Maybe you haven't realized the harm of information leakage and data loss, or you think your information is not so valuable and will not be used by others. But now, leaking secrets has undoubtedly become a common term. The outflow of information such as recordings on mobile phones not only easily reveals personal privacy, but may also encounter scams, which may seriously even endanger national security. From ancient times to the present, the methods of stealing secrets, eavesdropping, and secretly taking pictures have risen step by step with history. The scope of monitoring has risen from the original eavesdropping and secret shooting of individuals to various secret-related areas such as politics, military affairs, and meetings.
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 at 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 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.
Anti-recorder features
Our self-developed FPGA-based ultrasonic noise algorithm 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 the conversation is not recorded, thereby ensuring the safety of information
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 about it in this space. Recorded by others
We tested the iPhone, Huawei, Xiaomi, OPPO, VIVO, Samsung, Nubia, Meizu, Nuts and other new and old models of mobile phones. The interference effect is good. We tested the recordings of Sony, Samsung, Newman, Lenovo, Olympus, etc. Pen, good interference effect
The sound waves emitted by the anti-recorder can only be received by mobile phones, voice recorders and other digital products but cannot be heard by humans. Compared with other anti-recorders, there is no buzzing noise, and it can quietly guard the conversation environment without being disturbed.
