25 Years Experience With Male & Female Detective Agency AvailableThis Listen via the Wall Device could offer crucial evidence for any private detective and private investigator as it can pick up even minute sounds, via a unique amplifier, by way of walls, windows or partitions. Attached to the amplifier can be a extremely sensitive ceramic microphone which is designed to choose up vibrations that are converted into a voltage which can be then be produced into audible sound. The amplifier has an adjustment to enable the sounds to be heard clearly and in the necessary volume.
Private detectives and private investigators can basically hold the device to the surface in question, up to 300mm thick, and then listen in via stereo headphones. All 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 via the wall device and will give private detectives and private investigators as much as 24 hours of use. This is surely a very valuable piece of kit for every private detective and private investigator.
