In Axxon PSIM, you can use different streams from the camera for displaying video on the video surveillance monitor, archiving, and video analytics. For example, this option lets you display a low-quality video on the monitor while recording a high-quality video to the archive, which reduces the load on the client.

Note

To use multistreaming via the ONVIF protocol, select the ONVIF 2.X brand and 1-channel-multistream model when creating the ONVIF device (using the Camera discovery tool, see Installing and configuring security system components guide). You can use two streams.

In multistreaming mode, there are situations where changes of some video stream parameters can affect others without any user notification. It is due to the model and firmware of the camera, since some cameras don't support user selection of the resolution, codec, and so on.

To configure multistream settings, do the following:

  1. Go to the Hardware tab in the System settings window.
  2. In the object tree on the Hardware tab, select the previously created Camera object that corresponds to the camera for which you want to configure multistreaming mode.
  3. Go to the Streams settings tab on the settings panel of the Camera object.
  4. Set the Streams configuring checkbox to enable multistreaming mode.
  5. Set the checkboxes next to the used video streams of the camera (1).

  6. Set the checkbox in the Default column next to the stream number that you need to use 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 Videogate, then the requested stream, not the Default one, is transmitted.

    3. When a video request doesn't contain a specified video stream.

      Note

      You can use this stream, 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 checkbox in the Video analytics column next to the stream number that you need to use for the face recognition server, the main motion detector, zone detectors, tracking detectors, and face detectors (if an external recognizer isn't used).

  8. Set the checkbox in the Archive column next to the stream number that you need to record to the archive, not upon alarm, for example, during continuous recording. 

  9. Set the checkbox in the Archive (alarms) column next to the stream number that you need to record to the archive upon alarm.

    You can use this stream for backup archiving.

    Note

    If you select different streams for recording to the archive upon alarms and continuous recording when recording is performed nonstop and detectors are enabled, then the recording of the current archive fragment stops upon alarm in the continuous recording stream, and recording of a new fragment starts in the alarm recording stream. When the alarm ends and after post-alarm recording, the continuous recording with the corresponding stream resumes.

    If you select the same stream for recording to the archive upon alarms and continuous recording, then recording of the current fragment doesn't stop upon alarm.

    Note

    If you configure pre-alarm recording, then when selecting different streams for recording to the archive upon alarms and continuous recording, some archive recordings overlay as the following video fragment starts earlier than the previous ends.

  10. Configure the video streams as follows:
    1. Go to the tab that corresponds to the required video stream.
    2. The Purpose field displays the information on how to use a video stream.

    3. In the Codec group, specify the video stream parameters (see The settings panel of the Camera object): codec, key frame rate, and video quality.

      Attention!

      The following video streams are available for Axis cameras:

      1. Receiving H264/MJPEG/MPEG4 video. You can specify video stream settings using Axxon PSIM. Specify these settings in the Video stream 1 tab.
      2-4. Streams that correspond to the "Quality", "Balanced" and "Bandwidth" profiles. You can configure these profiles in the camera web interface. Video stream 2 corresponds to the "Quality" video stream, Video stream 3 corresponds to the "Balanced" video stream, and Video stream 4 corresponds to the "Bandwidth" video stream.

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

Configuring the multistream video is complete.
