Menu Item Description
Exposure This parameter is used to set the exposure value of the camera.
Quality
This parameter is used to set a quality threshold for the facial images obtained. The FFR
terminal accepts the facial images and processes them by adopting the facial algorithm
when their quality is higher than the threshold; otherwise, it filters these facial images.
Note:
Improper adjustment of the
Exposure

Quality
parameters may severely affect the
performance of the device. Please adjust the Exposure and Quality parameter only under the
guidance of after-sales service personnel from our company.
