Structured Wiring and Smart Home Basics: Getting Your House Ready

Working from home, streaming in every room, security cameras, smart thermostats and video doorbells all depend on a network that Wi-Fi alone often can’t deliver across a whole house, especially in brick and plaster homes or long ranch layouts. Structured wiring is the low-voltage backbone that makes it all reliable.

What Structured Wiring Is

Structured wiring is a planned set of low-voltage cables run to the rooms where you’ll need them, all home-running to one central location:

• Network cable (Cat 6 or better) for computers, TVs, game consoles and wireless access points
• Coaxial cable where cable TV or satellite is still used
• Cable for cameras, doorbells and sensors, often powered over the network cable itself (PoE)
• A central panel where your modem, router, switch and patching live, ideally with a dedicated power circuit and surge protection

Wired Beats Wireless, Where It Counts

Wi-Fi is convenient, but walls, floors and neighbors’ networks all slow it down. A wired connection is faster and steadier for a home office, streaming TV and gaming. The best whole-home Wi-Fi uses wired access points, ceiling-mounted units connected back to the network by cable, rather than mesh units passing the signal wirelessly from one to the next.

Smart Home Wiring

• Smart switches and dimmers: many need a neutral wire in the switch box, which older homes often lack. We check before you buy.
• Video doorbells: most need a proper low-voltage transformer, not just batteries.
• Cameras: wired PoE cameras are more reliable than battery cameras and don’t need recharging.
• Smart thermostats: many need a “C” (common) wire from the HVAC system.
• Whole-home audio and outdoor speakers: planned speaker cable runs.

The Best Time to Wire: Before the Walls Close

New construction and remodels are the cheapest time to run low-voltage cable. If you’re building, finishing a basement or remodeling, have us run network cable to every room you might want it in, plus a spare conduit from the network panel to the attic or crawlspace so future cables can be pulled without opening walls. For existing homes, we fish cable through walls with minimal openings.

Doing It Right

• Keep low-voltage cable separated from power wiring, as the code requires, to avoid interference and hazards.
• Terminate and label every run, then test it.
• Put the network panel on its own circuit with surge protection. See whole-home surge protection.
• Plan ventilation for the equipment closet; routers and switches give off heat.

Frequently Asked Questions

Is it worth running ethernet in a house?

For home offices, TVs and wired access points, yes. Wired connections are faster and more reliable, and they make whole-home Wi-Fi much better.

Can you run network cable in an existing house?

Yes. We fish cable through walls, attics and crawlspaces with small access holes and plan routes to keep patching to a minimum.

Why does my smart switch need a neutral?

Smart switches need a little power all the time to stay connected. Many older switch boxes don’t have a neutral wire; we can check and add one where needed.

Cat 6 or Cat 6A?

Cat 6 handles most home needs today. Cat 6A gives more headroom for future speeds over longer runs. We’ll recommend based on your plans.
