Pre-wiring security cameras and alarm systems during construction costs $500–$1,500. Retrofitting the same infrastructure after drywall costs $1,500–$4,000+. The difference is access — when walls are open, running cable takes an hour. When they’re closed, it takes a day and leaves patch marks.
What to Pre-Wire in a New Arizona Home
Security Cameras (Exterior)
Every exterior camera location needs a single Cat6 cable run back to a central wiring closet or utility room. Standard locations for Arizona homes:
- Front door / entry (1 camera)
- Driveway facing the street (1 camera)
- Rear yard / back door (1–2 cameras)
- Side yards, especially any gate access (1–2 cameras)
- RV gate or detached garage (if applicable)
Plan for where you might want cameras even if you don’t install them right away. The cable is cheap. The drywall repair later isn’t.
Alarm System Sensors
If you want a hardwired alarm system, every door and window location needs a 2-conductor wire run back to the panel location. The rough-in stage is the only cost-effective time to do this — retrofitting means fishing wire through insulated walls or around drywall.
Standard alarm pre-wire includes:
- All exterior doors
- All ground-floor windows
- Garage entry door
- Siren location (interior, high on a wall)
- Keypad location (usually inside entry)
- Motion detector locations (living areas)
Structured Wiring (Cat6 / Ethernet)
While you have the walls open, run Cat6 to every room. WiFi has improved but hardwired ethernet is still faster, more reliable, and essential for home offices, gaming setups, smart TVs, and security cameras. Run more ports than you think you need — they’re cheap now and impossible to add easily later.
In-Wall TV / AV Locations
For every wall-mounted TV location, run at minimum an HDMI conduit and a power outlet position inside the wall. Add speaker wiring for surround sound. Add conduit for any future cable management. Plan these with your furniture layout, not your current TV size.
In-Ceiling Speaker Locations
If you want whole-home audio or in-ceiling speakers in any room, the rough-in stage is when to wire them. The actual speakers and amplifiers can be installed anytime, but the wire has to go in the ceiling before it’s drywalled.
When to Schedule Pre-Wire
There are two windows for pre-wire during new construction:
Rough-In (Best)
After framing is complete, before insulation and drywall. This is the ideal time. Every stud bay is open, you can route cable cleanly through interior walls, and the work goes fast. ZonaShield schedules around your framing and MEP (mechanical, electrical, plumbing) timeline.
Trim-Out
After drywall, before paint. Cable can still be fished through some locations, but it’s more difficult and some locations may require small access holes that need patching. More expensive and less clean than rough-in, but still much cheaper than post-occupancy retrofit.
What New Construction Pre-Wire Costs in Arizona
| Scope | Rough-In Cost | Post-Drywall Retrofit |
|---|---|---|
| Security camera locations (4–6) | $300–$600 | $800–$1,500 |
| Alarm system pre-wire | $400–$800 | $1,000–$2,500 |
| Cat6 structured wiring (8–12 drops) | $500–$900 | $1,500–$3,000 |
| In-wall AV / speaker wiring | $200–$500 | $600–$1,500 |
| Full package (cameras + alarm + Cat6 + AV) | $1,200–$2,500 | $4,000–$8,000+ |
Trim-out equipment install (cameras, panel, NVR, speakers) is a separate scope from pre-wire. Pre-wire is infrastructure only — cable and boxes.
Common Pre-Wire Mistakes to Avoid
Planning Camera Locations Without Walking the Property
Don’t mark camera locations off a blueprint without standing on the lot. Sight lines, landscaping, and neighboring structures change what’s useful. Walk the property with your builder and a ZonaShield tech before rough-in if possible.
Wiring Only What You Need Right Now
Pre-wire for what you might want in 5 years, not just what you’re buying at move-in. Extra drops and extra camera locations cost very little now. They cost a lot later.
Forgetting the Wiring Closet Location
All your cables need to terminate somewhere — a structured wiring panel or utility closet. If your builder doesn’t plan this in advance, you end up with cables terminating in a hall closet or the garage. Plan the termination location before rough-in starts.
Skipping Conduit
Where possible, run conduit inside walls at TV and camera locations so future upgrades don’t require opening walls. Even a short conduit sleeve makes replacing or adding cable later a 5-minute job instead of a half-day project.

Do I need to choose my cameras and alarm system before pre-wire?
No. Pre-wire just installs the cable infrastructure. You choose the specific cameras, alarm panel, and smart home equipment at trim-out or later. The cable gives you options without committing to specific products today.
Can you work with my builder?
Yes. ZonaShield coordinates with builders and general contractors. We schedule around framing and MEP stages and work within the construction timeline.
What if I miss the rough-in window?
We can still pre-wire at trim-out for many locations, and do a clean retrofit after move-in. It costs more and takes longer, but it’s not impossible. Call us wherever you are in the build and we’ll tell you what’s still feasible.
Do you pre-wire in all Phoenix Valley cities?
Yes — Peoria, Surprise, Queen Creek, Gilbert, Chandler, Mesa, Scottsdale, Glendale, and all surrounding areas. We follow construction schedules throughout the Valley.
