A long-range audio pickup device using an invisible laser beam (1550 nm wavelength) projected onto surfaces such as glass, metal, paper or plastic to capture acoustic vibrations without direct contact.
Description & Features
A long-range audio pickup device using an invisible laser beam (1550 nm wavelength) projected onto surfaces such as glass, metal, paper or plastic to capture acoustic vibrations without direct contact. It enables recording or monitoring of conversations inside enclosed spaces such as meeting rooms or vehicles from a distance of up to several hundred meters. Surveillance is fully covert, leaves no trace, and is eye-safe thanks to the use of an appropriate laser wavelength.
