Video Surveillance cameras installed in year 2015 generated 566 Petabytes of data on daily basis. This was revealed in IHS new survey carried out in early 2016. To put into a clear perspective, the generated data is equal to 11.3 million standard double layer Blu-Ray movie discs. And can amount to twice of all user data stored by Facebook. Also the said amount of data can equal to all Netflix’s users streaming 1.2 hours of HD resolution content on a simultaneous note.
According to IHS records, newly installed surveillance cameras generated 413 Petabytes of data a day. Now, with the latest estimate on hand, IHS predicts that by the end of 2019, new security cameras will be generating more than 815 Petabytes( or 3 trillion hours of surveillance video) of data on daily basis.
One of the main reasons due to the projected increase is due to the fact that, video surveillance market is still not saturated. The IHS report on the installed base for video surveillance equipment suggested that there was one camera installed for every 29 people on planet. However, as camera density varies drastically by country, the figures might slightly differ.
The research conducted in surveillance matured markets such as UK and US suggests that one camera is installed for every 8 to 11 people respectively. Emerging markets such as Asian countries like India, Singapore and Malaysia suggest 1 camera for every 150 people. Middle East and Africa have cameras installed one for every 200 people.
The survey further stated that
- IHS survey report suggests that HD complaint 1080p 25/30 fps cameras have established themselves as the minimum anticipate from new cameras. The survey also confirmed that HD CCTV has emerged as the replacement for many remaining standard definition analog cameras.
- Panoramic and 4K cameras are two further storage hungry high growth product categories.
- When video surveillance footage is being stored it is generally being retained for an increasing period of time. Aside from out and out security purposes, video surveillance footage is being increasingly retained longer for anti-litigation, insurance and operational purposes.
According to Josh Woodhouse, senior market analyst for video surveillance at IHS feels that the amount of data produced by video surveillance cameras is huge yet it is often overlooked in analysis of general worldwide data production and storage. This may be due to the fact that video surveillance industry is still below the radar for those involved in data storage, perhaps due to its characteristics and challenges. Management and storage of potentially hundreds of high resolution video streams can be one such challenge. Large throughput capacities as well as a heavy write focus are just two qualities of enterprise storage tailored for video surveillance workloads. The convergence of traditional separation of security plus IT has been slow.
However, increased surveillance storage demands may force many end users to re-access their storage solutions as all those past approaches will no longer be adequate.
If enterprise storage is used, Woodhouse said the majority of demand at present is being fulfilled by IP SANs.
Chinese video surveillance vendors are well positioned to ramp-up their offerings of low-priced, high capacity SAN systems to meet the capacity requirements of the mass video surveillance market. This approach, previously reserved for only the largest installations, is filtering down to smaller systems.
However, the market is also evolving. Concurrently, some larger installations have progressed to the use of smarter storage architectures integrating moving data between edge and core storage, between multiple tiers (in some cases storage media) within single platforms which are all viewable in the VMS.
Woodhouse believes current IT megatrends such as hyper-convergence, virtualization and software defined storage are still a long way off from affecting the majority of video surveillance installations. Yet, improvements in the efficiency of how recorded footage is managed throughout its lifetime are beginning to drive new approaches to video surveillance storage design.
This is critical to keep up with the video surveillance data deluge.
So, where do you think video surveillance field will head in this year?
