HZ-DA-200 Acoustic Defender is a buried acoustic and vibration monitoring system for unattended area protection. It detects personnel movement, vehicle activity and illegal excavation by analyzing ground vibration and acoustic signals with edge AI algorithms, then reports events through a self-organizing LoRa wireless network.
HZ-DA-200 Acoustic Defender is HERTZINNO’s buried acoustic and vibration intrusion detection system for pipelines, remote sites, perimeter protection and unattended security areas. The system combines MEMS acoustic sensing, coil vibration sensing, AI detection algorithms and LoRa wireless communication to identify intrusion behaviors such as walking, vehicle movement and illegal excavation.
Unlike visible cameras or radar systems, HZ-DA-200 can be buried in the ground to create a covert “invisible line of defense”. It supports 360° full-direction detection, self-organizing wireless networking, long-distance node communication and low-power operation for long-term field deployment. With IP68 protection, 12-month battery life, over 95% detection probability and less than 0.1% false alarm probability, HZ-DA-200 is suitable for outdoor perimeter security, pipeline corridor protection, oil and gas facilities, border control, storage areas and remote unmanned sites.
