Other Methods Of Accessing The Video Stream - Axis 213 PTZ User Manual

Other methods of accessing the video stream

Video/images from the AXIS 213 PTZ can also be accessed in the following ways:
• If supported by the client, the AXIS 213 PTZ 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 the path: http://<IP address>/axis-cgi/jpg/image.cgi?resolu-
tion=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 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
Other MPEG-4 clients
Although it may be possible to use other clients to view the MPEG-4 stream, this is not guaranteed by Axis.
For other clients, such as 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 QuickTime™ the following path can be used:
rtsp://<IP address>/mpeg4/media.amp
This path is for all supported methods, and the client negotiates with the AXIS 213 PTZ to determine which
transport protocol to use.
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 depends on the
network infrastructure.
Using MPEG-4
When using MPEG-4, audio is streamed using the same protocol as the video stream.
When audio is transmitted using MPEG-4, the Axis product sends synchronization information along with
the streams to the client that is performing the synchronization.
Audio is streamed from the client to the server over HTTP when using Motion JPEG and MPEG-4.
Accessing the Audio Streams
In addition to accessing audio in the Live View page using AMC, audio from the Video Server can also be
accessed in the following ways:
HTTP-API
You can read about accessing audio for the other protocols through the HTTP-API at
http://www.axis.com/techsup.
QuickTime/Windows Media Player
It is possible to use QuickTime and Windows Media Player to listen to the audio stream using the same
methods to access video streams.
