LAN) - A wireless LAN is a wireless local area  
network that uses radio waves as its carrier: where the network  
connections for end-users are wireless. The main network structure  
usually uses cables.  
Web server - A Web server is a program, which allows Web browsers  
to retrieve files from computers connected to the Internet. The Web  
server listens for requests from Web browsers and upon receiving a  
request for a file sends it back to the browser.  
The primary function of a Web server is to serve pages to other remote  
computers; consequently, it needs to be installed on a computer that is  
permanently connected to the Internet. It also controls access to the  
server whilst monitoring and logging server access statistics.  
WEP (Wireless Equivalent Privacy) - A wireless security protocol,  
specified in the IEEE 802.11 standard, which is designed to provide a  
wireless local area network (WLAN) with a level of security and privacy  
comparable to that usually expected of a wired LAN. Security is at two  
different levels; 40-bit and 128-bit encryption. The higher the bit  
number, the more secure the encryption.  
WINS (Windows Internet Naming Service) - Part of the Microsoft  
Windows NT Server, WINS manages the association of workstation  
names and locations with IP addresses, without the user or administrator  
having to be involved in each configuration change.  
WPA-PSK (Wi-Fi Protected Access - Pre-Shared Key) - This wireless  
encryption method uses a pre-shared key (PSK) for key management.  
Keys can usually be entered as manual hex values, as hexadecimal  
characters, or as a Passphrase. WPA-PSK provides a greater degree of  
security than WEP.  
Zoom lens - A zoom lens can be moved (zoomed) to enlarge the view of  
an object to show more detail.
