Infrared security cameras have the capability to capture video in low light and no light (0 Lux) areas. Infrared cameras (IR) are sometimes referred to as IR cameras or "Night Vision Security Cameras" because of this. Infrared cameras have IR LEDs positioned around the outer edges of the camera lens which gives the camera its "Night Vision".
