AXIS 207/207W - Video Streams 13

Video Streams

The AXIS 207/AXIS 207W provides several different image and video stream formats. The type to use depends on your requirements and on the properties of your network.

The Live View page in the AXIS 207/AXIS 207W 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 high-quality video streams at less than 1 Mbit/s. Note that the image settings of the MPEG-4 stream are the same for all clients.

Deciding on the combination of protocols and methods to use depends on your viewing requirements, and on the properties of your network. The available options in AMC are:

Unicast RTP

walls. Firewalls are commonly configured to

 

 

allow the HTTP protocol, thus allowing RTP to be

 

 

tunneled.

 

 

 

 

Multicast RTP

This method (RTP over TCP) 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 possible to multicast over e.g. the Internet.

 

Note also that all multicast viewers count as one unicast viewer in the maximum total of 10 simulta-

 

neous connnections.

 

 

 

 

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 207/AXIS 207W includes one viewing cli- ent license. Installing additional unlicensed copies of the viewing client is prohibited. To purchase additional licenses, contact your Axis reseller.
