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
- Any other Type of Audio Surveillance

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
– 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 ACSKU: 5487FB8/21 - Counter Surveillance, Surveillance
The Stealt SM2020
The Stealth SM2020 is the most advanced portable audio jammer and speech protection system which protects you against listening and known recording devices. The Stealth SM2020 creates sound barrier interference which masks your speech and any sound to be extremely difficult or impossible to extract the original content from the noise.
When it is used in the correct manner, The Stealth SM2020 will protect you from;
· Voice recorders(tape and digital)
· Microphones, wireless microphones
· Stethoscopes, laser listening device
· GSM/Buletooth/Wi-Fi transmitters, etc.
Main Functions
1. Sound Masking (Audio Jamming)
The 2 channel chaotic noise ( Distortion + Reverberation) in a random sequence secures your privacy and information from recent hi-tech speech extraction software.
· Main Speaker: 500 mW
This built-in speaker creates sound barrier interference against listening and recording nearby its location.
· Sub-Transducer: 700 mW x 2
This 2 special transducers (TRN600S) can be installed on window, wall, partition, ceiling and hard floor and create chaotic noise with random vibration depending on the output of noise to protect your speech from eavesdropping and listening.
2. RF Detector: 70 MHz ~ 3000 MHz
The Stealth SM2020 has built-in RF detector to detect any active wireless microphone or covert camera and warns with a beep sound or LED.
· Detection distance: up to 3 M (10 feet)
· Sensitivity control capability
Features
· Protects against all known methods of listening devices – All types of radio microphones, stethoscopes, voice recorders, passive resonators and wired microphones, etc.
· Portable Design – it can be easily prepared for use.
· Provides a much higher level of protection than a white-noise generator.
· The system can be used in any situation.
· The StealthSM2020 built-in RF detector gives an additional protection against nearby radio microphones and RF transmitters.
· Absolutely harmless – no microwave reflections or ultrahigh sound noise

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.
