3.0 INSTALLATION
The camera and lens package are installed at the factory.

3.1 ADJUSTMENTS

Your optics package comes from the factory adjusted for a broad range of lighting
conditions. For this reason, you may find it necessary to adjust your optics package
to tailor the picture to your specific viewing environment. The following adjustments
can be made to the Pelco optics package.
•Back focus • White balance (color only)
•Shutter speed • V-Phase (Vertical Phase)
•AGC • Auto iris level (certain models only)
The factory adjustments for the above controls are set as follows:
➤Back Focus
Adjusted with focus far/zoom wide looking at an object 55 feet (16.76 m) from
the lens. The results are a clear, in-focus picture through the entire zoom range
(reference Figure 1 for back focus adjustment location).
➤Shutter Speed
Factory set to the slowest speed available: 1/60 second.
➤Auto Gain Control
AGC ON/OFF set to ON.
➤White Balance
White balance has two positions; one is ATW (Automatic Tracing White), which
is a feature that continuously adjusts the camera for optimum color reproduc-
tion. AWB (Automatic White Balance) is a feature that retains current settings
in memory even when the power is off.
➤V-Phase (Vertical Phase)
See section 3.1.5.
