Smart IR
When enabled, the camera automatically adjusts the IR projection to adjacent objects in order to
avoid over-exposure in the night mode.
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.
