The anti-overexposure function is more benecial 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 signicant benets 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.
