1:N Threshold Value
Under 1:N 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 65 to 120. The higher the threshold is, the lower the
misjudgment rate, the higher the rejection rate, and vice versa. It is
recommended to set the default value of 75.
