PROSAFE PREMIUM – Premium Acoustic Safe

The “Acoustic Safe” system 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.
Available modifications for Prosafe Premium and Prosafe Mini Premium Acoustic safes:

  • With solid lid,
  • With transparent lid,
  • With USB,
  • With transperant lid and USB,
  • With EMI shielding.

The Acoustic safe could also be EM (electromagnetic) Shielded (option). In this case the devices in the Acoustic safe are completely blocked and they are not connected to the mobile network (they lose connection to the mobile operator network, with Bluetooth handsfree, smart watches, Wi-Fi devices).
The EMI Shielded Acoustic safe blocks all standards below:

  • 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.

User-friendly: Put mobile phone in the Prosafe, switch the device on (adjust the sound level and type) and close the lid. The devices in the box don’t have audio and video access to the conversation and it is not possible to record it.
With the device with transparent lid, in the same time, you can hear and see if someone calls you and decide whether to accept the call or not. Thus, you don’t have to leave the mobile phones outside the room, switch them off or remove the batteries.

* Please note that the lid opening system may vary
