Face Recognition

Face recognition accuracy can be adjusted. The larger the value is,
the higher the accuracy will be.
Max. Angle of Face
Recognition
Set the control panel shooting angle of profiles. The larger the value
is, the wider range of the profiles will be recognized.
Pupillary Distance
Pupillary distance is the pixel value of the image between the centers
of the pupils in each eye. You need to set an appropriate value so
that the 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
(S)
When a person who does not have the access permission 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.
