This recording blocker is an audio version of the recording blocker newly developed by our company recently. In view of the reason that the recording muffler produces a little noise when it is working, the recording muffler has no noisy sound when it is working, and can quietly guard the conversation environment and is not easy to be noticed.
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 don't want the content of the conversation to be leaked or made public, an anti-recording device 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 microphones in digital devices such as mobile phones and voice recorders will receive it. Prevent the influence of the recorder, so that the sound of normal conversation is submerged in random noise, and the post-recording processing algorithm is also difficult to restore, thus protecting the content of the conversation from being leaked from the source
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 security 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 various old and new models of mobile phones such as iPhone, Huawei, Xiaomi, OPPO, VIVO, Samsung, Nubia, Meizu, Nuts, etc. The interference effect was good, and we tested recordings from Sony, Samsung, Newman, Lenovo, Olympus, etc. Pen, good interference effect
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.
