Low-Voltage Wiring in Nassau County, NY
All Done Electric Works installs low-voltage wiring for Nassau County homes and businesses: network and data cable, speaker wire, video doorbells, security cameras and intercoms. We have been doing electrical work for 15 years, and we respond within 1 hour. Low-voltage jobs look simple from the outside, but New York treats some of them as regulated security work, so we explain which rules apply before we pull a single cable.
Recessed (hi-hat) lighting in Nassau houses
Low-voltage wiring carries signals and small amounts of power, not the 120 or 240 volts that run your outlets and appliances. Most of it sits at 50 volts or less. In a typical Nassau house that means:
The wire is lighter, but the jobs still need planning. Cable routed beside a 120-volt line can pick up noise, and a hole drilled through a fire block or a joist has to be sealed or placed correctly. Those details are why an electrician is a sensible person to run this cable.
Cameras, video doorbells and intercoms
A camera is only as good as its view and its wiring. Before mounting anything we walk the property with you and ask what you want to see: the driveway, the side gate, the back door, a delivery spot. Then we choose positions that cover it without staring into a neighbor’s window.
- Wired cameras: one cable carries both data and power, which makes the picture steadier than Wi-Fi and keeps working if your router hiccups.
- Video doorbells: many need a transformer rated for the unit. An old doorbell transformer is often too weak, and we replace it when it is.
- Intercoms and door entry: for two-family homes, offices and shops, we install and wire door stations and the units inside.
- Recording: we set up local recorders or cloud accounts, and we show you how to view footage from your phone.
Home audio and entertainment wiring
Ceiling speakers, outdoor patio audio and a TV with hidden cables all begin with a plan for where the wire goes. We run speaker cable and in-wall rated cable, set volume controls where you will actually reach them, and keep audio runs away from noisy electrical lines. For wall-mounted TVs we can bring power and signal behind the wall to one clean location, with a code-compliant outlet and no extension cord dangling.
Questions about low-voltage wiring
We do. The permit rules differ there: under-50-volt work is generally exempt, but fire alarm work is not, and we confirm which applies to your building.
Often, yes. We use attics, basements, closets and exterior routes to avoid opening more drywall than necessary, and we patch what we open.
It depends on the town or village. Many data and audio runs do not need one, while fire alarm work usually does. We confirm with your municipality before starting.
It means running cables before the walls are closed, so Ethernet, speaker and camera cable is already in place when drywall goes up. It costs less than cutting walls later.
Yes. We check the transformer and wiring first, because a weak old doorbell transformer is the usual reason a new unit misbehaves.
Installing security and fire alarm systems requires a New York Department of State installer license, and camera or entry systems used for detection can fall under it. We hold that license, so we can install your cameras and intercoms.
It is cabling that carries signals or low power, usually 50 volts or less. Ethernet, speaker wire, doorbells, thermostats and many camera systems are examples.
