1. Current situation analysis
In recent years, various campus governance incidents have occurred frequently. In order to effectively protect the personal safety of teenagers and children, prevent the occurrence of cases of foreign infringements, and maintain normal school teaching and living order, the Ministry of Public Security, the Ministry of Education, and the Central Comprehensive Management Office Other departments jointly dispatched and formulated a series of safety precautions, and the construction of "safe campus" and "digital campus" in various places was carried out one after another.
With the construction of more and more campus monitoring systems, how to ensure the effective use of these systems, how the upper management department can grasp the operation of each campus monitoring system, ensure the normal operation of the monitoring system for a long time, and assist when an alarm event occurs Functions, these need the video surveillance operating state detection system to achieve.
The video surveillance operation status detection system is to change the traditional surveillance system operation and maintenance process, due to human subjective judgments, technical bottlenecks, lack of experience accumulation and other factors, the maintenance is difficult and the system has hidden dangers. From the video surveillance operation and maintenance business Starting from the actual needs of the company, apply advanced intelligent technology to operation and maintenance management and services, optimize the complicated and time-consuming operation and maintenance work, meet the needs of the continuous development of the video surveillance operation and maintenance field, and truly realize the intelligent operation and maintenance of video surveillance And management, to help users control the operation of the equipment in real time, and conveniently maintain the video surveillance system.
At present, there are often reports that surveillance becomes "eye-opening blind" in the newspapers, and it is extremely impractical to inspect the huge and rapidly growing video surveillance sites with limited manpower, which makes video surveillance equipment produce the following in terms of operation and maintenance guarantee services Various problems: The troubleshooting delay is serious, the incident cannot be responded to in time, and the limited manpower is difficult to support; the equipment model standards are diverse, the maintenance mode is inefficient, and the maintenance service is quite difficult.
2. Development trend
The operation and maintenance of the video surveillance system is entirely dependent on manual detection and processing. The monitoring is difficult, the fault processing is not timely, and the operation and maintenance workload is huge, resulting in the continuous increase of the cost of operation and maintenance, and the use of the video surveillance system is greatly reduced. Therefore, improving the informatization level of video surveillance system operation and maintenance work and building an informatized video surveillance operation and maintenance management system will surely become the development trend of the video surveillance industry.
Video surveillance system online monitoring and operation and maintenance system, as an innovative product in the security field, is a typical application of video analysis technology and various new IT technologies in the operation and maintenance of video surveillance systems. The system integrates status monitoring, fault alarm, fault analysis, and operation and maintenance management. It can monitor and query the operating status of equipment related to various video surveillance systems, such as cameras, video and audio codec equipment, and business servers. Once the operation and maintenance system finds that the operation status of the video surveillance system equipment is abnormal, it will immediately send a fault alarm to the operation and maintenance management center.
After the operation and maintenance system management center receives the equipment failure alarm, it automatically conducts failure analysis and initially analyzes what caused the failure. At the same time, through a unified operation and maintenance service operation platform, the operation and maintenance system automatically finds faults, manual warranty faults, daily maintenance and other work to carry out unified and standardized management, to track the fault handling throughout the process, and complete advanced and reasonable fault repairs. Task dispatching electronic flow system to respond faster and complete fault repair tasks.
The online monitoring and operation and maintenance system of the video surveillance system can ensure the normal operation of the video surveillance system in a comprehensive, systematic, standardized and timely manner, changing the current situation of difficult maintenance of the video surveillance system and low effective utilization rate.
Three, system deployment
