Our Reputation For Quality Service Is Unequalled

The primary reason we’ve earned our reputation as Southern California’s premier security system company is our relentless commitment to service – a culture we’ve nurtured since we opened in 1987.

We’ll design a system that’s tailored to your site, ensuring optimal coverage and protection.

Our trained technicians will install your system, ensuring it’s set up correctly and functioning as intended.

With 24 hour security monitoring, our central station personnel notify you and contact the appropriate authorities when the alarm sounds.

Our service technicians are committed to providing you with the highest quality maintenance and repair of your system in a timely, efficient manner.

We have a fire detection testing department that visits all our fire accounts semi-annually to perform fire tests in accordance with NFPA.
