VI. Adjusting the Camera Image

Camera Lens Close-up View

1. While viewing the camera image through the Video Management System (VMS)

camera image window, adjustments can be made to the camera’s zoom, iris or

focus.

2. Open the camera housing using the safety latch at the rear of the unit. The

camera imager is located just behind the glass housing window.

2.1 To adjust focal length (zoom), loosen the focal length locking knob counter-

clockwise. Rotate the focal length adjustment ring at the rear of the lens (the

ring, not the knob) to adjust.

2.2 To adjust iris, turn the iris lock knob counter-clockwise to release. Slide the

iris locking knob to the right or left to set. (The “O” open setting is best for

achieving good low light camera performance.)

2.3 To focus, turn the focus lock knob counter-clockwise to unlock. Rotate the

focus adjustment ring at the front of the lens to adjust.

Typically both focus and zoom will need to be adjusted at the same time to

achieve the desired field of view. Lock knobs need only be lightly tightened

to hold the lens settings in place.

2.4 After the imager adjustments have been completed, close the camera

housing and lock the latch into place.

After this step, setup is complete and the wireless camera is ready for use.
