LED Light Triggered
Threshold
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.
Motion Detection
Sensitivity
It is to set the value for the amount of change in a camera’s field of view, which
is known
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 the motion detection
frequently triggered.
Live Detection
Detecting the spoof attempt using visible light images to determine if the
provided biometric source sample is really a person ( a live human being) or
false representation.
Live Detection
Threshold
Facilitates to judge whether the captured visible image is really a person (a live
human being). The larger the value, the better the anti-spoofing performance
using visible light.
Anti-counterfeiting
with NIR
Using near-
infrared spectra imaging to identify and prevent fake photos and
videos attack.
Face Algorithm
Facial algorithm related information and pause facial template update.
Notes
Improper adjustment of the exposure and
