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, the Smart IR function may not bring as significant benefits as in
close range�
Smart IR
When enabled, the camera automatically adjust the IR projection to adjacent objects in order to
avoid over-exposure in the night mode�
