The iProtect DNG-2300 3-Channel White Noise Generator Kit 4 is a compact, professional-grade counter-surveillance system engineered to protect private conversations from eavesdropping, acoustic leakage, and electronic listening devices.
When paired with TD2300 Transducers and SP2300 Acoustic Speakers, this advanced generator produces a broad-spectrum white noise signal that neutralizes all types of surveillance attempts. It injects vibration-based interference into walls, windows, and structural surfaces while simultaneously emitting audible masking noise into the air—effectively blocking microphones, stethoscopes, and laser listening systems from capturing intelligible speech.
Ideal for executive offices, conference rooms, law firms, military and government facilities, and high-security environments, the DNG2300-4 provides professional acoustic protection in a compact and portable kit.
