NOISEBOX® P1

A portable NoiseBox that protects your meetings against eavesdropping and recording via mobile devices, wherever you are!

NoiseBox P1 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 P1 solves this problem and easily protects your meetings from eavesdropping, even if you need to hold mobile meetings when portability is a requirement. Place all devices with a microphone, such as laptops or mobile phones, in NoiseBox P1 and activate it. If you like, you can connect phones or tablets to USB ports in the NoiseBox for charging.

NoiseBox P1 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. NoiseBox P1 is primarily designed for situations where protection against eavesdropping is desired in a portable format, e.g., during interrogations in the field. NoiseBox P1 has space for several phones as well as the occasional tablet.

NoiseBox blocks both camera and microphone recording efficiently, without risk of damaging the mobile device.

ultra

NoiseBox does not use ultrasonic technology, that may cause discomfort and fatigue in humans or harm animal hearing.

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.

The ORIGINAL anti-eavesdropping system​

NoiseBox suppresses all microphones

NoiseBox suppresses all microphones on the device independently of their placement on the unit.

NoiseBox do not interfere

NoiseBox do not interfere with the function of hearing-aids, and does not contravene any laws.

The NoiseBox  is the ORIGINAL anti-eavesdropping system with wide-spectral noise algorithms, that together with highly efficient dampening that also blocks camera recording,  is the superior alternative to other technologies such as ultrasonic jammers. Apart from human discomfort and fatigue that the ultrasound can create, these high frequency signals also can disturb hearing aids in proximity to the unit and can damage animal hearing. 

Ultrasonic technology can be dangerous

Many side effects of the ultrasonic technology is
due to the extreme sound pressure levels needed
for total overloading of the mobile phone
microphones, thus guaranteeing that no recording
of sound is possible. Microphones used in mobile
devices require over 150dB SPL to saturate and this
is equal to the sound of a jet powered aircraft at a
distance of 25 meters.

Ultrasonic technology can fail

Ultrasonic technology requires the user to correctly place their device in the ultrasonic field. Any deviation from this will allow eavesdropping. As
the camera of the unit is not disabled by ultrasonic waves, video with lip movement visible, can still be recorded and easily translated by talent or software.

NoiseBox P1 is designed for durability

NoiseBox P1 is built to withstand both wet and demanding environments. The case is IP 67 rated and constructed of impact-resistant polypropylene, which is extremely resistant to high-intensity impact.
