When selecting the timing of anti-eavesdropping equipment, more risks of passive leakage will be considered. Information equipment will have two ways of electromagnetic emission, one is radiation and the other is conduction. However, among these methods, It will be able to conduct relevant information through the power line or the communication line. At present, sound leakage is basically divided into two ways. One is unconscious leakage, that is, the sound may pass through during the meeting. Some air leaks or other ways. Unauthorized personnel can accidentally or deliberately hear a leak in the conference room. Anti-eavesdropping equipment can be installed so that more sound information can be transmitted.
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. So how to effectively prevent important information from being leaked?
Recording blocker is the first security protection product that uses the world's leading acoustic interference technology, from the inside to the outside, from hardware to software, to shield all kinds of recording equipment, and to provide multiple protections for voice messages. This series of products can shield the recording of various recording equipment (and video recording equipment) such as mobile phones, voice recorders, and eavesdroppers, so as to solve the problem of voice information leakage caused by illegal recording.
The recording blocker emits ultrasonic waves with random noise that human ears cannot perceive. When recording digital devices such as mobile phones, these noises are recorded into the digital device together with the sound of normal conversations, making the recorded audio invalid. The audio information in the video also has the same interference effect. Since 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.
