BLC (Back Light Compensation)
When BLC is turned on, the AGC, FL and IRIS operating point is determined by averaging over
the center area instead of entire field-of-view, so that a dimly-lit foreground object at center area
can be clearly distinguished from brightly-lit backgrounds. BLC should not be used unless it is
needed to compensate for back-light.
The default setting is OFF
. For Auto-Iris lens model, the brightness can also be adjusted via the
Iris level control VR.

AGC (Automatic Gain Control)
AGC ON: The sensitivity increases automatically when light is low.
AGC OFF: A-low-noise picture is obtained under a low light condition.
