Smart Buildings: 5 Common Myths of Power-over-Ethernet Debunked

March 1, 2022



Power over Ethernet is most commonly known for powering VoIP phones and IP security cameras, but PoE technology can power and transmit data for an entire building. The technology has been in place for many years and is rapidly expanding its capabilities to power a multitude of devices in office spaces, hotels, schools, and hospitals, just to name a few. Despite the myths circulating that PoE is not reliable and doesn’t meet regulations, PoE is an incredibly viable option for powering your next smart building project. We’re debunking five of the most common PoE myths, and five of the biggest concerns businesses have when considering PoE as the infrastructure that powers an IoT smart building platform.

Myth 1: PoE is Not Reliable

One of the biggest objections when it comes to enabling a building with PoE is that it is not a reliable technology. The truth is, Power-over-Ethernet is an incredibly reliable technology for a variety of reasons. PoE technology relies on Ethernet, so it’s simply a new take on a vetted technology. Managing Ethernet is native IT, which means any local IT team can install and troubleshoot PoE. PoE is a wired technology with limited interference and enhanced security features. While the technology does rely on a direct wired connection, that doesn’t make Power-over-Ethernet any less flexible than comparable wireless technologies. Especially with an open API, companies have the ability to develop innovative use cases for PoE.

Myth 2: You Can’t Outfit a Building with PoE

It is possible to outfit an entire building with PoE. In fact, Power-over-Ethernet is revolutionizing smart buildings. While VoIP phones and IP security cameras were just the start of PoE, the technology now enables countless more devices. PoE can be used for human-centric lighting, occupancy sensors, asset tracking, security cameras, access control and more. Most manufacturer’s LED lights will work seamlessly with an open platform. The most valuable feature of PoE is that all these systems communicate directly through the same protocol. On top of being compatible with various devices, a PoE platform can also include application partners which allow for more flexibility of your PoE ecosystem. Relying on these trusted partners can expand the integration possibilities with PoE and lead to an even smarter, more reliable space.

Myth 3: PoE Doesn’t Meet Regulations

Power over Ethernet technology meets energy efficiency, emergency lighting and fire safety regulations including ASHRAE 90.1, Title 24, IEEE standards, NFPA NEC, and UL924. PoE power also goes beyond traditional standards to help building owners and developers reach their green goals. Using a PoE system can allow organizations to take advantage of sustainability credits including LEED and WELL which can lead to project savings and strong reputation in the construction market.

Myth 4: Power over Ethernet Technology Won’t Last

Ethernet has been around since 1973, in those 45 years, the applications of Ethernet have continued to grow. There is no reason to expect that will change. As mentioned above, Ethernet greatly reduces interference when compared to a typical wireless IoT system. PoE makes it simple to expand the network with more devices and is easily adaptable to use for a variety of devices including but not limited to:

  • LED lights
  • Access points
  • Cameras
  • VoIP
  • HVAC systems
  • Occupancy sensors

An IoT platform that is AI ready can turn a building’s IoT data into actionable insights. The machine learning algorithm helps building managers identify inefficiencies and determine if the wrong data is being collected, the wrong tools are being used or the wrong people are in place to handle the data. Armed with this data, building operators can make better data-driven decisions that save on costs and improve operational efficiency.

Myth 5: PoE Technology Only Controls Lights

An IoT platform powered by PoE can offer much more than smart lighting technology, it can be a hardware, software and analytics solution.


A node acts as an IoT hub by receiving power and data from the network switch and passing it to connected devices. As devices are connected, the network automatically discovers them for easy plug-and-play functionality.

Software and Analytics

Once devices are discovered, the user interface, accessible on any smart device, makes it easy to manage an entire IoT ecosystem. With each PoE device powered (and collecting data) via Ethernet the sheer amount of incoming data can become overwhelming. But previously independent systems can now communicate, and buildings can become more efficient with a software gateway.

PoE is a Realistic IoT Option for your Building Project

Power-over-Ethernet has been the target of many misleading statements, but in reality, PoE is a reliable IoT solution which meets regulations and has many capabilities beyond lighting. A PoE solution enables businesses to innovate by providing more actionable data. With hardware, software and analytics working together, PoE is not only attainable for your next building project, but a smart choice for future proofing your client’s building.
