Configure Video Recorder
The FindFace Core internal architecture allows for embedding Video Recorder, an additional functionality that records, stores, and plays back video data from cameras.
This section is about the Video Recorder configuration.
In this section:
Enable Video Recorder
To enable Video Recorder, do the following:
Enable the
findface-video-workerservice to transfer video chunks to thefindface-video-storageservice.Important
This setting makes the Video Recorder functionality available over HTTP API. It’s also obligatory if you want to harness Video Recorder as part of the FindFace Multi web interface.
Do the following:
Open the
/opt/findface-multi/configs/findface-video-worker/findface-video-worker.yamlconfiguration to enablefindface-video-workerservice that will supply Video Recorder with video.sudo vi /opt/findface-multi/configs/findface-video-worker/findface-video-worker.yaml
Set
enabled: truein therecordersection.recorder: enabled: true ...
Restart
findface-multi-findface-video-worker-1container.sudo docker container restart findface-multi-findface-video-worker-1
Configure Video Recorder to work as part of the FindFace Multi web interface.
Note
Omit the following steps if you do not need the Video Recorder tools to appear in the FindFace Multi web interface.
Do the following:
Open the
/opt/findface-multi/configs/findface-multi-legacy/findface-multi-legacy.pyconfiguration file.sudo vi /opt/findface-multi/configs/findface-multi-legacy/findface-multi-legacy.py

Nuances of Disabling Video Recorder
If Video Recorder is running and recording video on selected cameras, and you need to disable it, be sure to disable video recording on the cameras first, before proceeding with the /opt/findface-multi/configs/findface-multi-legacy/findface-multi-legacy.py and /opt/findface-multi/configs/findface-video-worker/findface-video-worker.yaml configuration files.
