The DS-2CD2047G1-L from Hikvision is a 4 Megapixel Network IR Outdoor Bullet Camera, 2.8mm Lens. Hikvision ColorVu technology provides 24/7 vivid colorful images with F1.0 advanced lenses, high performance sensors and friendly lighting. F1.0 super-aperture collects more light to produce brighter images. Advanced sensor technology can vastly improve the utilization of available light.
