Configuring the Unicast mode

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

  2. In the Cameras table, set the checkboxes next to cameras, video from which you want to display. If a camera has several streams, the default stream is transmitted.

    Info
    titleNote

    If the default stream is changed on the settings panel of the corresponding Camera object after you apply RTSP Server settings, you must click the Apply button on the settings panel of the RTSP Server object to apply changes to it as well. See also Configuration of Configuring the multistream video.

  3. If video from the camera must be received through the videogate, then select the Videogate object from the Gate drop-down list.
  4. If archive from the camera must be received from the backup archive, then select the Backup archive object from the Backup archive drop-down list.
  5. Set the Unicast checkbox if signals from all cameras must be broadcast through one port.

  6. In the RTSP port field, specify the port via which the video is transmitted.

    Info
    titleNote
    The "Windows Media Player Network Sharing" service can use the default port 554. To enable broadcasting, you must change the port or disable this service.
    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 window that opens.
  7. In the HTTP port field, specify the port for transmitting video via HTTP protocol.

Features of the Multicast mode:

  1. To get a multicast video in Axxon PSIM (see Configuring Receive multimedia receipt using stream via 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 Change 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 at 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 settings panel of the RTSP Server object.

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

  3. Specify a data transmission port for each camera in the Port field. When you specify ports, note the following:

    1. The following ports are used for each camera in the Multicast mode: nPort, nPort + 18000 (rtp), nPort + 19000 (rtcp), where nPort is a port number specified for camera in the Port column.
      For the correct operation of RTSP server in the Multicast mode, these ports must be free.
    2. Specified ports are not addressed directly. Use RTSP port to get video from all cameras in the Multicast mode (see step 5).

    3. Event Even if you specify video data port, you still must specify camera number in the data source address (see Examples of addresses to view video from RTSP Server).


  4. In the Receiver IP address field, specify the address from which the broadcast in the Multicast mode will be performed. Address must be in the range from 224.0.1.0 to 239.255.255.255. By default, the receiver IP is 224.0.1.150. When you specify Receiver IP address, note the following:

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

    2. RTSP server can broadcast only 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. When you configure several RTSP Servers in the Multicast mode, you must specify different values for them in the Receiver IP address and RTSP port fields.
  5. In the RTSP port field, 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 forwards the request to the port of the requested camera.
