The 1080p HD-CVI PTZs are here! Now you can get 2MP High Definition 1080p recording from a Pan Tilt Zoom camera at an affordable price. The great benefit of an HD-CVI PTZ is that all video, audio, and control of the PTZ goes through the same RG59 cable. This way, there are no extra wires to run for control or for connecting a microphone. HD-CVI technology works over standard coax cable so if you are upgrading from an analog system to HD, you can leave your cable and power in place and just replace your DVR with an HDCVI DVR and swap out your cameras.
