Smart Security. Noble Service. 

With over two decades in the home security industry, our technicians bring deep expertise to every job. We’re committed to delivering exceptional service, honest guidance, and the best value for your hard-earned dollar.

Excalibur Home Security is fully licensed by the Texas Department of Public Safety – Regulatory Services Division (Lic. #B28463701), giving you confidence that you’re protected by true professionals.

San Antonio is a special place — and we believe your protection should come from people who live here, too. Why trust a company halfway across the country that can’t even pronounce Bexar County?

We’re locally owned, locally operated, and locally monitored. Because home security should feel… well, local.

Excalibur is a small, San Antonio-based company — and that’s exactly why we care more.

We’re an authorized Alarm.com provider, offering the same cutting-edge tech as the big guys, with none of the contracts or corporate runaround.

You get personalized service, custom solutions, and a team that treats you like a neighbor, not a number.
