Certified Systems Inc. was created in 1984, and has grown rapidly. We offer a variety of services to homes, businesses and the construction industry throughout Northern California.

Certified Systems is a local alarm company with employees that reside in local communities. Unlike national alarm companies, your dollars stay in the same communities we live in and our employees continue to support other local businesses.

Certified Systems is far more than an alarm system provider. We take pride in taking our time with you to design the best alarm system possible. Part of that commitment to you is a reliable alarm system. Part of our solution lies within cellular-gsm and CSAirLink communication methods to our Central Monitoring Station.  We have the most diverse and reliable communication methods in the industry. Rather than Butte County…too confining.

Whether you need a home or commercial security system, you can trust that we will do our best to create peace of mind for you, your family and your business. We are here to provide you with 100% satisfaction in all aspects of our products and services. To ensure this, we only install quality components that are installed by highly trained, NICET certified technicians

As a home alarm company, you can trust that we will help protect you and your family from fire and intrusion. Certified Systems offers premier intrusion systems backed up by our U.L listed Central Monitoring Station. We custom build every home security system with your needs in mind.

As a commercial alarm systems provider, you can trust that we will help protect your business and your property. We offer design and installation services for security and alarm systems ranging from access control, security cameras, motion detectors, CCTV and surveillance equipment, fire alarms and safety systems.

Whether you’re a homeowner, general contractor, or business owner, Certified Systems has solutions for you. We are not just a security company; we are the solution for true piece of mind.
