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. Първият въпрос, който трябва да се разгледа, е дали последният модел записващо оборудване може да бъде екраниран. Например, най-новите модели на iphone, iphoneX/XR/XS/max и т.н. Както всички знаем, сегашното оборудване за запис е проектирано с намаляване на шума и филтриране както в софтуера, така и в хардуера, което изисква щитът за запис технически да се интегрира това най-ново оборудване за запис. Също така може да бъде добре защитено, за да се счита за квалифициран продукт, което трябва да се има предвид при избора на продукт.
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. Може ли да бъде екраниран от всички ъгли? Много устройства за заглушаване на пазара имат очевиден недостатък, тоест екраниращият ефект може да бъде постигнат само когато заглушителят на записа е обърнат към пикапа на записващото устройство (като мобилен телефон, диктофон и др.), след като звукът и смущенията за запис образуват ъгъл. И постепенно се увеличава, екраниращият ефект постепенно ще отслабва. Когато достигне 180 градуса, повечето екрани за запис нямат екраниращ ефект. Това е относително подробен и относително професионален проблем. За тези, които нямат опит, е трудно да го разберат. Ние използваме следната диаграма, за да илюстрираме:
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.
