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.
