What is a CVI camera? Is it the kind of camera we commonly use?

HDCVI high-definition composite video high-definition camera is a high-definition video transmission specification based on coaxial cable, which uses analog modulation technology to transmit progressive scan high-definition video.

HDCVI technology uses adaptive technology with independent intellectual property rights to ensure the transmission of high-quality high-definition video at least 500 meters over coaxial cables with specifications of 75-3 and above, breaking through the existing transmission technology of high-definition video. limit.

CVI, TVI, and AHD realize high-definition transmission on coaxial cables, and the transmission distance increases significantly; they all have higher definition and no bright-color crosstalk than ordinary analog; they are more transparent than SDI transmission. Long distance and strong anti-interference ability; compared with network HD, it has the characteristics of no delay, lossless image and easy operation.

In use, CVI, TVI, and AHD all follow the methods and methods of analog standard definition transmission, which can reduce the complexity of construction deployment, the cost of auxiliary materials and the complexity of maintenance, as well as the technical requirements for construction personnel. ; Suitable for upgrading old systems, and can easily upgrade standard definition to high definition without changing the original system.
