Recognition
You can set the control panel shooting angle of profiles. The larger the

Pupillary Distance
Pupillary distance is the pixel value of the image between the centers of

access controller can recognize faces as needed. The value changes
according to the face sizes and the distance between faces and the lens.
The closer the face is to the lens, the greater the value should be. If an
adult is 1.5 meters away from the lens, the pupillary distance value can
be within 50 to 70.
Recognition Timeout
When a person who does not have the access authority stands in front of
the access controller and gets the face recognized, the controller will
prompt that face recognition failed. The prompt interval is called
recognition timeout.
Invalid Face Prompt
Interval (S)
When a face has no access permission stands in front of the access
controller, the controller will prompt that the face is invalid. The prompt
interval is invalid face prompt interval.
