gasket or sealant around the conduit connection.

4. Wire Connection

The camera comes with a conduit plug

pre-installed in the PF 1/2 conduit entry on

the side. The screw can be removed and

Termination Board

Connect the power supply cable (12VDC/24VAC), video output and alarm

output to the proper connectors shown as Figure 5.

The V. Phase adjustment screw is located on the termination board. The

vertical phase may require adjustment to synchronize the vertical phase of the

camera with other camera in the system when it is to be used in the line-lock

sync mode. Make the adjustment when the vertical phase of the camera does

not match with other cameras.

5. View Angle Adjustment

The camera can be rotated 360° horizontally, 140°vertically and 60° 3’rd axis

view angles (as shown in Figure 6). Adjust the proper camera view angle as

needed. If a vari-focal lens is used, you may adjust the focus and zoom of

the lens to bring the object in focus. Be sure to loosen the locking screws on

the lens before you make adjustment.

DIPSWITCH 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.
