Allocate video-worker to Camera Group

In distributed architectures, it is often necessary that video streams from a group of cameras be processed in situ, without being redistributed by the main server across remote video-worker instances. Among typical use cases are hotel chains, chain stores, several security checkpoints in the same building, etc. If this is your case, simply allocate the local video-worker to the camera group.

Do the following:

1. Navigate to the Camera groups tab.

2. Open the camera group settings.

3. In the Labels, create or select one or several allocation labels. Save changes.

4. Open the video-worker configuration file and specify the allocation labels in the following format: label_name=true (label terminal_1 in the example below).

   sudo vi /etc/video-worker.ini
   
   wrk-labels=terminal_1=true
   

5. Restart video-worker.

   sudo systemctl restart video-worker.service
   

Note

If a camera is assigned an allocation label, its video stream can be processed by a video-worker instance with the same label, as well as by all unlabeled video-worker instances.

Warning

If a labeled camera is processed by an unlabeled video-worker instance and a free similar-labeled instance appears, the camera won’t automatically switch to the latter. To switch the camera, restart the similar-labeled video-worker instance.
