The Laser Defeater X-11
The "New" X-11 Laser Bug Jammer
This unit can jam and block laser frequencies with static "white
noise" that will keep your conversations safe.
EASY TO USE AND
The Laser Surveillance Defeater is a unique new countermeasure
device against laser surveillance.
How does laser surveillance work? 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
The new Laser Surveillance Defeater was developed to meet the
security requirements of certain U.S. federal agencies (those who
best know the capabilities of a technology are usually the first to
realize 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.
The Laser Surveillance Defeater is ideal for government offices,
corporate facilities, high-rise buildings, even homes-- any location
that has a window which can be seen from a spy's location is at
potential risk of laser surveillance. This device is completely
portable; it installs and un-installs on windows instantly with its
integral suction component. Powered by one 9-volt alkaline battery
(included), which provides approximately 500 hours of operation.
Equipped with on/off switch and bright blue LED power indicator.
Deploy one unit per window.
