As a brand-new high-tech product, the recording shielder has gradually entered people's field of vision. It can prevent illegal recording and protect the privacy and safety of your conversations in many occasions! The principle is: the recording shield sends out a The interference signal makes the pickup (microphone) of the sound acquisition device fail, so that it can only pick up the interference signal, but not the normal voice signal, thus achieving the purpose of voice shielding. After the jammer is turned on, the files recorded by the recording equipment are played with a "humming" sound and the content of the conversation at that time cannot be heard. This product is widely used in confidential meetings, high-end business talks, military meetings and other places to prevent illegal recording. There are many types and forms of recording shielding products on the market. How to choose a good recording shielding product has become a problem that needs to be solved.
So, what constitutes a useful and practical anti recording blocker product? According to the author's many years of investigation, a qualified product should follow the following points:
1. 최신 모델의 녹음 장비를 차폐할 수 있는지 여부가 가장 먼저 고려해야 할 질문입니다. 예를 들어, 최신 모델의 iphone, iphoneX/XR/XS/max 등. 우리 모두 알고 있듯이 현재 녹음 장비는 기술적으로 통합하기 위해 녹음 실드가 필요한 소프트웨어와 하드웨어 모두에서 노이즈 감소 및 필터링으로 설계되었습니다. 이 최신 녹음 장비. 또한 제품을 선택할 때 주의해야 하는 적격 제품으로 간주되도록 잘 차폐될 수 있습니다.
2. Whether the audio recording jammer will cause discomfort to the human body after it is turned on is a very important issue. The recording shielding device realizes shielding by emitting shielding signals. The frequency and algorithm used by different manufacturers of the shielding signal are very different. The frequency and algorithm determine people's feelings and shielding effect. According to the author's investigation, after many products start working There will be sharp or harsh sounds, which will make people feel uncomfortable. Such products should be avoided as much as possible.
3. 모든 각도에서 차폐가 가능한가요? 시중에 나와 있는 많은 방해 전파는 분명한 단점이 있습니다. 즉, 녹음 방해 전파가 녹음 장치(휴대폰, 음성 녹음기 등)의 픽업을 향하고 있을 때만 차폐 효과를 얻을 수 있습니다. 녹음 방해기는 각도를 형성합니다. 그리고 점차 증가하면 차폐 효과가 점차 약해집니다. 180도에 도달하면 대부분의 녹음 실드는 차폐 효과가 없습니다. 이것은 비교적 상세하고 비교적 전문적인 문제입니다. 경험이 없는 사람은 이해하기 어렵습니다. 다음 다이어그램을 사용하여 설명합니다.
As long as you keep the above three points in mind, and then choose a Audio jammer /noise generator that suits your usage habits according to your own situation, especially the characteristics of easy portability and flexible placement, for example, it can be placed in the car, on the desk, or Conference table, etc., you can refer to AL ASAR TECH's recording jammer products. Their products have the inspection report of the Ministry of Public Security and are regular manufacturers. You can pay attention to it, I believe that some people who have the need for conversation confidentiality should really choose a convenient, easy-to-use and practical recording shield to protect your conversation privacy.
