New RAID technology in security data storage
In recent years, with the continuous development of information technology and the popularization and application of security products and systems, data security issues in the security industry have been receiving increasing attention. With the rapid development of high-definition surveillance, a large number of large-scale projects such as safe cities and smart cities are spreading out, and the amount of data continues to increase. The storage problems and data security issues under the big data are gradually becoming video network surveillance. New topics in the field.
The storage of installed data is accompanied by the joint development of security technology and storage technology. It has successively experienced the stages of analog front end + DVR storage, analog front end + DVS / DVR + network storage, network front end + NVR, network front end + network storage, etc. Nowadays, with the increase of network bandwidth, high-definition applications are becoming more and more common, which puts forward higher requirements for security storage systems.
1. New requirements for security data storage
The characteristics of current security development can be summarized as the following three points:
1) HD
l High line simulation: 600/650/700 line analog camera + high resolution DVR
l Digital HD: SDI / HDSDI, HDCCTV
l HD network: 1.3 million / 2 million / 5 million IPC + HDVR + NVR, 4K applications
2) Intelligent
l Engage in post-accounting, passive application transition to pre-control and proactive defense, further liberate manpower and improve efficiency
l From the technical level of intelligent analysis into the actual application stage, such as perimeter defense, personnel tracking, etc., has been used in public security, transportation, finance, judicial and other industries
3) Converged applications
From single-system independent use to multi-system platform integration use stage, mainly manifested as
Large-capacity video information collection and sharing
Internal integration of security system, docking with upper-level business management system
Multi-system integration, such as emergency linkage, emergency deployment, public security and fire protection, etc.
Security and IT technology are highly integrated
According to the new requirements of the current security system, the requirements for the security storage system can be summarized as shown below.
