CAMERA ADJUSTMENT
Camera Position
The camera assembly is adjustable in all three axes (figure 7). Adjust the camera until it is pointing in the
desired direction.
Field of View and Focus
Use the levers on the varifocal lens to adjust the camera’s field of view (1, figure 8), and focus (2, figure 8).
SWITCH SETTINGS
The DIP switches are located on the camera’s circuit board (2, figure 9).
Backlight Compensation
The Backlight Compensation (BLC) feature compensates for back-lit scenes by enhancing objects in the centre
of the scene which would previously have been in silhouette. Select ON or OFF using the BLC switch. Default
is OFF.
Automatic Gain Control
The Automatic Gain Control (AGC) feature can improve picture quality when levels of illumination are low.
Select ON or OFF using the AGC switch. For most applications the AGC feature should be ON and is therefore
the default setting.
Electronic Iris
The Electronic Iris (EI) feature compensates for excessive light levels by automatically adjusting the shutter
speed. For auto-iris lenses, the EI should be set to OFF. For manual lenses, EI should be ON.
Line Lock
Choose INT (internal) or LL (adjustable). The LL setting allows ±180
O
phase adjustment via the two LL Phase
Advance/Retard buttons (3 and 4, figure 9). Default is LL. Pressing both buttons simultaneously will reset LL to
the factory default setting. For the ICED-B3H39 camera, LL is adjusted using the LL potentiometer (5, figure 9)
