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. آیا می توان آخرین مدل تجهیزات ضبط را محافظ کرد یا خیر اولین سوالی است که باید در نظر گرفته شود. به عنوان مثال جدیدترین مدل های آیفون، iphoneX/XR/XS/max و ... همانطور که همه می دانیم تجهیزات ضبط فعلی با کاهش نویز و فیلتر هم در نرم افزار و هم سخت افزار طراحی شده اند که نیاز به یکپارچه سازی فنی محافظ ضبط دارد. این جدیدترین تجهیزات ضبط همچنین می توان آن را به خوبی محافظت کرد تا محصولی واجد شرایط در نظر گرفته شود که باید در هنگام انتخاب محصول به آن توجه داشت.
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. آیا می توان آن را از همه زوایای محافظت کرد؟ بسیاری از پارازیتهای موجود در بازار یک عیب آشکار دارند، یعنی اثر محافظ تنها زمانی حاصل میشود که دستگاه ضبط صدا رو به پیکاپ دستگاه ضبط (مانند تلفن همراه، ضبطکننده صدا و غیره) باشد، پس از پیکاپ و پارازیت ضبط یک زاویه تشکیل می دهد. و به تدریج افزایش می یابد، اثر محافظ به تدریج ضعیف می شود. هنگامی که به 180 درجه می رسد، اکثر سپرهای ضبط هیچ اثر محافظی ندارند. این یک مشکل نسبتاً دقیق و نسبتاً حرفه ای است. درک آن برای کسانی که تجربه ای ندارند دشوار است. برای نشان دادن از نمودار زیر استفاده می کنیم:
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.
