Live Detection
It detects the spoof attempt using visible light images to determine if the
provided biometric source sample is of a real person (a live human being) or a
false representation.
Live Detection
Threshold
It facilitates judging whether the captured visible image is a real person (a live
human being). The larger the value, the better the anti-spoofing performance
using visible light.
Anti-spoofing using
NIR
It uses near-infrared spectra imaging to identify and prevent fake photos and
videos attack.
Binocular Live
Detection Threshold
It is convenient to judge whether the near-infrared spectral imaging is fake
photo and video. The larger the value, the better the anti-spoofing
performance of near-infrared spectral imaging.
WDR
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 environments.
Anti-flicker Mode
Used when WDR is turned off. This helps reduce flicker when the device’s
screen flashes at the same frequency as the light.
Face Algorithm
Used to update or view the Major Version and Minor Version of the face
algorithm, and to pause the update of the facial template .
Notes
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.
