WiNoise

This solar-recharged noise generator is designed to mask acoustic signal that can be sampled through windows.

RoomNoise

Ultrasound microphone interference device RoomNoise is a powerful tool whose purpose is to prevent any undesired tapping and recording using various tapping and recording devices that take advantage of a microphone.

MyNoise

is a compact device specifically designed for protecting your phone from wiretapping, and jamming recording devices.. The primary purpose of the device is to protect small or confined spaces such as pockets, bags, cupboards, drawers, table top etc.

MyBase

This product is intended to be used exclusively with the MyNoise product. When inserted into the stand, it creates a 360-degree circular ultrasound wave, which omnidirectionally interferes with the nearest sound recording device. At the same time, it provides protection against ceiling microphones.

WallNoise

WallNoise is designed for installation on the walls, the floors, the ceilings, and other building envelope surfaces, or for installation on technical wiring.

WiNoise Extender

WiNoise Extender is an external drive that can be connected to a WiNoise device and brings extended capabilities and performance of the WiNoise device.

OfficeNoise

Ultrasound microphone interference device OfficeNoise is a powerful tool whose purpose is to prevent any undesired tapping and recording using various tapping and recording devices that take advantage of a microphone, such as:

  • GSM and UMTS tapping
  • radio tapping
  • mobile telephones and PCs
  • acoustic recording devices in general
  • digital and analogue dictaphones
  • an appliance with a microphone that is placed in e.g. a button, tie, watch, video camera or any other item, or in empty space
How does the OfficeNoise interference device work?
  • The device works in such a way that it chokes up a microphone by appropriately generated ultrasound frequencies, thus limiting the input amplifier of the recording device.
  • The frequency combination is generated particularly to eliminate local spots with low ultrasound intensity, which increases the efficiency of the interference greatly.
  • Damage to the acoustic signal caused by the ultrasound affecting the microphone and subsequently limiting input circuits of amplifiers is of such a character that the original acoustic signal is impossible to retrieve from the recording.
  • The device setting can be optimized individually by a service technician via a USB port to suit any given space and area. If larger areas are to be covered, a larger amount of suitably positioned interference devices should be installed to achieve the correct efficiency of the system in a protected area.
  • OfficeNoise also has ultrasonic resonators on the underside and can be hung above the desk to better protect the entire room
OfficeNoise interference device can be combined with the following peripherals:

WiNoise that can be placed e.g. on windowpanes. A single piezoelectric element is capable of securing 25 square metres of the windowpane, thus making any tapping by a directional or laser microphone impossible.

WallNoise enables the wall of the secured space to vibrate in such a way that any taping or recording made over the wall by a stethoscope microphone is impossible. The Resonators are must be built into the wall and connected to a control device. For a standard separating wall, the efficiency of a Resonator is approx. 10 square meters. WallNoise can be also used to interfere with standpipes and vents.

The device has an integrated switch-off timer that switches it off after a set time has elapsed. Default setting by the manufacturer: 2 hours.

The device can be upgraded by a remote wireless control module that can be used to switch the system on and off.
