11
AXIS M3011 - Video Streams
Video Streams
The network camera provides several image and video stream formats. Your requirements and the properties of your network
will determine the type you use.
The Live View page in the network camera provides access to H.264, Motion JPEG, and MPEG-4 video streams, and to the list
of available stream profiles. Other applications and clients can also access these video streams/images directly, without going
via the Live View page.
How to stream MPEG-4/H.264
This video compression standard makes good use of bandwidth, and can provide high quality video streams at less than 1
Mbit/s.
Deciding the combination of protocols and methods to use depends on your viewing requirements, and on the properties of
your network. The available options in AMC are:
Unicast RTP This unicast method (RTP over UDP) should
be your first consideration for live unicast
video, especially when it is important to
always have an up-to-date video stream,
even if some images are dropped.
RTP over RTSP This unicast method (RTP tunneled over
RTSP) is useful as it is relatively simple to
configure firewalls to allow RTSP traffic.
RTP over RTSP over
HTTP
This unicast method can be used to traverse
firewalls. Firewalls are commonly configured
to allow the HTTP protocol, thus allowing
RTP to be tunneled.
Unicasting is used for video streaming, so that there is
no video traffic on the network until a client connects
and requests the stream.
Note that there are a maximum of 20 simultaneous
unicast connections.
Multicast RTP This method (RTP over UDP) should be used for live multicast video. The video stream is always
up-to-date, even if some images are dropped.
Multicasting provides the most efficient usage of bandwidth when there are large numbers of clients viewing simultaneously. A multicast broadcast cannot however, pass a network router unless
the router is configured to allow this. It is not possible to multicast over the Internet, for example.
Note also that all multicast viewers count as one unicast viewer in the maximum total of 20
simultaneous connections.
AMC negotiates with the camera to determine the transport protocol to use in the order listed above. This order can be
changed and the options disabled, to suit specific requirements.
Important!
H.264 and MPEG-4 are licensed technologies. The network camera includes one viewing client license for each technology. Installing additional unlicensed copies of the viewing client is prohibited. To purchase additional licenses, contact your Axis reseller.
12
AXIS Media Control (AMC)
AXIS Media Control (AMC) in Microsoft Internet Explorer in Windows is
the recommended method of accessing live video from the network
camera.
The AMC control panel can be used to configure various video and audio
settings. Please see the AMC user manual included in the tool for more
information.
The AMC control panel is automatically installed on first use, after which
it can be configured.
Open the AMC Control Panel from:
• Windows Control Panel (from the Start menu)
• Alternatively, right-click the video image in Internet Explorer and
click Settings to access the AMC window.
Note:
AXIS M3011 does not support audio.
Motion JPEG
AXIS M3011 - Video Streams
This format uses standard JPEG still images for the video stream. These images are then displayed and updated at a rate
sufficient to create a stream that shows constantly updated motion.
The Motion JPEG stream uses considerable amounts of bandwidth, but provides excellent image quality and access to every
image contained in the stream. The recommended method of accessing Motion JPEG live video from the network camera is to
use the AXIS Media Control (AMC) in Microsoft Internet Explorer in Windows.
Alternative methods of accessing the video stream
You can also access video/images from the network camera in the following ways:
• Motion JPEG server push (if supported by the client, Firefox, for example). This option maintains an open HTTP connection to the browser and sends data as and when required, for as long as required.
• Still JPEG images in a browser. Enter the path - http://<ip>/axis-cgi/jpg/image.cgi
• Windows Media Player. This requires AMC and the MPEG-4/H.264 viewing client to be installed. The paths that can be
used are listed below in the order of preference:
• Unicast via RTP: axrtpu://<ip>/axis-media/media.amp?videocodec=<codec>
• Unicast via RTSP: axrtsp://<ip>/axis-media/media.amp?videocodec=<codec>
• Unicast via RTSP, tunneled via HTTP: axrtsphttp://<ip>/axis-media/media.amp?videocodec=<codec>
• Multicast: axrtpm://<ip>/axis-media/media.amp?videocodec=<codec>
• To access the video stream from QuickTime™ the following paths can be used:
• rtsp://<ip>/axis-media/media.amp?videocodec=<codec>
• rtsp://<ip>/axis-media/media.3gp?videocodec=<codec>
Notes:
• The network camera supports QuickTime 6.5.1 and later.
• QuickTime adds latency to the video stream (up to 3 seconds).
• It may be possible to use other players to view the MPEG-4/H.264 stream using the paths above, although Axis does
not guarantee this.
• <ip> = IP address
• <codec> = h264 or mpeg4. The default codec is H.264.

•MJPEG
Image
Image Appearance
Use these settings to modify the image resolution
and compression. Setting the compression level
affects the image quality and the amount of
bandwidth required; the lower the compression, the
higher the image quality with higher bandwidth
requirements.
See the online help files for more information.
Video Stream
To avoid bandwidth problems on the network, the frame rate allowed to each viewer can be limited. Select the Unlimited
radio button option to allow the highest available frame rate; or select the Limited to radio button option and enter a value
(1-30) fps in the field.

MPEG-4 & H.264
GOV Settings
The GOV structure describes the composition of the H.264
video stream which consists of 2 image forms, I-images
and P-images. An I-image is a complete image, whereas a
P-image is only the differences in the image as compared
with the previous image.
The GOV length determines how many P-images are sent before the next complete I-image is sent.
Setting the GOV-length to a higher value saves considerably on bandwidth but if there is congestion on the network, there
may be noticeable decay in the video quality. Setting the GOV-length to a lower value increases the video quality, in this case.
GOV length should not be higher than the set frame rate when using a pre-trigger buffer see Pre- and post-trigger buffers, on
page 24.
