Product Description

Product Description

Personal Voice Information Prevention System

Sonar tape noise-proof recording-shielding system is a highly integrated high-tech security protection product, based on the sonar ultrasonic band noise algorithm of FPGA. It adopts multi-frequency superimposed aerial spiral acoustic interference technology, which is at the world's advanced level.

When criminals use recording equipment to record, the recording shield will produce random noise signals, which can produce suppressive interference on voice signals, so that the recording equipment can only pick up noise information, but can not distinguish voice information, thus ensuring the security of meetings, conversations, and personal voice information.


Application Occasions
Sonar anti-recording shielding system is a highly integrated high-tech security protection product independently developed by our company. When criminals use recording equipment (such as mobile phones, pens, recorders, etc.) to record your voice, the anti-recording shield will produce random noise signals, which can produce suppressive interference on voice signals, so that the recording equipment can only pick up noise information, but can not distinguish voice information, thus ensuring the security of voice information. It is widely used in the leadership office, confidential meeting room, operation room, business negotiation room and other places where recording is prevented.
