Massive storage of monitoring data faces challenges
With promotion of Xueliang project and construction of a safe city, coupled with increase in people's safety awareness, number of monitoring equipment has increased dramatically, whether in civilian market or in public places. It is expected that by 2020 number of cameras installed in my country will increase to 626 million. The rapid growth of monitoring equipment is accompanied by problem of storing monitoring data.
01. Storage space is growing rapidly
According to current norms and standards of technical protection, general purpose video surveillance system must continuously collect data for 7x24 hours, and storage time of this data must be at least 30 days. Keep longer. This means that huge amounts of video data need to be stored.
02. The storage system requires high scalability
Due to continuous development of video surveillance project itself, system will be regularly expanded and updated online, which requires a high degree of scalability from storage system, and storage devices can be added to system simply and conveniently. .
03. Requirements for Centralized Management
In security monitoring applications, due to need for a large number of storage devices, it is necessary to efficiently manage huge data on storage devices in order to provide convenient, reliable and transparent support for use by end users.
Cloud storage, hand shot for data storage monitoring
Cloud storage is a system consisting of network devices, storage devices, application software, servers, access interfaces, and other components. With storage devices as its core, it provides customers with data storage and business access through application software.
Cloud storage is gradually being adopted in field of video surveillance. Compared with traditional storage methods, it can not only solve problem of storing large amounts of data, but also has other obvious advantages.
01. Economic advantage
Users use cloud storage not to use a specific storage device, but to use data access service provided by entire cloud storage system. Thus, users no longer need to invest in internal storage devices such as servers and hard drives, but only need to invest a portion of service fee, which greatly reduces cost of investment.
02. Smart storage and higher efficiency
Cloud storage solves problem of wasted disk space through virtualization technology, can automatically redistribute data, and improve disk space utilization.
03. Faster search
Cloud storage can provide a centralized management tool for multiple devices based on cluster management technology, with functions such as centralized hardware monitoring, cluster management, system software and hardware status monitoring, active alarm, and graphical system detection.
04, High system redundancy, security
If online storage system fails, hot spare computer can immediately take over service. After failure is resolved, service and data will be moved back; if it is necessary to recall data of failed computer, disk of failed machine can be inserted into cold standby machine to realize immediate access to all data.
The large volume of video data in security industry determines that cloud storage is an inevitable security trend, but some issues need to be addressed in order to realize a real combination of cloud storage and security industry.
For example, problems with broadband access. Only when broadband access network is fully developed will users be able to obtain sufficient data transmission capacity, realize large-scale data transmission, and truly enjoy cloud storage services. Otherwise, it can only be empty talk.
