LASER-AUDIO SURVEILLANCE

Laser-audio surveillance

The Long-Range Laser Audio Surveillance Device (Laser Microphone) is a highly sophisticated system designed for covert audio intelligence gathering over long distances. It uses an invisible infrared laser beam to detect vibrations on glass surfaces (such as windows) caused by speech inside a target room.

This technology enables operators to monitor conversations without physical access to the building or the need to install any device inside the target area. With an effective range of over 500–1000 meters, it provides a significant tactical advantage in surveillance operations.

The system works by directing an infrared beam at a window. The reflected beam carries information about sound-induced vibrations, which are captured by a receiver, converted into electronic signals, filtered, amplified, and processed into audible sound. Real-time monitoring and simultaneous recording are fully supported.

Thanks to the use of invisible infrared technology, the system remains highly covert and virtually undetectable. Both the transmitter and receiver are integrated into housings resembling professional photographic equipment, ensuring effective concealment during operations.

The system is modular and easy to deploy, consisting of three main components: transmitter (TX), receiver (RX), and a control unit with amplifier, equalizer, and recording device.

Available in Basic and Advanced versions, the advanced configuration includes additional features such as digital noise reduction, IR passive/active mode switching, and extended operational accessories.
