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 clients by means of Axxon PSIM or using use video players that support this protocol. Transmitting Transmission of the archive of the the Videogate and Backup archive is also supported.

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

Note that when configuring, each RTSP Server loads only one CPU core. To increase the number of rtsp streams, 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 Configuring multimedia receipt using RTSP protocol), set the multicast value to the RTSP parameter in the HKEY_LOCAL_MACHINE \SOFTWARE\AxxonSoft\PSIM\Video\TransportProtocols registry section (for 64-bit system the path is HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\AxxonSoft\PSIM\Video\TransportProtocols) on computer where the Camera object is created. For detailed information on this parameter,
see
2. see Changing the transport protocol used by IP-device.
3. 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
4. at the same time.
5. 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

(1)

4. . The Port column is displayed in the Cameras table.

5. Specify a data transmission port for each

6. camera in the Port field

(2). Bear in mind the following when specifying ports

7. . When you specify ports, note the following:

   1. The following ports are
in use
8. 1. used for each camera in the Multicast mode: nPort, nPort + 18000 (rtp), nPort + 19000 (rtcp), where

it is required to

15. 1. you still must specify camera number in the data source address (see
