With the continuous improvement of recording technology, recording equipment is becoming more and more popular. Many criminals use various recording equipment to carry out illegal recording activities, which has a lot of impact on the daily work and life of administrative agencies, judicial agencies, enterprises and even individuals. People's normal conversations are recorded silently, and even some important information related to national security is illegally recorded and spread, which has become a security risk.
How to protect our conversation security? MDPB-L7B anti-recording device to understand, looks exactly like a speaker, based on the FPGA-based ultrasonic noise algorithm, can effectively ensure that the conversation is not recorded, protect your information security~
1. MDPB-L7B working 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 conversations, making the recorded audio invalid. The audio information also has the same interference effect. Because 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.
2. Four features of MDPB-L7B
01, good anti-recording effect
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.
02、Large range of action
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.
03, many action equipment
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, interference effect is good.
04、The quiet guardian
The sound waves emitted by the anti-recorder can only be received by mobile phones, voice recorders and other digital products. People cannot hear the sound. 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.
