One could argue that all electromagnetic radiation is in the public domain and receivable. However it is illegal to have equipment capable of receiving cell phone conversations because the rights of the telephone company and the rights of the conversants could be violated. IR equipment is capable of seeing far more from outside a house than just the wall temperature. This kind of surveillance is clearly invasive, in my opinion.
Certainly gives a new twist to TEMPEST. I suppose now if you wanted to tempest your home, you'd additionally have to install randomly "blinking" heat generators. Hmmm, something like a big grid of resistors where they get turned on and off at random. You might want the resistors to spell out "Mind your own business, pigs!" when viewed with a thermal device, but of course this kind of thing will only attract their attention. You could also use peltier coolers, but they generate heat on the other side. Another option would be to get big huge water circulators and call it art - there are a few restaurants here in NYC where they have water running over glass panes. It's a nice calming waterfall effect. :) -- ----------------------Kaos-Keraunos-Kybernetos--------------------------- + ^ + :Surveillance cameras|Passwords are like underwear.
