When deploying video surveillance, one of the first questions typically considered by the end user is whether to go with the on-premises (NVR) or cloud (VSaaS) architecture. To choose which one to deploy, an understanding of the pros and cons of each is required.

An NVR setup also has drawbacks. For starters, the cost of purchasing the on-premises equipment can be prohibitive for certain users. “You’re looking at a much higher initial capital expenditure to deploy your system, and it involves more people and more time to install, configure and maintain. It is therefore a larger commitment and higher upfront cost,” Chowdhury said.

“The initial investment needed could outprice smaller companies. These organizations must also consider the knowledge and talent within the business, as solution maintenance and trouble-shooting must be done in-house,” Javelle said.

Security is also a major issue with an NVR setup. “There are three concerns with NVRs – theft, damage and recording breakdowns. When a business is burglarized, chances are the NVR is often stolen. And if there's a fire, the recording device is often too damaged to be useful in determining whether it was set purposely and if so, who was the perpetrator,” said R. Nandakumar, Founder of ATSS.

“NVR(s) can be subject to insider threats. In addition, a cyber breach of a company’s network could also contribute to a loss of recording and management, and the extraordinary costs of recovery and replacement,” said Chris Grniet, Regional VP for Security and Technology Consulting at Guidepost Solutions.

Finally, the NVR architecture gives the user less flexibility to add or reduce cameras, and simultaneous viewing and access to footage tend to constrain the system. “In an NVR setup, only a limited number of cameras can be connected. Performance is poor in general, especially when multiple users are attempting to use it at the same time; only a limited number of simultaneous viewers is allowed,” said Viachaslau Hrytsevich, Founder and CEO of 3dEYE.

The disadvantages of the NVR architecture, then, bring out the benefits of VSaaS, which typically requires only the cameras as well as a network switch or router to forward the video to the Internet. As such, the initial cost of setting up video surveillance is much reduced.

“There’s minimal hardware use, and VSaaS shifts the user to a predictable variable cost model, helping organizations leverage the solution’s cost efficiency to deliver better results,” said Keven Marier, Director ofr Technology Business Development at Milestone Systems.

“There’s low or no installation and deployment cost, which typically means very low capital expenditure with higher ROI. Any enterprise or organization can set up the surveillance system without buying costly hardware. They would just need to connect the IP cameras to the VSaaS cloud applications, and the cost of storage would also be low compared to any NVR/DVR systems,” said Ritesh Gupta, CTO of Product Engineering Services at Happiest Minds Technologies
