Laser Microphone Model AA79107

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 AA79107 Laser Microphone is a professional piece of equipment allowing the operator to carry out undetected surveillance from outside a building. We can state emphatically that we offer the best laser listening devices in the world. These professional long distance laser audio listening instruments are the most reliable tools that law enforcement and government agencies can deploy in a matter of minutes for achieving the tactical advantage in a critical situation.

Thanks to its unparalleled features, the AA79107 Laser Microphone is able to pick up room audio from a distance without entering the target room: by demodulating the transmitter IR laser beam bouncing from the target window, this equipment can receive and subsequently convert into electronic signals the slight window pane vibrations caused by acoustic waves in the room (voice speech).

The laser beam bouncing off the target window is then converted into electronic signals, then filtered, amplified and fed into a dedicated recording unit connected to its own amplifier with speaker/headphones; real time audio monitoring and recording are possible at the very same time.

The whole system operates according to Snell’s law, 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 AA79107 with sturdy tripods and a special searchtone device which proves to be outstandingly valuable and absolutely necessary owing to the fact that emitted the laser beam is totally invisible to the naked eye.

Advanced versions feature additional accessories specifically developed to ensure system security and ease of use.

The AA79107 model Laser Microphone is the only newly-designed laser microphone in the world to offer both active and passive operation. When used in active mode, simplified alignment and outstanding listening quality for the device will be possible without entering the target premises regardless if there are target windows available.

When no target windows are available and the use of passive listening mode is not possible, it is sufficient for the SWAT team to plant a very tiny device on the outer walls of the target room or building and remote room audio monitoring from up to 800 meters away (maximum operating range at night under ideal conditions) is just a few minutes away.  

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.
