Video surveillance as a service (VSaaS) is not just for commercial organisations. Federal, state and local governments can also realise 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.

Centralised 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 centralised, it eliminates the need to manage a lot of different standalone DVRs or NVRs, which enables organisations to monitor a large area from a remote command center.

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.

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 organisations) 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 minimises 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 optimise 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 organisations alike

Choice of implementations

VSaaS offers many benefits for government institutions and commercial organisations 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 centralised VMS system and multi-tier storage. The choice is yours.
