This technology is being used by the secret services! It is possible to receive the signal using a standard FM radio receiver. Board Dimensions: 20mm X 10mm. The board is so tiny that it could be placed on the top of a finger, it's size is less than a human nail.A highly sensible piezo-sensor is a microphone. When any sound appears (including talking voices), sound waves make window glass vibrating. The piezo-sensor catches these vibrations of the window glass, intensifies them and sends to the transmitter. Thus, the Wall Bug catches all sounds both inside and outside of the window. Of continuous running using only 2 batteries with a diameter of 20mm!!
Unlike other devices of it's type, we provide our transmitter with built in battery holder. All you need to start working is to insert 2 batteries in the battery holder. The device antenna is not simple.It is designed specially for frequency of transmitter broadcasting, its length is about 80cm and it is made of isolated wire, as thin as human hair (0.4mm only). That's why the antenna is practically invisible for everybody. 2 high quality lithium batteries CR2032 are absolutely free!! High sensitive piezo microphone built in transmitter. Battery holder for 2 batteries built in transmitter.
Special case for storing the transmitter. A strip of the double sided tape to fix the transmitter on glass. And you get 2 high quality lithium batteries absolutely free!! Today you have such opportunity!! The transmitter is designed and made in Israel, based on the secret services technologies.Each transmitter is tested and tuned in specialized laboratory by high skilled engineers. Small size and weight of the transmitter allow to install it using double sided tape on any part of glass. In spite of very small size the microtransmitter is powerful enough and catches even weak sounds at the distance of up to 10 meters from the glass and transmits the output signal away. It is necessary to remember that after finishing the work with transmitter the batteries should be removed from the battery holder and kept separately!! The possible areas of Micro Wall Bug usage.
Ideal for surveillance, communications, anti-theft. You can tune it easily by yourself.
