To increase the speed of the lens reaction to the changing light, set the lens

adjustment to PK so the lens will adjust to the brightest or peak object in the

video. Use this setting if you want to see the brightest object and not the

background objects.

For Level adjustments:

Adjust the level control for the best picture during the day. A night adjustment may not

provide the proper setting for controlling the light during the day.

8. Set the back focus of the camera before the final adjustment of the video level.

9. If the auto iris has a gain adjustment and the picture oscillates between open and closed

under bright lights, slowly turn the gain adjustment counter clockwise until the oscillating

stops. Increase the light getting to the camera by adjusting the level control and

re-adjusting the gain control.
