BACKLIGHT COMPENSATION

Backlight compensation controls iris

gain and white balance

simultaneously. If you have objects

in the foreground that appear

silhouetted in front of a brighter

background, set backlight

compensation to on. The

foreground objects appear with

greater definition.

Note: Compensation might be insufficient when the background is extremely bright.

To set backlight compensation see Figure 13 perform the following.

• To set backlight compensation on, ensure that the jumper is

securely in place.

• To set backlight compensation off, remove the jumper.

VERTICAL PHASE

CAUTION:

The phase adjustment must be made by a qualified service person

or installer.

The vertical phase of the camera video signal can be synchronized to the

phase of the AC power line by using a dual-trace oscilloscope to observe

the video output signal (V-rate) of the camera and by adjusting the phase

control buttons (see Figure 13) to line up the phases of both signals or by

using a KTS-56 V-Phase Adjustment Tool.
