The invention provides a remote fire alarm monitoring management system and a method thereof, and the method mainly comprises the steps: firstly, judging whether a changed region exists in a monitoring video or not, and obtaining a candidate area image; then judging whether the RGB value of the candidate area image falls into a Gaussian mixture model of flame color, if so, analyzing the monitoring video by utilizing time axis wavelet analysis to obtain a first high-frequency wavelet sub-signal and a second high-frequency wavelet sub-signal, and when the difference between the first high-frequency wavelet sub-signal and the second high-frequency wavelet sub-signal exceeds a first threshold value, calculating a variation number according to spatial domain variation, and when the variation number exceeds a second threshold value, determining that the monitoring video has flame components, so that a fire alarm occurs in the space. 本发明提供了一种远程火警监控管理系统及其方法，主要是先判断监视视频中是否具有变动的区域得到一候选区域影像，接着再判断所述候选区域影像的RGB值是否落入火焰颜色的高斯混
