1080p HD-CVI PTZ! This Pan Tilt Zoom camera has a 20X Optical Zoom Lens and the detail is incredible. You will need to connect this security camera to a 1080p HD-CVI DVR, or one of our Tribrids, in order to use it. HD-CVI is a newer security camera technology that enables High Definition video to be transmitted over standard coax cable. One major benefit to HD-CVI is that video, audio, and control of the PTZ and OSD (On screen Display) is all transmitted through the same RG59 Video Cable. This means that their are no extra wires to fumble with when installing this camera.
