AXIS 214 PTZ - Video and Audio Streams

Other methods of accessing the video stream

Video/images from the AXIS 214 PTZ can also be accessed in the following ways:

• If supported by the client, the AXIS 214 PTZ 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>/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 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

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 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 address>/mpeg4/media.amp

This path is for all supported methods, and the client will negotiate with the AXIS 214 PTZ

to determine exactly 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 will depend on the network infrastructure.

Using MPEG-4
When using MPEG-4, audio is streamed using the same protocol as the video stream.
