ES (Electronic Shutter) Off/On
ES ON: The camera continuously adjusts the shutter speed from 1/60
(NTSC),1/50 (PAL) second to 1/100,000 second according to the
luminance conditions of the scene.
ES OFF: The shutter speed is fixed at 1/60 (NTSC), 1/50 (PAL)
second. Place ES in the off position, when auto iris lens are used or
flicker is observed under extremely bright fluorescent lighting. In all
other lighting, keep ES in the on position 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
Use this switch to select the sync mode between Internal Sync.(LL
off) and Line-Lock (LL on). To synchronize the camera to the
internal time base, set the line-lock in the off position. By setting the
line-lock on, the camera’s vertical synchronization can be driven by
the AC signal in the power lines.
Note: The cameras feature AC line lock for external
synchronization. Using the AC power frequency (60Hz) is
possible but not available when using DC or other
operation power such as NTSC in 50Hz or PAL in 60Hz
power system.
