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