IR Function
With the IR cut filter, the Dome Camera can still catch clear image at night time or in the very dark
light condition. During day time, the IR cut filter will be on to block the infrared light for clear image;
during night time or in dark light condition, the IR cut filter will be removed to catch infrared light, and
the displayed images will become black and white.
AUTO
The Internal circuit will automatically decide the occasion to remove the IR cut filter according
to the value of light condition calculated by the internal light algorithm. The options include
<LOW>, <MID> and <HI>. <LOW> indicates a higher sensitivity and can improve reliability of
lens so that it is easier to switch to Day mode and relatively difficult to change into Night
mode; while <HI> indicates that it is easier to switch to Night mode and difficult to change into
Day mode.

Set this item to <ON>; the center object will be brightened in contrast to the edge of the picture
(where backlight would most likely be located).
