A lot of us learned that way- however the point you're missing is that
you're putting IR sensors tuned out to 300m to guard a bunch of bills
secured in a cardboard box in the middle of Times Square on New Years Eve.

That doesn't change the fact that if you're not doing the basics right
then bells and whistles don't improve your overall security posture as
much as getting the basics right will.

Look at Avishai's study- then tell me that more IDS is the first thing we
need, and do it with a straight face. Passive IR is a cool technology,
but it sure as heck shouldn't be your first or only line of defense.
