ULTRASONIC SPEECH PROTECTION

At the core of the SEC-25's effectiveness is its ability to generate a highly complex ultrasonic noise pattern that directly interferes with the microphone’s diaphragm. This ultrasonic interference is inaudible to the human ear, but extremely disruptive to recording equipment. As a result, any attempt to capture audio in the jammer's protected zone results in garbled, unusable recordings—effectively safeguarding sensitive conversations and confidential discussions.

What sets the SEC-25 apart is its customizability. We offer tailored configurations to meet specific client needs, including custom-designed ultrasonic speaker arrays that can be optimized for different room sizes, acoustic environments, or concealment requirements. Whether you need discreet integration into furniture, directional jamming for targeted coverage, or 360-degree protection for larger meeting spaces, the SEC-25 can be adapted accordingly.

Ideal for boardrooms, government facilities, R&D labs, legal offices, and other environments where audio privacy is critical, the SEC-25 offers a proactive defense against modern eavesdropping threats. It is a crucial component in any comprehensive Technical Surveillance Countermeasure (TSCM) strategy, delivering peace of mind in an age of increasingly sophisticated surveillance technologies.

 Ultrasonic Jammer Installation for Audio Protection

To prevent unauthorized audio recordings, ultrasonic jammers will be strategically installed throughout the main desk area. The setup includes:

• Four ceiling-mounted loudspeakers positioned above the visitors’ chairs to provide comprehensive coverage. 
• Six compact units mounted discreetly under the table, using 10 to 16 ultrasonic sensors for maximum effectiveness.
• Two 360° desk-mounted speakers to ensure full-range ultrasonic interference directly at the point of conversation.
   

This configuration is designed to safeguard sensitive discussions by neutralizing recording capabilities of nearby microphones.

 Ceiling Noise Generator Installation for Enhanced Audio Security

Due to the complexity of inspecting above-ceiling spaces before each meeting—an area often targeted for hidden listening devices—we recommend installing a noise generator paired with ceiling-mounted loudspeakers. This system will emit targeted noise above the ceiling to disrupt potential eavesdropping devices.

A pre-installation test will be conducted to ensure the noise does not interfere with activities inside the office. The system can be configured to operate continuously or be activated as needed, providing flexible and effective audio protection.
