Information security is no small matter. Now people are paying more and more attention to how to avoid and prevent the behavior of being recorded. In the era of advanced high-tech products, the technology of eavesdropping equipment has also been effectively improved. Nowadays, there are various types of eavesdropping equipment, some of which are very small in shape and cannot be detected when installed in hidden corners. Eavesdropping devices often appear in hidden areas such as the bottoms of tables, flower pots, keyboards, and paper pumps in hotels, conference rooms, and important people’s meeting places, causing people a lot of trouble.
When recording digital devices such as mobile phones, ultrasonic waves with random noises that human ears cannot perceive will be emitted. These noises are recorded into the digital device together with the sound of normal conversations, making the recorded audio invalid. Audio information also has the same interference effect. Since the noise with ultrasonic noise is randomly generated and cannot be restored, the audio after being interfered cannot be restored, thus ensuring that the original information is not leaked and spread. The sound waves emitted by the recording blocker 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 team has acoustics and electromagnetic experts, senior integrated circuit designers, senior product designers, etc. It is a high-quality professional team that can be customized according to the user's use place (such as clubs, hotels, private residences, negotiation rooms, etc.) Appearance of the product to meet the differentiated use needs of customers. Recording jammers are only effective for mobile phones and other digital products, and have no interference to people. Because the human body does not receive ultrasound, the sound recorded by mobile phones is noise, but people cannot hear it, so it does not affect normal conversation and communication, and even cannot detect the prevention. The recorder is working.
Recording blocker may be very strange to most people. Many people don't know or even heard of it. In fact, this is also normal. Because it is generally believed that the recording blocker must be used in some professional scenes to prevent illegal recording, such as business meetings, confidential meetings, military talks and other high-level confidential scenes. In fact, it is not the case. The recording blocker has gradually entered Ordinary people's life, as long as it is a conversation scene can be used. However, professional recording jammers are expensive, and buying unprofessional is a waste of emotions!
Nowadays, not only the courts need to shield audio and video recordings, but also to prevent them from being recorded commercially. With the popularization of digital products such as voice recorders and smart phones, the level of digital recording technology is gradually improving, and there are endless incidents of audio secret recording. From individual conversations between citizens, to business meetings within enterprises, and even important decision-making and confidential information of government departments may be stolen without knowing it, seriously threatening the security of individual and collective voice information.
