5.Control Switches

There are 6 control switches located on the sideboard, which are for the setting of the special features. The switches in orders are for Flickerless, Back Light Compensation, Electronic Shutter, Automatic Gain Control, Line-Lock and Auto Iris Lens type.

FL (Flickerless Function) On/Normal

When picture flicker fiercely, turn FL on, then the camera will stabilize the speed of electronic shutter at 1/100(EIA) or 1/120(CCIR) automatically, and reduce the flicker immediately. The default setting is Normal.

BLC (Back Light Compensation) On/Normal

When BLC is turned on, the AGC, ES 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-lit. The default setting is Normal.
