Laser Surveillance Anti-Ease Dropping Device

The Laser Surveillance Defeater is a new and unique device to counteract laser surveillance.

Laser surveillance is kind of a complicated subject, but the basic principal is all about vibrations. First, an invisible laser is beamed onto a window or a wall. Inside the room, voices and other sound waves are absorbed by the window, causing slight vibrations. The laser picks up the modulated vibrations, and beams the information back to the reciever unit. The receiver then demodulates the data, processes it, and amplifies the signal, essentially giving the user a long-range ear pressed up against a wall. These systems are usually very expensive and sales are mostly restricted to government agencies.

The Laser Surveillance Defeater was designed to meet certain security requirements of different US federal agencies. The clever device is designed to be compact and inexpensive. It works by transmitting frequencies matching the human voice to a window or wall to create enough noise to mask normal conversation. Most laser receivers have settings to isolate and enhance human voices, and this device was specifically designed to overcome those filters by using frequencies at the middle of the voice range, making the resuls for the opposite party 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 spys 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, which provides approximately 500 hours of operation. Equipped with on/off switch and bright blue LED power indicator. Deploy one unit per window.
