The Hikvision ECT-T12x Outdoor EXIR 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 65 feet (20 meters). The 2.8 mm, 3.6 mm, and 6 mm fixed lens options are optimized for viewing angles that fit any situation.
