Noise generator The Stealth DNG2300DTN
The Stealth DNG-2300 is designed to prevent listening though devices that cannot be detected by conventional countermeasures and installed around the perimeter of a room – wired wall microphones, contact microphones, AC outlet transmitters and window systems based on the reflection of laser/infrared/microwave beams. It is an excellent addition to high level countermeasures.
It uses a combination of transducers and speakers placed strategically throughout a target area to create a blanket of masking noise that covers private conversations from eavesdropping.It is well-known that sound distributes though walls, doors, windows and other constructions. In some materials sound travels even better than through air. For example, water is a good conductor and a heating system can pass a conversation out of a room. Eavesdroppers take advantage of this with the use of contact microphones. These microphones pick up the vibrations from the air ducts, plumbing, structures, walls, windows, doors, floors, ceilings and more. The microphones may not be in the same room as the conversation, but may be several floors or rooms away attached to a pipe or other fixture.The Stealth DNG-2300 can render these devices useless. It produces non-filterable acoustic noise which is transferred to constructions by transducers and speakers. REI’s TRN-2000 is the recommended transducer for use with the Stealth DNG-2300. It has optimal power parameters and can be set on different types of surfaces. The TRN-2000 injects most of its power into surfaces while only a tiny part of the noise gets inside a room. This does not force people to speak louder. The TRN-2000 transducer can be supplied with adapters for mounting on walls, ceilings, windows, etc.The speaker OMS-2000 can also be used with the Stealth DNG-2300. It does not inject the noise into the surfaces but radiates it into surrounding space. The OMS-2000 is usually used in air ducts, ceiling tiles, etc.It protects from
