The anti-overexposure function is more beneficial when the spot of intrusions or an object of your
interest is close to the lens and the IR lights. For example, if an intruder has a chance of getting
near the range of 3 meters, the anti-overexposure can effectively reduce the over-exposure. For a
surveillance area at a greater distance, e.g., 5 meters or farther away, the IR function may not bring
as significant benefits as in close range.
Anti-overexposure : When enabled, the camera automatically adjusts the IR projection to adjacent
objects in order to avoid over-exposure in the night mode.
