Long-Range Laser Listening Device Model AA79106

WARNING: The sale of laser microphones is restricted to Law Enforcement and Government agencies and their authorized suppliers – no exceptions. Laser microphones destined for export require an Export License from the United States Department of Commerce. Contact Argo-A Security for the required license application forms and assistance.

The Long-Range Laser Listening Device is a highly sophisticated surveillance apparatus that utilizes an invisible infrared laser beam to eavesdrop on a target. This is the most effective long-range laser listening device (laser microphone) in the world that allows the operator to conduct an undetectable surveillance operation on any targeted room with at least one window at an impressive distance of over 450 meters.

This laser microphone was specially developed for government and law enforcement organizations to use covertly in situations when entrance in buildings is not suitable or possible for placing a listening device into the targeted area. The Long-Range Laser Listening Device is also highly undetectable as the infrared laser is completely invisible to the naked eye, and both the transmitter and the receiver are built into standard single-lens reflex cameras, allowing for perfect concealment.

The Long-Range Laser Listening Device is an easy-to-assemble and easy-to-use system consisting of three main components: laser transmitter, laser receiver, and amplifier unit with audio recorder. It operates by transmitting an invisible infrared beam to the window of the targeted room. The Long-Range Laser Listening Device detects vibrations on the window glass that are caused by sound waves (speech) inside the room and transmits them back to the receiver. The laser beam, bouncing off the target window, is then converted into electronic signals, filtered, amplified and fed into a dedicated recording unit connected to its own amplifier with speaker and headphones. Real time audio monitoring and recording are possible simultaneously.

The Long-Range Laser Listening Device operates according to Snell's law (the angle of incidence is equal to the angle of reflection), which requires sharp alignment and correct aiming of both the transmitted and received laser beams. To simplify both set up and alignment procedures, as well as ordinary operation of the system, we have provided the Long-Range Laser Listening Device with sturdy tripods and a special search tone device which proves to be extremely valuable and absolutely necessary due to the fact that the emitted laser beam is totally invisible to the naked eye.

We offer four models of this Laser Microphone which vary depending upon the components you desire. The advanced versions are truly professional ones, including everything that is needed for operator security and improved alignment procedures. Please note all models, Basic and Advanced, are complete with nothing extra to purchase.
