Technology: NAS intelligent monitoring in the security industry's strengths
Abroad, NAS devices have become the preferred network data storage devices, and an annual increase rate of 66.5%. NAS Product Has been widely applied to educational research, ISP / ASP, IDC, Web / E-mail server cluster, Financial / Insurance, telecommunications, CAD, medical system, printing, Internet audio and video on demand VOD and many other fields. In China, there are more and more Enterprise Recognizing that data security will become the lifeblood of the industry. From the rapid development of China in recent years can be predicted, NAS storage pattern in China will be faster than the foreign penetration to the industry.
NAS, the English full name NetworkAttachedStorage, can be translated into network-attached storage, is a private data storage server. Its data-center storage and server will be completely separate, centralized management of data, thus freeing up bandwidth, improve performance, reduce total cost of ownership, investment protection. The cost is far lower than those of server storage, and efficiency is much higher than the latter. NAS to meet those who wish to reduce storage costs but can not afford high prices SAN needs of SMEs, with very good cost performance.
Exactly which industries can use to NAS equipment? First of all, look at the unit's core business is built on some kind of information systems, security requirements of data is high; Second, see whether the information system has been or will be there will be a flood of data needs to be saved, and require a higher level of data management; Finally, you can judge for themselves whether the heterogeneous network platform, or it may not be used. If you have a question above the answer is yes, then it is necessary to consider the use of NAS devices focus.
With the computer network Technology The rapid development of video monitoring system is now in order to DVR digital hard disk video recorder digital video surveillance system on behalf of the full to the server to NVS, Network Video Server, IPCamera network camera.
And the recent rise of the NVR Network Video Recorder Network video represented Monitoring System Transition phase, during this transitional phase, the vast majority of applications in digital and network hybrid system, NetworkDVR Network Digital Video Recorder is one representative of the hard disk.
Compared to digital video surveillance, the IP-protocol-based network video monitoring system can build a larger, more complex, more flexible, more scalable application system, the core part is a set of broad compatible and highly integrated management of intelligent video surveillance software, monitoring systems and computer networks / information management system connected to two independent systems to integrate, in order to achieve a true triple-play (data, voice and video images).
A complete set of intelligent video surveillance management software suitable for medium and large IP network video surveillance Environment Not limited to large ones under digital video imaging equipment, access control systems, professional alarm host, environmental monitoring, centralized monitoring and management, and geographic information system with GIS and other computer information management system tightly integrated. As the network video monitoring is a web-based audio and video streaming, audio and video streaming in a large number of case management of video surveillance will be a significant impact on server performance, more data, video monitoring and management server I / O operation scheduling and cache management becomes more complex, frequent visits to the storage devices need to take up a lot of resources to the detriment of its processing power.
If the video surveillance storage management server application is based on the DAS that the local hard disk or external disk array of programs, usually these problems:
Store difficult to extend, can not line expansion, installation and maintenance are complex;
Data processing and data storage capabilities can not separate the video surveillance management server on the local hard disk or external disk array storage devices such as the frequency of visits would take a lot of system resources, reducing the processing stream data;
Storage utilization is low, data sharing difficulties;
Prone to single points of failure, when the local hard disk or external disk array logical or physical failure occurs, all the stored data may be lost, leading to disruptions.
Contrast, NAS (network access storage) is more suitable for a new generation of network video surveillance systems. Network Video Monitoring System for Distributed Networked Storage, at any time according to need expansion, storage devices can be distributed anywhere in the network, the flexibility to develop storage backup strategy.
