📡 Smart Noise Generator (klikni pre detail)

A top-tier active protection device designed to neutralize all types of listening microphones – stethoscope, parabolic, beam and laser. The generator creates white noise that is inaudible to the human ear but represents an insurmountable acoustic barrier for sensitive microphones. This technology is currently the only reliable way to stop remote microphone attacks in most standard rooms.

The powerful noise generator can feed up to 100 piezoelectric acoustic converters, 2 to 12 low impedance speakers, or any combination thereof. The system can be tailored exactly to the size and nature of the protected area – from a small office to large conference halls.

A unique feature of the system is the built-in microprocessor that continuously analyzes the acoustic background of the room in automatic mode. Based on this analysis, it dynamically adjusts the optimal output noise level, ensuring maximum protection efficiency without unnecessary energy waste.

🔍 Smart Noise Generator – detailed specifications

• Power and capacity
  The generator can power up to 100 piezoelectric transducers or 2-12 speakers. Piezoelectric elements are glued to windows or walls, creating an effective vibration barrier that prevents any microphone from capturing vibrations.
• Automatic regulation (microprocessor)
  The built-in microprocessor analyzes the acoustic background and dynamically adjusts the noise level. Between conversations, it reduces output to zero so as not to disturb the user. At critical moments (phone call, sudden visit), protection is immediately ready.
• HP (High Power) technology
  Special version for demanding applications – protection of concrete walls, car interiors and large spaces. Higher power and lower output voltage enable effective protection even in challenging conditions.
• Invis-Masking (premium add-on)
  Piezoelectric transducers are installed under plaster or behind window frames so as not to disturb the VIP office design. Protection is completely invisible and does not disturb the aesthetics of the space.
• Recommended deployment
  Protect at least the CEO's office, secretariat and meeting room. In urban conditions, a noise barrier is essential because windows are surrounded by many uncontrolled objects.

💡 This system is the cornerstone of active acoustic protection. It combines power, intelligence and discretion. It is the only reliable way to stop remote microphone attacks.

⚡ 230 V power grids Protection (Tempest) (klikni pre detail)

AC circuits pose a double threat. First, acoustic data can leak directly through the electrical wiring (220 V). Second, there is a risk of information signal leakage from office equipment connected to the network. Our solution reliably blocks these channels.

🔍 Power grid protection – detailed specifications

• Active protection
  Network noise generator (0.01 – 1,800 MHz) covers acoustic and data signals. The noise signal exceeds the level of information signals from information retrieval devices. Continuous operation is not recommended.
• Passive protection
  Interference filters (0.01 – 1,000 MHz, 60 dB) block information leakage through power lines. Require quality grounding for effective operation.
• Double threat
  AC circuits pose a double threat – acoustic data can leak through them and there is also a risk of information signal leakage directly from office equipment.

💡 A combination of active and passive protection provides the highest level of electrical network security. We recommend installing both for maximum protection.
