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.

There are instances in multistream mode where changes to some video stream parameters may affect others–without any user notification. This is related to the video camera's model and firmware, because certain cameras do not support user selection of the resolution, codec, etc.

To configure multistream settings, do the following:

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

  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 to match the number of the stream that you want to use for displaying video locally and on remote clients (7).

    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 radio button to the number of the stream to be used by sensors (8).

  8. Set the Archive radio button to the number of the stream to be written to the archive (9).
  9. Configure the video streams as follows:
    1. Go to the tab that corresponds to the desired video stream (10).
    2. The Purpose field displays a description of how the video stream is used (11).

    3. Specify the video stream's parameters (12) (see The Settings panel of the Camera object).

      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.
  10. Click the Apply button.

This completes the process of configuring multistream mode.
