Protect yourself from modern laser surveillance technology and prevent other people from listening in on your conversations with the Laser Surveillance Defeater. Developed to meet the security requirements of federal agencies, this countermeasure device is an effective, inexpensive, compact and portable way to interrupt, mask and jam laser demodulation. It works by transmitting human voice frequencies to a window to drown out conversation. It's even designed to defeat notch filters on laser receivers, which isolate and amplify human voices.
We recommend these home/automobile laser defeater devices for government offices, corporate facilities, homeowners, business owners and more. This portable laser defeater device is powered by a single 9-volte alkaline battery (included), that provides up to 500 hours of operation. It has an on/off switch and a bright blue LED power indicator. For best results, deploy one unit per window.
