The “safe Dehong” HD video surveillance system construction project covers three counties and three counties in Dehong. The number of front-end camera sites is 3,000. At the same time, the design and construction of the command centers of five counties and 65 police stations have been completed. The HD video surveillance application system of the “state-county-police station” three-level architecture upgrades the construction of Safe City in Dehong from standard definition monitoring to HD monitoring. In the State Public Security Bureau Command Center, a comprehensive analysis and practical application platform based on vehicle and personnel traffic data was built to provide a powerful practical analysis and application method for police officers. Since the project was completed and put into use, it has assisted the public security organs of various counties and cities to crack out a number of major cases, greatly improving the efficiency of the case of Dehong public security, and the public security awareness has improved significantly.
