Geospatial video surveillance network (GVSN) is an effective remote sensing approach for urban security and emergency applications. In this paper, the GVSN system could be separated into four basic functional parts that include change detection, object recognition, target tracking and target positioning. Each part has its special utility to solve the security and emergency problems. When the functions applied in urban security and emergency, based on the illustration and analysis of them, the paper emphasizes the importance of the geoinformation to the networks, because it enlarges the surveillance area and enhances the functions of the video networks. And according to the explanation of different security and emergency applications, it also clarifies that the extraction and operation of the target characteristics are the basics of processing algorithms.
