Video Surveillance Must Modernize In Storage, Recording And On-Demand Access
Video Surveillance Must Modernize In Storage, Recording And On-Demand Access

Dollars spent by video surveillance customers must go towards ensuring high-availability capture, storage and on-demand access to live and archived video. Reaching this goal mandates high-availability of independent components – camera, network, storage (edge, external), internet connectivity, display, all Video Management Software (VMS) components and an architecture that can take advantage of this. In this note, we focus on seeing our way through to a video surveillance architecture, that provides high availability storage, access to live and stored video content. Of all options available to store recorded video, edge recording is the only one that is unaffected by network failure Edge Recording Of all options available to store recorded video, edge recording is the only one that is unaffected by network failure. This makes edge storage a must-have. But, this has some limitations at present: Edge storage capacity is limited. Edge media has a short lifetime, rated only for thousands of hours of continuous recording. Most cameras are not secure and physical damage to the camera could lead to catastrophic loss of edge stored content. As storage and compression technology evolve, the constraints imposed by (1) and (2) could go away. However, securing cameras will continue to be a barrier for most installations. Secure External Storage It is thus imperative to also store video in secure external storage. Such an architecture uses edge storage to fill in content gaps created by network, external storage outages. As edge storage technology improves, larger gaps can be filled in, but one will always need external storage. By our definition, ‘external storage’ is a solution stack that includes storage media and all software (including VMS) that provide access to this storage. Access To Live And Archived Video Access to live video can either be met by external storage or directly by the camera Every surveillance solution needs to provide access to live and archived video. Access to live video can either be met by external storage or (and) directly by the camera. All things being equal, having the camera directly provide live video access, is a higher-availability solution. There is dependence on fewer components in the chain. Solutions in the market use one of the above two approaches for access to live video. Due to limited capacity and low physical security of edge storage, it makes sense at present, to have external storage meet all requests for archive video. Thus, we are led to an architecture that has heavy dependence on external storage. Dual-Recording For high-availability, external storage must be architected with redundancy. Ideally, independent components that make up external storage – storage media, associated hardware and software (including VMS components), should be individually redundant and have smart interconnectivity. However, solutions in the market rigidly tie these components together. Failure of a single component causes failure of external storage. For e.g. hardware failure of a server causes VMS component failure AND storage failure. DR provides a smart way to provide high-availability for external storage For these solutions in the market, high-availability is achieved by having additional external storage units that step-in during outages of primary units. If these additional units continuously duplicate primary units, access gaps are minimized, and archive access is un-affected during primary unit outages. This is the idea behind Dual-Recording (DR).  To meet cost budgets, these additional units can be configured to store subsampled (framerate, resolution) video content. A small number of additional units can support concurrent outages of all primary units. A few-to-many redundancy. Rising Need For Dual-Recording Most cameras cannot be physically secured, and video content produced by a camera must be stored externally. Many VMS solutions use external storage to service live video access requests. Edge storage limitations impose restrictions on edge archive access at present. So, external storage is used to service requests for archive access too. Thus, a surveillance system ends up being over-dependent on external storage. DR provides a smart way to provide high-availability for external storage. As edge storage improves, it will be able to service archive access requests. VMS software will need to evolve, to use this capability smartly.

Impact Of Sophisticated IT Technologies On The Security Market
Impact Of Sophisticated IT Technologies On The Security Market

Over the course of the past few months, I have discussed a myriad of topics, from Big Data, the Internet of Things and emerging video surveillance-use cases, to analytics, storage complexities and IT technologies like virtualization and hyperconverged infrastructure (HCI). All of these trends have a significant effect on the security market, and in April they were highlighted in spades at ISC West. It’s great to talk about these trends but it’s far better to see how they are being leveraged in real-world applications. That’s really where we can all see the true value of new solutions and concepts. We’re lucky enough to work with some leading organizations that want others to benefit from their experience and I’m happy to have the opportunity to share two of these applications with you. Protecting Educational Facilities UCF has adopted advancements in technology, particularly video surveillance solutions, to help ensure stronger security on campus Educational institutions face an increasingly complex risk environment. Recent high-profile incidents emphasize these risks and magnify the vulnerabilities that educational facilities face. These incidents have led to more public demand for improved security solutions across campuses. The primary mission of these organizations is to deliver quality education to students, and they face the challenge of balancing between a highly secure facility and one that supports open interaction. The University of Central Florida is no different. This organization, one of the largest universities in the country, has adopted advancements in technology, particularly video surveillance solutions, to help ensure stronger security on campus. Active Shooter Incidents In March 2013, UCF faced an active shooter situation in which a former student planned to pull the fire alarm in a residence hall and then attack his classmates as the building was evacuated. However, the shooter’s gun jammed, and as officers were closing in on the gunman, he took his own life. During the university’s response to the incident, accessibility to critical video data was a major issue. Educational institutions face an increasingly complex risk environment UCF had cameras in the area where the incident took place, but first responders had no way of viewing the footage without being at the physical location of the video recorder. At the time, UCF had a wide variety of standalone systems in place, including non-integrated video surveillance, access control and intrusion systems. As a result, there was no way to centralize video management, viewing and analysis. Upgrading From Analog Systems Altogether, its security system consisted of older analog platforms that were reaching end of life, 58 standalone servers, 12,000 access points and a wide variety of DVRs — all being managed in a siloed manner. UCF needed a solution that would allow officials to centralize system management, store video data more effectively and reliably, and enable the security team to deliver situational awareness to responders when needed. Security leaders sought a way to further modernize its security, surveillance, access control and IT infrastructure The university deployed an HCI solution, one that is optimized for demanding, data-intensive workloads like video surveillance. Using standard off-the-shelf server hardware, the system aggregates the storage and compute resources from multiple servers into a single unified pool that all cameras can access, which maximizes performance and storage capacity utilization. The platform also hosts the university’s video management solution, which serves as a centralized source to manage video and effectively protect its security data. Because of the growing demand for video across UCF's campuses — for both safety and business purposes — the HCI solution’s ability to eliminate the opportunity for data loss and easily scale were key components in its selection. Protecting Air Travel And Airports In 2012, Charleston International Airport embarked on an ambitious upgrade project dubbed the Terminal Redevelopment and Improvement Program. The $200 million initiative was designed to modernize and expand the facility to meet increased passenger demand. While the aesthetics and amenities of the airport were under construction, security leaders sought a way to further modernize its security, surveillance, access control and IT infrastructure. The IT and security teams needed to address the challenges of their existing standalone server environment, which included siloed systems, management complexity and high administrative and equipment costs. Charleston International Airport embarked on an ambitious upgrade project dubbed the Terminal Redevelopment and Improvement Program Considering the high value of the airport’s video, security and IT data, it required a solution that could deliver reliable data protection, system resiliency and fault tolerance. The airport is required to store video for 30 days, but it seeks to expand its retention time to 60 days. Therefore, technology that can scale simply was key in the selection process. Storage System Updates It also required a storage platform that could manage the demanding and write-intensive nature of its nearly 250 IP surveillance cameras — a challenging task for traditional video recorders. The airport deployed HCI appliances to better manage captured video data and expand its archive capability for video surveillance. Users rely on video to validate whether something did or did not happen - and this is essential in airports HCI surveillance solutions are designed to provide industry-leading resiliency. Even if multiple hardware failures occur, including an entire appliance, video management servers will remain online and recording, and any previously recorded video will continue to be protected and accessible. Reducing Expenses And Costs The solution also reduced total cost of operations by consolidating servers, storage and client workstations into one enterprise-class solution that is easily managed from a single user interface, without the need for specialized IT skills. These use cases demonstrate the value emerging technologies bring to these types of modern environments. And they show that solutions like HCI are no longer simply much-talked about technology trends. Video, IT and security data is critical to organizations of all types and they need to ensure their investment in capturing this data is protected. From a security standpoint, users rely on video to validate whether something did or did not happen. If that video data isn’t protected, they lose a very valuable investigative tool. That isn’t an option in today’s complex environment. That’s is why it is paramount to understand how new technologies can help expand current capabilities and evolve security operations. This can’t be left to chance.

Government Institutions Should Utilize VSaaS For An Integrated Video Surveillance System
Government Institutions Should Utilize VSaaS For An Integrated Video Surveillance System

Video surveillance as a service (VSaaS) is not just for commercial organisations. Federal, state and local governments can also realize benefits from the technology—and use it to deliver an integrated video surveillance system that addresses some of their unique security needs. Video Surveillance as a Service (VSaaS) What is VSaaS? Simply stated, it’s a cloud-based video surveillance solution that is packaged and delivered as a service over the internet. The price varies depending on the features of your plan (i.e. number of cameras, amount of storage, software features, etc.), and you pay a monthly subscription price to use it. How does it work? Internet Protocol (IP) cameras are installed at site locations, and the video is captured and streamed to a service provider’s data center via an internet connection. The video management software (VMS) runs on backend infrastructure provided by the service provider’s cloud. All video processing is done in the cloud, and all that is required to view the footage is an internet-connected device and a web browser. Retail, health care, education, and transportation all benefit from the flexibility and architecture of VSaas Growing VSaaS Providers Solution providers such as Axis Communications, Genetec, and G4S among many others offer VSaaS solutions, and the market is growing. According to IHS Markit, the market is expected to reach $2.3 billion in 2021. VSaaS is a solution with cross-industry appeal. Retail, health care, education, and transportation all benefit from the flexibility and architecture of the solution. But how does VSaaS address the surveillance needs of government institutions? Geographic Coverage And Access To protect cities and towns, law enforcement must watch over widespread geographic areas. Their work involves monitoring and policing many different neighborhoods, buildings, garages, parks, and walking paths—basically anywhere there is property or people to protect. They rely on video surveillance to help them keep these environments safe. But it’s more than local law enforcement officers who use video footage. From local city officials to federal and state law enforcement agencies, many other people, at times, need access to video footage captured by city surveillance cameras. Centralized Remote Monitoring How does VSaaS help? VSaaS enables the installation of cameras throughout cities and communities and stream footage to a central location via the Internet. Because the system is centralized, it eliminates the need to manage a lot of different standalone DVRs or NVRs, which enables organizations to monitor a large area from a remote command center. VSaaS enables the installation of cameras throughout cities and communities and stream footage to a central location via the Internet Plus, anyone with proper credentials can access the footage from an Internet-connected device—whether that be a smartphone, laptop, desktop, or tablet. That makes it easier for multiple agencies to work together, which in turn can improve communication and response time to incidents. Budget Concerns And Flexibility Tight budgets are normal in government. As a result, it’s often a challenge to procure capital for new technology purchases—and that sometimes leads to underfunded projects and difficulty upgrading old technology. VSaaS changes the expense model. It allows you to shift from a capital expenditure (CapEx) model, where large capital funding is required to purchase equipment, to an operational expenditure (OpEx) model, where the costs of the solution become an operating expense. Since the cameras, installation, storage, and software are packaged into a service, you don’t need a large capital outlay up front—you simply pay a predictable expense every month. VSaaS provides the capability for you to increase storage capacity when you need it Feature And Storage Capacity Upgrade Features VSaaS also makes it easier to upgrade old technology. When new technology becomes available, you can upgrade to it as part of the service. You no longer have to stick with old technology because of capital budget restrictions. Instead, you can upgrade to better cameras and management software features as they become available. The same is true for storage capacity. As camera resolution increases, the amount of data captured also increases. In addition, with the evolution of smart city technology and big data analytics, video data has become more valuable. As a result, there is a need not only to store more data but also to keep that data accessible for a longer period of time. VSaaS provides the capability for you to increase storage capacity when you need it. You can scale to accommodate growth, and since the storage is delivered as part of the service, you can leverage the “pay for use” model to manage your costs. On-Premise Storage Or Hybrid Where should surveillance video be stored? It’s an important question. After all, government entities must always comply with data privacy laws and handle data properly to ensure it can be used as evidence if needed. As a result, officials may prefer to be selective about where they store video data. In fact, the concern over regulatory requirements and security and privacy issues, according to Gartner, will lead governments to implement private cloud at twice the rate of public cloud through 2021. The provider’s ability to store large amounts of data cost-effectively makes VSaaS possible That’s not necessarily a show-stopper when it comes to video surveillance. Some VSaaS providers offer hybrid options. Plus, one of the things that makes VSaaS possible is the provider’s ability to store large amounts of data cost-effectively. Because service providers can manage their storage infrastructures economically, they can offer their service at an attractive price. Multi-Tier Storage Infrastructure In a way, government institutions (as well as commercial organizations) can do the same thing. If a government entity—for example, a small municipality—wanted to store their data on-premise or implement a hybrid configuration, they could solve some of their video storage challenges by implementing a multi-tier storage infrastructure similar to what a VSaaS provider might use to provide the actual service. A multi-tier storage infrastructure uses different storage media—disk, object storage, tape, and cloud—and combines them to deliver the total capacity needed while balancing performance and cost. The diagram below is an illustration of a multi-tier infrastructure: As the diagram shows, storage capacity grows using lower cost forms of media as volume and long-term retention requirements change. Files are moved between tiers based on user-defined policies. When the policies are met, the files are moved to a lower cost tier. Some file systems allow for multiple copies be written at ingest which not only minimizes the traffic of moving files across the network, but also provides much needed data protection through a second copy on a lower-cost tier. This scenario enables you to optimize the amount of high-performance media in your infrastructure and lower the long-term cost of retaining files. VSaaS offers many benefits for government institutions and commercial organizations alike Choice Of Implementations VSaaS offers many benefits for government institutions and commercial organizations alike. But not every implementation has the same needs or requirements. The good news is, when it comes to video surveillance solutions, you have options. You can leverage the benefits of VSaaS, in either a public cloud or hybrid scenario, depending on the service provider. Or if your needs dictate, you can achieve some of the same capacity and cost-saving benefits you would get from a VSaaS solution by implementing an on-premise solution based on a centralized VMS system and multi-tier storage. The choice is yours.
