Summary
The outlet is never where you need it. It’s not up in the ceiling where an access point should sit. It’s not behind the wall panel you want to mount flush, or out under the eave where a camera would watch the driveway. Running a new circuit to any of those spots means an electrician, drywall repair, or both. There’s a cleaner route.
A single network cable can carry data and electricity at once, a setup called Power over Ethernet, and it pushes far more wattage than most people expect. In my own house, the access points and smart panels run on nothing but a Cat6 line. Here are five gadgets worth wiring the same way.
Wireless access points
One cable to the ceiling, no outlet required
A ceiling is the right place for an access point and the worst place for a receptacle. Four UniFi access points sit flush against my drywall, and not one has an outlet behind it. Each runs back to the network rack on a single Cat6 line, and the switch at the far end sends power and the network signal down that same wire. The AP clicks into its mount.
Coverage is the reason to bother. A router shoved in a closet leaves dead zones at the end of the house, while a few ceiling points blanket every room. Skipping the outlet is what keeps the install clean. If you run the cable yourself, use the right grade for the job, because a long PoE run acts like a small power line and thin conductors get hot. I use Ubiquiti UniFi access points, but there are plenty of PoE options.
A wall-mounted smart home control panel
The win is hiding the outlet, not faster Wi-Fi
A portable speaker is fine on Wi-Fi. A panel you mount flush in the wall is a different problem, because the outlet and cable behind it are exactly what ruin the look. I put three Echo Hubs in during a basement build, each sitting flat against the drywall with nothing visible around it. A small converter behind every panel splits the PoE feed into USB-C power and a wired network drop, which is why I took on the extra work mid-construction instead of cutting in receptacles.
This isn’t about bandwidth. A control panel sips data. What PoE buys you is a fixed mount with no wall wart, no exposed cable, and no battery to recharge. It stays powered and answers the instant you step up. An Amazon Echo Hub plus a PoE-to-USB-C adapter makes the whole thing disappear into the wall.
Security cameras
A fixed camera never moves, so wire it once
This is the use PoE is known for, and for good reason. A camera bolts to one spot and stays there for years, which makes a permanent cable the obvious call. One line carries the video and the power, so there’s no outlet to add under the eave and no battery to climb up and swap. The feed holds a steady connection instead of stuttering when the Wi-Fi upstairs gets busy.
I don’t run a PoE camera yet. It’s the one drop I haven’t filled, though the rack has spare ports and the wire path already sits in the wall, so it comes down to pulling cable. When you wire one, the cable matters more than the camera itself. Cheap copper-clad spools cause the exact dropouts people blame on the hardware. A Reolink PoE camera is an easy starting point.
A VoIP desk phone
Offices have run phones on network cable for decades
The desk phone was doing this long before smart home gear existed. Office buildings have powered VoIP handsets off the network jack for two decades, one cable handling both the call and the electricity. Work from home, and the same trick clears space on your desk. A phone that draws power from its Ethernet line needs no separate adapter crowding the power strip.
A VoIP handset pulls only a few watts, so almost any PoE switch or injector feeds it with room to spare. Plug the cable into the back and it boots, registers, and stays connected the whole call, with no wireless interference to drop it. For a home office already wired for internet, a PoE desk phone turns one existing jack into both a line and a power source.
A Raspberry Pi or mini home server
One wire powers the little machine running your network
A Raspberry Pi is perfect for the always-on jobs, like blocking ads network-wide with Pi-hole or running Home Assistant as the hub of your smart home. The snag is that a closet or basement shelf rarely has a spare outlet, and a wall charger there looks like an afterthought. The official Raspberry Pi PoE+ HAT fixes it. The board snaps onto a Pi 4 or Pi 5 and draws both power and network from one cable, so the machine runs on a single line with no adapter in sight.
That frees a home server to live wherever it makes sense rather than wherever a plug sits. A closet, an attic, a corner of the utility room: any spot with a network drop is fair game. Pair a Raspberry Pi with the matching PoE HAT for a self-contained server fed entirely by Ethernet.

Power and data ride the same line, so a device can go where it actually belongs instead of where a plug happens to be. Cable is cheap, far cheaper than paying an electrician to run a new circuit. Any spare drop you leave in a wall now becomes a mounting spot later. Next time you’re fishing a line to one stubborn corner, pull a second while you’re in there.
