“More than a number to call – we’re your neighbor, looking out for you.”



Alarms Unlimited Professional Security Solutions has a legacy in the alarm business stretching way back to 1947. That was the year my father started his burglar alarm company in Redwood City, California. I worked alongside my father in his business before branching out to gain even greater experience and knowledge in the security industry. In 1974 I founded Alarms Unlimited in San Diego.

Alarms Unlimited started out as a burglar alarm and fire alarm company serving residential clients. With a newly built central monitoring station, we took our success in the residential market and applied it to the commercial market. It was only logical that we build on our knowledge and expertise by bringing other technologies into our offerings. We continue to be a leader in integrated security solutions.

Our team members have an extremely high standard of professionalism. We provide thorough training and ongoing skills development. We are proud of our level of retention, as many of our employees have been with us for over 15 years—some as long as 30! We value our employees as our most important asset and each team member takes seriously the partnering relationship between us and our clients. We encourage you to get to know each of our team members personally.


We have been very pleased  and satisfied with the service Alarms Unlimited has provided over a period of more than 15 years. Service is always prompt, professional, knowledgeable and courteous. The security system in our house periodically requires the attention of your office and of your technical staff. In such situations, we are naturally concerned about security. We always felt that our personal security and that of our home was in the best hands with Alarms Unlimited. We would strongly recommend Alarms Unlimited to friends. Our main points would be absolute reliability over many years, immediacy of response in routine as well as in emergency situations, expert technical competence and professional advice and guidance.
