1:N matching
threshold
When conducting 1:N verification, face data is collected and instantly compared with all
face templates on the system using a 1:N algorithm. This is converted into a value that is
compared to a set value. If the value of the scanned face exceeds that of the set value, the
verification has passes. If it does not, the verification fails.
Complementary
light threshold
Detect ambient light brightness. When the brightness of the surrounding environment is
less than the threshold, the complementary light is turned on; when the brightness is
greater than the threshold, the complementary light is not turned on.
The default value is 80.
Moving detection
threshold
Detect whether there is a moving person in front of the device to determine whether the
face recognition function is enabled. The default value is 100.
Face recognition
angle
To limit the face angle at face recognition, the recommended threshold is 20.
Face detection size
The size of the face when face recognition. The range is 65-320 cm. The smaller the value,
the farther the detectable distance is; otherwise, the closer it is.
Preventing
simultaneous face
recognition from
multiple entrances
When multiple devices are installed on the side-by-side entrance, please enable this
function to prevent multiple devices from simultaneously recognizing the face.
Set the threshold to three types: high, medium, and low. The higher the threshold, the
narro
wer the distance between the guide lines and the smaller the face recognition range
on the screen. When setting the threshold, it is recommended to open auxiliary line
correction function.
