Power over Ethernet (PoE) is a revolutionary technology powering critical technology that keeps people and buildings safe. Over the last few years, PoE has become the go-to-choice for a host of networked devices, including IP security cameras, IP phones, and wireless access points. What makes it so popular is its ability to provide both data and DC power to devices through a single Ethernet cable.
The "plug-and-play" nature of PoE makes installation of remote equipment easy because it does not require any additional power cabling. This enables installers to place equipment in remote locations, away from any service panel or other power source.
Power surges can harm PoE systems
However, PoE devices are just as vulnerable to the effects of power surges as any other type of electrical equipment. With PoE so commonplace, plenty of vendors can provide equipment necessary to install PoE-based networks. However, how many of them are experts in surge protection? Here's why that's important.
While it's common knowledge that lighting strikes can cause a momentary—but dangerous— surge in voltage, weather is only responsible for a small percentage of actual surge events. Most are the result of technology, including fluctuations in local electrical grids or powerful motors found in HVAC equipment or heavy machinery cycling on or off inside a building.
