  • Important!
  • When using supersonic microphone jamming technology it is necessary to remember about limitations resulting from the laws of physics. Effectiveness of jamming depends on the device - the design of some microphones is more susceptive to jamming than of others. For that reason, the maximum effective range of the device can fluctuate around several times. Ultrasounds also bounce off the surface, but they can not penetrate most materials to a great depth, so it is advisable to use the right number of equipment and its location in the room to provide the best security to the privacy of the conversations.
  • The device does not guarantee 100% of the jamming performance, but it outperforms competing solution with its configuration for high performance against microphone in devices such as voice recorders, eavesdropping and seismic microphones, microphones in computers, headsets, cameras and cell phones.
