Network Switches & PoE — When You Need Them and Which to Buy
Your router has 3-5 Ethernet ports. That's not enough for a modern smart home. Here's the switch you actually need, when PoE matters, and the install pattern that ages 10 years.
Why a switch matters in 2026
Your router has 3-5 Ethernet ports. That covers a TV, a streaming box, a game console, and maybe a NAS. If you want to wire in a Sonos system, security cameras, a home office computer, a Lutron hub, smart shade hubs, and access points — you need a switch. The switch is what turns "I have a router" into "I have a network."
PoE — Power over Ethernet, the underrated trick
PoE sends power AND data over the same Ethernet cable. It's the cleanest way to power security cameras, wireless access points, VoIP phones, and now LED lighting controllers. Instead of running an Ethernet AND a power cable to a ceiling-mounted access point or doorbell camera, you run one Cat6 cable and it carries both. The switch on the other end supplies the power.
If you're putting a wireless access point in the ceiling, a Wyze cam in the eaves, or a Ring camera at the gate, PoE is the install that makes it look professional.
The three switch tiers
Tier 1 — Unmanaged switches (under $50)
The simplest. Plug in cables, lights blink, traffic flows. No configuration. Good for adding ports behind a TV stand or in a media closet. Most homes need at least one.
TP-Link 8-port Gigabit (TL-SG108)
Cheap, reliable, fanless. The default 8-port unmanaged switch. Works behind any TV stand or media console.
Check on Amazon →Netgear 16-port Gigabit (GS316)
16 ports. Metal case. The "I'm running my whole house through this" unmanaged switch.
Check on Amazon →Tier 2 — Managed PoE+ switches ($100-$300)
Adds PoE+ output (30W per port) for powering access points and cameras, plus a web management interface for VLANs, QoS, and link aggregation. The right call for any home with multiple ceiling access points or a security camera install.
TP-Link Omada 8-port PoE+ (TL-SG2210MP)
8 PoE+ ports, 130W power budget. Pairs with TP-Link Omada APs for a managed network without UniFi complexity.
Check on Amazon →Ubiquiti UniFi Switch Lite 8 PoE
8 ports, 4 PoE+. Pairs with UniFi APs in the UniFi Controller. The cleanest UniFi-managed switch under $200.
Check on Amazon →Tier 3 — Pro / multi-gig + PoE++ ($400+)
For homes running multi-gig fiber, 10G backbone to a server, or 802.3bt PoE++ (60-90W per port) for high-power devices. Most homes don't need this. Some absolutely do.
Ubiquiti UniFi USW-Enterprise-24-PoE
24 ports, all 2.5 Gbps with PoE++. Two 10 Gbps SFP+ uplinks. The "I take my network seriously" switch.
Check on Amazon →The "do I actually need PoE?" decision
You need PoE if any of these apply:
- You're mounting wireless access points in the ceiling (UniFi U6 Pro, TP-Link EAP670)
- You have or plan to add wired security cameras (Reolink, Amcrest, Ubiquiti UVC)
- You run VoIP phones (most business phones are PoE-powered)
- You have or plan to add PoE doorbells (Reolink doorbell, UniFi G4 Doorbell Pro)
You don't need PoE if you're only powering devices that already have wall warts (Eero mesh nodes, NAS, TVs, game consoles). Save the money and buy a regular unmanaged switch.
★ Rick's install pattern
Standard residential network rack for a $1M+ home: 1 Ubiquiti UDM Pro (router + controller, $400) + 1 UniFi 24-port PoE switch (~$800) + 3-5 UniFi U6 or U7 access points ceiling-mounted ($200-300 each). Total: $2,500-4,000 hardware + 8-12 hours labor for a clean install. That's a 10-year network. Mesh is fine for retrofit, but if we're pulling cable for new construction, this is what we install.
