b. Zoom and focus adjustments (For Vari-focal Lens Model)
After the camera was installed, the zoom and focus of the lens must be adjusted.
(1) Loosen the zoom ring knob, and then turn the ring towards <W> or <T> as necessary to
obtain the desired view range.
W side (Zoom out)
The viewing range will be wider and the subject is smaller.
T side (Zoom in)
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.
(3) Repeat steps 1 and 2 until the best image is obtained.
Once the lens setting finished, tighten the zoom ring and the focus ring knobs.
CAMERA SETTING ¾ 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.
¾ 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.
The default setting is ON.
