Our counter surveillance audio jammer protects room conversations where sensitive information may be exchanged by generating a random masking sound which desensitizes any microphone that is near. This jammer is effective against any microphone based eavesdropping device including tape recorders, RF transmitters, hard wired microphones and shotgun microphones.
This is a great unit if you need to guarantee no one is listening.
Each unit protects up to 150 square feet. You can add additional units for larger areas.
