FLICKERLESS
In some installations, the cycle of the fluorescent lights may interfere with the electronic iris shutter speed. Use this option to override the
shutter speed. When enabled, the shutter speed is set to 1/100 (NTSC) or 1/120 (PAL).
Select ON or OFF. The default setting is OFF.
NOTE: This option appears when AUTO EXPOSURE is set to NORMAL or BLC.
AUTOMATIC GAIN CONTROL
Automatic gain control (AGC) automatically adjusts the image when the light level changes. Most scenes benefit from AGC operation.
Select ON or OFF. The default setting is ON.
NOTE: You can also use the side panel button to enable or disable AGC.
