DVRs

[Matt Ion]

2 to 4 cameras and one dvr.

Starting to wonder again of pc based dvr isn't the way to go.

Check out something like this:

You could pick up a very basic PC for under $300 that's more than
sufficient for two-tofour cameras (here's an example of what I can get
here in Vancouver: http://a-power.com/sys/ap04-soho.asp), plug a VJUSB4
into it (find a local dealer from VI's website), and you're off to the
races for well under a grand!

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.

What does CIF mean?

 

[FDR]

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.

Thanks.

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.

My $1k was the allocation for the DVR portion. I already own some nice
cameras.
