Have you ever heard of a device that prevents recording and want to know why you use a recording jammer to prevent recording. Nowadays, modern technology is constantly changing our lives, so it is very important to understand some of the latest inventions in this field. Recording jammers are different from other equipment. Whether it is wired or wireless pickups and microphones, as long as they are capacitive pickups, they can be completely interfered by recording jammers.
The most effective way to prevent recording is to generate random noise signals through a recording jammer, which can suppress the voice signal, so that the recording device picks up only noise information, but cannot distinguish the voice information and cannot restore it from the recorded signal. Out the original information, thereby ensuring the security of the voice information. The recording jammer adopts security encryption processing, and effectively prevents post-recovery by mixing high and low frequency audio sources.
In addition, you should know the working principle of recording jammers on the market. At present, there are many types of anti-eavesdropping devices at home and abroad, but most of them are ultrasonic interference and white noise (to achieve anti-recording. Ultrasonic interference mode, ultrasonic is based on A sound frequency emitted by a frequency that is not perceivable by the human ear. It has no harm or impact on the human body, but it will cause huge interference to all equipment that relies on pickups to record sound. The frequency band it emits impacts audio and video equipment The pickup film of the pickup head causes irregular frequency fluctuations on the pickup film, so that the sound recorded by these devices is completely irregular noise.
Although white noise interference can achieve the effect of preventing eavesdropping in terms of interference effect, it is also a kind of noise pollution for all parties in the conversation. It will emit a great interference noise. If it is turned on for a long time, it will bring discomfort to people and even affect the health of the interviewer.
During use, the recording jammer will randomly generate ultrasonic noise signals and superimpose sound signals at the same time. This way, it can produce a good interference effect on the recording equipment, so as to achieve the effect of anti-eavesdropping. Its effective interference distance is within 5 meters, and it can be used in places with small spaces such as general meeting rooms or coffee shops.
If you need to keep your conversation safe at a certain time and get rid of the interference of recording equipment, you can choose MDPB-L7B recording jammer which can solve this problem well, thereby ensuring your safety and confidentiality. Product application places: confidential meeting rooms, public security bureau petition center, procuratorate reception hall, courts, negotiation rooms, offices and other places for private conversations
