Rear View of CC3300 Series Cameras
2.1.2 Rear (Illustration B )
IRIS LEVEL L/H adjustment pot
This pot can be used to adjust the incident light level
when using the CCD iris or a DC servo lens. Before
leaving the factory, the level is set for the CCD IRIS.
If you wish to use a DC servo lens, turn the adjust-
ment screw towards the H (high) side.
V PHASE (vertical phase) ± adjustment pot
Use this pot to compensate for vertical phase dis-
crepancies which can occur when multiple cameras
are connected to a switching device. Each camera’s
output is synchronized to the frequency of the power
supply.
AGC (automatic gain control) ON/OFF switch
When the AGC is switched on, the signal sensitiv-
ity automatically adjusts to the lighting conditions
of the subject. The switch normally remains in the
AGC position.
Turbo-AGC TURBO/NORM switch
When switched to TURBO, the Turbo-AGC func-
tion gives you a brighter picture under poor light-
ing conditions. Although noise increases slightly,
signal elements are nearly doubled, thereby increas-
ing picture definition. Switching this function on
also activates the AGC function.
BLC compensation ON/OFF switch
Set the BLC (backlight compensation) switch to
BLC to compensate for scenes with a strong back
light. The BLC function senses the strength of the
back light and compensates accordingly. Switch-
ing this function on also activates the AGC func-
tion.
CCD IRIS ON/OFF switch
When switched on (switched to CCD IRIS) this
function automatically adjusts the sensitivity in ac-
cordance with the incident light conditions. Set this
switch to OFF when using an auto-iris lens. The
factory setting is CCD IRIS.
VIDEO OUT connector
This coaxial connector (BNC-type) outputs the
video signals.
GND (ground) terminal (CC3300-2, -2X only)
Connect this terminal to ground.
24 VAC 1 and 2 terminals (CC3300-2, -2X only)
Connect these terminals to a 24 VAC, 50/60 Hz
power supply.
Main Power Cable lead (CC3300-3 only)
Connect to a 220-240 VAC, 50 Hz power supply.
