14AXIS 221 - 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 the fact that it is relatively simple to configure firewalls to allow RTSP traffic.

RTP/RTSP/HTTP or RTP/RTSP/HTTPS

These two methods 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 221 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 221 can also be accessed in the following ways:

•If supported by the client, the AXIS 221 can use Motion JPEG server push to display 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/image.cgi?resolution=320x240

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

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

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