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,

Unicasting is used for video streaming, so that there is

 

even if some images are dropped.

 

 

no video traffic on the network until a client connects

RTP over RTSP

This unicast method (RTP tunneled over

and requests the stream.

 

RTSP) is useful as it is relatively simple to

 

 

configure firewalls to allow RTSP traffic.

Note that there are a maximum of 20 simultaneous

 

 

unicast connections.

RTP over RTSP over

This unicast method can be used to traverse

 

HTTP

firewalls. Firewalls are commonly configured

 

 

to allow the HTTP protocol, 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 cli-

 

ents 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 tech- nology. Installing additional unlicensed copies of the viewing client is prohibited. To purchase additional licenses, con- tact your Axis reseller.
