Parameter Descripon
Applicaon Mode Select either others or indoor according to actual environment.
Face Liveness Level Aer enabling face an-spoong funcon, you can set the matching
security level when performing live face authencaon.
Recognion Distance Set the valid distance between the user and the camera when
authencang.
Face Recognion
Interval
The me interval between two valid connuous face recognions when
authencang.
Note
You can input the number from 1 to 10.
Wide Dynamic It is suggested to enable the WDR funcon if installing the device
outdoors.
When there are both very bright and very dark areas simultaneously in
the view, you can enable the WDR
funcon to balance the brightness of
the whole image and provide clear images with details.
Face 1:N Security Level Set the matching threshold when authencang via 1:N matching mode.
The larger the value, the smaller the false accept rate and the larger the
false rejecon rate.
Face 1:1 Security Level Set the matching threshold when authencang via 1:1 matching mode.
The larger the value, the smaller the false accept rate and the larger the
false rejecon rate.
ECO Sengs Aer enabling the ECO mode, the device will use the IR camera to
authencate 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.
