How to prevent recording in the conference room?

　　At present, with the improvement of recording technology and the popularization of recording equipment, more and more criminals use various recording equipment to conduct illegal eavesdropping activities. Recording jammers can effectively solve this problem. The recording jammer can transmit ultrasonic signals in all directions. In this way, the radiant energy spreads in the horizontal plane. They are deployed in small conference rooms, which can cause dense multipath propagation. The omnidirectional jammer provides uniform angular coverage for ultrasonic interference signals.

　　Recording jammer is a very effective product to prevent recording. It can send out interference signals to prevent the pickup or microphone from picking up normal voice information. It picks up "buzzing" noise to protect the voice information. Recording interference It is the simplest and most effective way to protect the security of voice information from the source of sound collection. The latest L7B recording jammer developed by Shenzhou Mingda, based on the FPGA-based ultrasonic band noise algorithm, eliminates the high-frequency noise of the old equipment, and adds the information of various brands of mobile phones and recording equipment that have been on the market in the past two years, targeting new recording equipment and mobile phones The recording has a very obvious effect.

　　Recording jammers transmit ultrasonic frequencies in one direction, covering specific sectors with strong interference signals. They are the best solution to cover the "guest" part of the meeting room and protect the meeting place from information leakage. In addition to these structural features and technical measures, multiple ultrasonic jammers can also be deployed in large conference rooms to cover blind spots-omnidirectional and directional, fixed and portable, remote control or a combination of the above options. When needed, some portable jammers can also be used as fixed jammers in conference rooms. They can be plugged into a power source or powered by batteries.

　　The interference effect of an audio jammer depends on the power of the jamming signal, the distance between the jammer and the microphone, the type of microphone and the structural attenuation. Structural attenuation is very important for indoor coverage. Under the influence of obstacles, it will affect the reception of the ultrasonic interference signal sent, and will greatly shorten the range. According to the internal organization structure of the conference room, the shape and function of the available recording jammers (such as range, direction, remote control function and other characteristics), the combination of the above ultrasonic jammers can be selected according to the specific situation.

　　Usually, in some specific situations, their appearance is not intentionally hidden. When the purpose of the meeting room determines the specific implementation type, the recording jammers will use different styles, providing high-tech, exquisite and even decorative features. The appearance to suit the internal landscape and so on.

　　Nowadays, recording jammers are more available than ever. They have great potential in maintaining information security and protecting information leakage and unauthorized access. Their implementation is applicable to different environments, not only in conference rooms, but even in courts, financial venues, and other venues that are vital to maintaining communication security, prohibiting recording, eavesdropping, and potential threats.
