In the process of receiving customer inquiries, we found that some customers often confuse mobile phone jammers with recording jammers. Some people's needs are obviously to limit the use of mobile phones, but they think that only need to block the voice function of mobile phones can achieve Purpose. Another part of people's functional requirements are anti-monitoring and anti-stealing recording, but they think that they only need to block the mobile phone signal to achieve their goals. So the question is, what is the difference between a mobile phone jammer and a recording jammer? Are the functions of the two similar?

First of all, we can give a very clear answer: mobile phone jammers and recording jammers are not the same type of product. The technical principles and functions of these two products are very different.

What is called a mobile phone jammer in the conventional sense is actually a more accurate name: a mobile phone signal jammer. It refers to the application of messy and disorderly interference signals, that is, white noise, on the corresponding frequency bands of all mobile phone systems, and suppresses the interference through power, so that the normal communication between the mobile phone and the base station cannot be established normally due to interference. Connection, the final performance is that the mobile phone has no signal and no network. The impact of the mobile phone jammer on the mobile phone is to make the mobile phone lose the function of communicating with the outside world, voice calls and data transmission, sending and receiving text messages and other functions, but this does not mean that the mobile phone becomes a waste brick, except for external communication. Functions, the phone's original recording, photographing, video recording and other functions can still be used normally.

The working principle of the recording jammer is completely different from that of the mobile phone jammer. It does not use the method of transmitting wireless interference signals, which belongs to the application category of the acoustic field. The application scenario of using the recording jammer is also relatively simple, and the target is also very clear, that is, to shield all sound collection devices such as pickups within a relatively short distance, and electronic devices with the functions of pickups and pickup microphones There are many products, in addition to mobile phones, it also includes voice recorders, recording pens, microphones, walkie-talkies and so on.

Let me briefly talk about the biggest difference between a mobile phone jammer and a recorder: the mobile phone jammer only shields the mobile phone signal and limits the conversation and communication of the mobile phone. Once the mobile phone jammer is turned off, the original external communication function of the mobile phone will be restored. The stored data, including video data, etc., can also be transmitted or sent externally. The function of the recording jammer has a certain destructive effect. It can make the recording device unable to collect effective sound. Even if it has a local storage function, the stored sound has lost its ability to be read.
