AHD DVRs

AHD (analog HD) security recorders are mostly hybrid and will support 960H analog as well, for recording analog cameras up to 1000 TV-Lines. AHD is a lower-cost HD option, and it is ideal for residential or small business use. Picture quality is much better than non-HD analog, and is almost as good as HD-CVI or HD-TVI. AHD is not as good in quality as IP or HD-SDI.
