This suitcase type 9-terminal voice jamming device is based on sound wave interference technology. It blocks the pickup function of recording equipment by emitting frequencies that are imperceptible to the human ear (such as ultrasound and white noise).
Even after complex post-processing algorithms, it is difficult to restore the original conversation submerged in random noise, thus completely preventing information leakage.
Because its interference sound waves are beyond the hearing range of the human ear, the device has little impact on the surrounding environment during operation. Participants will not notice any noise interference, and the conversation process remains natural and smooth. At the same time, the device can intelligently respond to different types of eavesdropping methods and provide comprehensive protection.
The outstanding feature of the ultrasonic anti-voice jammers is its efficient multi-sound unit layout. The closely arranged sound units ensure effective shielding within a range of 90 to 120 degrees.
P-US-N9 supports angle adjustment. Users can flexibly adjust the angle according to the specific location of the target device to ensure the accuracy of the shielding effect and the breadth of coverage.
The device is equipped with stable support feet at the four corners, which can ensure that it is stable and does not slide when placed on or under the table, and will not move even during long-term use.
If you think P-US-N9 is not concealed enough, I suggest you choose our anti-recording jammer P-US-00-1, which looks like a mobile power bank and will not be easily noticed when used in various environments.
