According to Dahua, HDCVI is the technology breakthrough of the industry, offering a fast and easy upgrade to high definition under a conventional cabling environment with advanced features.

HDCVI technology will easily upgrade to HD. It renders 1080p & 720p HD video format by analogue modulation; which means that the new solution provides the exact same installation and deployment as a conventional analogue system, but in addition also offers megapixel high video quality with more details retained.

It supports long-distance transmission. Due to the fact that it is transmitted over-coax, HDCVI is able to achieve reliable long range and non-latent transmission without further relay devices. For comparison with HD-SDI at the transmission end, HDCVI shows a distinct advantage. With general transmission media, HD-SDI reaches 100 metres at most while HDCVI transmits at least 500 metres by using 75-3 cable and featuring a low signal distortion rate.

HDCVI is also more reliable as it adopts P2P transmission. Meanwhile, it features no latency for an outstanding real-time performance and it requires no compression, which successfully maintains the original quality and thus presents vivid images.

In addition, it can carry three signals — composite video, audio and control — over one single cable; Dahua's HDCVI solution could further simplify cabling whilst ensuring a smooth transmission at the same time.

In summary, Dahua believes that HDCVI is an industrial breakthrough, a revolutionary technology that offers megapixel image quality over long-distance transmission while enjoying the simplest installation requirements.
