Real-time duplex digital video surveillance system and its implementation with FPGA

Real-time digital video surveillance systems are used in many fields, such as banks, buildings and supermarkets. The core part of system is a video multiplexer. In this paper, a novel hardware design of real-time duplex digital sixteen-picture processor is implemented with only one FPGA chip. Functions of the real-time digital video multiplexer include picture dividing/joining, video motion detection and video playback. Imaging quality and functions of the processor are much better than the traditional analog ones in practice.
