Set the smart IR to ON, and Auto and Manual are selectable for IR mode. Select AUTO, and

the IR LED changes according to the actual luminance. E.g.: if the current scene is bright

enough, then the IR LED adjusts itself to lower power; and if the scene is not bright enough,

the IR LED adjusts itself to higher power.

Select Manual, and you can adjust the IR LED by adjusting the distance. E.g.: If the object is

near the camera, the device adjusts the IR LED to lower power, and the IR LED is in higher

power if the object is far.
