Our Story
Since 1982, Alarm Security Inc. has been installing peace of mind with electronic security systems for burglary, fire, card access, and video surveillance. Whether the installation is large or small — for a homeowner, an entrepreneur, or a corporation — every client receives ASI's strong technical expertise and a long-term commitment to customer service.
Unlike many of our competitors, we respond within hours, not days, to any problem you might have with your system. As a family-owned company, our reputation is on every installation we complete.
ASI believes an alarm system should make good personal sense and good investment sense. With ASI, security is our only business, so the protection and satisfaction of our clients always come first.
When you work with ASI, you choose more than a security consultant — you select a partner who sees your security as an important responsibility. From our first meeting through installation, long-term monitoring, and follow-up, ASI is with you all the way.
The Value of Security
The feeling of security, safety and comfort that an alarm system provides is invaluable. The investment you make in an alarm system is also of recognized value to your home or business.
