监控体系的好与坏会直接影响到济南保安公司的监控作用，那么怎样才可以购买到好的监控体系呢？从技术上对监控体系进行点评首要包含10个原则：

　　The quality of the monitoring system will directly affect the monitoring role of Jinan Security Company, so how can we buy a good monitoring system? Technical review of the monitoring system includes 10 principles:

　　1、实用性。体系应考虑到济南保安公司所处的环境条件、监督方针、监控方式、保护保养以及投资规划等要素，能满足城市视频监控报警联网体系的正常运转和社会公共安全管理的需求。

　　1, practicality. The system should take into account the environmental conditions, supervision policies, monitoring methods, protection and maintenance, investment planning and other elements of Jinan Security Company, so as to meet the normal operation of the urban video surveillance and alarm network system and the needs of social public safety management.

　　2、牢靠性（Reliability）与安稳性。体系应选用成熟的技术和牢靠的设备，对关键设备有备份或冗余办法。体系软件有保护确有较强的容错及体系恢复功能，以确保体系安稳运转的时间尽可能长，一旦体系发生毛病时能赶快修复或恢复。

　　2. Reliability and stability. The system should select mature technology and reliable equipment, and have backup or redundancy methods for key equipment. The system software has strong fault tolerance and system recovery function to ensure the stable operation of the system for as long as possible, and can be repaired or restored as soon as the system breaks down.

　　3、可扩展性。宜选用分布式体系和模块化结构设计，以习惯体系规划扩展、功用扩充、配套软件晋级的需求。济南保安公司可随时依需要对体系进行扩充或裁剪，表现满意的灵敏性。

　　3, scalability. Distributed system and modular structure should be chosen to meet the needs of Customary System planning, function expansion and promotion of supporting software. Jinan Security Company can expand or tailor the system whenever necessary to show satisfactory sensitivity.

　　4、先进性与继承性。城市视频监控报警联网体系的建造不行能将原有的以模仿为主的体系一概扔掉，适宜的做法是在规划好全数字化体系的前提下尽可能将原有模仿体系纳入其间。理想的体系是在两者之间能做无缝衔接，构成完好的城市视频图像联网监控。

　　4. Advancement and inheritance. The construction of urban video surveillance and alarm network system can not throw away the original imitation-based system. The appropriate way is to incorporate the original imitation system into it as far as possible under the premise of planning a fully digital system. The most ideal system is to seamlessly connect the two, and form a complete network monitoring of urban video and image.

　　5、性能价格比。设计者应合理设置体系功用、正确进行体系配置和设备选型，在关键设备层次优良的前提下，确保体系的全体价格较低，然后让体系具有较高的性价比。体系前端的摄像机选型和后端软件的水平应是关注的要点，前端摄像机的线数若低于460线，后续体系再好也杯水车薪，是不行能确保体系有清晰图像作用的。在某些使用场合还需要有宽动态规划等高档特性。

　　5. Performance-price ratio. Designers should reasonably set up the functions of the system, correctly configure the system and select the type of equipment. On the premise of the excellent level of key equipment, they should ensure that the overall price of the system is low, and then make the system have a higher cost performance ratio. The selection of front-end cameras and the level of back-end software should be the focus of attention. If the number of front-end cameras is less than 460 lines, no matter how good the follow-up system is, it is impossible to ensure that the system has a clear image effect. In some applications, high-end features such as wide dynamic programming are also needed.

　　6、体系晋级和维修的快捷性。因为体系规划较大，体系软件和中心设备应具有主动晋级保护功用；另外，城市监控报警联网体系是由多个复杂的体系组成，包括网络、存储、操作体系、渠道软件、各种前端设备等，所以要求每个子体系均应具有作业日志记录，包含体系各模块和中心设备。

　　6. Rapidity of system promotion and maintenance. Because the system planning is large, the system software and central equipment should have the function of active promotion and protection; in addition, the urban monitoring and alarm network system is composed of many complex systems, including network, storage, operation system, channel software, various front-end equipment, etc., so it is required that each sub-system should have a job log. Record, including system modules and central equipment.

　　7、体系的办理功用及易操作性。考虑到联网体系的规划及复杂性，办理软件渠道应具有较好的体系构架，体系中心办理和事务办理有必要清晰别离，以确保满意不同的使用需求。因为体系中各类办理服务器、存储及转发服务器等数量较多，所以体系的网管功用必须要强大，不然无法进行日常保护；体系所供给的办理和用户界面要清晰、简练、友爱，操控应简便、灵敏、易学易用，便于办理和保护。

　　7. The function and operability of the system. Considering the planning and complexity of the networking system, the management of software channels should have a better system framework. It is necessary to clearly separate the management of the system center from the transaction management to ensure that different needs are satisfied. Because there are many kinds of processing servers, storage and forwarding servers in the system, the network management function of the system must be strong, otherwise it can not be routinely protected; the management and user interface provided by the system should be clear, concise and friendly, and the control should be simple, sensitive, easy to learn and use, easy to handle and protect.

　　8、体系支撑二次开发的功能。一个城市的监控报警联网体系的摄像机数目少也有数百个，多的可达几万个，因而有必要考虑到渠道的可持续发展问题。要达到“视频发明价值”的方针，就要求体系具有二次开发的条件，只有这样才可以确保渠道视频资源的充分利用。

　　8. The system supports the function of secondary development. There are at least hundreds of cameras and tens of thousands of cameras in a city's monitoring and alarm network system, so it is necessary to consider the sustainable development of channels. To achieve the goal of "video inventive value", the system must have the conditions of secondary development. Only in this way can we ensure the full use of channel video resources.

　　9、体系的安全确保程度。体系安全包含多个方面，其间主要是避免不合法用户及设备的接入，所以除对不同用户（包含办理员和用户）要采纳不同程度的验证手段外，还要确保不合法的设备不能接入到体系中去。联网监控体系易受到黑客的进犯，应采纳有用的安全保护办法，避免体系被不合法接入、不合法进犯和病毒感染。此外还需防雷击、过载、断电、电磁搅扰和人为损坏等不安全的要素，以供给全面有用的安全确保办法。

　　9. The degree of security assurance of the system. System security includes many aspects, among which the main purpose is to avoid illegal users and equipment access, so in addition to different users (including operators and users) to adopt different levels of verification means, but also to ensure that illegal equipment can not be accessed to the system. The network monitoring system is most vulnerable to hackers. Useful security measures should be adopted to avoid illegal access, illegal intrusion and virus infection. In addition, it is necessary to prevent lightning strike, overload, power failure, electromagnetic disturbance and man-made damage and other unsafe elements in order to provide comprehensive and useful safety assurance measures.

　　10、兼容性与规范化程度。兼容性是完成很多不同厂商、不同协议的设备间互联的关键。体系应能有用地通讯和共享数据，尽可能完成设备或体系间的兼容和互操作。体系的规范化程度越高、开放性越好，则体系的生命周期越长。操控协议、传输协议、接口协议、视音频编解码、视音频文件格局等均应契合相应国家规范或行业规范的规定。

　　10. Compatibility and standardization. Compatibility is the key to the interconnection of devices with many different manufacturers and protocols. The system should be able to communicate and share data effectively, and achieve compatibility and interoperability between devices or systems as far as possible. The higher the degree of standardization and openness of the system, the longer the life cycle of the system. Operating protocols, transmission protocols, interface protocols, video and audio coding and decoding, video and audio file format should conform to the relevant national or industry specifications.
