A Local Solution

A Legacy of Protection. A Commitment to the Future.

For over four decades, STOP Alarm has proudly served Porterville and the surrounding Central Valley communities with one mission: to protect what matters most. Since opening our doors in 1978, we’ve built our reputation on reliability, personalized service, and a deep understanding of the unique security needs of homes, businesses, schools, and government facilities in our region.
We’re not just another security company — we’re your neighbors. And we treat your safety like it’s our own.

40 Years of Trust

Our Journey, Your Peace of Mind

From humble beginnings as a local, family-owned business, STOP Alarm has grown into one of the Central Valley’s most trusted names in custom security. Through changing technologies and evolving threats, our values have stayed the same:

  • Integrity in every install
  • Responsiveness in every emergency
  • Accountability in every service call

Our success has always been rooted in long-term relationships with our customers, our community, and our dedicated team members who proudly stand behind our work.

Looking Ahead

As we celebrate this milestone, we remain focused on the future, investing in smarter technologies, expanding our services, and continuing to serve with the same care and commitment we’ve upheld for decades.
