OVERVIEW
Description
High-Sensitivity. Low-Power. Mission-Ready.
The QuakeLogic SIS-1 Infrasound Sensor is a compact, high-precision instrument designed for the detection of ultra-low-frequency acoustic waves (0.1 Hz – 50 Hz). Built for defense, military, and security operations, SIS-1 enables reliable identification and tracking of unmanned aerial vehicles (UAVs), explosions, and other acoustic anomalies—across borders, remote terrains, or critical infrastructure.
Its rugged design, low-power consumption, and exceptional sensitivity make SIS-1 ideal for tactical field deployment, permanent installations, and scientific monitoring in the most demanding environments.
Key Technical Features
- Wide Frequency Range: 0.1 Hz – 50 Hz (−3 dB bandwidth) for broad-spectrum infrasound detection
- High Sensitivity: 2.5 mV/Pa – 3.5 mV/Pa for capturing faint acoustic signatures
- Ultra-Low Noise Performance: Self-noise below the Low Noise Model (LNM) for sub-Hz precision
