A professional tool of the American REI (Research Electronics International) brand enables creating a signal which allows to protect the room efficiently against listening-in from outside. Prevents the various types of surveillance: by use of wired microphones hidden in walls, seismic wiretaps, transmitters installed in electric system, parabolic microphones, laser and microwave wiretaps.
White noise generator - ANG-2200 enables generating truly random noise, so there is no possibility of recovering its characteristics basing on statistical tools, which would enable filtering the signal of speech from the recorded disrupted data. Additionally, two independently regulated channels (changing of intensity and frequency components of noise) allow using one generator in a place where there are different disrupting signal characteristics needed. For example – one generator may be used for protecting walls and windows.
The White noise generator - ANG-2200 should be adjusted to use in a given room with taking its characteristics into account – its surface, number of windows and doors and amount of adjacent empty spaces. Disruption with random signal is implemented in the structure of building by use of special TRN-2000 converters designed for this purpose. They are installed once a given distance, inside the walls, floors and ceiling, on windows (thanks to additional WMT-2000 grips) and in doors. OMS-2000 multi-directional masking speakers are used for protection of adjacent empty spaces. The analysis of the spectrum of leak from the protected room and optimization of system's operation is performed by a specialist White noise generator - ANG-2200 software.
