Digital video monitoring involves the collection, storage and use of big data. Therefore, a highly efficient video surveillance system must have an efficient data storage system, which is related to the efficiency of data management, data security and the efficiency of data utilization. Then, in the telecommunications level of digital monitoring system, the data storage system requirements, generally speaking, to meet the requirements of six aspects.

 

One of the important characteristics of Telecom digital monitoring system is the front-end application a lot of focus on the data storage and decentralization. Therefore, the storage system must have a strong ability of data transmission, otherwise it will affect the efficiency of data storage and utilization.

 

Mass data storage needs and rapid growth of the characteristics of the demand for storage system must be able to meet the requirements of mass storage of telecom level data monitoring, but also must have a good performance, to cope with the rapid growth of data storage space for the expansion of demand.

 

In addition, because the monitoring system is generally required for real-time video input, so the real-time video input to the data writing ability of the disk array is higher, otherwise, in the case of the write speed is not required, the data will be concentrated in the cache, will eventually lead to a number of cache, so that the host crashes.

 

At present, surveillance video needs to be deleted after a period of time, the data is deleted, there will be a certain time interval, the data cannot be written immediately, this time the data is stored in the cache, the larger cache can ensure more data retention in the cache, waiting for the re write to the hard disk space.

 

In addition, for the telecom level system, good stability is necessary, if the lack of stability, it will give a lot of users, and even bring huge losses.

 

The huge storage requirement of telecom level determines the requirements of good management. Simple and orderly management can help users reduce the cost of operation and maintenance, but also an important guarantee for the stability of the system.
