LL-1 contact microphone is a device that has been designed for discreet remote listening indoors. A small contact microphone with the diameter of 7mm has been fixed on a 25-meter long cord. Run the cord through floor strips, in a suspended ceiling or under a carpet. It is important that the microphone is not covered. The device is powered by 9 V battery which allows for about 50 h of continuous listening. Microphone sensitivity allows for sound capturing within about 10 m in a closed room.

Operation of the contact microphone does not require any specialist knowledge. First, arrange the cord in the right place, then connect the microphone and, depending on your needs, connect headphones which are helpful in particular when you carry out interception from behind the wall.
