. Video surveillance storage represented in recent years by VHS, DVR, NVR, among other storage servers and IP solutions, is facing a new transformation today.
In Spain, for example, according to a recent study by the consultancy IDC, Cloud Computing has ceased to be a phenomenon to become a reality, and despite reports indicating that there are still poorly defined cloud strategies, forecasts speak of this market in that country growing by 42% in 2011.
Similarly, according to the report "IDC Latin America Semiannual IT Services Tracker, 2010", also published by IDC, during 2011 the Latin American it services market will reach a value of US $ 22,400 million. On the one hand, the modernization of legacy applications encompasses more and more solutions, and on the other, the increase in virtualization, consolidation and optimization of Datacenters is paving the way for the adoption of Cloud Computing as a business model.
Would it be possible to argue that video surveillance is taking advantage of this new storage model? According to the consultancy, having overcome the limitations of CCTV deployments and making the leap to the digital world, IP videoconferencing has the ingredients to take advantage of this model either as a public cloud , in which the speed of video frames is lower but allows the storage of backups with the available bandwidth, or in the private cloud , where users must bear the cost to manage it, but which facilitates server virtualization, real-time resource monitoring, and service provisioning automation.
However, one of the biggest fears remains security. Currently, there are mechanisms to solve these problems that range from state-of-the-art perimeter security to new AES 128-bit encryption systems and rigorous service level agreements (SLAs) with the respective cloud service providers.
Thus, a cloud-based solution would be becoming an attractive alternative for enterprise customers, because in addition to its services, companies would minimize expenses represented in energy savings, cooling and the costs of managing their own data centers. In this way, the public sector, transport and banks would be according to IDC, the early-adopters of cloud for its intensive use of IP video surveillance.
For William Rhodes, a market analyst, most enterprise customers store video surveillance data, at a maximum frame rate, for 30, 60 or 90 days. However, "segments such as pharmaceuticals require storage for up to five years, albeit at a slower rate. For them, a public cloud solution could be the answer." However, the other option is the private cloud because despite the cost, "users will have greater control over the security policies and flexibility of the system," Rhodes added.
