Abstract
(EN)
A security monitoring system and an alarm triggering method thereof, wherein the method comprises steps: a first processor obtaining a first signal indicating that an infrared sensor is triggered; according to the first signal, guiding a first camera lens to capture a first image; obtaining a first background image that is stored; comparing the first image with the first background image to discover a difference; and if the difference meets a predefined condition, triggering a first alarm operation. A method enabling infrared sensor detection and image difference detection to function together is used; therefore, a possibility that a false alarm occurs due to high environment temperature can be reduced.

La présente invention concerne un système de surveillance de sécurité et un procédé de déclenchement d'alarme associé, le procédé comprenant les étapes suivantes : un premier processeur obtient un premier signal indiquant qu'un capteur infrarouge est déclenché; en fonction du premier signal, guider un premier objectif d'appareil photo pour capturer une première image; obtenir une première image d'arrière-plan qui est stockée; comparer la première image à la première image d'arrière-plan pour découvrir une différence; et si la différence remplit une condition prédéfinie, déclencher une première opération d'alarme. Le procédé selon l'invention combine une détection par capteur infrarouge et une détection de différence d'image; par conséquent, la possibilité de déclenchement d'une fausse alarme en raison de la haute température environnante est réduite.

安防监控系统及其报警触发方法,其中方法的步骤包括:第一处理器获取表示红外传感器被触发的第一信号;根据第一信号控制第一镜头拍摄第一图像;获取存储的第一背景图像;对比第一图像与第一背景图像的差异;若差异满足预设条件则触发第一报警操作。由于釆用了红外传感器检测与图像差异检测共同作用的方式,能够降低由于环境温度较高导致的误报的概率。
