The difference between an AHD camera and a CVI camera
The difference between an AHD camera and a CVI camera is as follows:
In terms of the output image effect of the two, there is basically no difference between the camera images of the same resolution;
AHD is a kind of analog camera, AHD analog high-definition camera, in the final analysis is analog camera, similar to TVI, CVI, SDI; AHD is as simple and convenient to operate as traditional equipment. It can transmit up to 500 meters of high-definition lossless transmission with ordinary 75-3 coaxial cable, breaking the transmission limit of HD video transmission technology, enabling low cost, long distance and no Time-delayed, high-efficiency, anti-jamming and easy-to-implement megapixel HD video transmission.
HDCVI (High Definition Composite Video Interface), HDCVI is a high-definition composite video interface, is a high-definition video transmission specification based on coaxial cable, using analog modulation technology to transmit progressive HD video. HDCVI technology adopts the self-adaptive technology of independent intellectual property rights to ensure that at least 500 meters of high-quality HD video is transmitted on coaxial cables of 75-3 and above, breaking the transmission limit of the existing transmission technology of high-definition video. In addition, HDCVI technology also has a number of proprietary intellectual property technologies, including synchronous audio signal transmission technology and real-time two-way data communication technology.
