Infrared (IR) technology in video surveillance refers to the use of IR light to illuminate dark areas, enabling cameras to capture clear images and footage in low-light or complete darkness. IR cameras, also known as night-vision cameras, are equipped with IR LEDs that emit IR light, which the camera's sensor can detect and process into a clear, black-and-white image, enhancing security by providing effective surveillance even during nighttime or low-light conditions.
