For your
protection against listening devices that are not detectable by conventional
methods, the engineers of R.E.I. have developed the ANG-2000 Acoustic Noise
Generator. The ANG-2000 defeats such listening devices as wired microphones
buried in a wall, contact or spike microphones, transmitters located in AC
outlets and laser/microwave reflection from windows. This is accomplished
by producing a security blanket of generated noise completely covering your
private conversations with unfilterable sound. The ANG-2000 is an excellent
addition to high level countermeasures or can stand alone to provide perimeter
protection. Various transducer adapters are included with the ANG-2000 for
coupling walls, ceiling, air ducts, plumbing, windows, etc.
