Video surveillance industry has been evolving from time to time and the best example mirroring this transition is seen in the form of new camera technologies, increasing data retention times and more advanced analytics which is doing more harm than good by putting pressure on current surveillance architectures.
Actually the upside is incredible, especially for forward thinking companies seeking more from their surveillance solutions than just improved security and a deter to crime.
Technically speaking, surveillance has come a long way transforming from analog to digital and camera technology also continues to get smarter-with on-board analytics, higher resolutions, faster frame rates- resulting in a massive increase in video data, and with it, escalating the need for better storage infrastructures.
According to the latest figures suggested by IHS, around 566 Petabytes of data was generated by surveillance cameras on daily basis in 2015. And out of the said number, new camera installations involving HD and MP cameras generated 413 Petabytes of data a day. If these estimates are to be believed, then new security cameras will be generating more than 859 PB of data by 2019 on a daily note.
Furthermore, as video analytics applications like Facial recognition and LPR become more feature rich and sophisticated, non-traditional business units are taking notice that video- when integrated and correlated with data from other systems-can be used to make better decisions.
For example, Logistics companies are using video data to track cargo through ports and rail yards. This is to improve their work efficiency. Retail companies on the other hand are using videos to observe where the shoppers are spending time in their premises and what products are gaining attention the most.
Thus, video data captured by security cameras is being used to improve business outcomes. Therefore, in order to realize the value of the video data, businesses need to store data for long time.
And that requires a storage infrastructure capable of providing cost-effective, long term retention of data without sacrificing performance. The demand makes sense and that is because the entire surveillance infrastructure capable of delivering maximum business value rests on a firm foundation of “intelligent” storage. And the video storage must be elastic enough to support future growth of cameras.
Therefore here’s a list of requirements which have to be available in the intelligent video storage
- It must be flexible to handle growth.
- It must be able to grow as litigation and regulatory requirements drive changes in retention policies.
- It must adapt to new image formats when needed.
- And must easily scale in size as sensor and stream counts increase and new cameras are added to the network.
- And last but not least, must be easy on the pocket.
In coming days, sophistication in surveillance will improve. But at the same time, budgets remain tight and flat. This is where controlling costs will be vital.More money will need to be spent on adding and upgrading cameras; therefore, less will be available for other components of the infrastructure.
To minimize storage costs, the storage management system must keep content at the most cost-efficient medium of storage, as well as manage the movement of the data according to policy-based criteria.
High priority, frequently-used files should be stored on high-performance disk while lower priority files should be stored on tape or in the cloud.
This is where multi-tiered architecture with a single file system view emerges as the best approach to manage video data of current day surveillance systems. Basically this architecture consists of high performance disk, secondary disk, tape and cloud storage viewed as a single file system which allows cost effectively retain data for a long tome and to be retrieved quickly and easily for analysis when needed. With this approach the system manages the movement of the data between tiers and the metadata remains intact.
DNF Security, a business unit of DNF Corporation understands the latest trends of surveillance industry. For this reason, after analyzing the current needs prevailing in the video surveillance industry, it is offering a Cloud Connection on all its Falcon series of Video Storage appliances.
By integrating the video storage appliances to a cloud, users can get rewarded with utmost savings. The hot data or the frequently accessed data can be stored on the appliance and the cold data i.e. the not so frequently accessed data can be moved to cloud platform.
And remember, customers will be charged for the data which is retrieved.
