DIP SWITCH FUNCTION

¾BLC (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.

¾AGC (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.

¾FL (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. •Turn counterclockwise to L to get darker picture.

•Turn clockwise to H to get brighter picture.¾Electronic Shutter (For Fixed Lens Model)

ES ON: The camera continuously adjusts the shutter speed from 1/60 (NTSC), 1/50 (PAL) second to 1/100,000 second according to the luminance conditions of the scene.

ES OFF: The shutter speed is fixed at 1/60 (NTSC),1/50 (PAL) second.

Set ES OFF, when auto iris lens is used or flicker is observed under a very bright fluorescent lamp. Otherwise, turn ES on for optimum performance.
