Laser Wiretapping Blocking System - Remote Wiretapping Blocking 

DNG-2300 white noise generator  It is manufactured to protect against listening devices that cannot be detected by general methods. The device provides protection inside the room by emitting unfilterable noise to the surfaces. This noise, also known as 'white' noise, is transmitted to the surfaces with the help of the TD2300 transducers and OMS-2000 speakers in the device. The number of transducers and speakers depends on the room structure.

TD2300  Thanks to the transducers, the protection level of the generator is higher than in systems equipped with only loudspeakers. While transducers transmit most of the noise produced as vibration to the desired structure, they produce less audible interference. A slight noise will be heard in the protected area, but we will not need to raise your voice.

DNG 2300 protects you from the following threats

  • Laser and microwave surveillance systems using window reflections

  • Electronic stethoscopes (contact microphones)

  • Microphones embedded in walls or other structures

  • Other vibroacoustic information leak methods

How does eavesdropping work?

Vibro acoustic leakage is possible thanks to the ability of sound waves to penetrate walls, windows and other structures. Sound travels through some materials even better than air. For example, sound is a very good conductor and heating systems can be easily used to listen to conversations secretly. This principle is also used in electronic stethoscopes. Electronic stethoscopes capture speech-induced vibrations in walls, windows and other structures and convert them back into sound. These eavesdropping devices can be installed in adjacent environments or even several floors or rooms away from the target area in some way, with a common space or structure.

Protection principle

The DNG-2300 is able to 'block' the methods described above. This inhibition is provided with the help of special transducers. It is recommended to use the TD2300 device. The parameters of this device are optimal for many surfaces. TD2300  Since it is a highly effective device, only an insignificant part of the noise produced is dispersed into the air, while most of it is sent 'into' the structure as vibration. With the help of the bracket, the transducers can be mounted on almost any surface.

OMS-2000 versatile masking speakers can be used with the DNG-2300 device. The purpose of these speakers is for ventilation shafts, behind ceiling panels, etc. is to produce noise that cannot be filtered in areas such as
