A professionally installed wired home alarm system in Arizona costs $800–$2,500. Most standard residential jobs land at $1,000–$1,800. Monitoring contracts are optional — not required.

Monitoring Contracts — Do You Actually Need One?
This is where national alarm companies make their money. They discount the hardware to get you on a 2–3 year monitoring contract at $30–$60 per month. Over three years, that’s $1,080–$2,160 in recurring fees on top of the install price.
ZonaShield installs alarm systems without requiring a monitoring contract. You have three options after we install:
- Self-monitor — App alerts go straight to your phone. You decide how to respond. Free.
- Third-party monitoring — Companies like Alarm.com or Scout can monitor ZonaShield-installed systems for $10–$25/month. No long-term contracts required.
- Traditional monitoring — If you want a call center to dispatch police, you can add that to most systems. Usually $20–$50/month.
Bottom line: You don’t need a monitoring contract for an alarm system to work. The siren goes off regardless of whether you pay monthly. Most break-ins are deterred by the alarm itself — not the 4-minute police response time.
Wired vs. Wireless Alarm Systems in Arizona
For Phoenix-area homes, wired systems have clear advantages:
- No battery changes — Wireless sensors need battery replacements every 1–3 years. Multiply that by 20 sensors and it gets old fast.
- No signal dropout — Wireless systems can have interference issues. Wired doesn’t.
- Arizona heat — Wireless sensors mounted in exterior walls or attic spaces degrade faster in 115°F heat. Hardwired components run cooler.
- Harder to defeat — Sophisticated burglars know how to jam wireless signals. Wired systems don’t have that vulnerability.
The tradeoff is install time and cost. Wired systems take longer to install and cost more upfront. For renters or situations where you can’t run wire, wireless makes sense. For owned homes, wired is the better long-term investment.
New Construction Alarm Pre-Wire in Arizona
Pre-wiring alarm systems during new construction is significantly cheaper than retrofitting after drywall. While walls are open, ZonaShield can run all sensor and camera wiring for a fraction of the retrofit cost.
| Stage | Pre-Wire Cost | Retrofit Cost |
|---|---|---|
| Before drywall | $500–$1,200 | N/A |
| After drywall (retrofit) | N/A | Add $400–$1,000+ for access |
If you’re building in Peoria, Surprise, Queen Creek, or anywhere in the Valley, reach out before they close the walls.

Does ZonaShield require a monitoring contract?
No. We install the hardware, configure everything, and you decide what to do with it. Self-monitoring through the app is free.
Can you add cameras to an alarm system?
Yes. ZonaShield does both on the same job. Many customers get cameras and an alarm installed together — one trip, one invoice.
What happens to the alarm when the power goes out?
All alarm panels have battery backup. A standard system runs 4–8 hours on backup power, which covers most Arizona outages.
Can I keep my existing sensors if I upgrade the panel?
Sometimes. It depends on the brand and sensor type. We’ll check compatibility during the estimate — we won’t make you replace working hardware you don’t need to.
