The Smart IR function is more benecial 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 eectively 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 signicant
benets as in close range.
