Surveillance systems have become widely-used equipment for security. Most of them are PC-based but the cost of a PC would discourage a customer to purchase them. Hence, it would be reasonable to develop a cost-effective embedded system for surveillance video recording. Though H.264 can provide higher image quality and compression rate than the widely-accepted Motion JPEG (MJPEG), it requires more computing processing power. In this paper, the authors present an embedded Digital Video Recorder (DVR) designed to reduce the cost and increase video quality. The system is built on Linux. USB is used as a storage medium for video and audio.
