Recording blocker to prevent illegal recording artifacts!
In our lives, we don’t want to be overheard and recorded, whether it is a company meeting, an old friend’s conversation, or a dinner table conversation. The anti-recorder can solve the risk of being recorded. 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 microphones in digital devices such as mobile phones and voice recorders will receive it. 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 recording muting device is an instrument that shields the recording. With the rapid development of information in today’s society, the issue of voice information leakage is a problem that is difficult to solve in the world. People’s normal conversations are recorded silently and reprocessed out of context to become a means of coercion by people with ulterior motives, which are related to national security. Important information is illegally recorded and disseminated, becoming a security hazard!
When the recording muting device is recording, the recording muting device will generate a random noise signal, which can produce suppressive interference to the voice signal, so that only noise information is picked up by the recording device, and the voice information cannot be distinguished, thereby ensuring the voice information Security. Widely used in: leadership offices, confidential meeting rooms, military war rooms, business negotiation rooms and other places that prevent recording.
Equipment principle: By emitting ultrasonic waves with random noise that human ears cannot perceive, when digital devices such as mobile phones are recording, these noises are recorded into the digital device together with the sound of normal conversation, making the recorded audio invalid. The audio information in the video also has the same interference effect. Since the noisy ultrasonic noise is randomly generated and cannot be restored, the audio after the interference cannot be restored, thus ensuring that the original information is not leaked and spread.
