Installation  Instructions

INSTALLING VIDEO DRIVE LENSES

6. With typical scene illumination, set the Lens Level adjustment potentiometer for the correct

exposure. This can be done visually. More accurate results will be achieved using a video

level meter or oscilloscope to set the output of the camera to 1V peak-peak.

7. If the scene lighting conditions are extremely uneven, it may be necessary to adjust the

lens’s Peak Average potentiometer. Refer to the lens instructions.

8. Ensure the Automatic Gain Control (AGC) features is turned ON.

CAMERA MOUNTING

Mounting points are provided on the top and bottom of the camera and are used to mount the

camera on a bracket or tripod. They are designed to accept standard photographic mounting

bolts (1/4" BSW or 20 UNC). The mounting bracket must be capable of supporting the weight of

the camera 

and 

its lens. In cases where the lens is substantially heavier than the camera, it is

better to use the mounting point on the lens itself.
NOTE: Some installation codes dictate that the mounting bracket must be capable of supporting

up to four times the combined weight of the camera and lens.
The mounting bracket is not evaluated by UL..
