Argus-D is an AI-based disaster detection CCTV that integrates advanced artificial intelligence and multimodal technology into the core of conventional security cameras. In an era of increasing large-scale disasters caused by climate change, Argus-D provides a critical solution by rapidly detecting statistically prevalent threats such as forest fires, building collapses, and earthquakes. To overcome the limitations of conventional server-based AI solutions, Argus-D incorporates multimodal sensors and cutting-edge Physical AI. This technological fusion delivers superior performance, including over 99% accuracy in fire detection. For seismic events, it goes beyond simple detection and is capable of analyzing P and S-waves to determine the direction and distance to the epicenter. With certified UL and FCC compliance, Argus-D combines visual intelligence, sensor fusion, and smart IoT connectivity to provide proactive disaster protection for people, property, and next-generation safety infrastructure.
