At present, with the proliferation of smart phones and the improvement of recording technology, mobile phone recording has become more and more convenient, but this kind of convenience and popularity hides a huge danger. Many people have been blackmailed or even ruined because of a small recording; many companies have also gone bankrupt because their trade secrets have been recorded; even some government departments have been maliciously recorded in the process of handling their business, causing extremely bad social impact.
Danger, where is it lurking?
The leadership office is undoubtedly one of the hardest hit areas for recording leaks. Every leader faces the danger of being recorded by some unkind subordinates almost every day.
Leadership Office Environment
Negotiation room. Shopping malls are like battlefields. Behind every lively chat and laughter, there is a prepared deadly crisis.
Negotiation room environment
meeting room. For national security organs or departments such as the military, the Public Procuratorate and Judicial Department, and the Bureau of Secrecy, information confidentiality has always been a top priority. Once hostile forces or criminals steal state secrets through recording, the consequences will be disastrous.
meeting room environment
Petition Room. The petition window is a place to express appeals, but it does not rule out that individual people with ulterior motives deliberately make troubles through recording to create negative effects.

Of course, there are still many occasions where there is the risk of recording leaks. After all, now is the era of pervasive information. Any carelessness may cause immeasurable disastrous consequences.
Crisis is everywhere, how to prevent it?
In order to solve the problem of recording leakage, the L7B recording jammer developed by Shenzhou Mingda, based on the FPGA-based ultrasonic noise algorithm, emits ultrasonic waves with random noise that the human ear cannot perceive. When recording on digital devices such as mobile phones, these The noise and the sound of normal conversation are recorded into the digital device together, making the recorded audio invalid. The audio information in the captured video also has the same interference effect. Because the noise with ultrasonic noise is randomly generated and cannot be restored, it is disturbed The subsequent audio cannot be restored, thus ensuring that the original information is not leaked and spread.
