In this paper, we introduce a real-time, AI-powered system for detecting fire and smoke through security cameras, specifically designed to drastically reduce false alarms. Traditional smoke detectors are often slow and only cover small areas, while standard camera-based systems easily get tricked by bright lights or reflections. To solve this, our system combines two models: YOLOv11 to quickly spot potential danger zones, and EfficientNet-B4 to carefully classify those areas as fire, smoke, or just normal lighting. The system evaluates both the specific hot spots and the overall scene to make a confident decision, then double-checks its results across multiple video frames to ignore quick camera glitches. We trained our models on about 35,000 images so they can reliably handle real-world situations. In our tests, the system hit 92.8 percent accuracy and slashed false alarms from 12.8 percent down to just 2.4 percent. Plus, it runs smoothly in real time at 20 to 25 frames per second. Overall, it is a practical, ready-to-use solution built to keep people safe and scale up as needed.
