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 on several cameras. Each RTSP Server entity runs in a separate system process (StreamingServer.run).

Creating the RTSP Server object 

Create the RTSP Server object as follows:

1. In the context menu of the Computer object select Create object => → RTSP Server.
2. Specify the name and ID of the object in the opened panel.
   
3. Click the Apply button to create the object.

Configuring the Unicast

...

mode

1. Open the settings panel for the RTSP Server object. For this select the created object in the Axxon PSIM objects tree.
   

2. In the Cameras table set the checkboxes next to video cameras video from which is to be displayed (1). If camera has several streams, the default stream is broadcasted.

   Info
   title Note.
   If default stream is changed on the corresponding Camera object settings panel after applying RTSP Server settings, it is mandatory to click Apply on the RTSP Server object settings panel to apply changes to it as well. See also Configuration of multistream video.

   
   

3. If video from the camera is to be received through the video gate, then select the Video gate object in the Gate drop-down list (2).
4. If archive from the camera is to be received from the backup archive, then select the Backup archive object in the Backup arch. drop-down list (3).
5. Set the Unicast checkbox checked if signals from all cameras are to be broadcast through one port (4).
   

6. In the RTSP port field specify the port via which the video is transmitted (5).

   Info
   title Note.
   The "Windows Media Player Network Sharing" service can use the default port 554. Change the port number or disable this service for broadcast. To disable the service go to the Control panel → Administrative Tools → Services and double-click the service name and click the Stop button in the opened window.

   
   

7. In the HTTP port field specify the port that is to be used for transmitting video via http-protocol (6).

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 Changing the transport protocol used by IP-device.
2. 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 the same time.
3. 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 by reducing the amount of transmitted data. To distribute the transmitted signal among different RTSP ports, do the following:

1. Go to the RTSP Server object settings panel.

2. Set the Multicast checkbox (1). The Port column is displayed in the Cameras table.

3. Specify a data transmission port for each video camera in the Port field (2). Bear in mind the following when specifying ports:

   1. The following ports are in use for each camera in the Multicast mode: nPort, nPort + 18000 (rtp), nPort + 19000 (rtcp), where nPort – port number specified for camera in the Port column.
      For proper operation of RTSP server in the Multicast mode these ports are to be vacant.
   2. Specified ports are not addressed directly. Use RTSP port to get video from all cameras in the Multicast mode (see item 12).

   3. In spite of specifying video data port it is required to specify camera number in the data source address (see the table below).

To distribute transmitted signal among different RTSP-ports proceed as follows:

1. Go to the RTSP Server object settings panel.

2. Set the Multicast checkbox (1). The Port column is displayed in the Cameras table.

3. Specify a data transmission port for each video camera in the Port field (2). Bear in mind the following when specifying ports:

   1. The following ports are in use for each camera in the Multicast mode: nPort, nPort + 18000 (rtp), nPort + 19000 (rtcp), where nPort – port number specified for camera in the Port column.
      For proper operation of RTSP server in the Multicast mode these ports are to be vacant.
   2. Specified ports are not addressed directly. Use RTSP port to get video from all cameras in the Multicast mode (see item 12).

   3. In spite of specifying video data port it is required to specify camera number in the data source address (see the table below).

   Info
   title Note.
   Use of the Multicast mode allows decreasing Server load due to reduction of transmitted data.

   Info
   title Note.
   To get such 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. Detailed information on this parameter see in Changing the transport protocol used by IP-device section.

   Info
   title Note.
   RTSP Server can translate both in Multicast and Unicast modes simultaneously. Receiving both these streams on the Axxon PSIM client is impossible due to RTSP key defining the mode (see the note above). However, the VLC player allows receiving streams in both modes in the same time.

   In the Receiver IP address field (3) specify the address from which the broadcast in Multicast mode will be performed. Address is to be in range from 224.0.1.0 to 239.255.255.255. By default, the receiver IP is 224.0.1.150. Bear in mind the following when specifying Receiver IP address:

   1. 224.0.0.0-224.0.0.255 address range is reserved for routing protocols and other service protocols. Destination IP address cannot be set from the specified range.

   2. RTSP-server can broadcast to one network simultaneously. The network with minimal metric is selected by default. To change the broadcast network, go to the Advanced settings tab (see below).

   3. Set different Receiver IP address and RTSP port if several RTSP Servers are in Multicast mode.
4. In the RTSP port field (4) specify the number of port through which video signal will be sent in the Multicast mode. When requesting video data from the camera using the RTSP protocol, it is necessary to specify this port. The system itself forwards the request to the port of the requested camera.
