This Listen by way of the Wall Device could offer vital evidence for any private detective and private investigator as it can choose up even minute sounds, via a special amplifier, via walls, windows or partitions. Attached to the amplifier is actually a very sensitive ceramic microphone which is created to pick up vibrations that are converted into a voltage which may be then be created into audible sound. The amplifier has an adjustment to enable the sounds to be heard clearly and at the necessary volume.

Private detectives and private investigators can simply hold the device to the surface in question, up to 300mm thick, after which listen in via stereo headphones. All the evidence may be recorded by connecting a recording device, for example 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 as much as 24 hours of use. This really is surely a really valuable piece of kit for every private detective and private investigator.
