An IR (Infrared) illuminator is a device that projects near-infrared light, which is invisible to the human eye but visible to security cameras and night-vision equipment. Acting as a “covert flashlight,” it enhances visibility in low-light or total darkness, commonly used in surveillance (CCTV), wildlife observation, and tactical gear.
