Anti-recording shielding jammer to prevent being recorded" The anti-recording jammer can realize recording shielding in a concealed manner under silent conditions. When criminals use recording equipment (such as mobile phones, voice recorders, eavesdroppers, etc.) to record you At the time, the recording muting device will produce interference noise signals, which can produce suppressive interference to the voice signal, so that the recording equipment picks up only noise information, but cannot distinguish the voice information, and cannot restore the original information from the recorded signal. So as to ensure the security of voice information.
Recording jammers interfere with various recording equipment such as mobile phones, voice recorders, and eavesdroppers. They have the characteristics of good shielding effect, high security, multiple application scenarios, customizable shapes, and no electromagnetic radiation. Compared with related products at home and abroad, it has great advantages in terms of shielding effect, safety, practicability and concealment. Applicable occasions: It can be used in offices, conference rooms, inquiry rooms, courts, mobile offices, and can effectively solve individuals, enterprises, government agencies (such as the public security system, the army, the disciplinary committee...), etc., and can also be carried out according to customer needs custom made.
Recording jammer When a digital device such as a mobile phone is recording, it will emit ultrasonic waves with random noise that the human ear cannot perceive. These noises and the sound of normal conversation are recorded into the digital device, making the recorded audio invalid. The audio information in the captured video 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. The sound waves emitted by the anti-recorder can only be received by digital products such as mobile phones and voice recorders but cannot be heard by humans. 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.
