For Larger jobs use the WNG Kit Pro Listening devices, bugs, thin walls or the carrying of a voice don’t stand a chance against the WNG Kit Pro White noise generator sound masking system.
When the white noise generator is paired with the transducers and speakers, it produces a low level audible interference by creating vibrations onto the surface of the walls in the protected space. If any form of eavesdropping devices are used it will block the voices and instead it will pick up and relay back the vibrational white noise created by the counter surveillance device. You’ll want to have a good spread of transducers and speakers amongst the wallspace, the number will depend on the size and construction of the room. (all devices also sold separately) installation required.
