Set Biometric Parameters

You can customize the face parameters to improve the face recognition performance. The configurable parameters includes application mode, face liveness level, face recognition distance, face recognition interval, wide dynamic, face 1:N security level, face 1:1 security level, ECO settings, face with mask detection, hard hat detection, and multiple faces authentication.

Table 1 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. ECO Mode (1:1) Set the matching threshold when authenticating via ECO mode 1:1 matching mode. The larger the value, the smaller the false accept rate and the larger the false rejection rate. ECO Mode (1:N) Set the matching threshold when authenticating via ECO mode 1:N matching mode. The larger the value, the smaller the false accept rate and the larger the false rejection rate
Face with Mask Detection	After enabling the face with mask detection, the system will recognize the captured face with mask picture. You can set face with mask & face 1:N level and the strategy. Reminder of Wearing If the person do not wear a face mask when authenticating, the device prompts a notification and the door will open. Must Wear If the person do not wear a face mask when authenticating, the device prompts a notification and the door keeps closed.
Hard Hat Detection	After enabling the hard hat detection, you can set the strategy. Reminder of Wearing If the person do not wear the hard hat when authenticating, the device will pop up a prompt and the door will open. Must Wear If the person do not wear the hard hat when authenticating, the device will pop up a prompt and the door will keep closed. None If the person do not wear a face mask when authenticating, the device will not prompt a notification.
Multiple Faces Authentication	After multiple faces authentication is enabled, multiple faces authentication is supported.
