In Axxon One, you can work with virtual cameras.

This method requires running Axxon One in the test mode and imitating a stream of video data by playing an available video. You can play videos using video compression algorithms supported by Axxon One (see Characteristics of Axxon One).

To create and configure a virtual camera:

  1. Run the IP Device Discovery Wizard (see Searching, adding, configuring, and removing IP devices).
  2. From the Vendor drop-down list, select Virtual.

  3. Select Virtual from the Model drop-down list to emulate a single-stream camera. From the Model drop-down list, select Virtual several streams to emulate a camera supporting multiple streams.

  4. Click the button.

  5. In the Folder field, specify the storage location of the video that you want to use to imitate a video signal.

    Attention!

    • You must not use video with B-frames. You can check the presence of B-frames in a video using the ffprobe utility that is included in the FFmpeg package:
      ffprobe -v error -select_streams v:0 -show_entries stream=has_b_frames -of default=noprint_wrappers=1:nokey=1 d:\Dev\!temp\1.avi
      where, instead of d:\Dev!temp\1.avi, specify the actual path to the file. The output value:
      • 0—there are no B-frames in the video.
      • greater than 0—the video contains B-frames.
    • You must not use the H.263 codec. You can identify the codec, for example, using the MediaInfo utility.
    • If there are many files in the folder, they are played in a random order.
    • Scanning for files in a specified directory is limited to one minute.

  6. By default, the video is played in a loop. To play the video once, select Yes in the Play the file once parameter.

  7. Click the Apply button.

Creating and configuring a virtual camera is complete.
