Since the promotion of intelligent architecture, the upgrading and improvement of storage technology has been the focus of attention in the industry. With the wide application of NVR network video surveillance technology, various requirements such as the security and reliability of video data storage have become increasingly prominent. There is also an urgent need for video data storage. NAS storage technology has become the best choice for video surveillance storage systems.
The device is mainly based on NAS storage technology. It converts real-time data (analog signals) collected by front-end devices (cameras) into digital signals through video servers and stores them in NAS network storage devices to ensure data security. Compared with the traditional single-machine backup system, this type of storage backup architecture has the advantages of being more reliable, safer, and more convenient to operate.
As a network video surveillance system, NVR eliminates the need for cumbersome cabling design, makes full use of network resources, and enables remote management using the network. His disadvantage is that there is no storage terminal to store its video data, and the storage device NAS that also uses network resources is undoubtedly the best partner of NVR. The NAS is an independent storage device that uses network cables to connect and read and write data.
The NAS solution in the NVR system incorporates the Free NAS as an independent storage device in the existing NVR network monitoring system to store the recording data generated in the NVR system. The free é4020 is used for data storage. At the same time, the storage mode is set to Raid5. Even if any disk in the NAS is accidentally damaged, the data is not lost. Just re-insert a new disk system can be automatically repaired. In order to ensure the validity of the data. The effective disk capacity of this solution is N-1, but this model is safe and recommended.
NAS storage technology remedies the problems of traditional storage technologies and focuses on the following aspects:
First of all, in a video acquisition system composed of a plurality of hard disk video recorders, since the amount of video data collected by each hard disk video recorder varies greatly every day, the system resource utilization rate is unbalanced, and overall performance and efficiency are degraded. As an independent storage system, NAS adopts centralized storage technology. Each terminal in the system reads and writes data from the disk array. The continuous and flexible storage system operation mode can effectively increase the efficiency of system resources usage and reasonably balance the workload and achieve rapid data sharing. At the same time, NAS technology adopts IP network channels to form a separate storage network, which effectively improves the read/write speed of data and improves the reliability of system operation.
The NAS system has good scalability. At the same time, centralized storage, centralized management, and decentralized management are adopted (you can set different permissions for different users, thereby avoiding intentional or unintentional misoperation, resulting in data loss). The model makes the system architecture highly integrated, and the end user does not need to perform any operations on the storage system. The system also has the performance of fast data sharing. With only one server, all video data can be managed in a unified manner, effectively reducing operating costs such as hardware and personnel.
As a security system, the confidentiality of NVR's own data is also very important. The video data is stored in the free 4020 hard disk. If the free 4020 or its internal hard disk is stolen, can the theft be installed in the PC to steal its video data? the answer is negative! As long as the hard drive in the free 4020 is taken out and inserted in the PC, the PC will read the hard disk as if it were a new hard disk, and it requires formatting. In other words, even if the Free 4020 or the hard disk is stolen, the video data will not be leaked.
From the above discussion, it is not difficult to see that the Free 4020 can be used as a central memory in a small and medium-sized NVR system. For formal applications, NVR server + Free NAS network storage device solution is recommended when free data storage is used. This is because NAS is a specialized device designed for storing/backup data and its data processing. The capacity and speed are much lower than those of file servers. This is because they are used for different purposes. In a multi-concurrent application environment, the disks inside the NAS are composed of RAID 5 arrays through the combined application of NAS+NVR servers. It is used to store data and synthesize the characteristics of both to achieve better security of data.
