This Listen via the Wall Device could provide essential evidence for any private detective and private investigator as it can pick up even minute sounds, by way of a special amplifier, through walls, windows or partitions. Attached to the amplifier is a extremely sensitive ceramic microphone which is created to choose up vibrations which are converted into a voltage which may be then be made 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 merely hold the device to the surface in question, as much as 300mm thick, and then listen in by way of stereo headphones. All 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 up to 24 hours of use. This really is surely a very helpful piece of kit for each and every private detective and private investigator.
