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.
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.
