You can use a recording blocker to prevent recording during important meetings!

The most effective means to prevent recording is to generate random noise signals through the recording masker, which can suppress the voice signal, so that the recording equipment picks up only noise information, but cannot distinguish the voice information and cannot restore it from the recorded signal. The original information is output to ensure the security of voice information. The recording blocker adopts security encryption processing, and effectively prevents post-restoration by mixing high and low frequency audio sources.

Jammer-mart has focused on information security for 14 years. The newly developed L7B recording jammer has been upgraded on the basis of the original equipment. The FPGA-based ultrasonic noise algorithm eliminates the high frequency noise of the old equipment. It has joined the brands that have been on the market in the past two years. The information of mobile phones and recording devices has a very obvious effect on new recording devices and mobile phone recording. 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.

The recording blocker is completely silent when 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. Confidential meeting room, public security bureau petition center, prosecutor’s office reception hall, courtroom, negotiation room, office and other places for private conversation.

Working principle: The recording jammer emits ultrasonic waves with random noise that cannot be perceived by human ears. When digital devices such as mobile phones are recording, these noises are recorded into the digital device together with the sound of normal conversation, 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.

As a new product, recording jammers have received more and more attention and support from people. From the previous government agencies (mainly the public security system and service-oriented windows) to the current enterprises, the needs of enterprises have gradually increased. An important reminder for us. It shows that business people are gradually attaching importance to the safety of voice information and their awareness of self-protection has increased. Imagine if in a conversation scene, if any participant turns on the recording device, or connects the call and keeps it in the call state, the remote personnel can There is no security to hear the content of the conversation at will. In this case, the recording blocker can play a good role in protecting the security of audio information.
