information

The RTSP Server object is used for transmitting video from Server server to remote workplaces workstations using the RTSP protocol. Use The use of the RTSP protocol allows viewing you to view video from IP cameras and video archive on remote clients by means of the Axxon PSIM software or using use video players that support this protocol.  Transmitting Video gate archive Transmission of the archive of the Videogate and Backup archive is also supported.

If there is sound with a live video with audio or the archive is recorded with soundaudio, then video broadcast transmission with sound audio through RTSP Server is supported – for supported—for this specify the ID of microphone from which the archive is recorded when requesting video (see the table with requests examples). For proper operation of this feature set the VLC media Examples of addresses to view video from RTSP Server). For the audio to play correctly in VLC Media Player, set the VLC player compatibility mode checkbox checked in VLC Media Player (see item 14below).

Note that when configuring, each RTSP Server It is to be taken into account that while configuring each rtsp Server loads only one CPU core. To increase the number of rtsp streams several rtsp Server objects are to be created and configured , you must create several RTSP Server objects and configure them on several cameras. Each RTSP Server entity runs in a separate system process (StreamingServer.run).

Configuring the Multicast mode

Features of the Multicast mode:

1. To get a multicast video in Axxon PSIM (see

For detailed information on this parameter,

5. device.
6. RTSP Server can broadcast simultaneously in Multicast and Unicast modes. Receiving both such streams on the Axxon PSIM client is impossible due to RTSP key, which determines the connection mode (see above). However, the VLC player allows receiving streams in both modes
in
7. at the same time.
8. The ports that are assigned to each camera in this mode will not be displayed in the Windows OS Resource Monitor and other similar operating system resource monitors.

Using the Multicast mode allows you to reduce the load on the Server server by reducing the amount of transmitted data. To distribute the transmitted signal among different RTSP ports, do the following:

1. Go to the settings panel of the RTSP Server object
settings panel
2. .

3. Set the Multicast checkbox
