The Infa-Red cameras detect heat and thats it really. - Unless you have Several 400w Lights and Generators running giving of lots of heat, you really should be ok.

However if your still a bit paranoid, There is one thing Infa-Red cant see through.. Lead!
My friends has a cupboard that is caked in Lead roof tiles. Something like this would be ideal.

As far as the law go's over here in the UK, the police can do whatever the fuck they want with there thermal imaging shit. They don't need a warrant, just air permission.

The police over here can pull you for anything tho, i mean anything.
They can pull you for smoking in enclosed public spaces, spitting or even dropping a ciggy butt.

I have been nicked before, the police were rather nice too me, but then during an interview things got ugly, I swore at them an awful lot! They then gave me a Section 8 (Correct me if its not a section 8) Public Offense Order... For VERBAL ASSAULT!

Yeah thats right £80 that i dont have, just so i can swear.
Well fucking worth it, Its not taught me a fucking thing.


Peace
