single, unchanging primary light source.
Day Mode Setting:
Exposure Value: Select a proper exposure value from 0 to 255 (dark to bright).
Exposure Time: Select a proper exposure time depending on the light source of
the surroundings. Decreasing Max Exposure Time reduces the blur caused by
fast moving objects as the light dims, but it also reduces the light sensitivity of
the camera. The exposure times are selectable from 1/15 to 1/10000 sec.
Gain: Increasing the gain increases the brightness of the image, but it also
increases the amount of noise in the image. The gain ranges from 00 to 08
