Still worried about your conversations being recorded by malicious individuals? Our newly launched P-AJ40 audio bugs jamming device blends into the background and works unnoticed.
The palm-sized speech blocker can defend against a variety of recording devices, including radio frequency transmitters (wireless bugs), wired microphones, contact microphones, and directional microphones. It also helps defend against more advanced threats such as microwave or laser-based eavesdropping systems, which capture sound by analyzing vibrations reflected off glass surfaces like windows.
What makes it practical is its straightforward power setup. The audio jammer runs on a single rechargeable 9V lithium-ion battery ( Not to be used with alkaline battery). A full charge delivers around 3–6 hours of operating time, while the charging cycle takes less than 2 hours. The reason is simple: it’s designed for repeated daily use, not long waiting times. Whether it’s a meeting room, consultation space, or private office, it stays ready when needed.
Coverage extends up to 200 square feet, which is enough for most small to medium indoor rooms. ( Here’s a small suggestion: If you need to use it in a larger room, it’s recommended to add one P-AJ40 unit for every additional 200 square feet of space.)
And there are small details that make a difference. The structured perforated metal panel isn’t just for appearance—it improves heat dissipation during continuous operation, helping the device stay stable over time. Once powered on, and the indicator light immediately turns on ( Select the protection level according to different situations using the buttons). That simple signal confirms everything is working as expected.
