That's why I don't use a video camera, too far for co-ax.
Huh? You can send video over miles of coax, if you terminate it
properly. Hmmm, let's see, 1000' at $0.13/ft = $130, you might be able
to do better on eBay. You can probably send the camera power on the
same cable with a little ingenuity, too.

OK, the price is reasonable for the co-ax. There would be some problems
routing & burying it but it's definitely possible. (since I would have
to bury it I can also bury other wires in the same trench) Video
cameras are reasonably cheap, the problem then comes in data processing
inside my home. I do NOT want to watch live video and am most
interested in events that occur when I'm gone or sleeping, so I guess I
would need some gismo that would record when x pixel changes occur.
Does that mean a dedicated computer with a huge hard drive? My present
Mac only has 6 gB, I assume I would have to buy another dedicated
computer and software for the application - what is the software called?

A program called Gotchya! does just that, triggers a few second of
video or snapshots from a web cam, when ever selected areas (you
select them) change by some percent.
