  The recording jammer may be very unfamiliar to most people. Many people do not know or even have heard of it. In fact, this is normal. Because it is generally believed that recording jammers must be used in some professional scenarios to prevent illegal recordings, such as business talks, confidential meetings, military talks and other high-level security scenarios. In fact, recording jammers have gradually entered the market. In the life of ordinary people, as long as it is a conversation scene, it may be used.

What is an anti recorder?

  When you are in a company meeting or business negotiation or talking with old friends, you don't want the content of the conversation to be recorded and leaked. A recording jammer can help you. You only need to turn on the switch button, and the recording jammer will emit ultrasonic waves that exceed the threshold of human hearing and are harmless to humans. Using our self-developed ultrasonic noise-banding algorithm, the microphones in digital devices such as mobile phones and voice recorders will receive them. Due to the influence of the recording jammer, the sound of normal conversation is drowned in random noise, and the post-recording processing algorithm is also difficult to restore, thus protecting the content of the conversation from being leaked at the source.

  The working principle of the recording jammer

  The recording jammer emits ultrasonic waves with random noise that cannot be perceived by the human ear. When a digital device such as a mobile phone is 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 ultrasonic noise is randomly generated and cannot be restored, the disturbed audio cannot be restored, thus ensuring that the original information is not leaked and spread.

  Advantages of recording jammers:

  Can effectively interfere with digital devices such as mobile phones and voice recorders. The anti-recording effect is at the world's advanced level, which can effectively ensure that conversations are not recorded, thereby ensuring information security.

  The protection range of a single recording jammer is similar to a cone-shaped space, the interference range is about 15 square meters, and the interference distance to most digital products such as mobile phones 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 recording jammer gps can only be received by digital products such as mobile phones and recording pens but cannot be heard by people. Compared with other anti-recording devices, there is no humming noise, and it can quietly guard the conversation environment.

  The anti-recording device is only effective for digital products such as mobile phones, and does not interfere with people. Because the human body does not receive ultrasonic waves, the recordings recorded by mobile phones are all noise, but people cannot hear them, so it does not affect normal conversation and communication, and even cannot detect the anti-recording device. The recorder is working.
