Recording jammer can effectively prevent malicious recording

　　At present, with the improvement of recording technology and the popularization of recording equipment, more and more criminals use various recording equipment to conduct illegal eavesdropping and recording activities. Recording blocker can effectively solve this problem. With the advent and application of recording jammer products, its limitations are slowly exposed, mainly focusing on the single direction, poor penetration effect, and poor shielding of conference rooms. It has been 7 years for Shenzhou Mingda. The research has finally achieved the latest technological breakthrough, and the company has made bold innovations in product application forms and principles.

　　There are many types of anti-eavesdropping equipment at home and abroad, but most of them use white noise to interfere. Although this method 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. Especially when the conversation time is long, it will bring discomfort to people and even affect the health of the interviewer.

　　The recording jammer is a highly integrated high-tech safety protection product independently developed by Shenzhou Mingda. When criminals use recording equipment (such as mobile phones, voice recorders, tape recorders, etc.) to record you, the recording muting device will generate random noise signals, which can produce suppressive interference to the voice signal, so that the recording equipment picks up only Noisy information, and voice information cannot be distinguished, thereby ensuring the security of voice information.

　　Product advantages

　　In the field of recording shielding equipment, there is only one device known to people. The recording shielding equipment is mainly for the obsolete tape recorders and a few models of voice recorders and eavesdroppers. For the current mainstream recording equipment, mobile phones, digital voice recorders, etc., no effect or poor effect. To this end, based on the information security technology accumulated over the years, our company has independently developed recording jammer products to meet the shielding function of mainstream recording equipment such as mobile phones and digital voice recorders to protect the safety of users' conversations.

　　Traditional technical defects

　　The traditional recording shielding technology scheme mainly uses a wide frequency range of random pulse sequences to carry out random interference. High-power high-frequency signals cause electromagnetic interference to the recording equipment, causing the input voltage or input current of the front end of the acoustic sensor to exceed the threshold of the acoustic sensor. Can not work normally and achieve effective voice blocking. This method is noise-free, but its main disadvantage is that it only interferes with analog recording equipment and is basically ineffective for new digital recording equipment. At the same time, high-power wireless electromagnetic signals will produce electromagnetic radiation, which is harmful to humans when used for a long time.

　　product competitive advantage

　　1. Support the shielding of various mainstream recording equipment.

　　2. In the working range of the recording blocker, the original voice information cannot be heard through the recording equipment.

　　3. In the working range of the recording blocker, the original voice information cannot be restored from the recording information when recording through the recording equipment.

　　4. No audible sound from the recording muffler during work.

　　5. The product can be disguised as daily office supplies, and can be customized research and development according to user needs, with strong concealment.

　　Product performance

　　1. Effective shielding distance: more than 2 meters (most recording equipment);

　　2. Effective shielding angle: greater than 150° included angle;

　　3. Effective remote control distance: more than 10 meters

　　4. Volume: 380*380*60(MM)
