Dahua HDCVI Dahua Technology presents High Definition Composite Video Interface (HDCVI) technology to the market. HDCVI, Dahua's in-house technology, is an over-coaxial-cable analog HD video transmission standard, allowing long-distance HD transmission at a lower cost to meet the requirements for a complex and large installation.

HDCVI is a solution for megapixel high definition applications, featuring non-latent long-distance transmission at a lower cost. The name has to do with its baseband and quadrature amplitude modulation technology, which is able to avoid CVBS cross talk, completely separate brightness and hue signal, and further enhances video quality.

The HDCVI solution incorporates both cameras and DVRs.
