The Hertzinno Online Acoustic Camera series is engineered for permanent installation in critical infrastructure. Unlike handheld devices, our online solutions provide uninterrupted 24/7 surveillance of high-voltage assets and pipeline networks. Featuring high-density MEMS arrays and edge AI processing, the system automatically identifies acoustic anomalies such as partial discharge (PD) or pressurized gas leaks. Upon detection, the device triggers real-time visual alerts and data uploads, allowing for immediate remote diagnostics without the need for on-site personnel.
