All industries are feeling the technological transformation of the surveillance industry. The increasing data retention times and new HD cameras combined with advanced analytical systems have made traditional surveillance infrastructure ineffective and costly.
While this has put pressure on the current surveillance architectures, there is an upside to it for visionary companies that are utilizing their surveillance solution to get more than just improved security.
IP and HD Camera Revolution
Since the introduction of IP phones in the 1990s, the industry has consistently been moving from analog system to digital networks systems. Cameras have also improved to include on-board analytical systems, faster frame rates and higher resolutions. This has resulted in a massive increase in the size of video footage per security camera.
There are more IP and HD cameras today than ever before. Compounded by the threat of terrorism, the use of camera now includes not just surveillance of building premises and roads, but also surveillance of streets as well. According to IHS, High definition camera shipments are projected to grow by a compounded growth rate of 43% from 2014 to 2019. It is estimated that by 2020, there will be over 3 trillion hours of captured surveillance footage. This will result in production and storage of 859 petabytes of surveillance data every day.
Shifting form Surveillance Images to Video-Based Data.
Surveillance solutions that were once considered distinct and separate are now being integrated within the IT infrastructure. This has been largely due to the faster data transfer technologies in the IT networking infrastructures. These have made it possible for surveillance footage to be accessible remotely, in real time and centrally. Comapnies can now monitor all thier global investmenta cetnrally.
As video analysis applications are becoming richer in features, businesses have found business critical values in the security camera video footage. Retail stores are using the video to make informed decision on buyer habits and behaviors. They have been able to then decide on how best to position their products. Logistic companies are now able to track their cargo through ports and rail yards for greater efficiency.
They have been able to turn what was traditionally a security cost to a business analysis tool. An investment that not only kept the business and clients safe, but has also increased profitability.
However, for the video footage to make statistical sense, it has to be collected over a period of time and stored somewhere it can be accessed easily. This requires storage systems that are fast and cost-effective to store the data for long period of time without any performance degradation. These means there has to be a smarter way to store data than other than using the legacy Network Video Recorders (NVR). Storage servers can no longer be cost effective when storing the HD camera footage as they quickly become expensive and difficult to manage.
Storing data on cost effective mediums is important, but it should be done without negatively affecting accessibility. The storage infrastructure should provide visibility to the data at all times while still managing access permissions to ensure controlled, authorized and secure access to the data at all times.
The storage infrastructure should be able to support both legacy and modern video management systems seamlessly. It must also support all major IT platforms and architectures used to transfer and access that data.
Aim for a Single File System View and Layered Architecture
The solution to these new challenges is to use a Single File System View and Layered Architecture approach. This where data is systematically grouped on the frequency of it use. Data that is accessed often should be stored in high performing disks. Data whose rate of access is medium should be stored in the premium storage cloud services. Data that is less used should then be stored in standard cloud storage or tape.
Because a system automatically manages the data and classifies it automatically, the storage system will be efficient, scalable and efficient. It will be able to protect people and property, be efficient to use and still give maximum business value to the investor.
