Everyone will find that the development of video surveillance systems has become the mainstream development trend of the security industry. In general, the technical requirements are high, the investment is large, the users are involved, and there are many links, from image collection, transmission, storage, management, sharing, etc. Many links, which requires the quality of our team's video surveillance system to be a standard, therefore, follow the 10 major guidelines for good or bad video surveillance system at a glance.
One: the security of the system. Unsafe factors such as lightning strikes, overloads, power outages, electromagnetic interference and vandalism are required to provide comprehensive and effective safeguards. In addition, the networked monitoring system is the most vulnerable to hackers. The system security is mainly to prevent the access of illegal users and devices. To ensure different levels of authentication, it is also necessary to ensure that illegal devices cannot be connected to the system. Effective security measures should be taken to prevent unauthorized access, illegal attacks and virus infections.
Second: the degree of standardization and compatibility of the system. The higher the degree of standardization of the system and the better the openness, the longer the life cycle of the system. Control protocols, transmission protocols, interface protocols, video and audio codecs, video and audio file formats, etc. shall comply with the corresponding national standards or industry standards. Compatibility is that real systems should be able to communicate and share data efficiently, and to achieve compatibility and interoperability between devices or systems as much as possible.
Three: system cost performance. The solution design company should correctly carry out system configuration and equipment selection, reasonably set the system function, and make the overall system price lower under the premise of excellent equipment grade, so that the investment is low and the performance is high. The focus of the system is on the front-end camera selection and back-end software technology. If the front-end camera has less than 480 TV lines, the back-end monitoring system technology cannot guarantee the overall system has clear image effects. In some special occasions, advanced monitoring equipment and technology suitable for special environments are also required.
Four: The convenience of the system's monitoring and management functions. A management software platform that wants such a large system has a good system architecture, and its system core management and business management must be clearly defined. Because the number of management servers, storage and forwarding servers in the system is large, the network management function of the system must be strong. Otherwise, routine maintenance cannot be performed. The management and user interface provided by the system should be clear and concise, and the control should be simple and flexible. Easy to learn and use, easy to manage and maintain.
Five: the practicality of the monitoring system. Before designing a complete networked video surveillance system, first consider the local environmental conditions, monitoring scope and object, monitoring mode, maintenance and maintenance, system investment scale and other factors, to meet the needs of social public safety management and the city's networked video surveillance system The normal operation.
Six: The reliability and stability of the system. This set of monitoring system should choose high-quality monitoring equipment and adopt high-tech technology to ensure the stable and smooth operation life of the system as long as possible. The system software should have strong recovery ability and maintenance support ability to prevent problems before they occur.
Seven: The system has technical functions developed again. We know that the number of cameras in a city's networked surveillance system is very large, ranging from hundreds to tens of thousands, so the sustainable development of the platform must be considered. The system is required to have the ability of secondary research and development technology, and only in this way can the platform video resources be fully reused.
Eight: rationality and advancement. It is to prepare the original simulation system as much as possible under the premise of planning a fully digital system. It is the ideal system to seamlessly connect the two to form a complete urban network video surveillance image.
Nine: Easy to operate system upgrades and repairs. Because the urban networked video surveillance system is composed of multiple complex systems, including network, operating system, platform software, storage, various front-end equipment, etc., the system scale is large, and the system software and core equipment should adopt automatic upgrade and maintenance functions; Therefore, each subsystem is required to include all modules and core devices of the system, and should have work log records and backups.
Ten: System scalability. It is recommended to use modular structure design and distributed system. The system should have the functions of function expansion, supporting software upgrade and scale expansion. The monitoring manager can expand or tailor the system at any time to fully reflect the flexibility of the system.
Through the above ten points of understanding, we can clearly understand the performance of the video surveillance system, which is an efficiency improvement measure for our production.
