AXIS 282/AXIS 282A - Video and Audio Streams
Other methods of accessing the video stream
Video/images from the AXIS 282/AXIS 282A can also be accessed in the following ways:
• If supported by the client, the AXIS 282/AXIS 282A 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>/axis-cgi/jpg/image.cgi?resolution=CIF
• 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>/mpeg4/media.amp
• Unicast via RTSP: axrtsp://<ip>/mpeg4/media.amp
• Unicast via RTSP, tunneled via HTTP: axrtsphttp://<ip>/mpeg4/media.amp
• Unicast via RTSP, tunneled via HTTPS: axrtsphttps://<ip>/mpeg4/media.amp
• Multicast: axrtpm://<ip>/mpeg4/media.amp
Note:
<ip> = IP address.
Other MPEG-4 clients
Although it may be possible to use other clients to view the MPEG-4 stream, it is not
guaranteed to work in all cases.
For some other clients, e.g. QuickTime™ the Video Object Type must be set to
Simple
. It
may also be necessary to adjust the advanced MPEG-4 settings.
To assess the video stream from e.g. QuickTime™ the following path can be used:
rtsp://<ip>/mpeg4/media.amp
This path is for all supported methods, and the client will negotiate with the AXIS
282/AXIS 282A to determine exactly which transport protocol to use.
Note:
<ip> = IP address.
Audio transmission methods
For the AXIS 282A, the audio stream can be accessed in the Live View page when viewing
either Motion JPEG or MPEG-4.
Using Motion JPEG
The basic transmission method of audio used in conjunction with Motion JPEG video
streaming is transmission over HTTP. The video and audio streams are not synchronized
when using Motion JPEG so the streams may be slightly out of sync. The latency in any
stream should be low, but this will depend on the network infrastructure.
