The AI multispectral fire warning analyzer integrates multispectral physical sensing and AI intelligent algorithm models. It enables 24/7 AI detection of ultraviolet, infrared, and visible light, and works with a three-level networked warning system to monitor temperature surges, high temperature, flames, electric sparks, and combined smoke-and-fire alarms. This allows potential fire hazards to be detected and warned of at the earliest possible stage, achieving true proactive fire prevention.
