Glass sound interference system QYBM-GR III

Glass sound interference system QYBM-GR III

The vibration source is a speech related interference signal, and the original sound information cannot be restored from it; Adopting battery independent power supply mode; The remote control can be used to adjust the switch and interference intensity.
The principle of laser eavesdropping is that the eavesdropper shoots a beam of laser light onto the door and window glass of the room being eavesdropped on, detecting small changes in the reflected laser light, so as to monitor the voice in the room. When someone is talking in the room, the glass vibrates slightly due to changes in indoor sound, and the laser reflected back from the glass contains indoor sound wave vibration information. At a certain location outdoors, a specialized receiver can be used to demodulate the sound signal.
To prevent possible laser infrared eavesdropping, attach the anti laser eavesdropping voice related interference device to the window glass or place it near the window, apply interference vibration on the glass, and add noise to the reflected beam of the possible laser eavesdropping device, so that the laser eavesdropping device cannot receive the modulated signal of the voice.
The anti laser eavesdropping interference machine adopts an independent installation method, powered by batteries, and easy to disassemble and assemble. You can use suction cups or fix the product on key and critical parts of the door and window glass by pasting.
