This compact wireless audio recording blocker, reminiscent of a small camera, is an advanced espionage device. It operates using the FPGA sonar ultrasonic noise algorithm and harnesses multi-frequency superposition air spiral sound wave interference technology. No audio recording devices can evade its reach.
When an individual attempts to utilize a recording device, such as a smartphone, a covert bug placed in a location, or a portable recorder, to capture your voice data, this multi-frequency sound wave audio recording blocker generates a random noise signal that effectively interferes with their recording efforts. Consequently, the recording device captures only noise, unable to differentiate any significant vocal information.
The P-US-BH is conveniently sized and feels natural in your hand. It can easily fit into your clothing pocket, making it a hassle-free accessory to carry.
Employing this device feels akin to possessing an invisible barrier. Seeking assurance that your confidential information remains secure? This blocker represents an optimal solution!
