This Listen via the Wall Device could present crucial evidence for any private detective and private investigator as it can choose up even minute sounds, by way of a unique amplifier, through walls, windows or partitions. Attached to the amplifier is actually a very sensitive ceramic microphone which is developed to pick up vibrations which are converted into a voltage which can be then be produced into audible sound. The amplifier has an adjustment to allow the sounds to be heard clearly and at the needed volume.
Private detectives and private investigators can simply hold the device to the surface in question, up to 300mm thick, and then listen in via stereo headphones. All of the evidence can be recorded by connecting a recording device, for example 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 really is surely a very valuable piece of kit for every single private detective and private investigator.
