Caution for Mounting the Lens

The lens mount should be a C-mount or CS-mount (1”-32UN) and the lens weight should be less than 450 g (0.99 lbs). If the lens is heavier, both the lens and camera should be secured by using the supporter.

The protrusion at the rear of the lens should be as shown below:

C-mount: Less than 13 mm (1/2”)

CS-mount: Less than 8 mm (5/16”)

The following adjustment should be made by qualified service personnel or system installers.

1.Loosen the screw on the side of the camera.

2.Turn the flange-back adjusting ring to the desired position.

Caution: When the C-mount lens is mounted, do not rotate the ring counterclockwise by force after it stops. If the ring is rotated by force, the inner lens or CCD image sensor may be damaged.

3.Tighten the screw on the side of the camera.

INSTALLATION OF CAMERA

•Mounting from the top

Remove the mount adapter from the bottom of the camera by removing the two fixing screws. Attach the mount adapter to the top as shown in the diagram, then mount the camera on the mounting bracket.
