Counter Surveillance, General
Noise generator The Stealth DNG2300DTNThe 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

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

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.SKU: 5487FB8/28-8

The Protect 1206i is a new class of a counter surveillance device. Unlike all typical searching devices it can detect modern hidden bugs which use such protocols as Bluetooth and Wi-Fi. Such bugs, especially Bluetooth types, are practically undetectable by common RF detectors due to their very low transmitted power and a special type of modulation. The Protect 1206i uses a separate channel with a high, (2.44/5 GHz) frequency pre-selector to detect and locate Bluetooth and Wi-Fi with a much higher sensitivity. The unit also then processes the demodulated signal in order to identify which protocol has been detected.
In addition the unit can detect all types of conventional bugging devices (FM-modulated transmitters, digital transmitters, GSM-bugs, etc.) using its distinctive features:
- Active correlation: inspecting dangerous places with the probing sound impulses while watching the demodulation bar graph
- Recognition of type of digital transmission: GSM, Bluetooth, Wi-Fi, DECT
- 4 working modes: silent, sound, vibration and mixed
- Wide dynamic range thanks to the 16-segment bar graph

Ultrasonic Smartphone/ Voice recorder Jammer GTG-2060
The product GTG-2060 is a high-frequency signal generator with a special type of modulation, thanks to which it acts on circuits of electronic devices in which this signal, after being imposed, is processed in AGC circuits together with the useful signal, significantly exceeding its level and, accordingly, distorting it.
For impact on microphones, acoustic exposure using ultrasonic frequencies is used.
Such an impact does not interfere with the negotiation, but completely suppresses the effect of the speech signal by a large amount of ultrasound pressure.
The sound perceived by the microphone is converted into electrical oscillations, which are transmitted in one way or another to the corresponding devices for their reception and processing.
The axis of the main lobe of the radiation pattern of the microwave range generator installed in the power unit is perpendicular to the plane of each antenna unit, its width in the horizontal plane is about 80 degrees, and in the vertical one – about 60 degrees.
The axis of the radiation pattern of each ultrasonic transducer is about 60 degrees in the horizontal and vertical planes. Maximum range – up to 3 meters Type of interference: ultrasound, speech likeSKU: 5487FB8V
