Descriptions
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 al-
gorithm, i.e. ignored by the terminal thus no registration and comparison
interface will be triggered.
Image quality for facial registration and comparison. The higher the
value, the clearer the image requires.
Required for facial registration and comparison.
If an object’s size is smaller than this set value, the object 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 is, 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.
This value controls the on and off of the LED light. The larger the value,
the more frequently the LED light will be turned on.
A 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 larger value is set, the comparison
interface is much easier and frequently triggered.
Detecting 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.
Helping to judge whether the visible image comes from an alive body.
The larger the value, the better the visible light anti-spoofing perform-
ance.
Using near-infrared spectra imaging to identify and prevent fake photos
and videos attack.
Wide Dynamic Range (WDR), which balances light and extends image
visibility for surveillance videos under high contrast lighting scenes and
improves object identification under bright and dark environment.
Used when WDR is turned off. This helps reduce flicker when the device’s
screen flashes at the same frequency as the light.
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.
