It's quite sophisticated, but in a nutshell, an invisible laser beam is focused on a window. Voices and sound from within the target area are absorbed by the window and transmitted onto the laser beam (called "modulation"). The receiver (at the other end of the beam) then demodulates, processes, and amplifies the signal. The result -- your private conversations inside your office or home can be secretly listened in on and recorded by a spy a mile away! Since these systems are expensive and sales are restricted in the U.S., they are used primarily by government agencies. Ever seen the hit movie Eagle Eye (2008)? This is a perfect example of when a laser surveillance defeater could be used to block demodulation: It's too bad the coffee gave it away! The new Laser Surveillance Defeater was developed to meet the security requireme
