Table 2-11 Description of face parameters
Name Description
Face Threshold
Adjust the face recognition accuracy. Higher threshold means higher
accuracy.
Max. Angle of Face
Set the maximum face pose angle for face detection. Larger value
means larger face angle range. If the face pose angle is out of the
defined range, the face detection box will not appear.
Pupillary Distance
Face images require desired pixels between the eyes (called pupillary
distance) for successful recognition. The default pixel is 45. The pixel
changes according to the face size and the distance between faces
and the lens. If an adult is 1.5 meters away from the lens, the pupillary
distance can be 50 px-70 px.
Recognition Timeout (S)
If a person with access permission has their face successfully
recognized, the Access Controller will prompt face recognition
success. You can enter the prompt interval time.
Invalid Face Prompt
Interval (S)
If a person without access permission attempts to unlock the door
for several times in the defined interval, the Access Controller will
prompt face recognition failure. You can enter the prompt interval
time.
Anti-fake Threshold
Avoid false face recognition by using a photo, video, mask or a
different substitute for an authorized person's face.
