The
Laser mike stopper is a unique new counter measure
device designed to work against the laser surveillance
microphone.
How
does laser surveillance work? It's quite sophisticated,
but in a nut shell, 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.
The
Laser mike stopper has been prooved and tested.
(those who best know the capabilities of a technology
are usually the first to realise the importance
of protecting themselves from it). This unique
countermeasure device was designed to be effective,
inexpensive, compact, and portable. It interrupts,
masks, and jams the laser demodulation by transmitting
human voice frequencies to a window to "drown
out" typical conversation. Most laser receivers
have a "notch filter" to isolate and
enhance human voices; this device was engineered
to defeat such filters by centering its frequency
output at the middle of the human voice range
so that if the notch filter is used, it will also
filter out a major portion of the human voice
range, making the results useless.
