28 Security Dealer & Integrator / September 2018 Mobile apps also considerably extend the security system user base. e contrast in lifecycle cost between cloud and on-premises sys- tems is very easily shown in a graph like Figure 1 (le), which shows a cloud TCO savings of 15 to 20 percent. In TCO cost comparisons that I have personally performed for clients, the cloud TCO savings can range between 10 and 40 percent – not including the costs of hot redundancy for process- ing, data and video storage, mobile device wide-area support and cyber- security costs, which of course are not part of the on-premises deployment. Any cloud vs. on-premises cost comparisons for decision-makers must include these important aspects that otherwise would not usually be part of the stakeholder thinking (except per- haps for IT stakeholders). Cost comparisons for security sys- tems whose servers reside in corpo- rate data centers must account for IT cost allocations, which for a server are typically 80 percent or more of the life- cycle costs. For the data center storage refresh cycle, the cost to decommission the upgraded storage must be consid- ered, which includes wiping the hard drives of sensitive data. Access control and video surveil- lance data contains protected personal information – particularly applicable under GDPR. is decommissioning cost factor is real but oen omitted in cloud solution TCO cost comparisons, as are some other cost factors. Security System TCO Cost Factors ere are eight security system TCO factors for an enterprise deployment where the IT department is hosting the servers in a corporate data center – as illustrated in Figure 2 (page 30), furnished by the Security Industry Association (SIA). e color legend in the donut graph shows the oen-found relative cost of corporate video system deployments. tain the integrity of video surveillance and store traffic video analytics. Remote access to video and to store analytics data is also important. e expense of hot redundancy for on-premises servers and video storage systems typically makes them cost-prohibitive; however, they are built into true cloud-based systems, as is secure wide-area and global remote access with multi-factor authentica- tion. e strong cybersecurity features of cloud deployments are typically not applied to on-premises systems – primarily for cost reasons. Cloud vs. On-Premises TCO With fully on-premises systems, there are typically two CapEx investment bumps – the initial investment, and the hardware refresh around the fourth year for hard drive replacement and computer processing power and mem- ory upgrades. e computer upgrades are typically desired for support of expanded soware functionality and increased application usage. ese days, mobile device usage continues to grow, with visitor man- agement systems and personnel safety applications being prime examples. Here are several key factors that should be under consideration: • Hot redundancy for system uptime (for video viewing and recording; alarm monitoring and response; and real-time server-based functionality – such as analytics, real-time access pol- icy enforcement, etc.); • Remote operator and responder access (access to data and control func- tions for security personnel on the ground); and • Redundancy for data storage (especially important for compliance with corporate and regulatory video retention requirements, integrity of investigations and historical analytics). e importance of any one factor will vary depending on the end-cus- tomer's type of business and the size and extent of business operations. For example, real-time hot redun- dancy for system processing and data storage elements is drastically different between on-premises and cloud-based systems. For a multi-site retail busi- ness, these factors are vital, because the video system requirements typ- ically include high video resolution and frame rate, 30-day or longer video retention, and high up-time to main- Figure 1: Example of a five-year TCO lifecycle comparison of cloud-based vs. on-premises systems.
