This Listen by means of the Wall Device could supply vital evidence for any private detective and private investigator as it can choose up even minute sounds, through a unique amplifier, by means of walls, windows or partitions. Attached to the amplifier is a very sensitive ceramic microphone which is designed to choose 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 merely hold the device to the surface in question, up to 300mm thick, after which listen in through stereo headphones. All the evidence could be recorded by connecting a recording device, including 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 up to 24 hours of use. This is surely a very helpful piece of kit for every private detective and private investigator.
