NG-2200 is an acoustic jammer, intended for protection against eavesdropping devices like wired microphones inside walls, contact microphones, audio transmitters located in AC outlets and laser/microwave reflections from windows.
ANG-2200 works together with both TRN-2000 transducers and OMS-2000 omnidirectional speakers.
ANG-2200 uses white noise signal with very low predictability characteristics, making it virtually impossible to recover original discussion within protected area by digital processing of the jammed signal.
