  • New HD-Over-Coax Solution Provides Long-Distance Transmission..........

    As the industry moves from standard definition to high definition, how can we ensure the whole surveillance system not only satisfies the resolution requirement, but also the total cost? 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.

    Analog systems, based on coaxial cabling, still dominate today’s video surveillance market — there are approximately 400 million analog cameras in use throughout the world. The demand for high definition from end-users is undoubtedly increasing; however, the need to change the cabling for a HD system can result in higher operational costs. With no new cabling or IP hassle required, HDCVI is one option for upgrading existing systems from standard definition to high definition, offering longer transmission via coaxial cable and lower total cost.

    What is HDCVI?
    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. The system is star topology structured — the DVR serves as a node for an over coax P2P (Point-to-Point) transmission to the camera. The technology offers two specifications: 1080p (1920×1080) and 720p (1280×720). In addition, the technology features the Auto Signal Compensation (ASC) patent, which only allows an extremely low signal distortion along long-distance transmissions.

    Long-distance Transmission
    Transmitting data over 500m over a coaxial cable can be realized, depending on the cable selected. Cable 75-3 and 75-5 are recommended for transmissions within 500m, cable 75-5 and above for over 500m. Connectors and welding process also affect the transmission distance.
    3 Signals in 1 Coaxial Cable

    HDCVI composites video, audio, and control signals together and then transmits them over one coaxial cable, simplifying the installation.
