Smart Security: monitoring storage technical characteristics and prospects

Network monitoring is born solves the traditional monitoring effects of difficulties, has changed the traditional way of connection, simpler and more convenient, but also derived a huge storage requirements and higher bandwidth.

Video storage development process

Video monitoring technology development process is divided into analog video surveillance, digital video surveillance and monitoring of network video, analog video surveillance storage device is the era of video tape recorder (VCR); digital video surveillance age represents the product is a digital video recorder (DVR), internal or external hard disk is the primary storage device at the network video monitoring, network cameras, encoders for video encoding for the transport and storage mainly uses the network video recorder, NVR, NVR with a variety of storage, such as DAS, SAN, optional.

In network video monitoring period, the data is stored for explosive growth, have become diversified, the different storage structures have been applied, DAS, NAS, FCSAN and storage system, such as IPSAN and digital network video monitoring system with applications for video data of mass, high-speed, real-time, stable storage and retrieval.

In digital video monitoring period, the DVR as a digital storage device, usually the storage mode is the built-in large capacity hard disk block implements storage expansion, or by extending the interface external disk arrays, understandable way for DAS storage.

DAS schema stored in the early days of single point and small-scale DVR system, because the deployment easy, cost is not high to be widely used, this mode features a single-server (DVR) private storage space.

Video storage features

Video storage is a network video monitoring system application is very important.

Mass of video data often need to be stored for a long time, and for the future of information retrieval, video playback, and so on. The user can retrieve the system-supplied application interface, a road, a time period of surveillance video playback to retrieve, or export a Makefile. From tape to disk from IDE to SAS interfaces, from single disk, JBOD to various RAID technology, from DAS to NAS, SAN, storage areas and every technological changes have contributed video storage areas corresponding development.

Video surveillance in the area of storage and civil areas (such as video site) video storage applications, the civilian areas of the video and TV main means of storage, network, video, etc, it will video files stored on the server, and then network users access to the video server for video streaming, therefore, primarily video live or on-demand, from the storage device "read" and play the video.

And monitoring areas of video storage is the process of "write", is a network of video data is written to the disk array conducting the process of saving or backing up, of course, in the course of the write is also complicated by a certain percentage of the operation "read", i.e. the network users on video video playback request operation.

Video monitoring system using storage devices in the data on a read-write and other types of different characteristics.

Video surveillance system generally has more monitoring points (camera number), video streaming and storage time, 24 hours continuous non-stop job characteristics. Video surveillance application mainly video code stream for write, specific characteristics are as follows:

Video data is streaming into the storage device or from a storage device for playback, and traditional file reading and writing.

Multi-channel video long time while writing the same storage device, storage system can work long-term stability.

Real-time multi-channel video written request storage system with high bandwidth and constant.

Huge storage capacity requirements scale performance requirements for replacement of the faulty device or expansion.

Multiple concurrent read and write on the storage device performance requirements are very high.

Monitoring storage of future

You cannot fail to mention store about cloud storage, this is a very intriguing storage technology, cloud storage can implement storage fully virtualized, greatly simplify application link, saving customers construction costs, while providing more storage and sharing capabilities.

Cloud storage all device users fully transparent, any place, any authorized user can access through a single line and cloud storage connection, space and data access. Users do not need to care about storage device model number, quantity, network infrastructure, storage protocols, application interfaces, application of simple transparency.

Monitor cloud storage, break through the traditional storage performance and capacity bottlenecks, cloud storage providers to join the network in a variety of different types of storage devices to form a powerful storage capacity the exception, for performance and capacity of linear scaling for mass data storage becomes possible, so that the enterprise has the equivalent of whole cloud storage capacity to successfully solve storage problems.

With the cloud Conference manufacturers provided monitoring cloud storage service, enterprises are expected to emerge from the hardware storage device multi-million, reduce in system maintenance expenditure, on the human, quickly relieve the financial pressure, enhance the competitiveness of enterprises.

By then, users simply pay a small amount of storage costs, will be able to put the extra data exists in the clouds, and set permissions as needed, anytime, anywhere sharing related to the need to share, to reduce data transfer times, with manufacturers more excellent encryption technology, to avoid the transfer process caused by packet loss, leakage, etc. of production, guarantee the security of your data.

As the security monitoring technology and user needs of increasingly obvious that the trend of security monitoring product integration implementation process, storage technology must constantly adapt to the characteristics of application security monitoring, continuous improvement of its own, storage and security monitoring technology integration is the trend of the times.

Monitor cloud storage system is a storage and monitoring phase fusion products confirmed this trend.
