This pocket-sized wireless audio recording jammer, which is similar to a small camera, is a real high-tech spy tool. It is based on the FPGA sonar ultrasonic noise algorithm and uses multi-frequency superposition air spiral sound wave interference technology. All recording devices have nowhere to hide in front of it.
When someone attempts to use a recording device (such as a mobile phone, a bug hidden in the room, a portable recorder, etc.) to steal your voice information, this multi-frequency sound wave audio recording jammer will emit a random noise signal to easily disrupt their recording. As a result, the recording device can only capture noise and cannot distinguish any valuable voice information.
P-US-BH is small in size and does not look awkward in your hand. It can also be put into your clothing pocket, so you will not feel that carrying it with you is a burden.
Using it is like having an invisible diaphragm. Want to ensure that your secrets are not stolen? This jammer is definitely your best choice!
