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 Port Huron and St. Clair County. We're a commercial-only integrator serving Port Huron 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 Port Huron building is actually used.
Live Michigan operators on call around the clock — fast verification and dispatch when an alarm trips at your Port Huron 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.
Port Huron is a border-city hub with the Blue Water Bridge crossing, downtown retail, marine industry, and healthcare. We work across the downtown Military Street district, the Pine Grove and 24th Street corridors, and the Blue Water Bridge commercial zone — serving cross-border logistics, marine and manufacturing, healthcare, hospitality, and downtown retail — and we size every alarm system around how the building is actually used, not a one-size template.
From the Blue Water Bridge, the Thomas Edison Depot, and the downtown Military Street district, our technicians know this market. We respond to Port Huron and all of St. Clair 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.
As a border city with the Blue Water Bridge, Port Huron sees cross-border logistics, marine industry, and a walkable downtown. We cover yards and docks, downtown storefronts, and healthcare facilities, with monitored alarms and remote viewing so owners can check multiple sites from one app.
Whether you run a single storefront or multiple Port Huron-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 Port Huron facility on-site and give a fixed written quote, plus a clear monthly monitoring rate with no surprise fees.

Yes. You control arming, disarming, user codes, and schedules from a secure mobile app, and get instant alerts for any event at your Port Huron location.
