Turn on built-in IR illuminator in night mode
By default, the built-in IR illuminators are turned on when the camera detects low light condition
and enters the night mode.

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 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 signicant benets as in
the 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.
