AHD stands for analog high definition, AHD's birth, is to solve the transmission distance limitations of existing HD solution. As one of new HD analog solution, AHD supports video transmission over traditional RG59 coaxial cable up to 300 meters, and it becomes another alternative for HD analog solution. By the way, it inherits and carries forward advantages of traditional analog solution, video signal are uncompressed, keep all the original video details, to truly achieve high definition uncompressed lossless, no video latency effect. Similar to other HD analog solutions, through using the progressive scan CMOS image sensor, the AHD camera can deliver 1.0 megapixel, 1.3 megapixel, 2 megapixel resolution, added with ICR filter, the camera achieve true day/night video surveillance; and same like the traditional analog system, AHD products support plug-and-play installation, easy to use.
