This Zmodo 8 channel Security DVR ZMD-DT-SCN8 is the very top of the line digital video recorder. You simply cannot find an analog based video transmission system that can record video in a higher resolution. This DVR records all channels simultaneously at a whopping D1 (approximately 704 x 480 pixels) resolution and at 30 frames per second (real time). You can also set at 15fps speed to get amazing 960H(approximately 960 x 480 pixels) resolution. It provides a recording resolution that further closes the gap between the high definition resolution of expensive state-of-the-art systems and the conventional resolution of analog systems. more »
