The video surveillance systems night vision takes advantage of the infrared light, which has a frequency not visible to the human eye and guarantee a better result than the white light. The majority of CCTV cameras has integrated LEDs but they allow only a partial environment enlightenment producing a light cone that comes out from the camera. The IR Illuminators are useful to enlighten better the surrounding environment and expanding the light cone coming from the camera. A better brightness in night conditions means a better and sharper cameras’ recording.
