| Video surveillance system is widely exists in the road, enterprises,families, and security has become the focus of the construction ofenterprise unit, alarm function in the monitoring is more important. Through the investigation on the part of the monitoring system and alarm functionsfound early, video surveillance market popular there are two technical routes: one is the traditional video monitoring system based on analog signals, is based on the analog camera. Analog camera behind need even many lines, respectively, the transmission of video, audio signal. In thedigital management platform, analog signal need first to be transformed intodigital signal storage, archiving, query, the query to access, and often need to be reduced into analog signals. Facing the real-time query, cross sectoral real-time information sharing complex requirements, analog video monitoring data processing efficiency. It completely unmasked; another is adigital video monitoring system based on IP. IP digital video monitoring system based on IP network camera. The deployment is simple, the network camera can be in the existing enterprise network plug and play. With IP video surveillance, as long as the plug on the line in the Ethernet port, you can hand over by the background to deal with. Convenient and flexible, plug and play, can easily realize the remote access and multiple access.This thesis focuses on the system design and implementation of the Jinhua Municipal Public Security Bureau intelligent IP video alarm, the systemsoftware development platform based on VS2010, the publication databasestorage Postgre SQL, with IIS6.0, the main protocol for SIP, the load balancing of the database by the cluster technology. Intelligent IP video alarm system is mainly used SIP protocol as the software communication protocol, mainly around the alarm, video surveillance, video storage and IPcommunication as the system core requirements development, because the system including hardware, software technology, the main use of the modular technology, this paper simplifies the hardware facilities, and the realization process the software design mainly prominent IP intelligent alarm. The user can demand according to the service and function ofdifferent, choose a variety of application software system in a series of basic services, achieve the complete service modular intelligent alarm system. The non-standard video alarm system is the goal ofdigital video server, digital video recorder and an alarm and other hardware devicesconnected to the alarm security system in accordance with the standard,and can control and management of the non standard system, through the system to achieve the conversion equipment.IP video monitoring alarm system consists of hardware interface, software service management, data storage capacity of four parts and hardware media access, in this paper, the main research of system software and service management and data storage capacity, the use of hardwarehardware transform coder, combined with basic needs of video users, at present based on the Jinhua City Public Security Bureau intelligent IP videoalarm system main function is the live broadcast, video playback and download, alarm feedback, equipment management, user management and log management. Monitoring equipment alarm management system, the monitoring center according to send information back equipment,module for different information processing through the alarm processing,get different alarm types, system alarm of unidentified objects, intrusion alarm device alarm, high and low temperature alarm line equipment andvideo lost alarm, ideal alarm information should include the name of thefault, fault type, fault location, time of occurrence, causes and other information. |
