Eclipser Function (NTSC/EIA Models Only)
The eclipser function is used with an auto iris lens. When using a CCD imager with an auto iris
lens in an area with minimal lighting contrasts, the auto iris lens closes, resulting in poor
picture quality. The eclipser function distorts the signal to the auto iris lens, causing the lens to
open wider and create sufficient lighting contrasts to prevent the silhouetting of figures. The
eclipser function switch can be turned ON/OFF by moving the ECLP switch right or left. The
ECLP is factory set to the OFF position. When the auto iris lens used is equipped with a
response selector (AVERAGE/PEAK), always set the selector to AVERAGE.
