The perfect combination of network video surveillance and high-definition storage makes the national

 

Throughout the national security exhibition in the first half of 2012, HD surveillance has undoubtedly become the "protagonist" of the security market. While the well-known domestic security manufacturers are promoting the full range of high-definition products, they are also actively promoting cases where high-definition monitoring has been applied, which indicates that the application of high-definition monitoring has risen in the limelight. As security exhibitions continue to be held, high-definition technology is constantly being demonstrated, and high-definition storage is taking advantage of it, bringing great convenience to the development of the monitoring industry.
 
High-definition video surveillance, as a vane for the development and improvement of video surveillance systems, has occupied a very important position in the entire field. High-definition monitoring system not only presents perfect results for users, but also puts forward higher requirements on peripheral equipment such as storage and transmission. The capacity of high-definition surveillance data storage media has increased exponentially, bringing possibilities for mass storage. Another pressure of the normal operation of the HD surveillance system is to solve the problem of storage space. The storage space occupied by HD storage is at least 3-5 times the storage space of the ordinary 4CIF format encoding method. Therefore, a larger HD surveillance system is required. Backed by disk storage space.
 
Current HD storage can be roughly divided into centralized storage and distributed storage. The centralized storage method has the problems of convenient management and maintenance and low overall system cost, but also has many problems such as excessive one-time investment and high bandwidth requirements. If the distributed storage method is adopted, there will be problems such as inconvenience to unified management and high overall investment. The centralized monitoring system is easy to manage, and the distributed storage monitoring system is convenient for playback and query of food data. Both methods have advantages and disadvantages, so in some large-scale monitoring systems, more and more solutions choose to focus on centralized and distributed storage. Unified deployment, which not only facilitates management, but also facilitates data playback and query, while reducing the system's requirements for bandwidth.
 
常用 The common storage methods in security systems include DAS direct connection, NAS network hard disk, and IPSAN architecture. DAS has been widely used in small monitoring systems with its low cost, simple configuration, mature transmission scheme, and RAID array technology. IPSAN adopts IP-based network transmission storage network, which has good scalability, sharing, and information data security. It is one of the most commonly used implementation methods for centralized storage in large-scale monitoring systems. The NAS network-attached storage method can easily implement distributed network storage with the characteristics of moderate price and convenient installation, which makes up for the shortcomings of the above two storage solutions and is suitable for medium-sized network monitoring systems.
