Two high-quality speakers ensure perfect sound distribution in the room, guaranteeing optimal protection in all directions. The practical case in which the kit is stored is not only an aesthetic accessory, but also a functional solution for easy transportation and safe storage. Whether you are a security professional, a businessman or just someone who wants to protect their privacy, the DNG-KIT1 will give you peace of mind and assurance that your sensitive information will remain safe. Let yourself be surrounded by sound protection that will give you freedom and security in a world where privacy is a rare commodity.

The high-end 3-channel white noise generator DNG2300 is an innovative device designed to generate high-quality white noise for various types of eavesdropping: wireless microphones (flat microphones), dictaphones, hidden wireless cameras, eavesdropping performed with a mobile phone and before eavesdropping performed with a contact microphone (stethoscope) and means using laser technology for sound sensing. With three independent channels, it allows users to combine different sound frequencies to customize the atmosphere according to their needs. The DNG2300 features intuitive controls and a wide range of settings, ensuring easy and efficient use. It is well-known that sound permeates through walls, doors, water, windows and other constructions as well as through voids, cavities and ventilation shafts. This property of materials makes it possible to intercept conversations conducted within a premises with the help of highly sensitive contact microphones (electronic stethoscopes), window laser systems or conventional microphones without entering the target area. Wall contact microphones can pick up vibrations from the plumbing, structures, walls, windows, doors, floors, ceilings and more. The listening device may be in an adjacent room, or even several floors or rooms away attached to a wall, pipe or other fixture. Cavities such as air ducts, ventilation shafts or other voids can be used for intercepting sound from an adjacent premises with a help of conventional microphones. Window laser systems are able to “read” conversations from the premises by sending visible, or invisible, infrared beams to the glass and extracting the sound vibrations from the reflected rays. The DNG-2300 generator, together with its transducers and speakers, counteracts all the above mentioned methods of listening by creating powerful, non-filterable interference on the structure of a building and within its voids. While transducers inject their generated noise into surfaces and structures, stopping the distribution of sound through them, the role of a speaker is to fill voids, cavities and ventilation shafts with audio interference to prevent leakage of sound through the air.

Features DNG2300:

• Creates powerful protection against the leakage of all types of vibro-acoustics by injecting non-filterable noise into surrounding structures and cavities
• Suppresses wall contact microphones, window laser systems and wired microphones inside walls, voids and ventilation shafts (air ducts)
• Is a key part of the protection system which also includes wire-connected transducers and speakers
• Generates white noise – the output interference is evenly distributed through the spectrum of a human’s voice
• Has 3 independent output channels: 2 x TRANSDUCERS and 1 x SPEAKERS
• All 3 channels have individual level adjustment
• Each TRANSDUCERS channel can feed up to 12 transducers (included) mounted on solid structures (concrete/cement/bricks) and up to
• 24 transducers on light structures (glass, pipes, drywall, wood)
• The SPEAKERS channel can feed up to 12 speakers
• The MUTE control input allows the user to turn off the speakers temporarily

The TD2300 vibroacoustic transducer is part of a complete counter surveillance protection system. It inducts noise into walls, floors, ceilings, windows and other surfaces of the building, preventing leakage of sound signals. To provide a sufficient level of protection the system consists of a number of transducers installed on different structures in the room and is connected to a generator.

Advantages:

• Attractive design, looks good in any interior
• High power output, combined with compactness
• Fits equally well on windows, walls and other structures
• The included mounting set makes it possible to install the transducer on any surface
• Passes most of the generated noise into the desired construction in the form of vibration, while also producing less audible interference
• The frequency characteristics optimally correspond to the spectrum of human’s speech
• Perfectly suited for the DNG 2300 white noise generator

Specification:

• Impedance: 4 Ohm
• Frequency response: 58 Hz – 12 kHz
• Power: 10W
• Weight: 252 g
• Dimensions: 56×27 mm

The SP2300 omnidirectional speaker is part of a complete counter surveillance noise generators protection system While transducers inject their generated noise into surfaces and structures, stopping the distribution of sound through them, the role of the speaker is to fill voids, cavities and ventilation shafts with audio interference to prevent leakage of sound through the air.

Prevents the following ways of listening:
• Listening with the help of a wall stethoscope placed behind the construction which is adjacent to a cavity in the room (typically from the floor above, behind a dropped ceiling)
• Leakage of sound outside the target room through voids/cavities (for example, through ventilation shafts or common holes for the pipes of a heating system)
• Placing a wired microphone in a void or cavity
• Hiding a covert surveillance device in a void or cavity

The SP2300 speaker, when connected to a white noise generator, will create efficient interference for all the above mentioned kinds of eavesdropping.

Specification:

• Power output: 4 Ohm
• Resistance: 24 Ohm
• Dimensions: 110×80 mm
• Weight: 360 g
