Allocate findface-video-worker to Camera Group

In a distributed architecture, it is often necessary that video streams from a group of cameras be processed in situ, without being redistributed across remote findface-video-worker instances by the principal server.

Note

Among typical use cases are hotel chains, chain stores, several security checkpoints in the same building, etc.

In this case, allocate the local findface-video-worker to the camera group.

Do the following:

1. Navigate to the Preferences tab. Click Camera Groups.

2. Open the camera group settings.

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

4. Open the findface-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/findface-video-worker-cpu.ini
   sudo vi /etc/findface-video-worker-gpu.ini
   
   labels = terminal_1=true
   

5. Restart findface-video-worker.

   sudo systemctl restart findface-video-worker-cpu.service
   sudo systemctl restart findface-video-worker-gpu.service
   

Note

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

Warning

If a labeled camera is processed by an unlabeled findface-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 findface-video-worker instance.
