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.

Enable Video Recorder 

To enable Video Recorder, do the following:

Enable the findface-video-worker service to transfer video chunks to the findface-video-storage service.

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:
1. Open the /opt/findface-multi/configs/findface-video-worker/findface-video-worker.yaml configuration to enable findface-video-worker service that will supply Video Recorder with video.
```
sudo vi /opt/findface-multi/configs/findface-video-worker/findface-video-worker.yaml
```
2. Set enabled: true in the recorder section.
```
recorder:
  enabled: true
  ...
```
3. Restart findface-multi-findface-video-worker-1 container.
```
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.py configuration file.
```
sudo vi /opt/findface-multi/configs/findface-multi-legacy/findface-multi-legacy.py
```

Find the FFSECURITY_UI_CONFIG -> vms section.

The list of vms parameters to configure is the following:

Parameter	Description
`vms` -> `"enabled"`	Set `True` to add the Record video checkbox to camera settings.
`vms` -> `"video_player"`	Set `True` to enable the video player camera settings to open in event notifications and camera preview (instead of static frames). This setting requires `"enabled": True`.

Find the FFSECURITY_UI_CONFIG -> video_player section.

The list of video player parameters to configure is the following:

Parameter	Description
`"overlay"` -> `"objects"`	Defines the settings for displaying bbox and attribute data to the objects `"faces"`, `"bodies"`, `"cars"`. Set `True` or `False` to enable/disable bbox and attribute data display for the relevant objects.
`"overlay"` -> `"gdpr"`	Set `True` to blurring all unmatched objects displayed on the video player. To fully comply with the personal data protection laws, follow this guide.
`"timeline"` -> `"min_zoom"`	Defines the largest possible scale on the video player timeline, seconds per pixel.
`"timeline"` -> `"max_zoom"`	Defines the smallest possible scale on the timeline, seconds per pixel.
`"timeline"` -> `"objects"` -> `"events"` `"faces"` -> `"enabled"`	Set `True` to enable marking face events on the timeline.
`"timeline"` -> `"objects"` -> `"events"` `"faces"` -> `"limit"`	The maximum number of face events simultaneously marked on the timeline. If there is more face events than that, you will be asked to zoom in.
`"timeline"` -> `"objects"` -> `"events"` `"faces"` -> `"matchedColor"`	Color of the matched face events.
`"timeline"` -> `"objects"` -> `"events"` `"faces"` -> `"unmatchedColor"`	Color of the unmatched face events.
`"timeline"` -> `"objects"` -> `"events"` `"bodies"` -> `"enabled"`	Set `True` to enable marking bodies events on the timeline.
`"timeline"` -> `"objects"` -> `"events"` `"bodies"` -> `"limit"`	The maximum number of body events simultaneously marked on the timeline. If there is more body events than that, you will be asked to zoom in.
`"timeline"` -> `"objects"` -> `"events"` `"bodies"` -> `"matchedColor"`	Color of the matched body events.
`"timeline"` -> `"objects"` -> `"events"` `"bodies"` -> `"unmatchedColor"`	Color of the unmatched body events.
`"timeline"` -> `"objects"` -> `"events"` `"cars"` -> `"enabled"`	Set `True` to enable marking vehicle events on the timeline.
`"timeline"` -> `"objects"` -> `"events"` `"cars"` -> `"limit"`	The maximum number of vehicle events simultaneously marked on the timeline. If there is more vehicle events than that, you will be asked to zoom in.
`"timeline"` -> `"objects"` -> `"events"` `"cars"` -> `"matchedColor"`	Color of the matched vehicle events.
`"timeline"` -> `"objects"` -> `"events"` `"cars"` -> `"unmatchedColor"`	Color of the unmatched vehicle events.
`"timeline"` -> `"objects"` -> `"episodes"` `"humans"` -> `"enabled"`	Set `True` to enable marking human episodes on the timeline.
`"timeline"` -> `"objects"` -> `"episodes"` `"humans"` -> `"limit"`	The maximum number of humans episodes simultaneously marked on the timeline. If there is more face episodes than that, you will be asked to zoom in.
`"timeline"` -> `"objects"` -> `"episodes"` `"humans"` -> `"matchedColor"`	Color of the matched human episodes.
`"timeline"` -> `"objects"` -> `"episodes"` `"humans"` -> `"unmatchedColor"`	Color of the unmatched human episodes.
`"timeline"` -> `"objects"` -> `"episodes"` `"cars"` -> `"enabled"`	Set `True` to enable marking vehicle episodes on the timeline.
`"timeline"` -> `"objects"` -> `"episodes"` `"cars"` -> `"limit"`	The maximum number of vehicle episodes simultaneously marked on the timeline. If there is more vehicle episodes than that, you will be asked to zoom in.
`"timeline"` -> `"objects"` -> `"episodes"` `"cars"` -> `"matchedColor"`	Color of the matched vehicle episodes.
`"timeline"` -> `"objects"` -> `"episodes"` `"cars"` -> `"unmatchedColor"`	Color of the unmatched vehicle episodes.

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.
