Configuration of multistream video

The Intellect Software System supports the use of different streams from a video camera for display on the Video Surveillance Monitor, archiving, and video analytics. For example, this feature lets you display a low-quality video signal on the monitor while writing a high-quality signal to the archive, reducing the load on the Client.

To use multistreaming over the ONVIF protocol, select ONVIF 2.X brand and 1-channel-multistream model when creating an ONVIF device (using Camera discovery tool, see Installing and configuring security system components guide). Two streams will be available.

To configure multistream settings, do the following:

1. Go the Hardware tab (1) in the System Settings dialog window.
2. In the object tree on the Hardware tab, select the previously created Camera object (2) that corresponds to the video camera for which multistream mode is to be configured. The right part of the Hardware tab shows the settings panel for the selected object.
3. On the Camera object's settings panel, go to the Advanced settings tab (3).
   
4. To enable multistream mode, check the Video stream setting box (4). This will display tabs (5) for configuring the camera's video streams.

5. By default, all streams are enabled. If it is necessary to disable unused streams, clear the check boxes that correspond to the numbers of the relevant streams (6).

6. Set the Default switch (7) to the position corresponding to the stream number that should be used in the following cases:

   1. To display video both locally and on remote clients;

   2. To send to remote clients, including the Videogate, that can record this video stream;

      Note.

      If a specific video stream is requested via Video gate, then the requested stream is send to Video gate, not the Default stream.

   3. When a video stream is not specified for the video request.

   Note.

   This stream is used, for example, to display video on the Video Surveillance Monitor if a default stream has been selected for the camera or for displaying video on the Video Surveillance Monitor of the web server.

7. Set the Video analytics switch (8) to the position corresponding to the stream number that should be used for the LPR channel, the main motion detection tool, zone detection tools, tracking detection tool and face detection tool (if an external recognizer is not used).

8. Set the Archive switch (9) to position corresponding to the number of stream that is to be recorded to the archive not upon alarm – the continuous recording is performed. 

9. Set the Archive (alarms) switch (10) to position corresponding to the number of stream that is to be recorded to the archive upon alarm.

   This stream is also used for Backup archive.

   Note.

   If different streams are selected for recording to the archive upon alarms and continuous recording, recording is performed non-stop and detection tools are enabled, then upon alarm recording of the current archive fragment is stopped in the continuous recording stream and recording of a new fragment starts in the alarm recording stream. When the alarm ends and after pre-alarm recording the continuous recording with the corresponding stream resumes.

   If the same stream is selected for recording to the archive upon alarms and continuous recording, then recording of current fragment is not stopped upon alarm.

   Note.

   If pre-alarm recording is configured, then when different streams are selected for recording to the archive and continuous recording, some archive recordings overlay as the following video fragment starts before the previous ends.

10. Configure the video streams as follows:
    
    1. Go to the tab that corresponds to the desired video stream (11).
       
    2. The Purpose field (12) displays a description of how the video stream is used.

    3. Specify the video stream's parameters (13) (see The Settings panel of the Camera object).

       Attention!

       Following video streams are available for Axis cameras:

       1. Receiving of H264/MJPEG/MPEG4 video. It is available to specify settings of video stream using the Intellect software package facilities. Settings are specified in the Video stream 1 tab.

       2-4. Stream corresponding to “Quality”, “Balanced” and “”Bandwidth” profiles. These profiles configure in the camera web-interface. Video stream 2 corresponds to the “Quality” video stream, Video stream 3 corresponds to the “Balanced” video stream, Video stream 4 corresponds to the “Bandwidth” video stream.

    4. Repeat steps a-d for the remaining video streams.
11. Click the Apply button.

This completes the process of configuring multistream mode.
