ZKTeco SpeedFace-V5L User Manual

2.8-inch Linux Visible Light Product User Manual 27
similarity between the acquired facial image and the facial templates enrolled in the
device is greater than the set value. The valid value ranges from 55 to 120. The higher
the thresholds set, the lower the misjudgment rate, the higher the rejection rate, and
vice versa.
Face registration
threshold
During face registration, 1:N verification is used to determine whether the user has
been registered. The current face is registered
when the similarity between the
acquired facial image and all registered facial templates is greater than the set value.
Pitch angle threshold
To limit the pitch angle of face in face recognition, the recommended threshold is 20.
Rotation angle
threshold
To limit the rotation angle of face in face recognition, the recommended threshold is
20.
Image Quality
To get the quality threshold of facial images. When the value of image quality is
greater than the set value, the device will accept the facial images and start the
algorithm processing, otherwise, the device will filter the facial images out.
Threshold of turning
on the supplement
LED
Detect ambient
light intensity. When the ambient brightness is less than the
threshold, the fill light is turned on; When ambient brightness is greater than this
threshold, the fill light does not turn on. The default value is 80.
Alive body detection
switch
If
enabled, it will automatically detect whether there is a moving person in front of
the device.
Alive body detection
threshold
Detect whether there is a moving person in front of the device to determine whether
face recognition is enabled. The default value is 100. The valid value ranges from 0 to
100.
Notes
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.
