A-1 Takes Your Home and Business Security Seriously

That’s why we offer smarter security solutions.

At A-1 Security, we don’t sell TVs, audio/visual equipment, internet or cable service and we don’t offer guard service. We do one thing and one thing only: electronic security. Because we focus on one thing and do it well, we offer smarter security solutions. Through our state-of-the-art, custom security systems we help you protect what you love most.  

We’re a fourth-generation, family-owned electronic security company with service that you can trust. Not just because we stand by every product we sell, but because the owners are actively involved in the day-to-day operations of the business. We are Colorado-proud, and the foundation of our business is building personal relationships with all of our customers.
