IMPORTANT:
The minimum Plug the connector from the lens into the auto iris jack on the
back of the camera. The connector is polarized and can only be inserted into the jack one
way.
3. Apply power to the camera.
4. The OSD AE menu in the lens select should be in the “VIDEO”.
5. Adjust the focus ring on the lens for an optimum picture. If a picture is not visible, set the
lens for proper exposure by adjusting the ALC (Automatic Level Control) and the level on the
lens. The ALC setting can range between AVG (average) or PK (peak). A midrange 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.
6. Set the back focus of the camera before the final adjustment of the video level.
7. 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.
