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:
Navigate to the Settings tab. Click Camera Groups.
Open the camera group settings.
In the Labels, create or select one or several allocation labels. Save changes.
There are two ways to specify allocation labels:
by
findface-video-worker.yaml
configuration fileby
docker-compose.yaml
configuration file
Note
Use the same name of labels in findface-video-worker
and in the web-interface, otherwise cameras will not process.
Do the following:
Open the
/opt/findface-multi/configs/findface-video-worker/findface-video-worker.yaml
configuration file and specify the allocation labels in the dictionary format (labelsMyLabel1
,MyLabel2
in the example below).sudo vi /opt/findface-multi/configs/findface-video-worker/findface-video-worker.yaml labels: {"MyLabel1": "true", "MyLabel2": "true"}
Restart the
findface-multi-findface-video-worker-1
container.sudo docker container restart findface-multi-findface-video-worker-1
As an alternative way, you can use the configuration of docker-compose.yaml
file:
Open the
/opt/findface-multi/docker-compose.yaml
configuration file and specify the allocation labels in thefindface-video-worker
section by adding environment:sudo vi /opt/findface-multi/docker-compose.yaml ... findface-video-worker: command: [--config=/etc/findface-video-worker.yaml] depends_on: [findface-video-manager, findface-ntls, mongodb] environment: - CUDA_VISIBLE_DEVICES=0 - CFG_LABELS=MyLabel1=true;MyLabel2=true image: docker.int.ntl/ntech/universe/video-worker-cpu:ffserver-9.230407.1 logging: {driver: journald} network_mode: service:pause ...
Rebuild all FindFace Multi containers.
cd /opt/findface-multi sudo docker-compose down sudo docker-compose up -d
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. Restart the similar-labeled camera.
