Wall microphone
This unit has a built-in amplifier earphones and wall mic. It is a very sensitive device. This wall microphone device was designed for situations where access is limited or impossible. This is a high gain oscillating receiver which uses a special contact device. The contact can be placed against doors made of glass, concrete, or metal, up to 30cm thick. We have used it successfully through besabrick walls. The oscillator can then be connected to a recorder to record all conversations. The user can also listen to the conversations live, while recording. It measures approx. 100mm X 50mm and is powered by a standard 9 volt battery.
