The Smart IR 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, Smart IR can effectively reduce the over-exposure. For a surveillance area at a
greater distance, e.g., 5 meters or farther away, the Smart 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.
