What's the difference between CVI camera and AHD camera?

The difference between ahd camera and cvi camera is as follows:

1. As far as the output image effects of the two are concerned, there is basically no difference between camera images with the same resolution;

2. ahd is a kind of analog camera. ahd simulates a high-definition camera. In the final analysis, it is still an analog camera, similar to tvi, cvi and sdi. Ahd is as simple and convenient as traditional equipment. Ordinary 75-3 coaxial cable can be used for lossless transmission of high-definition video up to 500 meters, which breaks through the transmission limit of existing high-definition video transmission technology, and can realize low cost, long distance, no delay, high efficiency, anti-interference and easy to realize high-definition video transmission of millions of pixels.

3. hdcvi (high

definition

composite material

videotape

Interface), hdcvi is a high-definition composite video interface, which is a high-definition video transmission standard based on coaxial cable, and adopts analog modulation technology to transmit progressive high-definition video. Hdcvi technology adopts self-adaptive technology with independent intellectual property rights, which ensures the transmission of at least 500m high-quality high-definition video on coaxial cables of 75-3 and above specifications, and breaks through the transmission restrictions of existing transmission technologies on high-definition video. In addition, hdcvi technology also has a number of independent intellectual property technologies, including synchronous audio signal transmission technology and real-time two-way data communication technology.
