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. Prvo vprašanje, ki ga je treba upoštevati, je, ali je mogoče najnovejši model snemalne opreme zaščititi. Na primer, najnovejši modeli iphone, iphoneX/XR/XS/max itd. Kot vsi vemo, je bila trenutna snemalna oprema zasnovana z zmanjševanjem hrupa in filtriranjem tako v programski kot strojni opremi, kar zahteva, da je snemalni ščit tehnično integriran. te najnovejše snemalne opreme. Prav tako je lahko dobro zaščiten, da se šteje za kvalificiran izdelek, kar je treba upoštevati pri izbiri izdelka.

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. Ali je lahko zaščiten z vseh zornih kotov? Številni moteči na trgu imajo očitno slabost, to je, da je učinek zaščite mogoče doseči le, če je snemalni motelec obrnjen proti dvigu snemalne naprave (kot je mobilni telefon, snemalnik zvoka itd.), ko se dvigne in motilec snemanja tvori kot. In postopoma narašča, zaščitni učinek bo postopoma oslabel. Ko doseže 180 stopinj, večina snemalnih ščitov nima zaščitnega učinka. To je razmeroma podroben in relativno strokoven problem. Tisti, ki nimajo izkušenj, ga težko razumejo. Za ponazoritev uporabljamo naslednji diagram:
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.
