So how does it work?
This surveillance device works by amplifying the vibrations of audio. When children or subjects are in a room their voices are simply a waveband, and depending on how loud they are talking, the waveband travels short and long distances which are picked up and amplified by this style device.
The sensor on this surveillance device senses the vibrations hitting the walls, ceiling and floor and amplifies them so that you can hear and listen to what is happening. If the waveband is low, meaning people speaking in a lower note, then you can use the dial located at the back of this Audio Listening Device to adjust the volume and increase the sensors amplification. It really makes "surveillance" more productive. Know if subjects are watching TV or up to suspicious behavior.
So the device can tell you some amazing things behind you and i think it can help you a lot sometimes.

A:How far you can listen through this device?
Q:This audio spy bug working range depends on the thickness of the wall, best when used on barriers that are 6 to 10 inches by thickness. It might also work well with distances of 10+ meters (appr. 30 feet), depending on the volume of sounds on the other side of the wall.
