PRIME+ Speech Protector and Signal Jammer

It combines three privacy protection technologies

All portable electronics have built-in microphones that can be easily misused to record private conversations and confidential meetings. Thus, the competition can easily discredit you so that you lose your reputation and the trust of your customers. Protect your secrets and know-how with the PRIME+ Speech Protector.

The PRIME+ Speech Protector and Signal Jammer combines three privacy protection technologies:

Ultrasound Generator – Discrete Mode, Inaudible Protection

  • Highly efficient against digital recording devices and bugs
  • It also distorts recordings to useless noise

Acoustic Noise Generator – Audible Protection

  • Protects against stethoscope and laser microphones
  • Generates mixed voice that creates a sound barrier
  • It protects even from the most advanced forensic cleaning techniques

Signal Jammer

  • Disrupts mobile signal within the range of the jammer, including 2G, 3G, 4G and 5G signals
  • Blocks the use of Bluetooth and eavesdropping with wireless headphones
  • It cancels the two most used Wi-Fi frequencies

Three Protection Modes

Discrete Protection

  • Generates ultrasound and silent acoustic noise
  • This mode allows you to negotiate comfortably while protecting against most covert recording devices and bugs

High Protection

  • Generates both ultrasound and acoustic noise while interfering with the mobile networks in range
  • In this mode, it protects against high-quality voice recorders and location tracking

Maximum Protection

  • Generates ultrasound and loud acoustic noise
  • Provides maximum protection of confidential information even at the cost of reduced comfort during negotiations
