4 Signals over 1 Coaxial Cable
HDCVI technology can simultaneously transmit 4 signals (audio, video, data, and power) over 1 coaxial cable. HDCVI cameras offer high resolution video, support audio input or built-in mic, and communicate with the HCVR through control signals. Moreover, Power-over-Coax (PoC) technology has been made available for integrated power-supply requirements. HDCVI cameras are able to cover multiple signal acquisitiondemands, further simplifying the installation and deployment of surveillance systems.

HDCVI technology guarantees long-distance transmission in real-time without any signal loss. Based on real-world scenario testing in Dahua's test laboratory, it supports the following distances at the corresponding resolutions.
