The DS-2CE56D7T-IT3-6MM from Hikvision is a HD 1080p WDR EXIR outdoor turret camera, 6mm lens. The Hikvision DS-2CE56D7T-IT3 turret camera provides high definition analog output up to 1080p. TurboHD means that the analog signal can be sent over existing RG6 coaxial cable, eliminating the need to run new cables for high definition video.
