Revolutionizing Surveillance with Laser Microphones
“I think I’ve created the first laser microphone that actually modulates in the radio frequency domain,” Kamkar said. “Once I have a radio signal, I can treat it like a radio, and I can take advantage of all the radio communication tools out there.” In other words, Kamkar converts sound into light, into radio waves, and then and then converted into sound.

Innovative Technology for Surveillance
Kamkar has pioneered a groundbreaking method for converting sound into radio waves through a laser microphone, enabling enhanced surveillance capabilities. By modulating sound into light and then radio signals, Kamkar has revolutionized the way audio data can be captured and analyzed for covert monitoring purposes.
Advancements in Keystroke Detection
Utilizing his laser microphone technology, Kamkar has developed a sophisticated keystroke detection system that can accurately convert typing sounds into clear text. By refining the signal processing and hardware setup, Kamkar has achieved remarkable results in capturing and interpreting keystrokes, expanding the realm of surveillance possibilities.
Transparency in Spy Technology
Unlike traditional spy tools developed for secretive purposes, Kamkar believes in transparency and has openly shared the schematics of his DIY laser microphone spy kit. By making the public aware of surveillance capabilities, Kamkar aims to empower individuals with knowledge to protect against potential privacy breaches and unauthorized monitoring.
