Complete Counter-Surveillance in One Portable Device

The Stealth SM2020 is a professional-grade portable speech protection system that defends against listening and recording devices. The SM2020 creates sound barrier interference which masks your speech and any sound to be extremely difficult or impossible to extract the original content from the noise. This all-in-one counter-surveillance tool will not only block listening devices from listening in on your conversations, but its built-in RF (radio frequency) detector will find any bugs in your immediate surroundings.

When used properly, this Portable Speech Protection System will protect you from:

  • Voice Recorders (tape and digital)
  • Microphones (including wireless microphones)
  • Stethoscopes
  • Laser Listening Devices
  • GSM/Bluetooth/WiFi Transmitters, etc.
