5. Control Switches
There are 6 control switches located on the sideboard, which are for the setting
of the special features. The switches in orders are for Flickerless, Back Light
Compensation, Electronic Shutter, Automatic Gain Control, Line-Lock and Auto
Iris Lens type.
FL (Flickerless Function) On/Normal
When picture flicker fiercely, turn FL on, then the camera will stabilize the speed
of electronic shutter at 1/100(EIA) or 1/120(CCIR) automatically, and reduce the
flicker immediately. The default setting is Normal.
BLC (Back Light Compensation) On/Normal
When BLC is turned on, the AGC, ES 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-lit. The
default setting is Normal.
ES (Electronic Shutter) Off/On
ES ON: The camera continuously adjusts the shutter speed from 1/60 (EIA),
1/50(CCIR) second to 1/100,000 second according to the luminance conditions
of the scene.
ES OFF: The shutter speed is fixed at 1/60 (EIA), 1/50 (CCIR) second.
Set ES OFF, when auto iris lens is used or flicker is observed under a very bright
fluorescent lamp. Otherwise, turn ES on for optimum performance. The default
setting is ON.
AGC (Automatic Gain Control) Off/On
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.
LL (Line-Lock) Off/On
To select the sync mode between Internal Sync.(LL off) and Line-Lock (LL on).
Set the line-lock off, the camera will synchronize to the internal time base.
Set the line-lock on, the camera’s vertical synchronization can be driven bythe
AC signal in the power lines.
Note: Line-Lock sync mode operation is possible only when used with an AC
power source; it’s not possible with a DC power source.
VD/DD (Auto Iris lens Type)
For video drive auto iris lens, please set switch to VD. For direct drive iris lens,
set switch to DD. The default setting is DD. Wire the cable of lens to lens
connector according to the following table.
