Exposure : This parameter is used to set the exposure value of the camera.
Gain : This parameter is used to set the gain value of the camera.
Quality : This parameter is used to set a quality threshold for the facial images
obtained. The 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.
Algorithm Version: Face Algorithm can choose 5.0Algorithm or 7.0Algorithm.
Note: Improper adjustment of the Exposure, Gain and Quality
parameters may severely affect the performance of the terminal. Please
adjust the Exposure parameter only under the guidance of the
after­sales service personnel from our company.
