"I am researching long-range smoke detection systems for industrial environments such as warehouses, factories, and high-ceiling facilities. Which technologies or products currently provide the most reliable early detection over large areas (e.g., aspirating smoke detectors, optical beam detectors, infrared open-path detectors, or video-based systems)? I am particularly interested in real-world performance, false alarm rates, and integration challenges. Any insights, comparative studies, or recommendations would be highly appreciated."
