Enable or disable the live face detection function. If enabling the function, the device can
recognize whether the person is a live one or not.
Note
Biometric recognition products are not 100% applicable to anti-spoofing environments. If you
require a higher security level, use multiple authentication modes.
Live Face Detection Security Level
After enabling the face anti-spoofing function, you can set the matching security level when
performing live face authentication.
Recognition Distance
Select the distance between the authenticating user and the device camera.
Application Mode
Select either others or indoor according to actual environment.
Face Recognition Mode
Normal Mode
Recognize face via the camera normally.
Deep Mode
The device can recognize a much wider people range than the normal mode. This mode is
applicable to a more complicated environment.
Continuous Face Recognition Interval
Set the time interval between two continuous face recognitions when authenticating.
Pitch Angle
The maximum pitch angle when starting face authentication.
Yaw Angle
The maximum yaw angle when starting face authentication.
Face Grading
Set the face grading according to your needs.
1:1 Matching Threshold
Set the matching threshold when authenticating via 1:1 matching mode. The larger the value,
the smaller the false accept rate and the larger the false rejection rate.
1:N Matching Threshold
Set the matching threshold when authenticating via 1:N matching mode. The larger the value,
the smaller the false accept rate and the larger the false rejection rate.
Face Recognition Timeout Value
Set the timeout value when face recognizing. If the face recognition time is longer than the
configured value, the system will pop up a prompt.
