To reduce loss of life and property fire, an

early warning is an imperative. A fire detection system based on

light detection and analysis is proposed in the paper. This system

uses HSV and YCbCr color models with given conditions to

separate orange, yellow, and high brightness light from

background and ambient light. Fire growth is analysed and

calculated based on frame differences. The overall accuracy from

the experiments has been greater than 90 .-To reduce loss of life and property　fire, an
