2.2.3.2 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.
Manual
Manual is a mode that allows the user to manually control both gain value and shutter speed. Selecting a smaller value
like 1/10000 provides the fastest shutter speed and vice versa. The larger the value, the more intensity of lights come into
the camera and vice versa. It is recommended for an experienced administrator to adopt this mode.
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
