Why choose a local home security company over a national brand?

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.

FAQ

Frequently asked questions

What is the best home security system in South Florida?

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.

How much does a monitored alarm lower homeowners insurance?

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.

Do I need professional monitoring, or can I self-monitor?

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.

Can you monitor my existing alarm system?

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.
