Cloud computing exerting Force monitoring application

With the development of digital and network technology, the concept of "cloud" is more and more present around us. And with the Public security Social Security video surveillance system multi-level large-scale networking, mass data processing needs more and more urgent, cloud technology is also more and more used in video surveillance system.

Some monitoring enterprises have put forward the concept of "cloud monitoring" and "cloud service" in time. So, how will cloud technology be used in the construction of Public security video surveillance system? I believe many friends are very concerned about this topic. This paper analyzes the concept of "cloud monitoring".

The concept of "cloud"

The cloud is a metaphor for the web and the Internet. In the past, the cloud was used to represent the telecommunications network, which was later used to represent the abstraction of the Internet and underlying infrastructure.

Cloud technology is an increase, use, and delivery model of internet-based related services, often involving the provision of dynamically scalable and often virtualized resources over the Internet.

The concept of "cloud monitoring"

Cloud monitoring is based on the object networking model and uses cloud storage technology to meet the needs of modern monitoring. The concrete realization refers to through the cluster application, grid technology, distributed file system and other functions, video surveillance, access control, RFID radio frequency identification, intrusion alarm, fire alarm, SMS alarm, GPS satellite positioning technology through the "cloud" together to work together to carry out information exchange and communication, the completion of intelligent identification, positioning, Tracking and monitoring of monitoring management. Users can do 24 hours of seamless remote supervision through C/s, b/m and mobile device clients.

The technology architecture of "cloud monitoring"

From the view of technology architecture, cloud monitoring can be divided into four layers: perceptual layer, network layer, processing layer and application layer.

The perceptual layer is composed of sensors and sensor gateways, including camera, pickup, fingerprint, intrusion detection, smoke detection, vibration detection, temperature detection, RFID, two-dimensional code, GPS and other sensory terminals.

The network layer consists of a variety of private networks, the Internet, telephone networks and wireless communication networks.

The processing layer consists of the centralized storage service, the alarm service, the message service, the data service and so on.

The application layer is the interface of the Internet of things and users (including people, organizations and other systems), and combines with the industry demand, realizes the intelligent application of the IoT.

"Cloud storage" and its characteristics

When it comes to advanced storage technology, you can't talk about cloud storage. This is a very tempting storage technology, cloud storage can realize the full virtualization of storage, greatly simplifying the application link, saving the cost of customer construction, while providing more powerful storage and sharing capabilities. All devices in the cloud store are completely transparent to the users, and any place, any authorized user can connect to the cloud storage via a single access line and make space and data access. Users need not care about storage device model, quantity, network structure, storage protocol, application interface, etc., the application is simple and transparent. Cloud storage does not refer to a specific device, but to a collection of many storage devices and servers. Instead of using a single storage device, consumers use cloud storage to use a data access service that is brought about by the entire cloud storage system. So strictly speaking, cloud storage is not storage, but a service.

In addition, cloud storage is more of an application. Application storage is a storage device that integrates the function of application software, which not only has the function of data storage, but also has the function of application software, which can be regarded as a collection of servers and storage devices. The development of application storage technology can reduce the number of servers in cloud storage, reduce the cost of system construction, reduce the single point fault and performance bottleneck in the system, reduce the data transmission link, provide system performance and efficiency, and ensure the efficient and stable operation of the whole system.

With the help of the monitoring cloud storage service provided by the manufacturers, the users are expected to get rid of the huge investment in the hardware storage equipment, reduce the manpower expenditure on the system maintenance, quickly reduce the financial pressure and enhance the competitiveness of users and manufacturers. At that time, users only need to pay a small amount of storage costs, can be large capacity of the data in the cloud, and the need to set relevant permissions, anytime and anywhere to share to those who need to share, in reducing the time of data transmission, with the help of more excellent encryption technology manufacturers to avoid the transmission process caused by the loss of packets, leaks and other accidents, Ensure data security in a comprehensive way.

The application foreground of "cloud monitor"

Video monitoring as the main branch of the monitoring field, the amount of data on the network bandwidth consumption is very large, at present, I am afraid that is not fully equipped with data-centric conditions, cloud monitoring technology in the field of monitoring applications will go a long way, but with the rapid development of network technology, the obstacles to its promotion will be fundamentally resolved, Cloud monitoring will have a bright future.
