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

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.
