D3 Series User Manual 10.6 Face Click Face on the WebServer. Function Name Description 1:N Threshold Value Under face verification mode, the verification will only be successful when the similarity between the acquired facial image and all registered facial templates is greater than the set value. The valid value ranges from 0 to 100. The higher the thresholds, the lower the misjudgment rate, the higher the rejection rate, and vice versa. is recommended to set the default value of 51. It P a g e | 46 Copyright2023 ZKTECO CO., LTD. All rights reserved. D3 Series User Manual 1:1 Threshold Value Under 1:1 verification mode, the verification will only be successful when the similarity between the acquired facial image and the users facial templates enrolled in the device is greater than the set value. The valid value ranges from 0 to 100. The higher the thresholds, the lower the misjudgment rate and the higher is the rejection rate, and vice versa. It is recommended to set the default value of 63. Face Enrollment Threshold During face enrolment, 1: N comparison is used to determine whether the user has already registered before. When the similarity between the acquired facial image and all registered facial templates is greater than this threshold, it indicates that the face has already been registered. The pitch angle tolerance of a face for facial registration and comparison. Face Pitch Angle If a faces pitch angle exceeds this set value, it will be filtered by the algorithm, i.e. ignored by the terminal thus no registration and comparison interface will be triggered. Face Rotation Angle The rotation angle tolerance of a face for facial template registration and comparison. If a faces rotation angle exceeds this set value, it will be filtered by the algorithm, i.e. ignored by the terminal thus no registration and comparison interface will be triggered. Image Quality Image quality for facial registration and comparison. The higher the value, the clearer the image requires. Minimum Face Size Required for facial registration and comparison. If the minimum size of the captured figure is smaller than this set value, then it will be filtered off and not recognized as a face. This value can be understood as the face comparison distance. The farther the person is, the smaller the face is, and the smaller the face pixel will be obtained by the algorithm. Therefore, adjusting this parameter can adjust the furthest comparison distance of faces. When the value is 0, the face comparison distance is not limited. LED Light Triggered Value 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 cameras 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. P a g e | 47 Copyright2023 ZKTECO CO., LTD. All rights reserved. D3 Series User Manual Anti-flicker Mode Used when WDR is turned off. This helps reduce flicker when the devices screen flashes at the same frequency as the light. 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 a 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-spoofing Using NIR Using near-infrared spectra imaging to identify and prevent fake photos and video attacks. Note: Improper adjustment of the exposure and quality parameters may severely affect the performance of the device. Please adjust the exposure parameter only under the guidance of the after-

sales service personnel of our company. 10.7 Access Control Options Click Access Control Options on the WebServer.
