This paper presents a manageable framework for multiple event-detection technologies to cooperate with each other. It makes newly defined or redirected events safer and more reliable. In recent years, with people's pressing needs for security, there are increasing demands of surveillance structures that are capable of monitoring multiple independent events simultaneously. Thus we propose a framework to associate some detection technologies to an event definition, and then we can save the building of the overlaid monitoring, alarming and detection components are saved. At last, we have an example to show how this framework can be beneficial for us.
