Description

Wall Contact Microphone
Contact Mics Used for Letter Bomb Detection & In Wall Water Leakages


  • Works on wooden walls, doors, windows, steel plates, etc.
  • Volume Dial to amplify sounds
  • An investigative tool for law enforcement or licensed investigators

As simple and powerful as possible from a handheld listening device, this wall contact microphone also known as a letter bomb detector can let you hear minute sounds from within a wall by simply placing the spy device against the surface, turning up the mic sensitivity and with the included earphones, listen directly to what sounds are being generated.

This spy audio gadget works by amplifying the vibrations of audio. For instance, if there were a leakage within the wall of your home, and this spy device were placed against it, the wavebands that are generated by the leak will be detected and amplified by the contact microphone.

The sensor on the wall contact microphone senses the vibrations hitting the walls, ceiling and floor and amplifies them so that you can listen to what's being generated. If the waveband is low, meaning sound is fate, then you can use the dial located at the back of this cool audio spy gadget to adjust the volume and increase the sensors amplification.
