"Residential surveillance" as a public security organ program is an important link in fighting crime may inevitably affected. During the period of residential surveillance without the approval of the executive organ shall meet with others or communication,in the absence of the Internet age, enforcement agencies need to take it only limited in a certain area, as the case restrict or prohibit the dial telephone and other measures,but with the rapid development of Internet and the popularization, the Internet communication as a kind of new way of communication inevitably become a new topic in the residential surveillance.In this paper, the related network specific group behavior, has carried on the analysis of the monitoring and early warning, on this basis, completed the network specific group behavior analysis and early warning system of user requirement analysis,analysis of the construction of key personnel threat level evaluation index system of the content and method, to study the method to determine the weights of the weight,key personnel risk quantification method, risk rating method and so on, analyzed the business process, the system functional requirements and non-functional requirements,and a use case analysis was carried out. On the basis of demand analysis, has carried on the system's overall design and detailed design, detailed describes the personnel management, the index weight calculation and the evaluation results calculation module and other modules. Paper describes the system testing, system deployment and system interface display.The development and application of this system timely and properly, can help the public security to residential surveillance enforcement agencies to solve practical security issues, and played a huge role in society as the foundation system. This system in the process of application implementation while there is a certain amount of shortage, it will be continue to perfect and improve the system, and to further improve the public security organ's ability to adapt to the rapid development of the Internet to ensure the justice of law.
