IR illuminators
The IR (Infrared lilght) related functions are available for the FE9391-EV.
Anti-overexposure disabled; distance: 5M
Anti-overexposure enabled; distance: 5M
Anti-overexposure disabled; distance: 3M
Anti-overexposure enabled; distance: 3M
The 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 close range.
Anti-overexposure
When enabled, the camera automatically adjusts the IR projection to adjacent objects in order to avoid
over-exposure in the night mode.
