Protects your meetings against eavesdropping and recording via mobile devices!

NoiseBox W1 keeps your discussions private.

Any smartphone, tablet or laptop can be used with a suitable app for eavesdropping on everything that its microphone can pick up. This even applies when the device is in sleep mode. NoiseBox W1 solves this problem and easily protects your meetings from eavesdropping. Place all devices with a microphone, such as laptops or mobile phones, in NoiseBox W1 and activate it. If you like, you can connect phones or tablets to USB ports in the NoiseBox for charging.

NoiseBox W1 is the result of a request from the Swedish Police and Swedish Armed Forces for better protection against eavesdropping via smartphones. They have tested it and found it very useful. Since 2012, thousands of NoiseBox® units have been delivered to Swedish and foreign authorities and businesses. The stylish box in solid beech or oak is handcrafted in Sweden and fits nicely in all conference rooms. There is space for several phones as well as the occasional tablet.

NoiseBox® is based on advanced sound algorithms developed by Marenius.

NoiseBox has integrated speakers with specially developed electronics that produce wide-spectral acoustic noise. This noise effectively blocks the microphone in phones or other audio-recording devices placed inside the NoiseBox. This enables phones to be turned on during confidential discussions without the risk of eavesdropping. Should a phone ring, the ring tone can still be heard outside the NoiseBox, preventing important calls from being missed, and if you like, the phones can also be charged while in the NoiseBox via 4 USB ports inside the device.

NoiseBox W1 is available in different materials.

Different materials provide different expressions. For the NoiseBox to perfectly suit its surroundings, whether a conference room or office, most models are available in two different materials. The technology inside the box and function are the same.
