  • HDCVI Technology, High Resolution World


    HD-CVI is on the technical base of Dahua Technology Co., Ltd.,being a new technology which is own research, enable to reliably transmit super long-distance HD video signal through low-costs and low-quality coaxial cable. It uses baseband modulation an d quadrature amplitude modulation, modulating video to the analog electrical signal then transmitting,so named HD-CVI.

    The technology own several obvious advantages as bellowing :

  • HD-CVI Camera can transmit HD video with 720P and 1080P effective resolution . Through SYV75-3 coaxial cable it enable to tra nsmit at least 500m,with low signal distortion ;
  • HD-CVI Camera use low-frequency analog modulation technology. It avoids interference of high-frequency wireless electromagn etic radiation from the nature of the technical principles . Even under strong-interference sources environment ,HD-CVI ensure to tran smit high-quality image .
  • HD-CVI Technology keep the analog SD construction requirements and cabling specifications . Ordinary weak construction worker s can quickly deploy HD monitor subsystem.
  • Current analog SD devices upgrade can seamlessly switch to HDCVI products . By replacing the camera and DVR to realize the full HD monitoring requirements.
  • HD-CVI system keep the same using method as SD system . Analog camera plus DVR deploy inner system equipments to achie ve plug and play, based on DVR interoperation
