Dc Auto Iris Lens Installation & Adjustment - Hitron HCB-F9 Instruction Manual

For ALC adjustments:
AVG To slow the reaction of the lens to changing light, set the range to
the AVG setting to average the video level from the camera.
Use when there are bright spots in the picture such as lights or
glare from the sun.
PK 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.
7. Set the back focus of the camera before the final adjustment of the video
level.
8. 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.
