The 6mm F/1.8 1/3" CS-Mount IR Lens is designed to provide infrared night vision for distances of up to 10 meters (32.8 ft.) for compatible cameras with a CS lens mount. The lens offers a 56 degree viewing angle, 6mm focal length, equivalent 1.8 F/No and a manually adjustable focus. A light sensor built into the lens automatically triggers the infrared bulbs in low light conditions. No additional power source is required for this lens. A built-in Y-shaped power cord, powers both the camera and the lens by plugging directly into the compatible camera's power port.
