Dahua Technology, a provider in the security and surveillance field, published HDCVI (High Definition Composite Video Interface), a newest transmission standard with own intellectual property rights. Being an independent innovative analog HD video transmission technology over coaxial cable, HDCVI is perfectly designed to satisfy surveillance requirement. HDCVI has an over 500m reliable HD million pixel video transmission distance to break through the distance limit of existing technology. As an emerging force in the developing process of video surveillance, HDCVI will accelerate the popularization of high definition video security system.
HDCVI is an analog high definition video transmission standard over coaxial cable. It uses progressive scanning and supports two high definition video formats of 1280H and 1920H (1280H is defined as 1280×720 effective resolution; 1920H is defined as 1920×1080 effective resolution). By transmitting uncompressed and lossless signal over point-to-point links, HDCVI is a reliable, none delay, high efficiency and million pixel video transmission technology. HDCVI provide a reliable transmission distance of more than 500m over 75-3 or similar coaxial cable by adaptive corrections of signal loss. In addition, HDCVI owns several independent intellectual property rights, including composite audio signal transmission technology and bi-direction data communication technology.
HDCVI technology, which satisfies the multiple requirements of market and combines breakthrough innovation and practical application advantages, gives great commercial value in high definition era. Further, HDCVI will become the video surveillance direction and bring a new industry standard.
