Figure 1 also provides a functional module frame diagram of high-definition IP network cameras that can be used to assist in the analysis of video code streams by connecting a low-cost DSP processor, which is logically complex but not demanding in performance. Using the Avalon and SOPCBuilder system integration tools defined by Altera, the outer automatic integration can greatly improve design efficiency. The need for video surveillance is also fueled by
