EMI Shielded Acoustic safe

The Acoustic safe is fully developed by PROFISEC Ltd.

The “Acoustic Safe” system developed by Profisec EOOD is a soundproof box with an audio generator of various noise signals, designed to block/ prevent the audio access from mobile phones/tablets, recorders, etc. (electronic devices that have a microphone) and providing complete protection against eavesdropping during meetings, conferences, confidential conversations or situations.

The box successfully prevents real-time transmission or recording of audio and video from the conversations.

In the electromagnetically shielded acoustic safe – in addition to the audio access of the devices being completely blocked, they also have no connection to the mobile network, Wi-Fi, Bluetooth, etc.

 

TECHNICAL CHARACTERISTICS:

• Acoustic attenuation- >=35 dB

• Acoustic jamming- >=50 dB (inside the box)

• It generates several types of sound/ noises
• Blocks the following standards:

CDMA, 2G, 3G, 4G, 5G; as well as the upcoming 6G; DECT; ISM radio bands; WiFi- 2,4 GHz, 5 GHz; as well as WiFi7; Bluetooth;

• It provides around 35 dB attenuation with a frequency range from 400 MHz to 6500 MHz.
• It reliably blocks the operation of all wireless channels of the mobile phones and the connection to the base stations.
• If there are powerful emitters near the safe, it is possible to get a connection with the devices inside. As the distance between the transmitter and the safe increases, the connection will be lost.
• For powerful Wi-Fi routers, the distance at which a reliable connection can be established is up to 2.5 m.
• For powerful Bluetooth transmitters- the distance is up to 1.5 m.
• Smart watches, fitness bands, hands-free and other similar devices cannot establish a reliable connection regardless of the distance.

• output power- 350mW;
• loudspeaker- 36 ohm, 500mW
• Consumption at max. noise level- no more than 35mA
• Adjusting the noise level- smoothly with control knobPower supply:

• • External power supply- 12V- enables continues work of the Acoustic safe
  • Power- 9V 6F22 non-rechargeable battery or NiMH accumulator battery in battery holder (optional)
  • Combined- external 12V power supply and 9V rechargeable battery, which is also charged at the same time. Automatic battery switchover when external power supply fails (e.g. power outage).
