AXIS 211W - Video Stream

Video Stream

The AXIS 211W 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 211W 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:

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

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