With the frequent occurrence of recording leaks, recording muting devices have become a necessary product for voice information security protection, and how to buy a recording muting device is also very important. You must understand this point clearly before purchasing. A good recording jammer must have a good jammer effect. If there is no good shielding effect, it will lose the meaning of buying. It should also be clear about the location and scope of the shielding. Some irresponsible business tests only test a situation where the microphone is facing directly, and then claim how good the shielding effect is. That is completely wrong. Because in formal use, it is impossible for the recorder to shield the microphone of the recording device directly against your shield. That is to say, any angle of the recording device can be shielded within the shielding range.
When you want to have a safe conversation space, whether it is company meetings, old friends chatting or chatting at the dinner table, and you do not want the content of the conversation to be leaked or made public, an anti-recorder can help you get it done. You only need to turn on the switch button, and the anti-recorder will emit ultrasound that exceeds the threshold of human hearing and is harmless to humans. Using our self-developed ultrasound noise algorithm, the microphone in mobile phones, voice recorders and other digital devices will receive Prevent the influence of the recorder, thereby obliterating the sound of normal conversation in random noise, and the processing algorithm after recording is also difficult to restore, thus protecting the content of the conversation from being leaked from the source
The protection range of a single anti-recorder is similar to a cone-shaped space, and the interference range is about 15 square meters. The interference distance to most mobile phones and other digital products is more than 2 meters, which can form a safe space. Don't worry in this space Recorded by others. The sound waves emitted by the anti-recorder can only be received by digital products such as mobile phones and voice recorders but cannot be heard by humans. Compared with other anti-recorders, there is no buzzing noise, and it can quietly guard the conversation environment and is not easy to be noticed.
The working principle of the recording blocker is to emit ultrasonic waves with random noise that the human ear cannot perceive. When recording on a digital device such as a mobile phone, these noises and the sound of normal conversation are recorded into the digital device, making the recorded audio invalid , The audio information in the captured video also has the same interference effect. Because the noise with ultrasonic noise is randomly generated and cannot be restored, the audio after the interference cannot be restored, thereby ensuring that the original information is not leaked and spread .
