CAMERA SETTING

¾ 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.

¾ 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.

The default setting is ON.

¾ FL (Flickerless)

When picture flicker fiercely, turn FL on, then the camera will stabilize the speed of electronic

shutter at 1/100(S)(NTSC) or 1/120(S)(PAL) automatically, and reduce the flicker immediately.

The default setting is OFF.

¾IRIS Level Control (For Vari-Focal Lens Model)

Brightness Level can be adjusted from the IRIS level VR while using the direct drive lens.
