We compared 17 home security systems in Austin on Google Maps · 5 listed · How we rank

A home alarm is only as good as the company that installs it, monitors it and shows up when a sensor fails. The home security systems in Austin below hold more than 1,500 Google reviews between them, rated 4.8 or higher, and one national-brand office alone has more than 500, so the question is less who is good than who fits your house and your budget.

Securimax Inc. and Smith Thompson Home Security and Alarm Austin both hold 4.9 on more than 360 reviews. Smith Thompson's website lists wireless monitoring from $16.95 a month with no term contract.

Our take: It carries the largest review base on the page and reviews that cover installs, upgrades and later fixes. A sensible default for a standard alarm setup, with the caveat that it is a branch of a national company.

How we score

Every number on this page comes from public Google data on the date shown, not from opinion or payment. Rating is the live Google star average. Review volume is how many customers have rated the business, compared with other Austin security companies. Confidence weighs the rating by that volume, so a 4.8 from hundreds of people carries more weight than a 5.0 from fewer. Recency reflects how recently customers are still leaving reviews. No business can pay to change these numbers.

What does home security cost in Austin? (2026)

Smith Thompson publishes plan prices on its site. Ask the others for a written quote. Costs vary with the equipment, the number of sensors and cameras, and whether monitoring is month to month or on a term.

JobTypical price
Wireless monitoring plan, using an existing system (Smith Thompson, per its website)$16.95 per month plus $89 one-time

From the Smith Thompson Home Security and Alarm Austin website, as of October 2026. Plans change, so ask each company for a written quote covering equipment, installation, monitoring and any contract terms.

Alarm companies across Austin

These companies are based in north and northwest Austin, with Securimax in Hutto and Blue Line Security in Round Rock. Securimax and Blue Line both say they serve the wider Austin area. Searching for home security near me? Each listing shows a phone number so you can confirm your address is covered.

What to ask before you sign for a security system

  • Is monitoring on a term contract or month to month, and what does early cancellation cost?
  • Who owns the equipment and does it work with another provider if I leave?
  • Is monitoring done in house or by a third party?
  • Will you give a heads-up before the technician arrives?
  • What happens when a sensor or panel fails, and how fast do you come out?

Frequently asked questions

Do Austin alarm companies require a long contract?

It depends on the company. Smith Thompson’s website advertises no term contract and a reviewer describes its service as month to month. Ask the other companies about term length and cancellation before you sign.

Are all of these security companies based inside Austin?

No. Securimax Inc. is based in Hutto and Blue Line Security in Round Rock, while the others list Austin addresses. Securimax names Austin and Central Texas on its site, and Blue Line names the Austin area. Confirm your address is in a company’s service range.

Which of these suit a business or church rather than a house?

Blue Line Security’s site is aimed at businesses, churches and homes, a Swiff Security reviewer describes protecting a commercial property, and an Alert 360 reviewer had cameras and access control installed for a business. Securimax’s site covers both residential and commercial systems.

The bottom line

Alert 360 Home & Business Security Austin is the safe default on review volume, Securimax Inc. suits a tailored local setup, and Smith Thompson stands out if you want monitoring without a term contract. Whichever you call, get monitoring terms in writing.
