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.
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..
