Already have a system? We take over most brands and upgrade you to 24/7 UL-listed local monitoring.
A professionally installed home security system protects every entry point of your home with door and window sensors, motion detection, and glass-break protection — monitored 24/7 by a UL-listed central station that dispatches help the moment an alarm triggers. Group One has installed and monitored home security systems across the Treasure Coast, Okeechobee, Brevard, and North Palm Beach since 1984, using our own local technicians and equipment built for Florida storm conditions.
Get a Free Home AssessmentEvery system is designed room-by-room in your home, not picked from a package chart. A typical installation includes:
On doors and accessible windows.
Placed for pets and traffic patterns.
For sliders and picture windows.
With cellular communicator.
Arm, disarm, and get alerts anywhere.
Cameras, smoke & CO, smart locks & lighting, water-leak sensors.
A specialist walks your home, identifies entry points and blind spots, and quotes a fixed price.
Most homes are completed in one visit — wired, wireless, or hybrid depending on your home's construction.
Your system connects to our UL-listed central station the same day, and we walk you through the app before we leave.
The person who designs your system is the person who installs it and the company that answers when you call. That continuity is why Treasure Coast families have stayed with Group One for decades.
Wired home security systems remain the most reliable option for new construction and major renovations; wireless systems install cleanly in finished homes; and if you already have equipment from another company, we can usually take it over and monitor it without replacement.
Most Group One home security installations range from a few hundred dollars for a basic monitored system to more for whole-home coverage with cameras, plus a monthly monitoring fee. Exact pricing depends on your home's size and entry points, which is why every quote starts with a free in-home assessment.
Yes. Every Group One system includes battery standby and cellular backup communication, so monitoring continues when power and internet fail — the exact moment Florida homes need protection most.
A professionally monitored security system can reduce homeowners insurance premiums by 5–20%. We provide the certificate of installation your insurer requires.
Professional monitoring means a trained dispatcher responds to every alarm within seconds — even when your phone is off or you're traveling. Self-monitoring is only as good as your ability to see and act on a notification.
