The ANG-2000 is designed to defeat wired microphones inside walls, contact
microphones, audio transmitters located in AC outlets, and laser/microwave reflections
from windows. Most sound masking systems inject noise into an otherwise benign
environment. In this environment, the occupants must raise their voices above the noise
level to communicate, which invariably, eliminates the benefit of noise masking. REI's
masking system injects noise into the environment perimeter and not directly into the
environment. This approach allows normal conversation while defeating eavesdropping
devices that rely on acoustic leakage.For more information contact us
