The “LE5000” is a long range, State of the Art, highly directional microphone specially developed for Governments and their Law Enforcement organizations, to be used covertly in situations when entrance is not suitable for placing a listening device into the targeted room. It allows the operator to carry out undetectable, long range surveillance from the outside of the building.
 
The “LE5000” consists of three parts: 
ï          LE5000 Transmitter
ï          LE5000 Receiver
ï          Amplifier Unit with Audio-Recorder
 
This system is operated by transmitting an invisible IR (Infra-red) beam to the window of the target room. It picks up the vibration of the window pain, according to the sound waves emanating from speech, bounces it back to the Laser Optical Receiver where the modulated beam is synonymously converted into electronic signals, which are then interpreted back into audible voice, amplified and fed into a professional UHER recorder. The complete system is supplied in large water proof transportable camera case, including the amplifier, the filters and the recorder. It transmits and records sound wave vibrations, reflected of smooth surface of the glass ( single or double thermo pane ). Rippled or grained glass will not provide a suitable reflecting surface and in most cases it will not work. However, acoustic interferences caused by interior or exterior sound wave reflections may be filtered and modulated trough the Lasers Optical Receiver. The transmission may be also fine tuned by modulating the search tone or by changing the placement of the receiver itself.
