Listen Through Walls Professional Device
Listen Through Walls Professional is a professional-grade surveillance device comprising a highly sensitive contact microphone and a powerful amplifier unit, allowing you to pick up and amplify even the faintest sounds (as low as -80dB) through doors, heating pipes, walls, ceilings or floors, made of concrete, wood, drywall, brick, steel, etc. It is ideally suitable for professional surveillance tasks where sound clarity and high amplification are required, allowing you to hear sounds in the next room as if you were there.
Mode of operation
Sounds produced in a room adjacent to yours are sound-waves that reverberate against the wall, being deflected, muffled and dispersed by it. When you place the contact microphone device against the wall, it picks up those residual vibrations and passes them to the amplifier unit, which parses, amplifies and converts them back to original sounds, so that you may hear the sounds in the adjacent room as if you were there.
• Highly sensitive, detachable contact microphone
• Discreet, portable amplifier unit in a rugged, highly durable metal casing
