HD-CVI surveillance cameras rival Network IP and HD-SDI while costing about the same as an analog CCTV system. They offer a resolution up to 1080p and can transmit uncompressed video up to 1500 feet. HD-CVI security cameras only need one cable for video, audio and pan/tilt/zoom and are compatible with a variety of cables including coaxial cable and Ethernet. These surveillance cameras will need to be used with HD-CVI DVRs for recording footage but the overall cost is usually less than Network IP systems. Power is supplied by 12V DC or 24V AC.
