PoE (Power-over-Ethernet) dome cameras.

Running multiple cables to your security cameras can be a real pain. But you know what’s less of a pain? Running only one cable to each camera! How is that possible, you ask? It’s simple. Power over Ethernet.

What is Power over Ethernet? Power of Ethernet (or PoE) is the process of using wires already built into an Ethernet cable to run electricity in addition to network data. You can use PoE both to connect devices to your network and to power them up with just one Ethernet cable.

Throughout the rest of this post, we’ll talk about how PoE works and how to harness its power for security applications. We’ll also talk about the limitations of PoE, but more importantly, how to overcome those limitations.
