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 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
– Electronic stethoscopes (contact microphones)
– Microphones built in the walls or other constructions
– Laser and microwave surveillance systems using reflections from the windows
– Other vibro-accousic ways of information’s leakage
– Frequency response: 250-6500 Hz
– Power: 110 V AC, 220V AC
– Electronic stethoscopes (contact microphones)
– Microphones built in the walls or other constructions
– Laser and microwave surveillance systems using reflections from the windows

DTN-360 degrees Ultrasonic Smartphone / Voice recorder Jammer GTG-2040
Ultrasonic voice recorder jammer aimed to prevent you from unsanctioned recording on digital voice recorders, Dictaphones, smartphones and other voice recording devices.
This jammer can be used where negotiations and talks take place. The unique feature of this unit is that it has 48 ultrasound emitters, which are placed in circle for jamming any voice recording devices around the jammer.
Due to its formation we could achieve 10 meter suppression around the jammer.
This range however depends on voice recording device and its quality. Jammer works as a directional ultrasonic suppressor, inflicting jamming on voice recording device’s microphone membrane, which makes impossible to record or comprehend your conversation within jammer range. Additional acoustic jamming creates noise background which is human-like speech, which can be adjusted. In case when your conversation was recorded, the record will contain lots of voices making it harder to distinguish a single one.

DTN-Ultrasonic voice recorder and Smartphone jammer GTG-2070 GSM
The “GTG-2070 GSM” dictaphone suppressor is a suppressor of all types of dictaphones intended for use in office and meeting rooms. The device is mounted under the table, and emits ultrasonic directional waves in a radius of 255 °, preventing possible audio recording. This device is equipped with 24 ultrasonic emitters, the impact of which on recording devices will not allow the recording of a conversation. The power of the suppressor is carried out from 220V or from the battery (optional). For inconspicuous on and off, a remote control is provided.
The “GTG-2070 GSM” suppressor is intended for indoor use and is installed under the table at which negotiations are planned. Thanks to the directional ultrasound emitters, audio recording is possible only from your side behind the suppressor. The interlocutorswill not be able to record the conversation, since the emitters of the suppressor will be directed in their direction.
Features
Only you can record a conversation.DTN-Ultrasonic voice recorder and Smartphone jammer GTG-2070 GSM is a device use to suppress all recording devices within a radius of 255 °. Only you can record.
DTN-Ultrasonic voice recorder and Smartphone jammer GTG-2070 GSM emitters affect the microphone use in secret recordings, thereby making it difficult record and damage any recordings.
Blocking data transfer. The built-in communication suppressor blocks communication in the GSM, Wi-Fi, 3G, 4G, LTE, GPS bands, thus making the transmission of information impossible.
The suppressor is fixed under the table, hidden from the views of visitors, and it works r silently.
The backup battery can last for about 2hour in the absence power.
Protection from laser microphones (optional,). At your request, this device can be equipped with special vibro-acoustic emitters, which prevent remote reading of information from the window glass of the meeting room and provide reliable protection against laser microphones.

Druid-D06-DTN
The DRUID is an unique system for providing protection for a human’s speech. Not all listening devices can be detected by existing methods. Remotely controlled radio microphones, wired microphones, passive resonators, miniature voice recorders – practically all these devices cannot be detected by conventional methods. Even a modern cellular phone may contain a digital voice recorder; this means that any phone lying on the desktop could be used by an adversary to record a conversation.
The generated audio interference cannot be cleared by any noise-clearance methods. At the same time the produced interference does not create any inconvenience to the participants of the negotiation thanks to the special headsets. The DRUID headset allows users to hear each other with crystal quality. Each headset can be adjust the level of microphone and earphone for the individual user and environment.- Professional system for protecting speech between up to 6 persons
- Expansible participants by connecting another unit with the optional cable
- Protects against all known methods of listening devices – All types of radio microphones, stethoscopes, voice recorders, passive resonators and wired microphones, etc.
- Absolutely harmless – no microwave reflections or ultrahigh sound noise
- Portable Design – supplied in a plastic carry-case it can be easily prepared for use
- DRUID provides a much higher level of protection than a white-noise generator.
Acoustical white noise does not jam digital voice recorders completely even at a high volume. - The system can be used in any situation
- Power Source: 110 V~220 V AC, an internal rechargeable battery (can work for up to 4 hours without mains supply)
- Type of noise: Distortion+Reverberation in a random sequence

Niose Generator MNG-300 Rabbler
It functions on the principle of speech-like noise, which in most cases has proven to be more reliable when compared to white noise.The speech-like noise used in the MNG-300 Rabbler, has been put together using real human conversations and voices, making it similar to the “rabble” in public places.The device is portable, small – cigarette pack sized, and easy to use.The Rabller renders the following listening devices useless:
- Voice Recorders
- Radio Microphones
- GSM/3G Bugs
- Body-carried Video Cameras, Watches, Ties, etc…(jamming of acoustics)
- Wired Microphones
