Smart IR
Auto IR adjust
The Smart IR 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, 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 significant benefits as in close
range.
