What brand of recording jammer is easy to use? "The recording jammer is upgraded on the basis of the original equipment. The FPGA-based ultrasonic noise algorithm eliminates the high-frequency noise of the old equipment. It adds the information of the various brands of mobile phones and recording equipment that have been on the market in the past two years. It is aimed at the new recording equipment. And mobile phone recording has a very obvious effect.
The recording jammer is based on the FPGA-based ultrasonic band noise algorithm, which does not produce sound and does not affect health during work; mainstream recording equipment (mobile phones, voice recorders, voice recorders) widely used in the market can achieve the shielding effect; the appearance can It is a polymorphism customized according to user needs, such as telephones, clocks, etc.; it can be disguised as speakers, pen holders, etc. in the living or office environment, and the environment is perfectly integrated to achieve true invisibility.
Advantages of recording jammers: high interference intensity: our self-developed FPGA-based ultrasonic noise algorithm can effectively interfere with digital devices such as mobile phones, voice recorders, etc., can record noises, and completely eliminate the harshness that a few people can hear sound. Long interference distance: The interference distance of the recording jammer to 95% of mobile phones is more than two meters, the interference distance to 60% of mobile phones is more than 5 meters, and the interference distance to mobile phones such as iPhone X and iPhone 8 is 10 meters, which can effectively protect the conversation. content.
The recording jammer has a long interference distance, which eliminates the harsh sound that a few people can hear. There are many devices that can interfere, including Apple mobile phones that are not easy to interfere. The radius interference distance can reach more than 10 meters. The recording jammer is completely silent when it is working. The sound recorded by ultrasonic recording and eavesdropping equipment is completely noisy, and no meaningful information can be extracted. Designed with the appearance of ordinary audio. It is suitable for confidential meeting rooms, public security bureau petition centers, procuratorate reception halls, courts, negotiation rooms, offices and other places for private conversations.
