F-12 Anti Recording Microphone Monitoring Eavesdropping Ultrasonic Sound Wave Generator Prevention Guard

High-Power Ultrasonic Sound Wave Generator Protection (8m Range)

The F12 360° Anti-Recording Jammer is a professional-grade security device designed to safeguard sensitive conversations against unauthorised audio surveillance. Utilising an advanced ultrasonic array, it creates a silent acoustic shield that renders microphones—including those in smartphones and digital recorders—incapable of capturing intelligible speech.

Key Features & Technical Specifications

• 360° Comprehensive Coverage:

  Equipped with 66 ultrasonic transmitting heads, the device provides full-perimeter protection. It effectively intercepts mobile phone recordings, digital voice recorders, and video-based audio capture from all angles.

• Ultrasonic Low-Frequency Interception:

  The F12 uses a sophisticated mix of high and low-frequency ultrasonic waves. This technology targets the microphone's diaphragm directly, creating a "bass" masking effect. The interception is non-recoverable, meaning even advanced forensic audio software cannot reconstruct the conversation.

• Extended Blocking Range:

  Offers a powerful suppression radius of up to 8 metres, making it suitable for large offices and executive boardrooms.

• Discreet Operation:

  Designed to work below the threshold of human hearing, the device operates silently, allowing for natural communication without alerting others that a counter-surveillance measure is active.

• High-Capacity Battery & Endurance:

  Powered by a 9800mAh battery, the unit provides 2 to 4 hours of continuous operation. Integrated four-stage LED indicator lights allow users to monitor remaining power at a glance.

Applications

The F12 is engineered for environments where information security is paramount:

• Corporate & Legal: Confidential boardrooms, business negotiations, and private consultation rooms.

• Research & Development: Protection of intellectual property and trade secrets.

• Government & Education: Secure meeting spaces and examination halls.

• Mobile Security: Safe use within automobiles for private transit discussions.

Important Compatibility Note

Device Limitation: Please be advised that this product is not as effective with iPhone 15 series or newer versions. Due to the specific microphone hardware and filtering technology used in these newer Apple devices, the ultrasonic suppression is less effective.
