This Listen through the Wall Device could present important 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 really a highly sensitive ceramic microphone which is created to pick up vibrations that are converted into a voltage which could be then be made into audible sound. The amplifier has an adjustment to allow the sounds to be heard clearly and at the required volume.

Private detectives and private investigators can merely hold the device to the surface in question, up to 300mm thick, and then listen in via stereo headphones. All of the evidence may be recorded by connecting a recording device, like an MP3 player, into an audio output socket. A 9 volt battery powers the listen by means of the wall device and will give private detectives and private investigators as much as 24 hours of use. This is surely a really beneficial piece of kit for every single private detective and private investigator.
