Night vision Camera
The most common type that’s used on most security cameras is infrared (IR) night vision, which relies on infrared light. The thing is, infrared light is completely invisible to the naked eye. So it doesn’t look like a bright light is flooding the area from the outside, but it actually is—your eyes just can’t see it IR or night vision cameras use infrared light to illuminate images in the dark. Infrared light is actually all around us.
