Do the math

Three years with a big alarm company vs. owning it outright.

The alarm industry runs on contracts you forget you signed. Here's what a typical 36-month monitored contract really costs — next to buying the Ajax Home Kit once.

Monthly monitoring × 36 mo~$60 × 36

3-year cost~$2,160+
Typical national-brand professional monitoring plans commonly run $50–60+/month on 36-month terms. Check any contract's fine print.

Monitoring, on your terms

Self-monitor free. Upgrade to 24/7 pros whenever you want.

Out of the box, your kit sends instant alerts straight to your phone — no fee, no middleman. When you want a professional watching too — vacations, travel for work, peace of mind — flip on monitoring. It's month-to-month, and it's never a requirement.

  • Available in Washington — elsewhere, self-monitoring through the Ajax app

How it works

Protected in three steps.

Set it up in under an hour

Your kit arrives pre-configured. Peel, stick, and follow the app — Ajax is fully wireless. Or have our team install it across the South Sound & Greater Seattle, from $390.

Arm from your phone, get instant alerts, pay nothing monthly. Add 24/7 professional monitoring for $44.99/mo whenever you want a central station watching too.

Straight answers

Questions, answered.

Do I have to pay a monthly fee?

No. Every kit works fully without any monthly fee — you arm, disarm, and get instant alerts through the Ajax app at no ongoing cost. Optional 24/7 professional monitoring is available in Washington for $44.99/mo, month-to-month, and you can add or cancel it anytime.

Is there a contract?

No. There's no contract of any kind. You buy the equipment once and own it outright. If you add optional monitoring, it's month-to-month with no penalty to cancel.

What does the optional monitoring include?

For $44.99/mo, a UL-listed central station watches your system 24/7 with cellular backup, verifies alarms, and coordinates a response when it counts. It's available in Washington and it's never required — your system works fully self-monitored through the app.

Can I install it myself?

Yes. Ajax is wireless and app-guided, and your kit arrives pre-configured by our certified team. Most homes are up and running in under an hour. Prefer it done for you? We install across King & Pierce County, WA, starting at $390.

Do you cover my area?

Kits ship anywhere in the U.S. Professional installation is available across the South Sound and Greater Seattle — Kent, Renton, Tukwila, Auburn, Federal Way, Covington, Maple Valley, Tacoma, Puyallup, Seattle, Bellevue, and nearby. Optional 24/7 professional monitoring is available in Washington; elsewhere your kit is self-monitored through the Ajax app.

How is buying a kit cheaper than an alarm contract?

A typical big-brand contract runs about $60/mo for 36 months — roughly $2,160 — and the leased equipment goes back if you leave. The Home Kit is $1,299 once, you own every piece forever, and the required monthly cost is zero. Want professional monitoring later? $44.99/mo, no contract.

Can I expand the system later?

Yes — every Ajax device runs on the same hub and app. Start with a kit and add cameras, sensors, keypads, and smart-home devices from our shop anytime. Want a system designed around your home from day one? Get a free custom quote.
