scope:

This Recommendation describes the brief functional model, application scenarios and requirements for cloud storage in visual surveillance (VS) systems, based on the requirements and architectures defined by [ITU-T F.743], [ITU-T H.626] and [ITU-T H.626.1].

A visual surveillance service is a telecommunication service focusing on video (and audio) application technology, which is used to remotely capture multimedia (e.g., audio, video, image, various alarm signals), and present this to end users in a friendly manner (including accessibility aspects), based on a broadband network with ensured quality, security and reliability. 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 cloud storage systems, the physical and virtual resources can be dynamically assigned and reassigned according to user demand. Cloud storage can realize scalable, flexible and reliable data storage for large-scale visual surveillance.
