Laser Room Monitoring

Laser Room Monitoring Device Laser Room Monitoring Device

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 audio recorder. The complete system is supplied in large water proof transportable camera case, including the amplifier, the filters, search tone detector, wireless headphone 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. Both, the transmitter and the receiver are built into a standard single lens reflex cameras, allowing for perfect concealments. The complete set comes in a foam padded camera case with built in recorder, two camera tripods and one micrometer platform with adjustable Y/X axis and search tone-detector.
