Video Streams

The AXIS 209FD/FD-R/FD-R M12 provides several different image and video stream formats. The type to use depends on your requirements and on the properties of your network.

The Live View page provides access to MPEG-4 and Motion JPEG 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.

How to stream MPEG-4

This video compression standard makes good use of bandwidth, and can provide DVD-quality video streams at less than 1 Mbit/s. Note that the image settings of the MPEG-4 stream are the same for all clients.

Deciding on the combination of protocols and methods to use depends on your viewing requirements, and on the properties of your network. The options available in AMC (see page 11) 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.

Unicasting is used for video-on-demand broadcasting, so that there is no video

 

 

traffic on the network until a client connects and requests the stream.

RTP over RTSP

This unicast method (RTP tunneled over

 

 

RTSP) is useful as it is relatively simple to

Note that there is a maximum of 10 simultaneous unicast connections.

 

configure firewalls to allow RTSP traffic.

 

 

 

 

 

RTP over RTSP over HTTP

This unicast method can be used to

 

 

traverse firewalls. Firewalls are com-

 

 

monly configured to allow the HTTP pro-

 

 

tocol, thus allowing RTP to be tunneled.

 

 

 

 

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 thus not possi-

 

ble to multicast over e.g. the Internet.

 

 

Note also that all multicast viewers count as one unicast viewer in the maximum total of 10 simultaneous connections.

 

 

 

AMC will negotiate with the camera to determine exactly which transport protocol to use in the order listed above. This order can be changed and the options disabled, to suit any specific requirements.

Important!

MPEG-4 is licensed technology. The AXIS 209FD/FD-R/FD-R M12 includes one viewing client license. Installing additional unlicensed copies of the viewing client is prohibited. To purchase addi- tional licenses, contact your Axis reseller.
