AXIS 241Q/S/QA/SA - Video and Audio Streams
16
Other methods of accessing the video stream
Video/images from the Video Server can also be accessed in the following ways:
• If supported by the client, the Video Server 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
Notes:
• <ip> = IP address.
• # = video source number or the quad stream. This is set to 1 if omitted.
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 Video Server
to determine exactly which transport protocol to use.
Notes:
• <ip> = IP address.
• # = video source number or the quad stream. This is set to 1 if omitted.
Audio transmission methods
The audio stream can be accessed in the Live View page when viewing either Motion JPEG
or MPEG.
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.
