Guard physical access so a mic/camera (1/8") can't be placed after construction.
Drapes so the lip readers can't see you.
Make sure the drapes block IR. There are instances of even local police forces flooding the front of a house with IR light, and viewing the activities inside with IR viewers -- all of this through closed drapes. -- system@decode.UUCP (System Operator) Cryptography, Security, Privacy BBS +1 410 730 6734 Data/FAX

You mean heat? What did they do, exactly? Erect giant heat lamps in front of the house? No one inside noticed either?

IR does not mean heat. Infra-Red only implies having a wave frequency lower than that of "red" light. There are several bandwidths of IR used for nightscopes that cannot be felt as heat, nor do they increase the surface temperature of the target area to a noticable extent. -ck

What sort of materials DO block IR ? Lycra ? Wool ? Cotton ? And how do we test drapes without buying them first ?
