5
PK (peak). A mid-range setting is appropriate for most
applications.
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.
F) Set the back focus of the camera before the final adjustment
of the video level.
G) If the auto iris has a gain adjustment:
1. If the lens oscillates between open and closed under
bright lights, slowly turn the gain adjustment counter
clockwise until the oscillating stops.
2. Increase the light getting to the camera by adjusting the
level control and re-adjusting the gain control as
necessary.
3. Reset the level control as noted in step E.
