AXIS 212 PTZ - Video Streams

MPEG-4 clients

AXIS Media Control (AMC)

The recommended method of accessing live video (MPEG-4 and Motion JPEG) from the AXIS 212 PTZ is to use the AXIS Media Control (AMC) in Microsoft Internet Explorer in Windows.

The AMC control panel can be used to configure various video and audio settings. Please see the readme file included in the tool for more information.

The AMC control panel is automatically installed on first use, after which it can be configured.

Open the AMC Control Panel from:

•Windows Control Panel (from the Start menu)

•Alternatively, right-click the video image in Internet Explorer and click Settings in the menu.

QuickTime™ & Real Player™

To access the video stream from e.g. QuickTime™ or Real Player™ the following paths can be used:

•rtsp://<ip>/mpeg4/media.amp

•rtsp://<ip>/mpeg4/media.3gp

Notes: • The AXIS 212 PTZ supports QuickTime 6.5.1 (or later) and Real Player 10.5 (or later)

•QuickTime adds latency to the video and audio stream (up to 3 seconds)

•It may be possible to use other players to view the MPEG-4 stream using the paths above, although this is not guaranteed by Axis

•<ip> = IP address

Motion JPEG

This format uses standard JPEG still images for the video stream. These images are then displayed and updated at a rate sufficient to create a stream that shows constantly updated motion.

The Motion JPEG stream uses considerable amounts of bandwidth, but provides excellent image quality and access to each and every individual image contained in the stream. The recommended method of accessing Motion JPEG live video from the AXIS 212 PTZ is to use the AXIS Media Control (AMC) in Microsoft Internet Explorer in Windows.

Note also that multiple clients accessing Motion JPEG streams can use different image settings.

Alternative methods of accessing the video stream

Video/images from the AXIS 212 PTZ can also be accessed in the following ways:

•Motion JPEG server push (if supported by the client, e.g. Mozilla/Firefox/Safari 2.0 and later). This option maintains an open HTTP connection to the browser and sends data as and when required, for as long as required. See HTML Examples, on page 20.

•Still JPEG images in a browser. Enter e.g. the path: http://<ip>/axis-cgi/jpg/image.cgi?resolution=320x240

•Windows Media Player. This requires AMC and the MPEG-4 viewing client 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

•Multicast: axrtpm://<ip>/mpeg4/media.amp
