Face Rotation
Angle
It is the rotation angle tolerance of a face for facial template registration and
comparison.
If a face’s rotation angle exceeds this set value, it will be filtered by the algorithm,
i.e., ignored by the terminal and, no registration and comparison interface will
be triggered.
Image Quality
It sets the image quality for facial registration and comparison. The higher the
value, the clearer the image required.
Minimum Face Size
It is required for facial registration and comparison. If an object’s size is smaller
than this set value, it will be filtered and not recognized as a face.
This value can be understood as the face comparison distance. The farther the
person is, the smaller the face will be, and the smaller the face pixel will be
obtained by the algorithm. Therefore, adjusting this parameter can adjust the
furthest comparison distance of faces. When the value is 0, the face comparison
distance is not limited.
LED Light Trigger
Value
It controls the turning on and off of the LED light. The larger the value, the more
frequently the LED light will be turning on.
Motion Detection
Sensitivity
It is the measurement of the amount of change in a camera’s field of view that
qualifies as potential motion detection that wakes up the terminal from standby
to the comparison interface. The larger the value, the more sensitive the system
would be, i.e., if a higher value is set, the comparison interface is much easily and
frequently triggered.
Live Detection
It detects a spoof attempt by determining whether the source of a biometric
sample is a live human being or a fake representation using visible light images.
Live Detection
Threshold
It helps to judge whether the visible image comes from an alive body. The larger
the value, the better the visible light anti-spoofing performance.
Anti-spoofing using
NIR
It uses near-infrared spectra imaging to identify and prevent fake photos and
videos attack.
WDR
Wide Dynamic Range (WDR) balances light and extends image visibility for
surveillance videos under high contrast lighting scenes and improves object
identification under bright and dark environments.
Anti-flicker Mode
It is used when WDR is not on. It helps reduce flicker when the device’s screen
flashes at the same frequency as the light.
Face Algorithm
Facial algorithm related information and pause facial template update.
Note:
Improper adjustment of the exposure and quality parameters may severely affect the performance of the
device. Please adjust the exposure parameter only under the guidance of the after-sales service personnel
of our company.
