With 60 percent of all of the world’s data expected to be created and managed by enterprises by 2025 according to IDC, it’s not surprising to learn that enterprise players have moved swiftly to help their customers and organisations maximise the opportunity around this massive data growth.

However, when it comes to one of the most significant drivers of this growth in information—surveillance data— many enterprises struggle to understand how they can apply it to do more for their business. In an age when data is fast becoming the lifeblood of the business world, these players are intuitively aware of the great potential surveillance data holds for them, but they lack an understanding of exactly how to tap into that potential.

Part of the reason for this is that the nature of video surveillance has changed in recent years. Once regarded as an isolated, security-specific function, surveillance today is more properly understood to be a source for maintaining business continuity. Traditionally, video has helped support safety and security measures, and has also provided a layer of accountability and insurance. Transformed by mobility, the cloud and big data, video surveillance data is booming, and can now serve as a strategic system for business outcomes that go beyond addressing only security needs.

Applications for video data

Video is proving to be a goldmine for improving operational efficiency and marketing opportunities, as well as creating new business value. For example, video data can help airports analyse flow patterns and wait times to deliver better services that create a more positive travel experience. Or, consider retail, where end-to-end video surveillance that captures data at all points of the retail experience—from supply chain processes to how store shelves are stocked—can help reduce waste, enable stores to better manage stock levels and help drive better sales.

To reap the full benefits of video surveillance data, a business must accurately plan and architect its storage systems to accommodate current and future growth, along with potential future uses for the data. At the heart of this planning are three fundamental questions to address: 

  • Where can I store digital video surveillance data?
  • How can I cost-effectively store it for an indeterminate amount of time?
  • How can I ensure the right people from across the company have access when they need it?

This shift from a one-size-fits-all, set-it-and-leave-it proposition to a model that accounts for data growth and subsequent requirements requires a radically different approach to video surveillance storage. The right storage architecture must be tuned to the specific business needs it is addressing, both today and in the future.

Technology trends are reducing the costs of camera technology, making it possible for organisations to incorporate more high-quality cameras

Best practices for video surveillance data

The good news: Similar challenges have been tackled in other arenas, including traditional IT data centers. In these settings, data is the primary driver for how everything is architected, designed and operated. The primary goal is to store data effectively and efficiently while protecting it.

The same holds true now with video surveillance data. Best practices from the data centre arena demonstrate how the right architectural planning can enable organisations to accommodate data growth and still access what they need, and when they need it. The right architecture can also help turn video into a value engine for new business opportunities, like helping ensure the efficient operational flow of people and products, and informing more direct and tailored marketing and sales efforts.

Several key steps can help achieve this.

Expect growth, and plan to accommodate it

Three factors are driving today’s video surveillance data growth: The number of cameras used by an enterprise and the type of cameras used, along with requirements pertaining to how long enterprises must retain data collected by those cameras. Specifically, technology trends are reducing the costs of camera technology, leveling the playing field and making it possible for organisations to incorporate more high-quality cameras into their surveillance systems. These higher-quality cameras, in turn, generate more data for enterprises to manage. This, coupled with the fact that retention requirements—largely driven by regulations, insurance needs and other legal implications—are shifting from weeks to years, means enterprises must balance today’s needs with tomorrow’s anticipated growth.

Enterprises can successfully achieve this balance by establishing a growth model for video data and choosing a storage system that meets their current needs and can easily scale to accommodate future growth. Key things to look for in systems meeting these requirements include technology architectures that enable an organisation to start with the smallest possible system without sacrificing on features, and ones that are built to take advantage of hard drive innovations and allow for the seamless addition of incremental storage technology as needed

Anticipate every situation—including when things go wrong

The shifting use of video surveillance and its ability to maintain business continuity means video surveillance systems must remain highly available to record and capture data. However, system growth increases the number of moving parts and the potential for associated devices, like hard drives, to fail. Enterprises can minimise risk by treating their video data as the final measure of security, and planning everything around it. Making data the focus can ensure an enterprise can continue to record and access surveillance data, even when components fail.

Organisations should seek out systems designed to not only anticipate failures, but also to quickly recover from them if they occur, and include features like proactive failure detection, fast failure recovery and preemptive fixes to assure data availability. Systems designed with data as the central focus can handle component failures without video loss and are also able to recover fast from one failure before a second one can occur.

Plan for the longevity of data

Regardless of retention requirements associated with video surveillance policies, enterprises should account for the possibility that they must retain at least some video data for years. To prepare, an organisation should adopt a multi-tiered storage architecture so not all data is stored in one highly-available, high-performance, cost-intensive tier, as not all video needs to always “travel first class.” A hierarchical storage system that moves older video data to a lower-cost storage tier is ideal for handling video archiving.

Adopt an open architecture

As technology continues to evolve, enterprises should adopt an open architecture featuring a modular design. This will enable businesses to easily update individual parts in line with future technology trends without significantly disrupting the system’s overall architecture. For example, hard drive technology advances increase capacity and drive down the cost of drives. Changes in cameras and VMS software may increase bandwidth needs of storage. A storage system must take advantage of these advances without requiring wholesale hardware replacement every time things change and evolve.

We have already seen video surveillance evolve from an isolated application to one that can contribute to an organisation’s bottom line with the right architectural support and planning. What the future holds beyond this evolution is anyone’s guess, but organisations can set themselves up for continued benefits by adopting a storage system that supports the open and seamless interface for data access needs of future applications, such as artificial intelligence and predictive analytics. Ultimately, having a plan for all data uses—including the non-traditional surveillance uses—helps ensure an enterprise is able to squeeze as much value out of its data as possible.

Has the gap closed between security fiction and security reality?
Has the gap closed between security fiction and security reality?

Among its many uses and benefits, technology is a handy tool in the fantasy world of movie and television thrillers. We all know the scene: a vital plot point depends on having just the right super-duper gadget to locate a suspect or to get past a locked door. In movies and TV, face recognition is more a super power than a technical function. Video footage can be magically enhanced to provide a perfect image of a license plate number. We have all shaken our heads in disbelief, and yet, our industry’s technical capabilities are improving every day. Are we approaching a day when the “enhanced” view of technology in movies and TV is closer to the truth? We asked this week’s Expert Panel Roundtable: How much has the gap closed between the reality of security system capabilities and what you see on TV (or at the movies)?

BCDVideo signs OEM deal with Dell EMC: positive impact for surveillance storage

In a significant move for the video security market, BCDVideo has announced that it is set to become Dell EMC’s OEM partner in the video surveillance space. For nearly a decade, the Chicago-based company has been known as a key OEM partner of Hewlett Packard Enterprise (HPE), providing storage and networking technology to security integrators on a global scale. This latest partnership will allow BCDVideo to take their offerings to the next level. BCDVideo Vice President Tom Larson spoke to SourceSecurity.com to discuss the reasoning behind the deal, and how the programme will benefit partners, integrators, and end-users alike. Expanding BCDVideo's product offering For BCDVideo, the HPE OEM programme has been widely acknowledged as a success, allowing the company to leverage a globally recognised brand and provide high-quality, reliable solutions across video networking and access control. Nevertheless, explains Larson, HPE server solutions are primarily suited to large-scale enterprise projects, and are therefore unable to accommodate for the growth in small- and medium-sized surveillance applications. The global collaboration with Dell EMC will allow BCDVideo to open up a broader product offering, building on success in the larger enterprise market to offer tailored solutions to SMEs. Our aim is to look at all best of breed technology to serve the video surveillance marketplace, and that means multiple partnerships” Support for integrators By leveraging Dell EMC’s sophisticated digital storage platforms, BCDVideo will now be able to offer a more cost-effective solution to integrators, without sacrificing the resilience and IT-level service that BCDVideo is known for. With access to Dell EMC’s expansive global sales and technical teams, the company hopes to expand its reach, all-the-while providing partners with around-the-clock technical support and a five-year on-site warranty. Customers should be reassured that BCDVideo will continue to offer HPE platforms, service, and support. “Our aim is to look at all best-of-breed technology to serve the video surveillance marketplace, and that means multiple partnerships,” says Larson.  “The addition of Dell EMC to our portfolio is a major win for BCDVideo, for Dell EMC, and for our integrators.” The global collaboration with Dell EMC will allow BCDVideo to open up a broader product offering Meeting surveillance market demands At the technology level, assures Larson, Dell EMC’s server offering is well suited to handle the increasing video resolution and growing camera count demanded by the surveillance industry. At the larger end of the spectrum, the company’s Isilon Scale-Out NAS solution can handle tens of petabytes of data, making it ideal for large-scale security applications such as city-wide surveillance and airport security. Dell EMC storage solutions are already proving successful at major international airports including Dubai and Abu Dhabi, each with a camera count in the 1000s.Dell EMC and BCDVideo together are ensuring our customers get the right solutions designed for the surveillance market” For Dell EMC, the new partnership means the ability to expand on this success in the enterprise market, leveraging BCDVideo’s surveillance expertise and high-level customer service to offer tailored solutions for lower-volume applications. Since its inception, BCDVideo has differentiated itself in the security space by providing a high level of IT service to integrators making the transition to IP systems. By combining resources, the partners will be able to service VMS and analytics companies, software vendors, and access control providers, as well as traditional business integrators. Ken Mills, General Manager Dell EMC Surveillance, explains: “Surveillance storage is not just about capacity, it is also about performance and reliability. Dell EMC and BCDVideo together are ensuring our customers get the right solutions designed for the surveillance market.” Accomodating for growth BCDVideo is well placed to accommodate this anticipated growth. Last year, the company opened a new 51,000-square-foot global headquarters in Illinois, home to 90 separate stations within their Innovation Center where each system is customised according to integrator needs. The new facility allows for expanding business with new and existing partners in the security market.

How to manage physical security data in compliance with EU GDPR
How to manage physical security data in compliance with EU GDPR

Until recently, data laws have differed from one country to the next. This meant that for those organisations conducting business or protecting assets abroad, they needed to localise both their infrastructure and policies dependant on the country they were operating in. However, with the impending arrival of the EU GDPR (General Data Protection Regulation), which comes in to force on the 25th May this year, all of that will need to change. Data management in CCTV surveillance Surprisingly, despite the fact that much has been written about the impending EU GDPR, very little attention has been devoted to the process of ensuring compliance for the operation of video surveillance, access control and other physical security systems. The EU GDPR dictates that businesses adhere to specific governance and accountability standards with regards to the processing of all data. As this includes such a large scope of data, any public or even private organisation using CCTV to monitor publicly-accessible areas must pay attention, as monitoring the public on a large scale is by default considered a high-risk activity. This includes information that shows who a person is, where they are and any other specifics about them.We have seen organisations defining corporate standards for their physical security systems based around IT standards and technologies According to numerous market research studies, many organisations are yet to take the necessary steps in order to review the new regulations and ensure the necessary changes are made to meet these obligations. To date, we have seen organisations defining corporate standards for their physical security systems based around IT standards and technologies. With the implementation deadline of the new regulations fast approaching, these should be in a better state of readiness, with standardised processes, common organisational approach and technology. Enhancing industry awareness of compliance  What’s more, a lot of legacy systems or disparate systems are still out there, and these may still have been entirely commissioned and operated by location-specific security teams. Regardless as to where your organisation stands in terms of technology, it is important to participate in the GDPR review with a greater sense of urgency.  The EU GDPR dictates that businesses adhere to specific governance and accountability standards with regards to the processing of all data Tony Porter, the UK’s Surveillance Camera Commissioner, has been incredibly vocal in recent months with regards to making security system operators aware that their activities will be subject to the GDPR and to signpost them to relevant guidance from the ICO. For those actively seeking to ensure their businesses are compliant, his organisation’s independent third-party certification is a great place to start. However, with just a few months until the regulation comes into force, it is unfortunate that his organisation is not yet in a position to confirm this will be sufficient to demonstrate compliance with the EU GDPR. Ensuring regulatory preparedness With this being said, there are still a number of steps organisations can take to ensure they are well-prepared when the law comes into play: Get involved in the GDPR discussion If you haven’t already, proactively initiate a GDPR discussion with your legal team and ask for their guidance. Conduct a gap analysis to identify what works and what might require improvement in accordance with the new regulation. Then engage your consultants, integrators and manufacturers who should be able to advise on appropriate solutions. In the vast majority of cases, it should be possible to upgrade the existing system rather than ‘rip out and replace’.The appropriate use of encryption and automated privacy tools is a logical step Adopt privacy by design Under the terms of the EU GDPR, data that is anonymised or pseudonymised is likely to be low-risk. The appropriate use of encryption and automated privacy tools is therefore a logical step. For example, video redaction that blurs out people’s faces in video unless there is a legitimate reason to reveal their identity can minimise the dangers of having security cameras deployed in public spaces. Seek out certified and sanctioned organisations, such as the European Privacy Seal group ‘EuroPriSe’, a professional organisation whose purpose is to ensure companies meet the ‘GDPR-ready’ privacy compliance standards. Consider cloud-based services Owners of on-premises video surveillance, access control or ANPR systems are responsible for all aspects of EU GDPR compliance, including securing access to the systems and servers storing the information. However, by working with an approved cloud provider it is possible to offload some of these responsibilities. For example, we partner with Microsoft Azure to offer these systems ‘as a service’. This pathway significantly reduces the customer’s scope of activities required to ensure compliance and is highly cost-effective. Yet it is important to realise it isn’t a full abdication of responsibility. You remain accountable for ensuring data is classified correctly and share responsibility for managing users and end-point devices.  With data laws changing around the world, businesses need to seriously consider how their security technology investments will help them manage risks in order to keep pace. With the GDPR deadline approaching, it is the ideal time to re-evaluate practices, partner with forward-thinking vendors and adopt technologies that will help meet privacy and data protection laws. This way, businesses can minimise risk, avoid costly penalties and be ready for anything.
