Intrusion detection and 24/7 central-station monitored alarm systems — installed and serviced by our own licensed Michigan technicians, no subcontractors.
Michigan Security Systems designs, installs, and services commercial alarm systems for businesses throughout St. Clair Shores and Macomb County. We're a commercial-only integrator serving St. Clair Shores since 2000, with offices in Mount Clemens, Wixom, and Milford — every job done by our own licensed W-2 technicians, never subcontractors.
Door and window contacts, glass-break sensors, and motion detectors engineered around how your St. Clair Shores building is actually used.
Live Michigan operators on call around the clock — fast verification and dispatch when an alarm trips at your St. Clair Shores property.
Arm, disarm, and get instant alerts from your phone — with user codes and schedules for each employee or shift.
Alarm events linked to camera footage and access logs, so after-hours incidents are fully documented.
St. Clair Shores is a lakeside community of marinas, restaurants, medical and dental offices, and neighborhood retail. We work across the Harper Avenue and Jefferson Avenue commercial corridors, the Nautical Mile, and the 9–11 Mile retail strips — serving restaurants and hospitality, marine and recreation businesses, medical and dental practices, and retail — and we size every alarm system around how the building is actually used, not a one-size template.
From the Nautical Mile on Jefferson, Lake St. Clair marinas, and the Harper corridor, our technicians know this market. We respond to St. Clair Shores and all of Macomb County directly, integrate your alarm system with your cameras and access control, and back everything with local service and 24/7 support — not an out-of-state call center.
Along the Nautical Mile and Harper corridor, St. Clair Shores businesses — restaurants, marinas, and medical offices — need weatherproof exterior coverage and reliable after-hours alarms. We design cameras that handle lakeside conditions and monitored intrusion detection sized for smaller commercial buildings.
Whether you run a single storefront or multiple St. Clair Shores-area locations, we'll walk the site, recommend exactly what the building needs, and give you a fixed written quote before any work starts. Then our own licensed technicians handle the install and stand behind it.
It depends on building size, number of openings, and sensor types. We assess your St. Clair Shores facility on-site and give a fixed written quote, plus a clear monthly monitoring rate with no surprise fees.
