SAFE-4
Counter Eavesdropping Safe Box (4 slots)
The Secure Island
Proactive Acoustic Defense. Zero Signal Interference. Total Confidentiality.
Next-generation audio protection.
The SAFE-4 is a next-generation audio-protection system designed to stop unauthorised recording, streaming, or voice capture during critical discussions.
Using advanced ultrasonic microphone-jamming technology, SAFE-4 ensures your conversations remain private—without blocking mobile signals or disrupting connectivity.
Perfect for boardrooms, control centers, research facilities, or any environment where information security is paramount.
1. The Challenge: The Pocket-Sized Spy
Every smartphone in a high-level meeting is a potential eavesdropping station. Even when “locked,” modern mobile devices can be remotely activated to record audio or stream live conversations without any visual indicator to the owner.
Traditional Faraday bags or “phones in the hallway” policies disrupt connectivity and create operational friction. You need a solution that protects the conversation without isolating the team.
2. The Solution: Proactive Ultrasonic Defense
The SAFE-4 is a Counter-Eavesdropping Safe Box that utilizes proprietary Ultrasonic Mixing Technology to create an impenetrable acoustic barrier. By placing up to four smartphones into the SAFE-4’s designated “Security Island,” the microphones are effectively jammed with imperceptible noise.
- Safe & Senseless: Our ultrasonic technology is completely inaudible to the human ear and emits no electromagnetic radiation. It effectively blocks recording software without interfering with the phone's hardware.
- Stay Connected: Unlike a Faraday cage, the SAFE-4 does not block cellular signals. Participants remain online and can receive emergency calls or SMS alerts, while their ability to "listen" to the room is physically disabled.
- Automatic Protection: Designed for "zero-touch" operation. Simply place the devices in the slots, and the proactive defense begins.
3. Why the SAFE-4 is the Boardroom Standard
While consumer-grade "phone boxes" offer basic privacy, the SAFE-4 is a tactical instrument built on Acustek's 15-year heritage of supporting government and corporate security.
