A Design of Low-Cost Low-Bandwidth Mobile Video Surveillance System Based on DM6446

Facing, challenges of bandwidth limitation, high realtime and high computing, we propose a novel design of mobile digital video surveillance system (MDVS) in virtue of hardware-software co-design approach and TI DaVinci technology. GPRS is adopted as communication network without infrastructure installation. The hardware based on dual-core DM6446 and software design based on H.264 tackle bandwidth and real-time challenges excellently. With other peripherals, the design implements a wide range of MDVS functionalities such as motion detection, PTZ control, etc. The merits of low cost, low bandwidth, high flexibility, ease installation, convenient operation make the application can be applied in a variety of scenarios.
