PRIME+

360° Omnidirectional Ultrasound Jammer & Signal Jammer & Speech Protector

It combines three privacy protection technologies

All portable electronics are equipped with built-in microphones, which can be easily misused to record private conversations or confidential meetings. The PRIME+ Speech Protector and Signal Jammer addresses this by combining three advanced privacy protection technologies:

Ultrasound Generator

  • Operates in discreet, inaudible mode.
  • Highly effective against digital recording devices and surveillance bugs.
  • Recordings become unusable, producing only unintelligible noise.

Acoustic Noise Generator – Audible Protection

  • Protects against stethoscope and laser microphones, even against advanced forensic cleaning techniques.
  • Acoustic noise is created on the basis of the mixed voices.
  • When conducting live, in‑person meetings, we recommend pairing the Acoustic Noise Mix technology with the Solomon solution to achieve clearer, higher‑quality spoken communication.

Signal Jammer

  • Overwhelms commonly used Wi-Fi frequencies and cellular networks.
  • Blocks Bluetooth and wireless headphone eavesdropping.

Frequencies

  • Overwhelms cellular networks (including 5G and Wi-Fi 6).
  • Frequencies are customized for each country.

Universal Protection

The PRIME+ Speech Protector is designed to prevent unwanted recordings during meetings. It is ideal for securing offices, meeting rooms, and other spaces where sensitive information is discussed. The device is discreet and does not attract attention, as it has no external antennas.

For custom frequency configurations, please contact us. The product is sold in a special mode for government use.

We also offer a dedicated category of products for protecting mobile phones and devices against eavesdropping — “Signal & Anti‑Recording Phone Boxes.” These security storage boxes combine Faraday shielding with active signal jamming, block mobile and Wi‑Fi frequencies, and suppress microphone recording.
