Laser microphone for discreet eavesdropping - Spectra M

Laser microphone Spectra M is a professional piece of equipment able to eavesdrop on a conversation from up to 400m without entering the monitored room. An invisible laser beam plays the role of a sound-carrying medium.

The Spectra Laser M is a professional device and one of the best long-range laser microphones in the world. Unlike many educational and amateur projects on the market, this device was specially designed for law enforcement personnel, special forces and professionals who value reliability. One of its main advantages is the fact that the laser microphone can be installed and adjusted in a few minutes, whenever the speed of acquiring information for gaining a tactical advantage in a critical situation is of concern.

The precision of the laser microphone is so high that it is able to reconstruct a conversation on the basis of window glass vibration caused by the sound waves. The laser beam is partially reflected by the window glass and modulated by its microvibrations which makes it a valuable source of information. This cutting-edge device simply pushes you close to the limits of physical laws. Moreover, the Spectra M is very reliable and efficient. Well-thought-out technological solutions and compact modular design makes it very portable and easy-to-install in any place. It is also fully adjustable which greatly facilitates aiming at the right window in a most efficient way.

Main advantages of the Laser microphone for discreet eavesdropping - Spectra M:

• ability to eavesdrop on a conversation through the window glass without entering the monitored room
• 400m range
• uses an invisible infrared laser beam
• separate transmitter and receiver module make it possible to eavesdrop even when the perpendicular orientation is not achievable
• portable and very compact design
• double signal output (original and converted signal)
• multi-band equalizer with digital sound processing
• multi-band tonal signal in a 50Hz – 20kHz range
• innovatory beam modulation technology makes it undetectable for other devices
• integrated digital recorder automatically stores all intercepted information
• optical aiming system of the laser microphone facilitates the process of aiming laser at the target
• micrometrical regulation in three dimensions for the ultimate precision
• encrypted radio link makes it impossible to intercept the device's internal communications
• double power feeding mode (battery power or DC power adapter)
