Design Inspiration

In the days when there were no recording devices, we only had to worry about our conversations having ears through the walls, and in a safe environment our conversations were known only to heaven and earth, and to you and me.
But with the development of electronic technology, our cell phones have recording function, recording pen is even more compact and portable, the camera also has the double function of shooting and recording, those professional eavesdropping instruments are even more powerful.

Our conversations, our decisions, our ideas are all at great risk of being leaked. Protecting the security of our conversations is the reason why we designed the recording jammer in the first place.

Protect the security of important meeting content

As the threat of espionage continues to grow, securing our face-to-face discussions has become very important. Government agencies, military units and large corporations are acutely aware of this. Our recording jammers prevent eavesdropping devices from collecting the content of our discussions, as well as blocking unauthorized recordings, minimizing the leakage of important information.

Protect your speech in public from leaking out

Chinese people know that people are afraid of being famous and pigs are afraid of being strong. When your status reaches a certain level, there are always unsavory people who will try to find evidence of your mistakes in order to pull you down from your high position. We're not preaching a crisis of confidence, we're just trying to avoid as much trouble as possible. Recordings are often used as evidence, and recording jammers have been developed to keep recording devices from recording conversations, and to protect what you say in public from leaking.

Smart devices may be listening in on you

Whether you want to believe it or not, connected smart devices may be listening to our conversations. Cell phones may be on standby with the microphone always on, and voice-activated assistants may be silently recording our conversations. It is imperative that steps are taken to prevent these violations from occurring.

Portable audio jammer can be freely combined according to the area of the venue to build the safe area you need. Application scenarios: office, restaurant, home, car and any private conversation area you need. Protecting the privacy of your conversation is its mission.
