In Axxon Oneenables , you to can work with virtual video cameras.

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

To create and configure a virtual camera, complete the following steps:

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

3. Select Virtual from the Model drop-down list to emulate a single-stream camera. In From the Model fielddrop-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 clip that is you want to use to imitate a video signal.

   title 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: Code Block language shell 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.
   Info
   title	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, a the video is played back endlessly. To switch to one-shot playback, set Yes for in a loop. To play the video once, select Yes in the Play the file once parameter.
   

7. Click the Apply Image Added button.

Creating and configuring a virtual camera is complete.
