Microphone Jammer

Product number: PKI 6685

Our PKI 6685 Microphone Jammer is designed to fully protect conversations prior to recording on devices with microphones such as mobile phones including smartphones, voice recorders, analogue and digital audio recorders and wireless and wireline microphones. The PKI 6685 Microphone Jammer generates a complex, structured ultrasonic signal that acts directly on the membrane of the microphone.
The complex, structured ultrasonic interference in the frequency range of 24 to 26KHz makes this application possible. For most people, the interference signal is practically inaudible from a distance of one meter to the PKI 6685 Microphone Jammer.
PKI 6685 provides on/off interference through a wireless remote control.
