In the case of a very micro spy high sensitivity, it is even possible toamplify certain waves to capture vibrations and allow the device to better receive sounds through the walls. Some more advanced options even confer the advantage of setting up this sensitivity based on penetrability. This is knowing that the quality of the sound perceived can vary more or less depending on the type of material of the medium that it must cross: concrete, wood, glass, steel, stone, brick ...
