Exposure time and Gain Control to the best image quality� A shorter exposure time allows less amount
of light to enter the sensor; while a higher gain control value generates certain amount of noises�
Auto: If you set Exposure mode as Auto, the Exposure time and Gain control will be not configurable
since the sensor library will automatically adjust the value according to the ambient light� Then you can
set iris mode as "indoor" or "outdoor" to reach the best image quality�
