Wide Dynamic Range (WDR)
Images with WDR are produced by combining long-exposure
signals(normal shutter) with the signal of the high-intensity
portions obtained a short-exposure (high-speed shutter).
(NOTE1) When CVBS is connected, WDR automatically turns off and
Digital WDR operates.

High-Light Compensation (HLC)
It's ability to reverse bright points in the picture to black. As an
effective approach to recognize vehicle plate number at night,
HLC function can detect any spotlight diffused by object-
vehicle and compensate it for obtaining clearer image.
Spot AE
• Available in Full Auto AE mode.
• A particular section of the subject can be designated, and
then that portion of the image can be weighted and a
value computed so that iris and gain can be optimized to
obtain an image.
