Product Features  
The AXIS 221 is part of the latest generation of fully featured Axis Network Cameras,  
based on the AXIS ARTPEC-2 compression chip. It features a DC-Iris and supports Power  
over Ethernet. It also features a metal casing and an infrared (IR) filter for day and night  
operation.  
Video from the camera is made available on the network as a real-time, full frame rate  
Motion JPEG stream and/or MPEG-4 video stream. The camera includes Video Motion  
Detection, which can be used to trigger e.g. image uploads when there is activity in the  
video image. Uploads can also be scheduled to run at specified times. Security features  
include IP address filtering, encrypted browsing with HTTPS and multilevel password  
protection.  
The AXIS 221 is equipped with two alarm inputs and one output, which can be connected  
to various external devices, e.g. door sensors and alarm bells.  
Video can be viewed in various different resolutions. Up to 20 viewers can access the AXIS  
221 simultaneously when using Motion JPEG and MPEG-4 unicast. The number of  
simultaneous viewers can be increased by using multicast MPEG-4.  
Each MPEG-4 viewer requires a separate MPEG-4 decoder license, of which one is  
included. Additional licenses can be purchased separately from your Axis dealer. If using  
other clients to view the MPEG-4 video stream, no further MPEG-4 decoder licenses are  
required.  
The camera has a built-in Web server, providing full access to all features through the use  
of a standard web browser. The built-in scripting tool allows the creation of basic  
applications. For advanced functionality, the camera can be accessed via the AXIS HTTP  
API (more info at www.axis.com/developer).

AXIS 221 - Video Streams  
12  
Video Streams  
The AXIS 221 provides several different image and video formats. The type to use depends  
on your requirements and on the properties of your network.  
The Live View page in the AXIS 221 provides access to Motion JPEG and MPEG-4 video  
streams, as well as to single JPEG images. Other applications and clients can also access  
these video streams/images directly, without going via the Live View page.  
Video stream types  
Motion JPEG  
This format uses standard JPEG still images in 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 also provides  
excellent image quality and access to each and every individual image contained in the  
stream.  
Note also that multiple clients accessing Motion JPEG streams can use different image  
settings.  
MPEG-4  
This is a video compression standard that makes good use of bandwidth, and which can  
provide high-quality video streams at less than 1 Mbit/s.  
The MPEG-4 standard provides scope for a large range of different coding tools for use by  
various applications in different situations, and the AXIS 221 provides certain subsets of  
these tools. These are represented as Video object types, which are selected for use with  
different viewing clients. The supported video object types are:  
• Simple - sets the coding type to H.263, as used by e.g. QuickTime™.  
• Advanced Simple - sets the coding type to MPEG-4 Part 2, as used by AMC (AXIS  
Media Control)  
When using MPEG-4 it is also possible to control the bit rate, which in turn allows the  
amount of bandwidth usage to be controlled. CBR (Constant Bit Rate) is used to achieve a  
specific bit rate by varying the quality of the MPEG-4 stream. When using VBR (Variable  
Bit Rate), the quality of the video stream is kept as constant as possible, at the cost of a  
varying bit rate.  
Notes: •MPEG-4 is licensed technology. The AXIS 221includes one viewing client license. Installing  
additional unlicensed copies of the viewing client is prohibited. To purchase additional licenses,  
contact your Axis reseller.  
•All clients viewing the MPEG-4 stream must use the same set of coding tools.

MPEG-4 protocols and communication methods  
To deliver live streaming video over IP networks, various combinations of transport  
protocols and broadcast methods are employed.  
• RTP (Realtime Transport Protocol) is a protocol that allows programs to manage the  
real-time transmission of multimedia data, via unicast or multicast.  
• RTSP (Real Time Streaming Protocol) serves as a control protocol, to negotiate which  
transport protocol to use for the stream. RTSP is thus used by a viewing client to start a  
unicast session, see below.  
• UDP (User Datagram Protocol) is a communications protocol that offers limited service  
for exchanging data in a network that uses the Internet Protocol (IP). UDP is an alterna-  
tive 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.  
• Unicasting is communication between a single sender and a single receiver over a net-  
work. This means that the video stream goes independently to each user, and each user  
gets their own stream. A benefit of unicasting is that if one stream fails, it only affects  
one user.  
• Multicast is bandwidth-conserving technology that reduces bandwidth usage by simul-  
taneously delivering a single stream of information to multiple network recipients. This  
technology is used primarily on delimited networks (intranets), as each user needs an  
uninterrupted data flow and should not rely on network routers.  
How to stream MPEG-4  
Deciding on the combination of protocols and methods to use depends on your viewing  
requirements, and on the properties of your network. Setting the preferred method(s) is  
done in the control applet for AMC, which is found in the Windows Control Panel. When  
this has been set, AMC will test all the selected methods in the specified order, until the  
first functioning one is found.  
RTP+RTSP  
This method (actually RTP over UDP and RTSP over TCP) should be your first consideration  
for live video, especially when it is important to always have an up-to-date video stream,  
even if some images are lost due to network problems. This can be configured as multicast  
or unicast.  
Multicasting provides the most efficient usage of bandwidth, especially when there are  
large numbers of clients viewing simultaneously. 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.

AXIS 221 - Video Streams  
14  
Unicasting should be used for video-on-demand broadcasting, so that there is no video  
traffic on the network until a client connects and requests the stream. However, as more  
and more unicast clients connect, the traffic on the network will increase and may cause  
congestion. Although there is a maximum of 20 unicast viewers, note that all multicast  
users combined count as 1 unicast viewer.  
RTP/RTSP  
This unicast method is RTP tunneled over RTSP. This can be used to exploit the fact that it  
is relatively simple to configure firewalls to allow RTSP traffic.  
RTP/RTSP/HTTP or RTP/RTSP/HTTPS  
These two methods can also be used to traverse firewalls. Firewalls are commonly  
configured to allow the HTTP protocol, thus allowing RTP to be tunneled.  
The AXIS Media Control  
The recommended method of accessing live video (MPEG-4 and/or Motion JPEG) from the  
AXIS 221 is to use the AXIS Media Control (AMC) in Microsoft Internet Explorer for  
Windows. This ActiveX component is automatically installed on first use, after which it  
can be configured by opening the AMC Control Panel applet from the Windows Control  
Panel. Alternatively, right-click the video image in Internet Explorer.  
Other methods of accessing the video stream  
Video/images from the AXIS 221 can also be accessed in the following ways:  
• If supported by the client, the AXIS 221 can use Motion JPEG server push to display  
video. This option maintains an open HTTP connection to the browser and sends data as  
and when required, for as long as required.  
• As single JPEG images in a browser. Enter e.g. the path: http://<IP  
address>/axis-cgi/jpg/image.cgi?resolution=320x240  
• Windows Media Player. This requires AMC and the MPEG-4 decoder to be installed. The  
paths that can be used are listed below in the order of preference.  
• Unicast via RTP: axrtpu://<IP address>/mpeg4/media.amp  
• Unicast via RTSP: axrtsp://<IP address>/mpeg4/media.amp  
• Unicast via RTSP, tunneled via HTTP: axrtsphttp://<IP address>/mpeg4/media.amp  
• Unicast via RTSP, tunneled via HTTPS: axrtsphttps://<IP address>/mpeg4/media.amp  
• Multicast: axrtpm://<IP address>/mpeg4/media.amp

AXIS 221 - Video Streams  
15  
Other MPEG-4 clients  
Although it may be possible to use other clients to view the MPEG-4 stream, this is not  
guaranteed by Axis.  
For some other clients, e.g. QuickTime™ the Video Object Type must be set to Simple. It  
may also be necessary to adjust the advanced MPEG-4 settings.  
To assess the video stream from e.g. QuickTime™ the following path can be used:  
rtsp://<IP address>/mpeg4/media.amp  
This path is for all supported methods, and the client will negotiate with the AXIS 221 to  
determine exactly which transport protocol to use.

Video and Image Settings  
The following descriptions show examples of some of the features available in the  
AXIS 221. For details of each setting, please refer to the online help available from the  
setup tools. Click  
to access the online help.  
Image Settings  
Image Appearance  
Adjust these settings to optimize the video images according to your requirements.  
All configuration of images and overlays will affect the camera’s overall performance,  
depending on how it is used and on the available bandwidth. Lower compression improves  
video image quality, but increases the bandwidth.  
Changed video image settings have immediate effect on the MPEG-4 stream, but the  
Motion JPEG stream will have to be started (or restarted) before the settings take effect.  
Text Overlay Settings  
The date, time, and user defined text can be included on one line, either on the top or  
bottom of the video image.  
It is also possible to set how the text and text background are displayed. You can set the  
text to be either black or white, and the text background can also be set to black, white,  
semi-transparent, or transparent.

for further information on these settings.  
Video Stream  
Define the maximum video stream time per session in seconds, minutes or hours. When  
the set time has expired, a new stream can be started by refreshing the page in the Web  
browser. For unlimited video stream time, set this value to 0. This setting is only applicable  
to Motion JPEG.  
The frame rate allowed to each viewer can also be limited, to avoid bandwidth problems  
on the network.  
Test  
To preview the image before saving, click Test. Note that the preview image will be in  
JPEG format, even though the settings are valid both for Motion JPEG and MPEG-4.  
Overlay/Mask  
Settings  
Overlay/Mask Type  
When using an image  
overlay, select from the  
following options the type  
to use:  
Text, date and  
time overlays  
Overlay image  
• Uploaded image as over-  
lay - usually used to pro-  
vide extra information in  
the video image.  
• Uploaded image as pri-  
vacy mask - conceals  
part of the video image.  
• Configurable areas as  
privacy masks - up to 3  
black areas are used to conceal parts of the video image.  
The difference between an overlay and a privacy mask is that a privacy mask cannot be  
bypassed by accessing the video stream with the help of the AXIS HTTP API, whereas an  
overlay can.  
Selecting the overlay/mask type will display further settings available for the selected type.  
See the online help for further information.

Advanced settings  
These web pages include different settings for fine-tuning the video image.  
Camera settings  
To compensate for the Lighting Conditions, the Color level, the Brightness, the  
Sharpness, the Contrast, and the Exposure control, the Exposure area and the IR cut filter  
can all be adjusted. DC-Iris should always be enabled, except when focusing, or when  
using a non-DC-Iris lens.  
The settings for Low Light Behavior determine how the camera will behave at low light  
levels. These settings all affect video image quality and are basically a measure of how  
much noise to allow in the video images.

MPEG-4 Settings  
These are the tools for adjusting the MPEG-4 settings and controlling the video bit rate.  
The MPEG-4 standard provides many different coding tools for various applications in  
different situations. As most MPEG-4 clients do not support all of these tools, it is usual to  
instead define and use subsets for different clients or groups of clients. These settings allow  
you to define the type of viewing client to use.  
Adjusting the maximum bit rate and setting it to variable or constant is a good way of  
controlling the bandwidth used by the MPEG-4 video stream.

Checking the Show viewer toolbar displays the viewer toolbar under the video stream in  
your browser. By checking the Enable MPEG-4 decoder installation box, it is also possible  
for the Administrator to enable or disable the installation of the MPEG-4 decoder. This is  
used to prevent the installation of unlicensed copies. Further decoder licenses can be  
purchased from your Axis dealer.  
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 external source, then select either MPEG-2,  
MPEG-4 or Motion JPEG as the type of video stream to receive.  
Example of a path to an external video source:  
http://192.168.0.125/axis-cgi/mjpeg/video.cgi  
Sequence Mode  
The Live View page can be configured to cycle through the internal and selected external  
video sources, in order, or randomly.  
Select the desired video sources and enter the time in seconds to display each  
source (up to 59 minutes). Click Save.

AXIS 221 - Event Configuration  
27  
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

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 con-  
figured 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. See File Naming & Date/Time Formats  
under Event Configuration in the online help.  
Triggered Event  
A Triggered event can be activated by:  
• a switch (e.g. a push button) connected to the camera’s input port  
• detected movement in a configured motion detection window  
• a manually activated action, e.g. from an action button in the web interface  
• on restart (reboot) after e.g. power loss  
• a temperature warning  
• a camera tampering alarm  
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 min time interval between triggers - The shortest possible interval is 1  
second and the longest is 23 hours, 59 minutes and 59 seconds. (see the online  
help).  
5. Set the Respond to Trigger... parameters for when the event will be active,  
e.g. only after office hours.  
6. Select the trigger alternative from the Triggered by... drop-down list, e.g. select  
Input ports, for the sensor connected to the door.  
7. 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.  
8. Click OK to save the Event in the Event Types list.

AXIS 221 - Event Configuration  
29  
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.  
Configuration example:  
1. Click Add scheduled... on the Event Types page.  
2. Enter a descriptive name for the event, e.g. “Scheduled e-mail upload.”  
3. Set the priority (High, Normal or Low).  
4. Set the Activation Time parameters (24h clock) when the event will be active,  
e.g. start on Sundays at 13.00 with a duration of 12 hours.  
5. Set the When Activated... parameters, i.e. set what the camera will do at the  
specified time, e.g. send uploaded images to an e-mail address.  
6. Click OK to save the Event in the Event Types list.

Please see the online help  
for descriptions of each available option.  
Camera Tampering  
The camera tampering application generates an alarm whenever the camera is  
repositioned, or when the lens is covered, sprayed, or severely defocused.  
You must also create an event, see How to set up a triggered event, on page 28, for the  
camera to send an alarm.  
Settings  
Minimum duration - This parameter sets the minimum tampering period, i.e. an alarm  
will not be triggered until this period has elapsed, even if the tampering conditions are  
otherwise met. This can help prevent false alarms for known conditions that affect the  
image.  
Alarm for dark images - If the camera lens is sprayed or covered so that the camera live  
view becomes dark, it will not be possible to distinguish this situation from other situations  
where the same effect is seen, i.e., when lighting conditions change.  
When this paramater is enabled, alarms will be generated for all cases where the lights are  
either dimmed or turned off, or if the lens is sprayed, covered, or severely defocused. If not  
enabled, no alarm will be sent.  
After making these settings, click Save.

Motion Detection  
Motion detection is used to generate an alarm whenever movement either 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 automatically 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.  
Configuring Motion Detection  
1. Click Motion Detection in the Event Configuration menu.  
2. Click the Configure Included Window radio button.  
3. Click New.

System Options  
Security - Users  
User access control is enabled by default. 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 access levels:  
• Viewer - the lowest level of access, which only allows the user 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. The Operator does not have access to the Systems  
Options configuration pages.  
• Administrator - an administrator has unrestricted access to the Setup Tools and can  
determine the registration of all other users.  
To add a new user, click the Add... button and see the online help.  
User Settings - check the relevant checkboxes to enable:  
• 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.)  
Note: The AXIS 221 keeps a log of all users that access it. See Logs & Reports, on page 44.  
Security - IP Address Filtering  
Checking the Enable IP address filtering box enables the IP address filtering function. Up  
to 256 IP address entries may be specified (a single entry can contain multiple IP  
addresses). Click the Add button to add new filtered addresses.  
When the IP address filter is enabled, addresses added to the list are set as allowed or  
denied addresses. All other IP addresses not in this list will then 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. 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 filter-  
ing is used, then the allowed referrers are automatically restricted to those allowed IP  
addresses.  
Security - HTTPS  
The AXIS 221 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.

Security - 802.1x  
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. If authentication fails, access is prevented on the port. 802.1x is  
based on EAP (Extensible Authentication Protocol).  
In a 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 Free Radius 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 pre-configured port.

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  
pre-configured port.  
RADIUS  
RADIUS (Remote Authentication Dial In User Service) is an 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, and thus acts 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.

Network - Basic TCP/IP Settings  
IP Address Configuration  
The AXIS 221 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 can be set automatically via DHCP, or a static IP address  
can be set manually.  
If IPv6 is enabled, your camera 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: • To receive notification whenever the camera’s IP address changes (via e.g. DHCP), configure the options for  
notification of IP address change. See Services below.  
• If your DHCP server can update a DNS server, you can access the AXIS 221 by host name which is always the  
same, regardless of the IP address.

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.  
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  
221. 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.  
• Primary DNS server - enter the IP address of the primary DNS server.  
• Secondary DNS server - will be used if the primary DNS server is unavailable.

AXIS 221 - System Options  
39  
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.  
Host Name Configuration  
The AXIS 221 can be accessed using a host name, instead of an IP address. The host name  
is usually the same as the assigned DNS Name. It is always the first part of a Fully  
Qualified Domain Name and is always one word, with no period. For example, myserver is  
the host name in the Fully Qualified Domain Name myserver.mycompany.com.  
Enabling dynamic DNS updates allows you to alias a dynamic IP address to a static host  
name, allowing your computer to be more easily accessed from various locations on the  
Internet. Outside users can always access your server using the associated DNS name  
regardless of the WAN IP. The DNS server used by the user and/or the DNS server  
responsible for the domain in use must support RFC2136 and allow updates from the  
camera.  
The TTL (Time To Live) value determines how long (in seconds) the reply from the DNS  
server should be remembered when checking that the domain name for the registered IP  
address is still valid.  
Link-Local IPv4 Address  
Link-Local Address is enabled by default and assigns the AXIS 221 with an additional IP  
address for the UPnP protocol. The AXIS 221 can have both a Link-Local IP and a  
static/DHCP IP address at the same time - these will not affect each other. See Network -  
UPnP™, on page 42.  
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 port mapping.  
HTTPS  
The default HTTPS port number (443) can be changed to any port within the range  
1024-65535. HTTPS is used to provide encrypted web browsing.  
NAT Traversal  
Use NAT traversal when your AXIS 221 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 network camera.  
Enable/Disable - When enabled, the AXIS 221 will attempt to configure port mapping in a  
NAT router on your network, using UPnP™.  
Use manually selected NAT router - Select this option to manually select a NAT router.  
Enter the IP address for the router in the field provided.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
AXIS 221 - System Options  
40  
If a router is not manually specified, the AXIS 221 will automatically search for NAT  
routers on your network. If more than one router is found, the default router, specified in  
System Options > Network > TCP/IP > Basic > IPv4 Address Configuration > 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.  
FTP  
The FTP server running in the AXIS 221 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. Enter the RTSP  
port number to use. The default setting is 554.  
Network Traffic  
Connection type - The default setting is Auto-Negotiate, i.e. the correct speed is  
automatically selected. If necessary, the connection speed can be set by selecting it from  
the drop-down list.  
Maximum bandwidth - Specify, in Mbit/s or kbit/s, the maximum bandwidth that the  
camera is allowed to use on the network. This is a useful function when connecting the  
camera to busy or heavily loaded networks. The default setting is Unlimited.  
Note: When using MPEG-4 as the video format, remember that setting a maximum bandwidth value here may  
create problems for individual video streams if the maximum value is less than the sum of the bit rates set  
for the video streams.  
For more information, please see the online help  
.
Network - SOCKS  
SOCKS is a network proxy protocol. The camera 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 camera 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).

Network - 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 band-  
width 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  
following types of traffic are marked:  
• live video  
• event/alarm traffic  
• management network traffic  
It is important to remember that to be able to use QoS, your network must be properly  
configured. If you are unsure as to whether your network is QoS aware, please check with  
your network administrator.  
QoS 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 form, but saved values  
are always shown in decimal.

AXIS 221 - Troubleshooting  
Troubleshooting  
Checking the Firmware  
50  
Firmware is software that determines the functionality of the AXIS 221. 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 AXIS 221 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 should be saved when the firmware is upgraded (providing the fea-  
tures 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: •If you suspect the firmware upgrade for the AXIS 221 has failed, always wait at least 5-10 min-  
utes before restarting the upgrade process.  
•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.

AXIS 221 - Troubleshooting  
51  
Emergency Recovery Procedure  
If power to the AXIS 221 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 AXIS 221> <Serial number> temp  
ping -s 408 <IP address of camera>  
Windows - From a command/DOS prompt, type the following:  
arp -s <IP address of AXIS 221> <Serial number>  
ping -l 408 -t <IP address of camera>  
2. If the unit does not reply within a few seconds, restart it and wait for a reply. Press  
CTRL+C to stop Ping.  
3. 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. axis221.bin. Then click the Load  
button to restart the upgrade process.  
4. 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.  
5. Reinstall the AXIS 221.  
6. Windows - From a command/DOS prompt, type the following if you are using a DHCP  
server:  
arp -d <IP address of AXIS 221>  
If the emergency recovery procedure does not get the camera up and running again, please  
contact Axis support at www.axis.com/techsup/

AXIS 221 - Troubleshooting  
52  
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 AXIS 221 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 AXIS 221 from the network. Run the Ping command. (In a Com-  
device.  
mand/DOS 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 AXIS 221 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 AXIS 221 cannot be accessed from a Web browser  
The IP address has been changed by  
DHCP.  
1) Move the AXIS 221 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.  
When HTTPS is enabled, ensure that the correct protocol (HTTP or HTTPS) is used when  
attempting to log in. You may need to manually 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 AXIS 221 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.

Check the video image settings. See the online help on Video and Image Settings.  
This can occur when trying to use a larger image buffer than is actually available. Try  
lowering the frame rate or the upload period.  
Slow image update.  
Poor performance.  
Configuring, e.g. pre-buffers, motion detection, high-resolution images, high frame  
rates, etc, will reduce the performance of the camera.  
Poor performance may be caused by e.g. heavy network traffic, multiple users accessing  
the unit, low performance clients, use of features such as Motion Detection, Event han-  
dling, Image rotation other than 180 degrees.  
Image gradually gets darker or lighter. When using the AXIS 221 in locations lit by fluorescent lighting, check in the advanced  
image settings that the Exposure control is set to Flicker-free.  
Image loses focus often.  
Disable the DC-Iris lens in the settings for Video & Image > Advanced. Focus the cam-  
era following the instructions on page 9, and then enable the DC-Iris lens.  
Images only shown in black & white.  
Check the color level setting.  
Check the setting for the IR cut filter. Images are shown in color only when this filter is  
enabled, i.e. when set to yes or auto.  
Blurred images.  
Refocus the camera. Check in the Video & Image > Advanced - Camera Settings that  
DC-Iris is set to Enabled. If the images are still blurred adjust the metal ring until the  
image is sharp, see Removing and attaching the lens, on page 55.  
Rolling dark bands or flickering in  
image.  
Try adjusting the Flicker-free exposure setting under advanced image settings. Note  
that the 'Hold Current'/Manual setting may cause unwanted effects.  
Video/image problems - MPEG-4  
Lower frame rate than expected.  
Check with the administrator that there is enough bandwidth available. Check also the  
settings for bit rate control, in the Video & Image > Advanced > MPEG-4 settings.  
Using an inappropriate video object type can also affect the frame rate. See the online  
help for more information.  
Check in the AMC control panel applet (MPEG-4 tab) that video processing is not set to  
Decode only I frames.  
Lower the image resolution.

AXIS 221 - Replacing the lens  
55  
Replacing the lens  
If the lens on the AXIS 221 needs to be replaced or if the camera was supplied without a  
lens, a new lens can be fitted quickly and easily. As the AXIS 221 is designed with a  
CS-mount, the lens supplied with your product can be replaced with any standard C or CS  
lens.  
Note: Although the lens supplied with your product can be directly replaced with any CS-type lens, a C-type lens must  
be installed with an adapter for it to work with your AXIS 221. An adapter effectively moves the lens 5mm  
farther from the camera.  
Removing and attaching the lens  
1. Disconnect the power supply to the AXIS 221.  
Zoom puller  
(Tele/wide)  
Metal ring  
2. Disconnect the DC-Iris cable.  
3. Unscrew the lens by turning it  
anti-clockwise.  
Focus puller  
4. Screw on the new lens until it is tight  
against the metal ring at the back.  
5. Attach the DC-Iris cable to the camera  
and reconnect the power supply.  
6. To focus the new lens, see Focusing, on  
DC-Iris control cable  
page 9.  
Note: In the unlikely case that the camera images are still blurred after focusing the lens, loosen the screw on the  
underside of the camera that holds the metal ring in place. Turn the metal ring in small increments until a  
sharp image is obtained. Tighten the screw on the underside of the camera.

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. Band-  
width affected.  
• Simultaneous viewing of different streams (resolution, compression, etc.) by dif-  
ferent 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 is affected.  
• Viewing on poorly performing client PC’s lowers perceived performance. Frame  
rate affected.  
Optimizing your system  
To see the bandwidth and frame rate currenty required by the video stream, the AXIS 221  
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.  
Important!  
•The figures displayed here are the values as delivered by the camera. If other restrictions are  
currently in force, (e.g. bandwidth limitation) these values might not correspond to those actu-  
ally received by the client.  
•For Motion JPEG, these values will only be accurate as long as no frame rate limit has been  
specified.

• Video Object Type = Advanced Simple  
• GOV length = 8  
• GOV structure = IP*  
*Note that setting the GOV structure to use “I-frames only” will increase the frame rate at the expense of  
the bit rate.  
Bandwidth  
As there are many factors that affect bandwidth, it is very difficult to predict the required  
amounts. The settings that affect bandwidth are:  
• the image resolution  
• the image compression  
• the frame rate  
• the MPEG-4 object type  
• the MPEG-4 GOV structure  
• the maximum exposure time.  
There are also factors in the monitored scene that will affect the bandwidth. These are:  
• the amount of motion  
• the image’s complexity  
• the lighting conditions.  
For MPEG-4, if there is only limited bandwidth available, and if this is more important  
than the image quality, using a constant bit rate (CBR) is recommended. Use a variable bit  
rate (VBR) if the image quality needs to be maintained at a higher level. If supported on the  
network, consider also using MPEG-4 multicasting, as the bandwidth consumption will be  
much lower.

exchanging files (text, images, sound, video, and other files) on  
the World Wide Web.  
HTTPS - Hypertext Transfer Protocol over Secure Socket Layer.  
A web protocol that provides encryption for page requests from  
users and for the pages returned by the web server.  
AMC - AXIS Media Control. The control required for  
viewing video images in Internet Explorer. Installs  
automatically on first use.

API - Application Programming Interface. The Axis API  
can be used for integrating Axis products into other  
applications.  
IP address - A unique number used by a network device, to  
allow it to be identified and found on the network. The 32-bit  
IP address is made up of four groups (or quads) of decimal  
digits separated by periods. An example of an IP address is:  
192.168.0.1  
ARP - Address Resolution Protocol. A protocol used to  
associate an IP address to a hardware MAC address. A  
request is broadcast on the local network to find out what  
the MAC address is for the IP address.  
ISMA - Internet Streaming Media Alliance.  
ARTPEC - Axis Real Time Picture Encoder - used for video  
image compression.  
JPEG - A standard image format, used widely for photographs.  
Also known as JPG.  
CCD - Charge Coupled Device. CCD is one of the two main  
types of image sensors used in digital cameras. When a  
picture is taken, the CCD is struck by light coming through  
the camera’s lens. Each of the thousands or millions of tiny  
pixels that make up the CCD convert this light into  
electrons.  
LAN - A local area network (LAN) is a group of computers and  
associated devices that typically share common resources  
within a limited geographical area.  
Linux - A popular, free, open source, UNIX like operating  
system, developed in cooperation by various individuals and  
organizations.  
CGI - Common Gateway Interface. A set of rules (or a  
program) that allows a Web Server to communicate with  
other programs.  
Lux - A standard unit for the measurement of light, where 1  
Lux equals the light emitted from a single candle at a distance  
of one meter.  
Client/Server - Describes the network relationship between  
two computer programs in which one, the client, makes a  
service request from another - the server.  
Mbit/s - Megabits per second. A unit for measuring speeds in  
networks. A LAN might run at 10 or 100 Mbit/s.  
MPEG-4 - A video compression standard that makes good use  
of bandwidth, and which can provide high-quality video  
streams at less than 1 Mbit/s.  
DC-Iris - This special type of iris is electrically controlled  
by the Axis camera, to automatically regulate the amount  
of light allowed to enter.  
Multicast - A bandwidth-conserving technology that reduces  
bandwidth usage by simultaneously delivering a single stream  
of information to multiple network recipients.  
DNS - The Domain Name System (DNS) locates and  
translates Internet domain names into IP (Internet Protocol)  
addresses.  
NTSC - National Television Standards Committee. NTSC is the  
standard format used for televisions in most of North and  
Central America, and Japan.  
Ethernet - A widely used networking standard.  
ETRAX - A family of microprocessors developed by Axis.  
Firewall - A virtual barrier between a LAN (Local Area  
Network) and other networks, e.g. the Internet.  
NWAY - A network protocol that automatically negotiates the  
highest possible common transmission speed between two  
devices.  
FTP - File Transfer Protocol. Used for the simple transfer of  
files to and from an FTP-server.  
PAL - Phase Altering Line. PAL is the standard format used for  
televisions in most of the world (other than the US, Canada, and  
Japan).  
Full-duplex - Transmission of data, e.g. audio, in two  
directions simultaneously. In an audio system this would  
describe e.g. a telephone system. Half-duplex also provides  
bi-directional communication, but only in one direction at  
a time, as in a walkie-talkie system. See also Simplex.  
PEM - Privacy Enhanced Mail. An early standard for securing  
electronic mail. The PEM-format is often used for representing  
an HTTPS certificate or certificate request.

UPnPTM - Allows the automatic peer-to-peer detection of  
devices on the network.  
Ping - A small utility used for sending data packets to  
network resources to check that they are working and that  
the network is intact.  
62  
URL - Uniform Resource Locator. An “address" on the network.  
Pre/post alarm image - The images from immediately  
before and after an alarm.  
Varifocal - A varifocal lens provides a wide range of focal  
lengths, as opposed to a lens with a fixed focal length, which  
only provides one.  
Privacy mask - An image or specified area used to block  
out certain parts of the video image.  
WAN - Wide-Area-Network. Similar to a LAN, but on a larger  
geographical scale.  
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.  
Web server - A program on a computer (server) providing the  
resources (e.g. web pages) requested by the user (client).  
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 is often included as part of a  
network switch (see below).  
RTP - Real-Time Transfer Protocol. A transfer protocol  
designed for delivery of live contents, e.g. MPEG-4.  
Simplex - In simplex operation, a network cable or  
communications channel can only send information in one  
direction.  
SMTP - Simple Mail Transfer Protocol. A protocol used for  
e-mail transmissions over the Internet.  
SNMP - Simple Network Management Protocol. An  
application layer protocol that facilitates the exchange of  
management information between network devices. It is  
part of the Transmission Control Protocol/Internet Protocol  
(TCP/IP) protocol suite.  
Subnet Mask - An IP address consists of two components:  
the network address and the host address. “Subnetting’  
enables a network administrator to further divide the host  
part of the address into two or more subnets. The subnet  
mask identifies the subnet to which an IP address belongs.  
Switch - Whilst a simple hub transmits all data to all  
devices connected to it, a switch only transmits the data to  
the device it is specifically intended for.  
TCP/IP - Transmission Control Protocol/Internet Protocol.  
A suite of network protocols that determine how data is  
transmitted. TCP/IP is used on many networks, including  
the Internet. TCP keeps track of the individual packets of  
information and IP contains the rules for how the packets  
are actually sent and received.  
UDP - The User Datagram Protocol is a communications  
protocol that offers a limited amount of service when  
messages are exchanged between computers in a network  
that uses the Internet Protocol (IP). UDP is an alternative to  
the Transmission Control Protocol (TCP) and, together with  
IP, is also known as UDP/IP.  
Unicast - Communication that takes place over a network  
between a single sender and a single receiver.
