Video Wall

FindFace Multi allows for basic video surveillance. Use the Video Wall to display the video image from cameras and video files.

In this chapter:

Configure Video Wall

You can set up the Video Wall features that determine how it highlights objects in the video:

• turn on/off the bbox and attribute data display for faces, cars, and bodies

  Note

  The attribute data are displayed if you have previously enabled neural networks for attribute recognition. See Enable Face Attribute Recognition, Enable Car and Car Attribute Recognition, Enable Body and Body Attribute Recognition.

• enable blurring unmatched objects to comply with personal data protection laws (GDPR and similar)

To configure the Video Wall, do the following:

1. Open the /etc/findface-security/config.py configuration file.

   sudo vi /etc/findface-security/config.py
   

2. Find the FFSECURITY_UI_CONFIG -> available_video_wall_features section.

3. Set "faces", "cars", "bodies" True or False to enable/disable the bbox and attribute data display for the relevant objects.

   FFSECURITY_UI_CONFIG = {
       ...
       "available_video_wall_features": {
           "faces": True,
           "cars": False,
           "bodies": True,
           ...
       }
   }
   

4. Set "gdpr": True to enable blurring all unmatched objects displayed on the Video Wall.

   Tip

   To fully comply with the personal data protection laws, follow this guide.

   FFSECURITY_UI_CONFIG = {
       ...
       "available_video_wall_features": {
           ...
           "gdpr": True
       }
   }
   

5. Restart findface-security.

   sudo systemctl restart findface-security.service
