Recording jammer, effectively prevent mobile phone recording!

　　Afraid of incomplete shielding? The signal environment is complicated, and the budget is not enough? Afraid of being destroyed and the machine's lifespan is short? Just want to shield one signal, afraid of affecting other frequency bands? Afraid that the jammer will be discovered by others? Afraid that the jammer is too ugly to affect the indoor environment ?

　　At present, there are few types of anti-recording and eavesdropping products at home and abroad, only interference shielding through noise. Although there is a certain interference effect, the effect of interference shielding recording and eavesdropping is not ideal. Some of them use ultrasonic interference, but they are large in size and interfere. The distance is short, the working hours are short, and the noise is loud, which can make people feel dizzy and easy to be found.

　　When recording on digital devices such as mobile phones, these noises are recorded into the digital device together with the sound of normal conversations, making the recorded audio invalid and the interference effect is relatively successful. If you don't want to be recorded by others while you are talking, using a recorder jammer to interfere with the recording is a good choice. After using the recording blocker, when playing the audio information recorded by the recording device, only the "buzz" noise can be heard, and basically no voice message can be heard. Compared with similar products, its shielding distance is longer.

　　Because the current recording pen was developed and manufactured, this point has been taken into account, and the anti-interference performance is much better than the recording products of previous years. I remember a test many years ago. When someone recorded a sound on a modern Korean voice recorder, as long as there was a 40mm diameter magnet on the side, it could interfere with the normal recording of the recorder, resulting in the final recorded sound. The influence of the magnetic field becomes blurred. If there is a small motor on the side, the effect of interfering with the recording is even stronger.

　　Recording jammer interferes with various recording equipment such as mobile phones, voice recorders, and eavesdroppers. It has the characteristics of good shielding effect, high security, multiple application scenarios, customizable shapes, and no electromagnetic radiation. Compared with related products at home and abroad, it has great advantages in terms of shielding effect, safety, practicability and concealment. Applicable occasions: It can be used in offices, conference rooms, inquiry rooms, courts, and mobile offices. It can effectively solve individuals, enterprises, government agencies (such as the public security system, the military, the disciplinary committee...), etc., and can also be implemented according to customer needs custom made.

　　There are many devices used in recording jammers. The basic technical principles are divided into two categories. One is the use of white noise technology, and the other is the ultrasonic interference technology. The recording jammer developed by Shenzhou Mingda uses ultrasonic interference technology. The information of various brands of mobile phones and recording equipment that have been on the market in the past two years is added, which has a very obvious effect on new recording equipment and mobile phone recording.

　　Information security is no small matter. Now people are paying more and more attention to how to avoid and prevent the behavior of being recorded. In the era of advanced high-tech products, the technology of eavesdropping equipment has also been effectively improved. Nowadays, there are various types of eavesdropping equipment, some of which are very small in shape and cannot be detected at hidden corners. Eavesdropping devices often appear in hidden areas such as the bottoms of tables, flower pots, keyboards, and paper pumps in hotels, conference rooms, and important people’s meeting places, causing people a lot of trouble.
