One partner for fire alarm, sprinkler, backflow & code compliance — NFPA-compliant, end to end.
Already have a system? We take over most brands and upgrade you to 24/7 UL-listed local monitoring.
Every system is professionally installed by our own local technicians — never subcontractors — and monitored 24/7 by a UL-listed central station. We build for Florida conditions: hurricane-rated sensors, cellular backup, and equipment that keeps working when the power doesn't.
A local home security company answers with a technician, not a ticket number. National DIY brands ship you a kit and a call center; Group One designs your system in your home, installs it properly, and services it for decades — some of our customers have been with us 38 years. When a sensor fails or a storm knocks out communication, the person who fixes it is twenty minutes away, not three time zones.
Florida homes face risks national security kits aren't designed for. We configure away-mode monitoring for seasonal residents — over half our residential clients spend part of the year elsewhere and watch their Florida homes from their phones.
The best home security system for a South Florida home combines professionally installed intrusion detection, monitored smoke and CO alarms, video surveillance, and smart home integration — with UL-listed monitoring and cellular backup for storm season. A locally installed and supported system outperforms off-the-shelf kits on response time, reliability, and insurance acceptance.
A professionally monitored security system can lower homeowners insurance premiums by 5% to 20%, depending on your insurer and coverage. Group One provides the installation certificate your insurer requires.
Professional monitoring responds even when your phone is off, in a movie, or out of signal. With self-monitoring, an alarm at 3 a.m. is just a notification; with UL-listed monitoring, it's a trained dispatcher contacting you and emergency services within seconds.
Yes — Group One can take over, service, and monitor most existing home alarm systems, usually without replacing equipment. Most switches complete in a single visit.
