AXIS 210/211 - Video Streams

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

traffic on the network until a client connects and requests the stream. However, as more

and more unicast clients connect, the traffic on the network will increase and may cause

congestion. Although there is a maximum of 20 unicast viewers, note that all multicast

users combined count as 1 unicast viewer.

RTP/RTSP

This unicast method is RTP tunneled over RTSP. This can be used to exploit th

e fact that it

is relatively simple to configure firewalls to allow RTSP traffic.

RTP/RTSP/HTTP

This method can also be used to traverse firewalls.

Firewalls are commonly configured to

allow the HTTP protocol, thus allowing RTP to be tunneled.

The AXIS Media Control

The recommended method of accessing live video (MPEG-4 and/or Motion JPEG) from the

AXIS 210/211 is to use the AXIS Media Control (AMC) in Microsoft Internet Explorer for

Windows. This ActiveX component is automatically installed on first use, after which it

can be configured by opening the AMC Control Panel applet from the Windows Control

Panel. Alternatively, right-click the video image in Internet Explorer.

Other methods of accessing the video stream

Video/images from the AXIS 210/211 can also be accessed in the following ways:

• If supported by the client, the AXIS 210/211 can

use Motion JPEG server push to dis-

play video. This option maintains an open HTTP connection to the browser

and sends

data as and when required, for as long as required.

• As single JPEG images in a browser

. Enter e.g. the path:

http://<IP address>/axis-cgi/jpg/imag

e.cgi?resolution=320x240

• Windows Media Player. This requires AMC and the MPEG-4 d

ecoder to be installed.

The paths that can be used are listed below in the order of preference.

• Unicast via RTP: axrtpu://<IP address>/mpeg4/media.amp

•

Unicast via RTSP: axrtsp://<IP address>/mpeg4/media.amp

• Unicast via RTSP, tunneled via HTTP: axrtsphttp://<IP address>/mpeg4/media.amp

• Multicast: axrtpm://<IP address>/mpeg4/media.amp
