The Hikvision DS-2CE78D3T-IT3F-6mm 2 MP Outdoor Ultra-Low Light Turret Camera provides high definition analog output. TurboHD means that the analog signal can be sent over existing coaxial cable, eliminating the need to run new cables for high definition video. EXIR 2.0 is Hikvision’s proprietary IR extended range technology, which has a range of 165 feet (50 meters). The 6 mm lens option is optimized for viewing angles that fit any situation. True 120db WDR (Wide Dynamic Range) ensures that ideal images are captured regardless of the lighting conditions.
