After the camera was installed, the zoom and focus of the lens must be adjusted.

obtain the desired view range.

The viewing range will be wider and the subject is smaller.

The viewing range will be smaller and the subject is larger.
(2) Loosen the focus ring knob, then turn the ring towards <∞> or <N> as necessary to
obtain the clear video image.

Once the lens setting finished, tighten the zoom ring and the focus ring knobs.
CAMERA SETTING
BLC (Back Light Compensation)
When BLC is turned on, the AGC, FL and IRIS operating point is determined by averaging over
the center area instead of entire field-of-view, so that a dimly-lit foreground object at center area
can be clearly distinguished from brightly-lit backgrounds. BLC should not be used unless it is
needed to compensate for back-light.
The default setting is OFF. For Auto-Iris lens model, the brightness can also be adjusted via the
Iris level control VR.
AGC (Automatic Gain Control)
AGC ON: The sensitivity increases automatically when light is low.
AGC OFF: A-low-noise picture is obtained under a low light condition.
