AXIS 211M - Video Stream

Video Stream

The AXIS 211M 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 211M provides access to MPEG-4 and Motion JPEG video streams, as well as 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 available options in AMC are:

Unicast RTP

This method (RTP over UDP) should be your first con-

 

 

sideration for live video , especially when it is impor-

 

 

tant to always have an up-to-date video stream, even

Unicasting is used for video-on-demand

 

if some images are dropped.

 

 

broadcasting, so that there is no video traf-

 

 

RTP over RTSP

This unicast method (RTP tunneled over RTSP) is use-

fic on the network until a client connects

 

ful as it is relatively simple to configure firewalls to

allow RTSP traffic.

Note: There is a maximum of 20 simulta-

 

 

neous viewers.

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.

 

 

 

 

Multicast RTP

This method (RTP over UDP) should be your first con-

Multicasting provides the most efficient

taneously. 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, e.g.

 

 

the Internet.

 

 

 

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 211M includes one viewing client license. Installing additional unlicensed copies of the viewing client is prohibited. To purchase additional licenses, contact your Axis reseller.
