Configure Video Recorder

There are two methods of video archive cleanup available in the system:

1. Regular cleanup

2. Manual cleanup via a console command

In this section:

Regular Video Cleanup

To configure the regular video cleanup, do the following:

1. 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
   

2. Find the SERVICES section and set "vms_cleanup": True.

   SERVICES = {
       "ffsecurity": {
           ...
           "vms_cleanup": True,
       }
   }
   

3. Find the VMS_CLEANUP_SETTINGS section and configure what video to remove, using the following parameters:

   • 'CLEANUP_BETWEEN_TRACKS': set True to remove video intervals that do not contain recognition events.

   • 'CLEANUP_ARCHIVE': set True to remove the entire video archive older than a given number of days.

   • 'ARCHIVE_CLEANUP_AGE': the maximum age of a video archive in the system, days. Applicable if 'CLEANUP_ARCHIVE': True.

   • 'BETWEEN_TRACKS_CLEANUP_START_AGE': time period (days) during which the entire video archive is kept in the system. After this period is over, the system starts cleaning up between tracks according to the CLEANUP_BETWEEN_TRACKS settings.

   • 'KEEP_EVENT_TYPES': event types that will be kept in the video archive, in the form of a dictionary, e.g., [‘face’, ‘body’, ‘car’].

   • 'KEEP_EVENT_BEFORE_AFTER': interval before and after a track with events that won’t be removed in order to preserve meaningful information related to them, seconds. The value must be less than CLEANUP_THRESHOLD.

   • 'CLEANUP_THRESHOLD': minimum interval between tracks with events, seconds. If the interval between tracks is shorter, it won’t be removed.

   'VMS_CLEANUP_SETTINGS': {
       'CLEANUP_BETWEEN_TRACKS': True,
       'CLEANUP_ARCHIVE': True,
       'ARCHIVE_CLEANUP_AGE': 30,  # days
       'BETWEEN_TRACKS_CLEANUP_START_AGE': 0,  # days
       'KEEP_EVENT_TYPES': ['face', 'body', 'car'],
       # Add `safe_time_interval` in seconds to each `track` subject to delete
       # Prevents deletion of essential data.
       # Should be lower than CLEANUP_THRESHOLD
       'KEEP_EVENT_BEFORE_AFTER': 10,  # minimal allowed value
       # Threshold between `intervals` in seconds.
       # If duration between `tracks` < `CLEANUP_THRESHOLD`
       # interval between tracks will not be added to deletion tasks
       'CLEANUP_THRESHOLD': 360,  # minimal allowed value
   },
   

4. Find the 'VMS_CLEANUP_SERVICE_SCHEDULE' parameter and specify a recurrence rule (RRULE) for scheduling video cleanup.

   Tip

   See the RRULE calculator here.

   # rrule (recurrence rule) for scheduling `vms_cleanup` service
   'VMS_CLEANUP_SERVICE_SCHEDULE': 'RRULE:FREQ=HOURLY;INTERVAL=3;WKST=MO',
   

5. Restart all FindFace Multi containers.

   cd /opt/findface-multi/
   
   sudo docker-compose restart
   

Manual Video Cleanup

You can manually remove video chunks older than the given number of days by executing the command below. To set the number of days, use the –vms-videos-max-age argument.

sudo docker exec -it findface-multi-findface-multi-legacy-1 /opt/findface-security/bin/python3 /tigre_prototype/manage.py cleanup_vms --vms-videos-max-age=30

Enable VMS Cleanup Settings in the UI

By default, VMS cleanup settings are disabled in the UI. To work with VMS cleanup settings from the UI, configure the "vms" parameter in the /opt/findface-multi/configs/findface-multi-legacy/findface-multi-legacy.py configuration file.

1. In the FFSECURITY_UI_CONFIG section locate the "vms" parameter and set "enabled": True.

   sudo vi /opt/findface-multi/configs/findface-multi-legacy/findface-multi-legacy.py
   
   FFSECURITY_UI_CONFIG = {
       ...
       "vms": {
           "enabled": True,
           ...
       },
   }
   

2. Make sure that VMS cleanup service is enabled in the /opt/findface-multi/configs/findface-multi-legacy/findface-multi-legacy.py configuration file. Find the SERVICES section and set "vms_cleanup": True.

   SERVICES = {
       "ffsecurity": {
           ...
           "vms_cleanup": True,
       }
   }
   

3. Restart all FindFace Multi containers.

   cd /opt/findface-multi/
   
   sudo docker-compose restart
