For over 60 years, Post Alarm Systems has been the trusted leader in Southern California security systems. Our success is due in large part to our relationship and involvement with the community.

We know that without the ongoing support of our community, Post Alarm Systems wouldn’t be the industry leader it is today. We are honored to give back to the community that has supported our local business for over 60 years. One of our most important goals is to increase safety through education and awareness. Post Alarm is proud of its presence at local events; from serving as volunteer safety staff to supporting local at-risk youth programs, we aim to enrich our community wherever possible.

The ability to give back to our community is a privilege. From local parades and community safety fairs to our annual golf tournament benefiting The Boys and Girls Club, investing in our community is one of our company’s top priorities.


Our unique security analysis process provides a personalized plan for your business or family’s needs.
