The single most expensive mistake in a low-voltage scope isn’t a bad product choice — it’s a wiring decision made after the walls are closed. Once drywall goes up, every additional cable run means cutting into finished surfaces, patching, and repainting. Before framing, the same run is a five-minute job.
That timing gap is why pre-wire planning belongs in the same conversation as electrical rough-in, not as an afterthought once the homeowner asks about a security system during trim-out.
The runs that are cheap now and expensive later
Structured cabling to every TV location and home office. Wi-Fi is convenient, but it’s not a substitute for a wired connection at locations where a dropped signal is actually disruptive — a home theater, a home office, a media room. Cat6 (or better) to these points costs almost nothing during rough-in and becomes a real project once the wall is finished.
A dedicated low-voltage panel location. Every wired device — cameras, access points, a video doorbell system, whole-home audio — eventually routes back to a central point. Deciding where that panel lives before framing means it ends up somewhere sensible (a closet, a utility room) instead of wherever there happened to be room left after everything else was placed.
Camera and access control conduit. Even if a security system isn’t part of the initial build, running conduit to likely camera locations — entries, driveway, backyard sightlines — during framing means the system can be added later without exposed wiring or wall damage. Conduit is inexpensive; retrofitting a finished exterior wall is not.
Speaker wire for whole-home audio, even if the system comes later. The wire itself is a minor cost. The labor to fish it through finished walls after the fact is not.
What we actually need from the builder
The earlier we’re in the conversation, the better the outcome — ideally before the electrical rough-in walkthrough, so low-voltage runs can be coordinated with the electrician rather than fought around afterward. What we need at that point is simple: floor plans, a sense of how the homeowner (or target buyer, for spec builds) is likely to use each room, and rough locations for the electrical panel and internet entry point.
From there we plan the low-voltage panel location, camera and access-point conduit runs, TV and office cabling, and speaker wire — coordinated with the electrical trade so nothing gets fought over floor space or timeline.
The alternative
The alternative is what usually happens without a plan: a homeowner moves in, wants a security camera at the front door, and finds out the only way to get power and data there is exposed conduit run along a finished wall, or a wireless workaround that ages out of use within a year. Both are avoidable with a conversation that costs nothing and takes twenty minutes, at the point when it still matters — before the walls close.
If you’re a builder or GC with a project approaching electrical rough-in, that’s the window to loop us in.
