6 Overview of cloud storage in visual surveillance
The large-scale deployment of visual surveillance systems has contributed to the explosive growth of
surveillance video data. It induces stringent needs for the efficient storage of massive video data and fast
access of information of interest to users. Cloud storage is a data storage model for enabling service users to
have ubiquitous, convenient and on-demand network access to a shared pool of configurable storage
resources, which can be rapidly provisioned and released with minimal management effort or service-
provider interaction. In the cloud storage system, the physical and virtual resources can be dynamically
assigned and reassigned according to the users' demands.

7 Functional architecture for cloud storage in visual surveillance

7.1 Architectural framework

Figure 7-1 shows the architectural framework for cloud storage in visual surveillance. The cloud storage based
visual surveillance platform consists of two parts, which are respectively the traditional visual surveillance
(VS) system and the cloud storage system. The cloud storage system can also be integrated with intelligent
visual surveillance, mobile visual surveillance and other visual surveillance subsystems and the architecture
is similar to that defined in this clause and is not described in this Recommendation.
