Live Detection
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.
Live Detection
Threshold
Helping to judge whether the visible image comes from an alive body. The
larger the value, the better the visible light anti-spoofing performance.
Anti-counterfeiting
with NIR
Using near-infrared spectra imaging to identify and prevent fake photos and
videos attack.
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 environment.
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.
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.
