Professional audio surveillance device - listen through walls..

The professional Listening Through Walls device is capable of penetrating walls up to 12 inches in thickness.  The highly sensitive acoustic microphone and fine-tuning noise buffer allow you to hear conversational words on the other side of the wall.  The device also has an output jack allowing users to connect an audio recorder (not supplied) to the device and record the sounds captured if necessary.

This is a professional Listen Through Walls device with a high-sensitivity acoustic microphone amplifier.  When placed against the wall it is capable of penetrating thickness up to 12 inches, thus allowing you to hear the audio/conversations on the other side of the wall.  The wall must be solid, no gaps, any cavity will stop the product working efficiently.

The Listen Through Walls Pro is made of high-quality brushed aluminum and fitted with a fine-tuning filter to provide clearer audio listening quality, plus an audio output socket which allows a digital voice recorder (not supplied) to be connected to capture audio evidence.

It's very easy to use. The ceramic contact microphone is gently pressed and held against any solid wall, retrieving vibrations sent back through the wall and converted into audible sound through the earphones (supplied).  It's powered by a PP3 battery and provides up to 24 hours of continuous use.

Frequently asked questions about the listen through walls system:

CAN THE LISTEN THROUGH WALL PICK UP AUDIO THROUGH 12" OF SOLID BRICK?

Yes. The thicker the wall, the better.  The wall must be completely solid between you and the wall next door and without a cavity gap between the walls; otherwise, the vibration hits the cavity gap and cannot push through the other side of the brick wall.

HOW LONG MAY I LISTEN FOR?

A single lithium PP3 battery will power the device for 24 hours of use.

HOW DO I USE THE LISTEN THROUGH WALL DEVICE?

Switch ON the device and connect the supplied earphones. You may connect any high-quality earphones.  Next, hold the ceramic microphone against the solid wall to hear what is being said through the wall.  Use the fine-tuning filter dial to refine the audio to your liking.
