Gain control slider
Appears when you choose
Manual
from the Exposure mode drop-down menu.
To control the minimum gain of the IP camera, drag the left slider box. To
control the maximum gain, drag the right slider box. A value of 0 does not
boost the gain, so the image may appear darker in a darker environment. A
higher value increases the exposure of the image, which can cause the image
to look brighter, but can also cause the image to appear more noisy.
When capturing video, the IP camera automatically selects the optimum value
between the minimum and maximum values that you configure.
