Product description
Overview
The AXIS 243Q Blade Video Server is a fully featured video server intended for security
surveillance and remote monitoring needs. It is designed for mounting in the AXIS 291
Video Server Rack, which provides power and network connectivity.
DIP switches
Control button
Video inputs 1-4
LED Indicators
The AXIS 243Q Blade video server is a four-in-one solution, which means that each
physical blade unit contains four separate video servers, one for each video input. The
individual video servers display as AXIS 243Q(1) Blade, AXIS 243Q(2) Blade, AXIS 243Q(3)
Blade and AXIS 243Q(4) Blade. The descriptions that follow apply to all four video servers,
except where otherwise indicated. Each input has its own IP address.
The four BNC inputs on AXIS 243Q Blade are for connecting analog video devices. The
video server digitizes up to four analog video sources and makes them available on the
network as real-time, full frame rate MPEG-4 and/or Motion JPEG video streams.
Each video input provides one alarm input and one alarm output that can be used to
connect various third party devices, such as door sensors and alarm bells. The AXIS
243Q(1) Blade provides an RS-485 port for connecting to third-party PTZ systems. PTZ
devices can also be used on AXIS 243Q(2) Blade, AXIS 243Q(3) Blade and AXIS 243Q(4)
Blade, by creating an internal connection to these from AXIS 243Q(1) Blade.

Up to 20 viewers can access each video input on the AXIS 243Q Blade simultaneously
when using Motion JPEG and MPEG-4 unicast. The number of simultaneous viewers can
be increased by using multicast MPEG-4. When using AXIS Media Control (AMC) to view
MPEG-4 video streams, each MPEG-4 viewer requires a separate MPEG-4 decoder license.
One license is included, and further 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.
Video can be viewed in five resolutions (up to 4CIF), and image compression is
configurable. The AXIS 243Q Blade contains support for video motion detection, which
allows the unit to trigger activity in the video image, and advanced scheduling tools which
can also be used to trigger an event. As the AXIS 243Q Blade is designed for use in
security systems, it is equipped with several security features, such as IP address filtering,
user levels with passwords, and HTTPS.
Each video input on the AXIS 243Q Blade 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
basic applications to be created, providing basic surveillance solutions. For advanced
functionality, the video server can be integrated via the use of the VAPIX® API (see

AXIS 243Q Blade - Video streams

Video streams
The AXIS 243Q Blade provides several different video stream formats. You select the type
depending on your requirements and on the properties of your network.
The Live View page in the AXIS 243Q Blade 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 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 243Q Blade 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
control of bandwidth. 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 243Q Blade includes one viewing client license.
Installing additional unlicensed copies of the viewing client is prohibited. To purchase addi-
tional 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 (Real-Time 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 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 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
network. 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
simultaneously 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 do get dropped. 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 the Internet.

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.
AXIS Media Control (AMC)
The recommended method of accessing live video from the AXIS 243Q Blade is to use the
AXIS Media Control (AMC) in Microsoft Internet Explorer in 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 243Q Blade can also be accessed in the following ways:
• If supported by the client, the AXIS 243Q Blade 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 the path:
Note: To specify other parameters refer to the VAPIX® API in the Developer pages at the Axis web site
• 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>/mpeg4/media.amp
• Unicast via RTSP: axrtsp://<ip>/mpeg4/media.amp
• Multicast: axrtpm://<ip>/mpeg4/media.amp
Note: <ip> = IP address.

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, such as, 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 QuickTime™ the following path can be used:
rtsp://<ip>/mpeg4/media.amp
This path is for all supported methods, and the client will negotiate with the AXIS 243Q
Blade to determine exactly which transport protocol to use.

All configuration of images and overlays will affect the performance of the video server,
depending on usage and the available bandwidth.
• High resolution generates larger files
Selecting the Aspect ratio correction option improves the appearance of images
from analog video sources, that are displayed on computer monitors.
When using MPEG-4 as video format, any aspect ratio correction for the image is
applied by the viewing client (the correct aspect ratio is contained in the MPEG-4
stream).
Resolution - 4CIF de-interlacing - Showing interlaced video on a computer
monitor may produce distortion when there is movement in the image. Selecting
this option reduces the distortion.
• Lower compression improves image quality, but generates larger files
• Rotating the image 90 or 270 degrees will lower the maximum frame rate
• Black & White uses less bandwidth than Color
For more information on all these options, please check the online help
.
Text overlay settings
Include date, time and/or text of your choice to be viewed on the image. The color of the
text may be set to white or black, while background color may be set to white, black,
transparent or semitransparent. The position of the text is set either to the top or the
bottom of the image.
Video stream
The Maximum video stream time can be set as Unlimited, or set a maximum stream time
per session in seconds, minutes or hours. When the set time has expired, a new stream on
the Live View page can be started by refreshing the page in the web browser. Note that the
maximum video stream time does not apply to clients connecting via multicast.
To avoid bandwidth problems on the network, the frame rate allowed to each viewer can
also be limited. Select either Unlimited or define a maximum frame rate per viewer.

Video source settings
These settings allow you to eliminate black borders surrounding the image, by making
Offset adjustments. By entering values in these fields you can change the horizontal and
vertical synchronization for the image. See the online help
for more information.
Advanced - MPEG-4 settings
These are tools for adjusting the MPEG-4 settings and for 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 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 client to use.
Under Client Compatibility, select the correct combination of Video object type with the
ISMA compliant option to use for your viewing client.
The GOV Settings describe the composition of the MPEG-4 video stream and this format's
basic elements.
The GOV Structure can take two different forms; I or IP, which describe the type of images
included in the video stream, as well as their internal order.
The GOV Length determines how many images of the one type (I or P) are sent before the
next type is sent.

Adjusting the Maximum bit rate and setting it to Variable or Constant helps control the
bandwidth used by the MPEG-4 video stream.
Bit Rate control
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.
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, and thus uses a lot of
bandwidth for a lot of activity in the image and less when the monitored area is quiet.
When using CBR you can set a fixed Target bit rate, which will ensure that the level of
bandwidth consumed is predictable and will not change, whatever happens in the image.
Priority - As the bit rate would usually need to increase for increased image activity, but
cannot when CBR is selected, the frame rate and image quality will both 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.
Video Stream
This parameter can be set to frame rate to increase the frame rate by 30% in 4CIF
resolution. This means that under normal conditions the maximum frame rate can be
increased from 17 fps to 22 fps in PAL, and from 21 fps to 27 fps in NTSC.
Note also that depending on the amount of motion, this may also increase the required
bandwidth by 1-15% for each frame.
This parameter has no effect when the resolution is set to lower than 4CIF, although there
is a risk of increased bandwidth usage. In this case the parameter should be set to
bandwidth.

.

Advanced - MJPEG settings
Sometimes the image size may be large due to low light or complex scenery. Adjusting the
Maximum frame size is a good way of controlling the bandwidth and storage used by the
MJPEG video stream in these situations. Defining the frame size as Unlimited will provide
consistently good image quality at the expense of increased bandwidth and storage usage
during low light. Limiting the frame size helps optimize bandwidth and storage usage, but
gives poor image quality. To prevent increased bandwidth and storage usage, the
maximum frame size should be set to an optimal amount.
Overlay/Mask

When using an image overlay,
select the Overlay/Mask Type from
the following options:
• Uploaded image as overlay -
usually used to provide extra
information in the video image.
• Configurable areas as privacy
masks - up to three 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.
Upload and use an overlay image
1. Select Uploaded image as overlay in the Overlay/Mask Type drop-down list.
New options appear.

Overlay image limitations:
• The maximum overlay image size supported by the AXIS 243Q Blade is the same
• When a text overlay is also used, this reduces the amount of space available to
the overlay image. To keep the text readable at lower resolutions, the text overlay
occupies proportionally more of the image at lower resolutions.
• If the overlay is initially positioned so that part of it is outside the video image, it
will be relocated so that it appears over the video image, that is, it is always the
entire image that is displayed.

PTZ controls
If the AXIS 243Q Blade has been appropriately configured, the Live View page displays the
controls available for the installed Pan Tilt Zoom (PTZ) device. The administrator can
enable/disable the controls for specified users.
Tilt bar (relative)
The exact controls shown depends on the make and model of PTZ device. The most
common controls are:
• the Pan bar - moves the camera to the right and left
• the Tilt bar - tips the camera up and down
• the Zoom bar - zooms the view in and out. Note that this is only available if the
camera is fitted with a zoom lens.
• the Iris bar - adjusts the brightness of the image.
Clicking on the bars themselves or on the arrows at the end of the bars will move the
camera to a new position. The type of movement and the location of this new position
depends on the type of PTZ driver.
When controlling the camera using a relative PTZ driver (see the bars in the illustration
above) the new position is relative to the previous position, that is, left of, below, above,
and so on. Clicking the bar further from the center results in a larger movement.

In contrast, when using an absolute driver, each
position on the bar (see right) represents a defined
position in the device’s range of movement, with the center of the bar representing the
point midway between the two extremes of movement.
Clicking a position directly on the bar moves the camera directly to the new position in
one smooth movement. Clicking on the arrows at the ends of a bar causes a stepped,
incremental change.
Using CGI links to control PTZ devices
User-defined CGI links on the Live View page help issue HTTP API requests, for example,
PTZ control modes
The PTZ device can also be controlled using click-in-image movement, which has two
types of navigation - Center and Joystick.
The Center mode means that when clicking in the image, the camera view will center on
the absolute position that was clicked.
The Joystick mode moves the camera in the direction of the mouse pointer. By clicking
and holding the mouse button down in the image, the PTZ device moves the camera in that
direction, relative to the center of the image. The further from the center the image is
clicked, the greater the movement. The camera stops moving when the button is released.
Note: There is also joystick support in AXIS Media Control (AMC).
Control panel
The focus and iris (image brightness) can be adjusted manually by using the control bars,
or they can be set for automatic adjustment, by clicking the Auto iris and Auto focus
buttons.
Note: These buttons appear only if the PTZ driver installed supports them.
To access the Auto iris and Auto focus buttons, click the Control
panel button. The menu to the right will then appear in the upper left
hand corner of the screen.
There are also driver specific shortcuts that can appear in the Control
Panel. In the screen to the right, a driver has been installed that
brings up the Wiper shortcut button, which allows the user to
configure and use a windshield wiping action with the AXIS 243Q
Blade.

currently first in queue. The administrator will be removed from the queue 60
seconds after their last PTZ control command.
2. Event - The AXIS 243Q Blade can be set up to take control of the queue and
move to a specific position for 20 seconds when triggered by an alarm. The event
will immediately be placed first in the queue, except when an administrator is in
3. Operator - Same as administrator, but with lower priority.
4. Guard Tour - A guard tour has PTZ control for an indefinite period of time. It
may be overridden by; Operator, Event or administrator. Guard Tour will resume
when higher priority groups leave the queue. For more information see Guard
5. Viewer - Multiple viewers must wait for their turn. The viewer has 60 seconds
PTZ control before control is passed to the next viewer in queue.
Note: In order to identify different users in the viewer group, cookies must be enabled on the client.
Using PTZ on video inputs 2-4
Although the AXIS 243Q Blade supports an RS-485 port on video input 1 only, it is still
possible to use PTZ devices on video inputs 2-4 by creating virtual connections to these
1. Configure PTZ on video input 1 and install the required PTZ driver. This step is
always required, whichever video input you intend to use for PTZ, and is
2. Repeat this procedure and install the same device driver on the other video
input(s) you wish to use PTZ on.
3. Enter the same Authentication key as configured for video input 1. This will
prevent unauthorized access to the RS-485 port.
PTZ devices on inputs 2-4 are configured in the same way as a device on video input 1.

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 in the list are defined as allowed or denied
addresses. Other IP addresses not in this list will be allowed or denied access accordingly; if
the addresses in the list are allowed, then others are denied access, and vice versa. See also
the online help
for more information. Users from IP addresses that are allowed must
also be registered with the appropriate access rights (User, Operator or Administrator).
This is done from Setup > System Options > Security > Users.
Referrals - to prevent unauthorized sources including the video stream from the AXIS
243Q Blade into external Web pages, check the Referrals option and enter the IP address or
Host name of the computer hosting the Web pages with the included video stream.
Multiple IP addresses/host names can be defined and are separated by semicolons (;).
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 fil-
tering 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
For greater security, the AXIS 243Q Blade can be configured to use HTTPS (Hypertext
Transfer Protocol over SSL (Secure Socket Layer)). That is, all communication that would
otherwise go via HTTP will instead go via an encrypted HTTPS connection.
Certificate - to use HTTPS for communication with the AXIS 243Q Blade, a Certificate must
be created using one of these methods:
• A self-signed certificate can be created in the video server, but this does not guar-
antee the same level of security as an official certificate.
• An official certificate issued by a CA (Certificate Authority). A CA issues and
manages security credentials and public keys for message encryption.
To create a certificate:
1. Click either Create self-signed certificate or Create Certificate Request and enter
the required information in the provided fields
2. Click OK.
3. The Create self-signed certificate option generates and installs a certificate that
is displayed under Installed Certificate.
The Create Certificate Request option generates a PEM (Privacy Enhanced Mail)
formatted request which you copy and send to a CA for signing. When the signed
certificate is returned, click Install signed certificate... to install the certificate in
the AXIS 243Q Blade.
4. Set the HTTPS Connection Policy for the administrator, Operator and Viewer to
enable HTTPS connection (set to HTTP by default)
Note: Privacy Enhanced Mail (PEM), is an early IETF proposal for securing email using public key cryptography.
Please refer to the home page of your preferred CA for information on where to send the
request. For more information, please see the online help

IEEE 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, or, if authentication fails, preventing access on that port.
802.1x is based on EAP (Extensible Authentication Protocol). There are many EAP methods
available to access a network protected by 802.1x/EAPOL (Extensible Authentication
Protocol Over Lan). The one used here is EAP-TLS (EAP-Transport Layer Security).
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. 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.
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 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
RADIUS (Remote Authentication Dial In User Service) is an AAA (Authentication,

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 CAs that charge for their services. Institutions and
governments may have their own CA, and there are free CAs available.

Network Settings. Click the View button to see current network settings.
IPv4 and IPv6 Address Configuration
The AXIS 243Q Blade 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: 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 243Q Blade 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.
•
AXIS Internet Dynamic DNS Service - If the AXIS 243Q Blade has been registered with the
Axis Internet Dynamic DNS service and the IP address for the product changes, the service
is updated to reflect the change. Check the box to enable/disable automatic updates.
The domain name currently registered at the Axis Internet Dynamic DNS service for your
product can at any time be removed. To do this click Settings... and follow the

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 243Q
Blade. 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 and Secondary DNS server- enter the IP addresses of the primary and
secondary DNS servers.
NTP configuration
Obtain NTP server address via DHCP - use a DHCP server to automatically find an NTP
server to synchronize clock of the AXIS 243Q Blade with the other devices on the network
Use the following NTP server address - use the host name or IP address of a specific NTP
server for time synchronization.
Host Name Configuration
The AXIS 243Q Blade 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.

HTTP
The default HTTP port number (80) can be changed to any port within the range
1024-65535. This is useful for simple port mapping.
HTTPS
The default HTTPS port number (443) can be changed to any port within the range
1024-65535. This is useful for simple port mapping.
NAT traversal (port mapping) for IPv4
Use NAT traversal when the AXIS 243Q Blade 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.
FTP
The FTP server running in the AXIS 243Q Blade enables the upload of new firmware, user
applications, and so on. Check this box option to enable the service.
RTSP
The RTSP protocol allows a connecting client to start an MPEG-4 stream. Check the box to
enable the RTSP server and enter the RTSP port number to use. The default setting is 554,
and the allowed port range is 1024-65535. Note that MPEG-4 streams will not be available
if this is not enabled.
Network traffic
Connection type - The default setting is Auto-negotiate, that is, 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.

SOCKS
SOCKS is a networking proxy protocol. The AXIS 243Q Blade 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 video server 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 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.
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 hex form, but saved values are always
shown in decimal.

SNMP
The Simple Network Management Protocol (SNMP) allows the remote management of
network devices. Select the version of SNMP to use, depending on the level of security
required. Select the version of SNMP to use, by checking the appropriate box. The three
levels of security are:
• SNMP V1 - includes no security
• SNMP V2c - uses very simple security, e.g. community name as password
• SNMP V3 - provides encryption and secure passwords. Use with HTTPS.
If using V1 and V2c, enter the community name for read-only access to all supported
SNMP objects (except the root password and other objects that require write access).
Default value = public. You can also specify the community name for read/write access to
all supported SNMP objects (except read-only objects). Default value = pass.
If using HTTPS enter the password if it has not already been set. To set the password again,
the AXIS 243Q Blade must be reset to the factory default settings.

• Pan Tilt Zoom (PTZ) - for controlling a PTZ device. A PTZ device requires a driver
for information on how to connect PTZ devices.
While the RS-485 can be used to connect a PTZ device, it is necessary that the device’s
protocol supports ‘daisy chaining’ in order to connect and control more than one camera
(up to four).
Chaining the units allows them to share a single serial port. The protocol then decides
which unit to address and sends commands to it specifically. The diagram below explains
how the devices are connected.

Problems uploading own files
Missing images in uploads
Slow image update
There is only limited space available for the upload of your own files. Try deleting one or more
existing files, to free up space.
This can occur when trying to use a larger image buffer than is actually available. Try lowering
the frame rate or the upload period.
Configuring pre-buffers, motion detection, high resolution images, and high frame rates, will
reduce the performance of the video server.
Slow performance
Slow performance may be caused by heavy network traffic, multiple users accessing the unit,
low performance clients, and features such as Motion Detection, Event handling, Image rota-
tion.
Bad snapshot images

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 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 lowers perceived performance. Frame
rate affected.
Optimizing your system
To see the bandwidth and frame rate currently required by the video stream, the AXIS
243Q Blade 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 server. If other restrictions are
currently in force, (e.g. bandwidth limitation) these values might not correspond to those
actually received by the client.
•For Motion JPEG, these values will only be accurate as long as no frame rate limit has been
specified.

Bandwidth
As there are many factors affecting 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 analog cameras connected to the video server
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.

computer monitors is 4:3. High-definition television
(HDTV) uses an aspect ratio of 9:16.
Glossary
Autoiris (DC-Iris) - This special type of iris is electrically
controlled by the camera, to automatically regulate the
amount of light allowed to enter.
ActiveX - ActiveX is 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.
AVI (Audio Video Interleave) - A video format that
supports simultaneous playback of audio and video.
AXIS Internet Dynamic DNS Service - This free service
provides an Axis network product with a unique DNS or
domain name (URL address), which can then be used
instead of an IP address to access the product from a web
browser.
AF (Autofocus) - A system by which the camera lens
automatically focuses on a selected part of the subject.
AMC (AXIS Media Control) - AMC is the ActiveX
component required to view moving images from an Axis
video device in Internet Explorer. The component is
installed automatically on the viewing computer on first
use. Once installed, AMC can be configured from
Windows Control Panel.
AXIS IP Utility - A tool for discovering and setting IP
addresses for Axis network devices. AXIS IP Utility is
supplied free of charge by Axis.
AXIS Camera Management - A powerful and efficient
installation and management tool for Axis network video
products. The tool can automatically find and set IP
addresses, show connection status and manage firmware
upgrades of multiple devices.
Analog video camera - The signal from an analog video
camera is viewed directly on e.g. a monitor in the analog
system, which depends on traditional analog cabling.
Alternatively, the signal can be digitized with the use of a
video server, and can then be made available over a data
(IP) network.
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." GIFs and
JPEGs are examples of image file types that contain
bitmaps. 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.
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.
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.
API (Application Programming Interface) - An API is a set
of routines, protocols, and tools for building software
applications. A good API makes it easier to develop a
program by providing all the required building blocks.
The Axis VAPIX API allows Axis products to be
integrated into other applications.
Bonjour - Also known as zero-configuration networking,
Bonjour enables the automatic discovery of computers,
devices, and services on IP networks. Bonjour allows
devices to automatically discover each other without the
need to enter IP addresses or configure DNS servers.
Bonjour is developed by Apple Computer Inc.
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.
BOOTP (Bootstrap Protocol) - A protocol that can
automatically configure a network device (give it an IP
address). BOOTP is the basis for a more advanced network
management protocol, the Dynamic Host Configuration
Protocol (DHCP).
ARTPEC (Axis Real Time Picture Encoder) - A chip
designed by Axis for image compression. ARTPEC
supports a range of CCD and CMOS sensors, built-in
functionality for sharpening, backlight compensation,
noise reduction and white balance, support for multiple
Motion-JPEG streams, support for MPEG-4 part 2, up to
30 frames/second from 4 simultaneous video sources and
real-time compression of up to 45 Megapixels/second.
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".
ASIC (Application Specific Integrated Circuit) - A circuit
designed for a specific application, as opposed to a
general purpose circuit, such as a microprocessor.
CCTV (Closed Circuit Television) - A CCTV system is a
closed/private video system, usually constructed with
coaxial cabling, and used within a single building/group

CCTV video camera - A traditional CCTV video camera is
an analog camera, available in both monochrome (black
and white) and color. Cameras can be set in fixed
positions or placed on "Pan/Tilt/Zoom" devices, which
allow the camera to be maneuvered. Using a zoom lens
provides a closer view of the object being viewed. CCTV
analog video cameras can be viewed over a computer
network by using a video server.
lightest and darkest parts of an image or video stream.
Control unit - If a CCTV system has more than one
camera, there must be a way to control the video signals
going to recorders and monitors. There are three basic
types of Video Control Unit: Multiplexer, Switch and
Quad.
dB (Decibels) - A unit to measure sound level changes. A
3dB change is the smallest level change we can hear. A
3dB change is actually twice or half the audio power
level. A gain of 0dB will leave the signal level unchanged.
CGI (Common Gateway Interface) - A specification for
communication 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.
DC-Iris - This special type of iris is electrically controlled
by the camera, to automatically regulate the amount of
light allowed to enter.
CIF (Common Intermediate Format) - CIF refers to the
analog video resolutions 352x288 pixels (PAL) and
352x240 pixels (NTSC). See also Resolution.
Decoder - See Video decoder.
De-interlacing - See Interlacing.
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.
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.
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.
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.
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
easier to remember than 192.0.34.166. The translation
tables for domain names are contained in Domain name
servers.
Coaxial cable - Coaxial cable is the standard means of
transmitting analog video in a CCTV system. Coaxial is
also used by cable companies to distribute television in
residential buildings.
Domain server - Domains can also be used by
organizations that 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.
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.
Dome network camera - A remotely controllable camera
mounted in a special housing, characterized by the dome
shaped glass or plastic covering behind which the camera
resides. Usually mounted on a ceiling and looking
downwards, a dome camera can often rotate up to 360
degrees, thus providing excellent coverage of large areas.
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.
Composite video - A type of video signal in which the

bi-directional communication, but only in one direction
at a time, as in a walkie-talkie system. See also Simplex.
DVR (Digital Video Recorder) - A DVR records analog
video to a hard disk in digital format. Most DVRs use the
MPEG-2 format for encoding analog video signals.
G.711 - The international standard for encoding
telephone audio on a 64 kbps channel. It is a pulse code
modulation (PCM) scheme operating at 8 kHz sample rate.
Encoder - See Video encoder.
G.726 - A frequently used speech-compression algorithm
in telecommunications due to its high perceived speech
quality and low resource requirements.
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.
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.
ETRAX (Ethernet Token Ring AXIS) - The ETRAX chip is
the cornerstone of Axis technology and the 'brain' in
nearly all Axis products. A multipurpose Linux chip with
integrated Ethernet networking and extremely flexible I/O
options.
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.
Factory default settings - These are the settings that
originally applied 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.
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.
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.
GOV (Group Of VOPs) - A group of VOPs is the basic unit
of an MPEG-4 video stream. The GOV contains different
types and numbers of VOPs (I-VOPs, P-VOPs) as
determined by the GOV length and GOV structure. See
also VOP.
Fixed iris - See Autoiris.
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.
GOV length - The GOV length determines the number of
images (VOPs) in the GOV structure.
See also GOV and VOP.
FTP (File Transfer Protocol) - FTP is an application
protocol that uses the TCP/IP protocols, used to exchange
files between computers/devices on networks.
GOV structure - The GOV structure describes the
composition of an MPEG-4 video stream, as regards the
type of images (I-VOPs or P-VOPs) included in the stream,
and their internal order. See also GOV and VOP.
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.
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.
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.
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.
HTTPS (Hypertext Transfer Protocol over SSL) - HTTPS
is a protocol used by web browsers and servers to encrypt
and decrypt user page requests and the pages returned by
the server. The encrypted exchange of information is
governed by the use of an HTTPS certificate (issued by a
Certificate Authority), which guarantees the authenticity
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

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. See also IP (Internet Protocol).
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.
Inputs/Outputs (I/Os) - The digital I/Os on, for example, a
network camera can be used to connect any device that
can toggle between an open and a closed circuit.
IEEE 802.11 - A family of standards for wireless LANs.
The 802.11a standard supports 1 or 2 Mbit/s transmission
on the 5 GHz band. IEEE 802.11b supports data rates up
to11 Mbit/s on the 2.4 GHz band, while 802.11g allows up
to 54 Mbit/s on the 2.4 GHz band.
For example, if a door switch is used as an input device,
opening the door could trigger the upload of video images
and the sending of notification messages.
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. See also
MPEG and Motion JPEG.
An output might, for example, be used to automatically
start a siren when there is a motion detection trigger.
ISMA (Internet Streaming Media Alliance) - ISMAs goal
is: "To accelerate the adoption and deployment of open
standards for streaming rich media content such as video,
audio, and associated data, over Internet protocols."
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.
I-VOP - See 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.
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.
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.
LAN (Local Area Network) - A LAN is a group of
computers and associated devices that typically share
common resources within a limited geographical area.
Linux - Linux is an open source operating system within
the UNIX family. Because of its robustness and
availability, Linux has won popularity in the open source
community and among commercial application
developers.
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.
Lux - A standard unit of illumination measurement.
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.
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.
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.
Manual iris - This is the opposite of an autoiris, i.e. the
camera iris must be adjusted manually to regulate the
amount of light allowed to reach the image sensor.
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.
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.
Monitor - A monitor is very similar to a television set, but
An IP address consists of four groups (or quads) of

lacks the electronics to pick up regular television signals.
locations to simultaneously access images. A network
camera is sometimes known as an IP camera.
Motion JPEG - Motion JPEG is a simple
compression/decompression technique for network 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.
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.
Network video - Network video (often referred to as
IP-Surveillance for specific applications within security
surveillance and remote monitoring) is a system that gives
users the ability to monitor and record video over an IP
network (LAN/WAN/Internet).
High-quality individual images from the Motion JPEG
stream are easily extracted. See also JPEG and GIF.
Megapixel - See Pixel.
NTSC (National Television System Committee) - NTSC is
an analog color encoding system used in television
systems in Japan, the United States and other parts of the
Americas. NTSC defines the video signal using 525 TV
lines per frame, at a refresh rate equal to 30 frames per
second. See also PAL.
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.
NVR (Network Video Recorder) - A dedicated Network
Video Recorder (NVR) can be used to gather data streams
from remote network cameras and video servers and store
them on a hard disk. An NVR can be a standard
networked PC, or a dedicated video recording hard disk
server with its own software application.
MPEG-2 - 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.
PAL (Phase Alternating Line) - PAL is an analog color
encoding system used in television systems in Europe and
in many other parts of the world. PAL defines the video
signal using 625 TV lines per frame, at a refresh rate equal
to 25 frames per second. See also NTSC.
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.
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.
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.
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.
Multicast - Bandwidth-conserving technology that
reduces bandwidth usage by simultaneously delivering a
single stream of information to multiple network
recipients. See also Unicast.
Pixel (Picture Element) - 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.
Multiplexer - A multiplexer is a high-speed switch that
provides full-screen images from up to 16 analog
cameras. Multiplexers can playback everything that
happened on any one camera with no interference from
the other cameras on the system.
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.
Network camera (Network video camera) - A network
camera is a camera and computer combined in one
intelligent unit. It captures and sends live video directly
over an IP network such as a LAN, intranet or the
Internet. Users can view and/or manage the camera using
a standard web browser or application software from any
local or remote computer on a network. The camera
allows multiple authorized viewers from different
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.

(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).
physical interface and protocol for low-speed serial data
communication between devices. This is the interface that
e.g. a computer uses to talk to and exchange data with a
modem and other serial devices.
RS-485 - An upgraded version of RS-422 that supports
up to 32 devices on the same connection. RS-485 is an
electrical specification of a two-wire, half-duplex,
multipoint serial connection. It enables the configuration
of inexpensive local networks and multidrop
communications links. It offers high data transmission
speeds (up to 10Mbit/s), and as it uses a differential
balanced line over twisted pair (like RS-422), it can span
relatively large distances (4000 feet or 1200 meters).
RS-485 only specifies the electrical characteristics of the
driver and the receiver. It does not specify or recommend
any data protocol.
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.
Computer monitors do not need interlace to show the
picture on the screen, but instead show them
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.
It offers quality-of-service feedback from receivers to the
multicast group as well as support for the synchronization
of different media streams.
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.
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.
RTP (Real-Time Transport Protocol) - 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.
Proxy server - In an enterprise 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 enterprise
network from the outside network and the local firewall.
It is the firewall server that protects the enterprise
network from outside intrusion.
RTSP (Real Time Streaming Protocol) - A control
protocol, and a starting point for negotiating transports
such as RTP, multicast and Unicast, and for negotiating
codecs. 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.
PTZ (Pan Tilt Zoom) - A PTZ-enabled camera can be
remotely controlled so as to change the view from the
camera. Panning is the movement of the camera along its
horizontal axis, tilting is the movement of the camera
along its vertical axis, and zooming is the adjustment of
the zoom lens to magnify the view.
Security surveillance - Network video's advanced
functionality makes it highly suited to the applications
involved in security surveillance. The flexibility of digital
technology enhances security personnel's ability to
protect people, property and assets. Such systems are
therefore an especially attractive option for companies
currently using CCTV.
P-VOP - See VOP.
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.
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
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.

requires knowledge about the network and how to
determine the route. Some switches include the router
function. See also Router.
Simplex - In simplex operation, a network cable or
communications channel can only send information in
one direction. See also Full-duplex.
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.
SMTP (Simple Mail Transfer Protocol) - 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.
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.
SMTP authentication - An extension of SMTP, where 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.
advantages in using this particular mode of recording.
UDP (User Datagram Protocol) - UDP is a
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
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.
conditions that warrant administrative attention.
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).
Unicast - Communication between a single sender and a
single receiver over a network. A new connection is
established for each new user. See also Multicast.
SSL/TSL
UPnPTM - A set of computer network protocols that allows
the automatic peer-to-peer detection of devices on the
network. UPnP is promoted by the UPnP Forum.
(Secure Socket Layer/Transport Layer Security) - These
two protocols (SSL is succeeded by TSL) 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.
URL (Uniform Resource Locator) - An "address" on the
network.
Video camera - See Network camera and CCTV video
camera.
Video encoder (video server) - A video encoder/server
digitizes analog video signals and sends digital images
directly over an IP network, such as a LAN, intranet or the
Internet. In effect, it turns an analog video system into a
network video system and enables users to view live
images using a web browser or application software on
any local or remote computer on a network.
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.
Video management software - Video management
software supplies the means for monitoring, analyzing
and recording network video. In its simplest form, it offers
live viewing, storage and retrieval of video sequences.
Advanced applications may also provide support for
recording of live video from multiple devices, different
recording modes, search functions, remote access via a
web browser, control of PTZ devices, etc.
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.
Switch - 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

analyzing image data and differences in series of images.
This detection can, for example, be used to trigger an
alarm event in a network camera and start the upload of
images from the camera.
Video switcher - An analog video switcher sequentially
displays full screen images, from one camera after
another, typically at 3-5 seconds intervals. Other camera
sources are not recorded while the image source from one
VOP (Video Object Plane) - A VOP is an image frame in
an MPEG-4 video stream. There are several types of VOP:
- An I-VOP is a complete image frame.
- An 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.
Web camera (Webcam) - A camera that requires a
constant connection (via e.g. USB) to a PC for its
operation. See also Network camera.
Web server - A program that allows web browsers to
retrieve files from computers connected to the Internet.
The Web server listens for requests from 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.
Zoom lens - A zoom lens can be moved (zoomed) to
enlarge the view of an object to show more detail.
