3.2.3.2 Exposure
Exposure is the amount of light detected by the camera sensor. A scene with correct exposure settings has adequate detail
and contrast between white and dark values. An image with too little or too much exposure eliminates detail in the scene. The
camera features Exposure and Day/ Night settings.

Exposure
Priority Preset
Select Motion or Low Noise as the exposure priority. The Motion setting increases exposure time to reduce motion
blurring in low light. The Low Noise setting decreases exposure time and adjusts frame rate for improved noise reduction
in low light scenes.
Flicker Correction
Flickering by fluorescent light can be reduced by selecting “50Hz” if the power frequency is 50Hz, “60Hz”, if 60Hz.
Basic Setting
BLC
Select an area ranging from Upper, Lower, Central 1/3rd, Central 1/6th, Left, and Right for Backlight Compensation.
Backlight Compensation is a function that sets the brightness of a selected area to an optimal level. This function is
necessary when an auto iris lens tends to close quickly due to an intense light coming from the back of object in the area
wished to view, resulting in the area being too dark and difficult to see. In this case, users may set the area
corresponding to the portion they wish to see.
Digital WDR
Select On to enable Digital WDR. This feature is intended for providing clear images even under backlight where intensity
of illumination can vary excessively, i.e. when both very bright and dark areas simultaneously come in the field of view.
Digital WDR, via software algorithm, enables capture and display of both bright and dark areas in the same frame, in
such a way that there are clear details in both areas, i.e. bright areas are not saturated and dark areas are not too dark.
