This Listen through the Wall Device could provide essential evidence for any private detective and private investigator as it can pick up even minute sounds, via a special amplifier, by way of walls, windows or partitions. Attached to the amplifier is actually a very sensitive ceramic microphone which is developed to pick up vibrations that are converted into a voltage which could be then be created into audible sound. The amplifier has an adjustment to enable the sounds to be heard clearly and in the needed volume.
Private detectives and private investigators can simply hold the device to the surface in question, up to 300mm thick, after which listen in by way of stereo headphones. All of the evidence can be recorded by connecting a recording device, like an MP3 player, into an audio output socket. A 9 volt battery powers the listen through the wall device and will give private detectives and private investigators up to 24 hours of use. This really is surely a really valuable piece of kit for every private detective and private investigator.
