In order to prevent the content of the company's internal meetings and personal conversations from being overheard and secretly recorded, and to protect our conversations from being used with ulterior motives, Shenzhou Mingda has re-upgraded on the basis of the original equipment, and the FPGA-based ultrasonic noise algorithm has been developed and upgraded. The MDPB-L7B recording jammer 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. It has a very obvious effect on the new recording equipment and mobile phone recording.
When criminals use recording equipment (such as mobile phones, voice recorders, tape recorders, etc.) to record you, the recording jammer will generate random noise signals, which can produce suppressive interference to the voice signal, so that the recording equipment picks up only Noisy information, and voice information cannot be distinguished, so as to ensure the safety of voice information. Widely used in: leadership offices, confidential meeting rooms, military war rooms, business negotiation rooms and other places that prevent recording.
Compared with other products on the market, the recording jammer has higher interference power, the noise signal picked up by the recording device is stronger, and the shielding effect is stronger. Compared with other products, its shielding distance is longer. The interference distance of recording jammers to most mobile phones on the market is more than two meters. For some recording devices, the shielding distance of mobile phone voice recorders can reach 5 meters, which covers a wider range of equipment. At present, mainstream mobile phone voice recorders have a coverage rate of over 85% of recording jammers, which is much higher than similar products on the market.
