Ultrasonic Mixing Technology
Based on CPLD/FPGA Chip embedded with encrypted algorithm, it generates ultrasonic mixing data model and exports ultrasonic signals, forming a harmonic effect to deceive the recording device. The microphone/pick up can only receive the harmonic ultrasonic signal generated by jammer, can not pick up the normal voice signal.
Safe, Silently and Undisturbed
Thanks to ultrasonic microphone jamming technologies, there is no audible noise or electromagnetic radiation. This technology does not damage cell phone hardware, nor does it block any calls, SMS, or other network communications.
