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).

Create and configure 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.
4. Open the settings panel for the RTSP Server object. For this select the created object in the Intellect objects tree.
   

5. 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.

   
   

   Info
   title Note.
   To select several cameras at the same time, mark lines in the table and then holding down the Ctrl key on the keyboard click the unchecked box in one of the marked lines. As a result all selected lines will be set checked. To uncheck several boxes at the same time, do the same, but click the checked box after the selection of the lines.

   
   

6. 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).
7. Set the Unicast checkbox checked if signals from all cameras are to be broadcast through one port (3).
   

8. In the RTSP port field specify the port via which the video is transmitted (4).

   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.

   
   

9. In the HTTP port field specify the port that is to be used for transmitting video via http-protocol (5).

10. To distribute transmitted signal among different RTSP-ports set the Multicast checkbox (1). In the Cameras table the Port column is displayed (2), in which it is necessary to specify a data transmission port for each video camera. 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 Intellect (see Configuring multimedia receipt using RTSP protocol) set the multicast value to the RTSP parameter in the HKEY_LOCAL_MACHINE \SOFTWARE\ITV\Intellect\Video\TransportProtocols registry section (for 64-bit system the path is HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ITV\Intellect\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 Intellect 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.

    
    

11. 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.

    Note

    title	Important!

    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

    . InfotitleNote

    1. .

    2. RTSP-server can broadcast to one network simultaneously. The network with minimal metric is selected by default. To change the broadcast network,

    create the IpInterface = "IP-address of required interface" key in the registry. See also Registry keys reference guide

    1. go to the Advanced settings tab (see below).

    2. Set different Receiver IP address and RTSP port if several RTSP Servers are in Multicast mode.
12. 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.
13. Go to the Advanced settings tab.
    

14. If the current time is to be sent to VLC Media Player instead of the frame time, then set the VLC player compatibility mode checkbox checked (1). This option is to be used in case of problems when playing back the archive received over RTSP in VLC Media Player.

15. If there are captions on the video (see Configuring captions display on a video image), set the Use captions track checkbox checked to send them along with video via RTSP Server and to display them in the receiving app – VLC player (2).

    Note
    title Important!
    Correct video and captions operation are enabled only in VLC Media Player 2.0.0. These features are not guaranteed to work in other versions of VLC Media Player or other programs.

    
    

16. From the Source IP interface drop-down list, select the name of the network interface that should be used to broadcast the RTSP server (3).

17. If the RTSP Server is used for broadcasting the video data to the Single Data Center (ECHD), and the Video Surveillance Servers are behind NAT, then it is necessary to specify the NAT settings:

    1. In the IP addr field, specify the IP address of the router that performs the NAT broadcasting (4).

    2. In the Port field, specify the port of the router, which is accessed by the client when executing the Single Data Center (ECHD) requests (5).

       Info
       title Note
       To enable the substitution of the router's specified IP address and port to the Single Data Center (ECHD) requests, it is necessary to set the corresponding checkbox in the settings panel of the Web server object - see Enabling the processing of ECHD requests and selecting rtsp server.

       
       

18. Click the Apply button to save the changes.
