If you are looking for a unique countermeasure device against laser surveillance then Laser Surveillance Defeater will be the right product for you!
Laser Surveillance Defeater works as an invisible laser beam is focused on a window. Voices and sounds from within the target area are absorbed by the window and transmitted onto the laser beam. The receiver then extracts, processes, and amplifies the signal.At the end of the process, private conversations inside your office can be secretly listened in on and recorded by a spy.
This model was made to meet the security requirements of certain federal U.S. federal agencies. It is a device that is effective, inexpensive, compact and portable for your convenience. It interrupts, masks, and jams the laser demodulation by transmitting human voice frequencies to a window to make it impossible to hear any typical conversation. Additionally, it was manufactured to defeat filters that isolate and enhance human voices; it is capable of doing this by centering its frequency output at the middle of the human voice range, so that if the such filter is used, it will also filter out a major portion of the human voice range, making the results useless.
