Abstract: It is always a challenging task to share video resources between isomerous video surveillance systems. A hierarchical system for isomerous video surveillance integration based on the technique of virtual device interface (VDI) is proposed, which is composed of sever kernel level, virtual device drive level, protocol transformation level and physical equipment interface level. By incorporating the VDI technique into our system, the proposed system is compatible with various different video equipments and capable of transformation of different communication protocols as well as the video coding algorithm. Our experimentations show that our system can integrate video devices produced by different manufacturers, thus video sources can be shared with each other effectively, which also validates the expansibility and compatibility of the proposed system.
