Smart Home & Low Voltage

Smart Home Electrical & Low Voltage Wiring in Fairfax, VA & Northern Virginia

Modern smart homes do not run on Wi-Fi alone — they run on properly installed electrical infrastructure that makes every device, network connection, and automation system work reliably. Rojas Electric installs the electrical backbone of smart Northern Virginia homes: hardwired ethernet networks, concealed TV wiring, smart switch systems, Wi-Fi access point wiring, and home automation electrical setups. We serve Fairfax, McLean, Vienna, Herndon, Reston, Great Falls, and all of Northern Virginia — the communities where smart home adoption in the DC metro area is highest.

We approach smart home electrical the same way we approach everything else: assess what you actually need, recommend the right solution, install it cleanly, and make sure you know how to use it before we leave. Whether you want to eliminate the cable mess behind your TV, wire your entire home for gigabit ethernet, or integrate your electrical system with a Span smart panel for full energy visibility, Rojas Electric handles the electrical side completely.

Smart Home & Low Voltage Services We Offer in Fairfax, VA & Northern Virginia

Data & Ethernet Wiring

Hardwired Cat6 and Cat6A ethernet runs from your router or network switch to every room that matters — home office, living room, bedroom, media room, and anywhere reliable wired network performance is needed. Hardwired ethernet is always faster and more reliable than Wi-Fi for devices that support it.

Wi-Fi Access Point Wiring

Professional Wi-Fi coverage throughout your home requires access points strategically placed and hardwired — not mesh nodes struggling to communicate wirelessly. We wire dedicated ethernet runs to access point locations and provide the electrical boxes and pass-through plates for a clean finished installation.

TV Mounting with Concealed Wiring

We mount your flat-screen TV and conceal all HDMI cables, power cords, and component connections inside the wall — no visible cables, no surface-mounted conduit. We also install a recessed power outlet behind the TV location so the power cord never shows.

Smart Switch Installation

Smart lighting switches compatible with Amazon Alexa, Google Home, and Apple HomeKit installed correctly — including assessing whether your existing wiring includes the neutral wire that most smart switches require.

Smart Lighting Control Systems

Multi-zone smart lighting control allowing different rooms to be controlled independently via app, voice, or schedule. We handle the electrical installation and help you configure the system through your preferred platform.

Home Automation Panel Installation

For comprehensive home automation systems, we install the electrical infrastructure required: dedicated circuits for control panels, low-voltage wiring for sensors and controllers, and coordination with your automation system installer.

Structured Cabling Installation

A structured cabling system organizes all your home's data, coaxial, and audio/video cabling into a central distribution panel — making adds, changes, and troubleshooting straightforward for the life of the home.

Security Camera Wiring

Power and data wiring for hardwired security cameras — including PoE (Power over Ethernet) camera systems that run on a single Cat6 cable per camera. More reliable than wireless and not dependent on battery life.

Doorbell Camera Installation

Wired doorbell camera installation including voltage assessment of existing doorbell wiring and transformer upgrade if needed to power modern smart doorbell cameras.

Our Smart Home Installation Process in Fairfax, VA & Northern Virginia

1

Needs Assessment

We start by understanding what you want your smart home to do — which rooms need wired ethernet, where access points should go, whether TV wiring needs to be concealed, and which smart home platform you are using.

2

Cable Routing Plan

We plan all cable routes before any walls are opened — maximizing the use of existing pathways such as attics, crawlspaces, and wall cavities to minimize drywall impact on finished spaces.

3

Clean Installation

We run all cables through walls and ceilings with concealed routing, install proper low-voltage mounting brackets and wall plates at every termination, and label all cables clearly.

4

Testing

Every ethernet run is tested with a cable tester before wall plates are installed. Every smart switch is paired with your smart home hub and verified functional before we leave.

5

Walkthrough

We walk you through every system we installed.

For computers, smart TVs, gaming consoles, and streaming devices, hardwired ethernet delivers faster speeds, lower latency, and zero interference — eliminating the buffering and connection drops that Wi-Fi networks in dense Northern Virginia neighborhoods are prone to.
A flat-screen TV mounted on the wall with visible cables trailing to the floor looks unfinished. A properly installed in-wall TV wiring system looks like it was built that way — clean, intentional, and permanent.
Smart bulbs will not work if the wall switch is turned off. Smart switches turn any connected lights into app and voice-controlled lights without changing a single bulb.
Paired with a Span smart panel, a smart home electrical system gives you complete visibility into both your home's energy flows and your lighting and device control — managed from a single smartphone interface.
Proper structured cabling and hardwired ethernet infrastructure supports whatever smart home technology comes next. Wireless protocols change. Ethernet lasts decades.

Benefits of Rojas Electric for Commercial Projects in Fairfax, VA & Northern Virginia

FAQs:

Commercial Electrical Services in Fairfax, VA & Northern Virginia

Ethernet wiring installation in Fairfax and Northern Virginia typically runs $150 to $350 per run depending on run length, accessibility, and wall plate type. A whole-home ethernet project covering 5 to 8 rooms with a central patch panel runs $1,500 to $4,000. We provide free estimates based on your specific home and layout.

Yes. In-wall TV cable concealment is permitted and very common in Northern Virginia homes. All power cabling run inside walls must use either a listed in-wall power kit with UL-rated cable, or a separate recessed outlet installed behind the TV location by a licensed electrician. Rojas Electric installs the recessed power outlet and the in-wall cable pathway for a completely clean installation.

We install Lutron Caseta, Leviton Decora Smart, Kasa, GE Enbrighten, and other major smart switch brands depending on your smart home platform and wiring configuration. Lutron Caseta is our most-recommended brand for reliability and Apple HomeKit compatibility — and it works without a neutral wire, making it compatible with older Northern Virginia homes.

Most smart switches require a neutral wire in the switch box. Homes built before approximately 1985 in Northern Virginia often do not have neutral wires in switch boxes. Before installing any smart switch, we check for neutral wire availability. When neutral wires are absent, we recommend Lutron Caseta smart switches.

Proper Wi-Fi coverage requires access points hardwired via ethernet to a central network switch — not mesh nodes communicating wirelessly. We run Cat6 ethernet from your equipment location to each access point mounting location, install low-voltage brackets and wall plates, and leave the access point mounting and network configuration to your IT provider or preferred network company.

Yes. We install PoE (Power over Ethernet) camera wiring — a single Cat6 cable per camera that carries both power and video signal. We route cable from each camera location to your NVR or PoE switch location cleanly through walls and attic space.

A whole-home ethernet installation covering 5 to 8 rooms with a central patch panel typically takes 1 to 2 days depending on home size, ceiling accessibility, and the number of runs. We give you a specific timeline during your estimate.

Yes. We use attic and crawlspace access, existing wall cavities, and low-profile techniques to run cables with minimal drywall impact in finished homes. The finished result looks intentional — wall plates, properly terminated ends, and labeled runs at the distribution point.

Structured cabling consolidates all your home's data, coax, and audio/video cabling in a single central panel — making it easy to change what connects where and troubleshoot problems. It is most valuable in new construction and major renovations, but can be retrofitted into existing homes.

Yes. Smart home electrical is particularly popular in the Herndon, Reston, McLean, and Great Falls corridors of Northern Virginia. We install ethernet wiring, TV mounting, smart switches, and security camera wiring throughout all of these communities and across Northern Virginia.
