AXIS 212 PTZ/AXIS 212 PTZ-V - Video Streams
14
The MPEG-4 standard provides scope for a large range of different coding tools for use by various applications
in different situations, and the AXIS 212 PTZ/AXIS 212 PTZ-V provides certain subsets of these tools. These are
represented as Video object types, which are selected for use with different viewing clients. The supported video
object types are:
Simple -
sets the coding type to H.263, as used by, for example, QuickTime™
Ad
vanced Simple - sets the coding type to MPEG-4 Part 2, as used by AMC (AXIS Media Control)
When using MPEG-4 it is also possible to control the bit rate, which in
turn allows the amount of bandwidth
usage to be controlled. CBR (Constant Bit Rate) is used to achieve a specific bit rate by varying the quality of the
MPEG-4 stream. When using VBR (Variable Bit Rate), the quality of the video stream is kept as constant as
possible, at the cost of a varying bit rate.
Important!
MPEG-4 is licensed technology. The AXIS 212 PTZ/AXIS 2
12 PTZ-V includes one viewing client license.
Installing additional unlicensed copies of the viewing client is prohibited. To purchase additional licenses,
contact your Axis reseller.
Alternative methods of accessing the video stream
Video/images from the AXIS 212 PTZ/AXIS 212 PTZ-V can also be accessed in the following ways:
If supported by the client, the AXIS 212 PTZ/AXIS 212 PTZ-V 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, for example, th
e path: http://<ip>/axis-cgi/jpg/image.cgi?resolu-

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
