Some legal elements collect important core secrets of our country’s politics, economy, military, science and technology. Illegal recording is one of the methods, especially in offices, confidential conference rooms, and places where recording is not allowed in the public security system, such as in courts. To detect whether people are carrying recording equipment, they can only use high-tech equipment to adopt technical precautions.
With the development of the information society, audio and video information is showing explosive growth and viral transmission. There is a risk that personal privacy, business secrets and other information will be leaked through conversations, especially how valuable conversation information can be protected. Content is not stolen by others?
When illegal recording endangers itself and national interests, it is time to say goodbye to information leaks. Shenzhou Mingda has been focusing on information security for 14 years. The newly developed L7B recording jammer has given itself a safe private space and escorted the security of national secrets. The product eliminates the high-frequency noise of the old equipment, and adds the information of various brands of mobile phones and recording equipment that have been on the market in the past two years, which has a very obvious effect on the new recording equipment and mobile phone recording.
The working principle of a recording jammer is to emit ultrasonic waves with random noise that cannot be perceived by the human ear. When recording on a digital device such as a mobile phone, these noises are recorded into the digital device together with the sound of normal conversation, making the recorded audio invalid. , It has the same interference effect on the audio information in the captured video. Because the noise with ultrasonic noise is randomly generated and cannot be restored, the audio after the interference cannot be restored, thus ensuring that the original information is not leaked and spread. .
Recording muting deviceWhen recording, the recording muting device will generate a random noise signal, which can produce suppressive interference to the voice signal, so that the recording device picks up only noise information, and cannot distinguish the voice information, thereby ensuring the voice information Security. Scope of application: confidential meeting rooms, public security bureau petition center, procuratorate reception hall, courts, negotiation rooms, offices and other places for private conversations.
