A Silent Fortress Against Eavesdropping

Imagine a shield that doesn’t just block but obliterates the ability to record your voice. The PJ-310 harnesses ultrasonic waves in the 24–26 kHz range to disrupt the microphone diaphragms of any recording device in its path. By severing the link between sound and signal at the source, it renders smartphones, spy-grade laser microphones, and even seismic sensors powerless. This isn’t just interference—it’s total audio lockdown.
