Table 7-2 Face Picture Parameters
Parameter
Description
Application Mode
Select either others or indoor according to actual environment.
Face Liveness Level
After enabling face anti-spoofing function, you can set the matching
security level when performing live face authentication.
Face Recognition
Distance
Set the valid distance between the user and the camera when
authenticating.
Face Recognition
Interval
The time interval between two continuous face recognitions when
authenticating.
Note
You can input the number from 1 to 10.
Wide Dynamic
It is suggested to enable the WDR function if installing the device
outdoors.
When there are both very bright and very dark areas simultaneously in
the view, you can enable the WDR function to balance the brightness of
the whole image and provide clear images with details.
Face 1:N Security Level Set the matching threshold when authenticating via 1:N matching mode.
The larger the value, the smaller the false accept rate and the larger the
false rejection rate.
Face 1:1 Security Level Set the matching threshold when authenticating via 1:1 matching mode.
The larger the value, the smaller the false accept rate and the larger the
false rejection rate.
ECO Settings
After enabling the ECO mode, the device will use the IR camera to
authenticate faces in the low light or dark environment. And you can set
the ECO mode threshold, ECO mode (1:N), and ECO mode (1:1).
ECO Threshold
When enabling the ECO mode, you can set the ECO mode’s threshold.
The larger the value, the easier the device entering the ECO mode.
