DVRs

Picture quality can refer to many things. The most common refers to the resolution displayed. Is the image displayed at 1 CIF, 2 CIF, 4 CIF, or D1? The best DVRs combine high frame rates per channel with high resolution. A top quality DVR such as an AD Intellex Ultra may be able to process 30 images per second for 16 cameras (480 IPS total) at 2 CIF. Compare these stats to the cheaper DVRs and you'll see the difference.

Common Intermediate Format. A standard size for images produced by low-resolution digital cameras and video cameras. CIF images are 352 pixels wide and 288 pixels tall (352 x 288). CIF is larger than QCIF and QVGA, but smaller than VGA.

The Eco 4 by DDM will probably be adequate fro your application. Nothing fancy, but it works reliably. I have installed a couple of them.
