Is it the norm for makers of DVRs to advertise the feature
of being able to add on storage arrays, and then, without
stating such up front, make the compatibility a proprietary
interface, so you can only use thier devices?

Most makers offer their own ready made add on storage, which has been
configured, and tested throughly to work with their equipment. Most of
the expansion I've seen has been SCSI (and now some USB and SATA is
starting to appear), which you could probably build a custom add on
for. However, the manufacturer would advice against it, because they
cannot test every configuration possible, and they won't warrenty any
damage that could be caused by some off the wall setup. It's most
likely possible (there are only so many interfaces that exist for hard
drives), the companies 1: don't want to risk the customer screwing
something up by 2: offering a product that may be a bit more than you
could buy yourself at newegg, but it has been engineered and tested to
work reliably with the product.

There are many ways to use storage for video. You are not mentioning what
type of DVR you are using, but it is unlikely that a simple DVR manufacturer
would R&D his own complete storage solution. Have you looked at places like
http://www.infortrend.com/main/index.asp or http://www.nexsan.com/ or even
http://www.emc.com/ for some direct attached solutions? You may find the
clone of what you think is proprietary gear. Unfortunately many of these
solutions are not available to anyone without special training or other
arrangements with the manufacturer. If you are talking about an iSCSI
solution, instead of direct attached storage, there is a problem there with
many units due to the number of LUNs available. Typically every video inputs
from an IP address (like an IP camera or video encoder) gets its own LUN.
Many manufacturers create iSCSI arrays geared to work with a single server
or smaller group of servers. Therefore you might find an iSCSI device with
enough total storage capacity to meet your retention time needs, but lacking
the LUN capacity to handle the number of inputs you plan to deploy. However,
if you keep looking I think you might find the actual storage manufacturer.
Getting a unit like that configured and working and keeping it working
without factory tech support might make you wish you hadn't found it.
