🔥 1. Introduction Thermal cameras are advanced imaging devices that detect heat instead of visible light. By measuring infrared radiation emitted from objects, they create a temperature‑based image that reveals hotspots, temperature anomalies, and early signs of fire risk. Unlike traditional detectors, thermal cameras work in complete darkness, through dust or haze, and provide continuous real‑time
