Key fob, card, mobile-credential, keypad, and biometric access control — cloud-managed or on-premise, installed by our own licensed Michigan technicians.
Michigan Security Systems designs, installs, and services card access and access control 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.
Modern credentials — proximity cards, key fobs, and phone-based mobile access — with full entry and exit audit logs.
Cloud-managed access you control from anywhere, or on-site servers when your Port Huron facility requires it. Your choice.
Manage one door or hundreds across multiple Port Huron-area buildings from a single dashboard, with role-based permissions.
Tie access events to camera footage so every badge-in and forced-door alert is backed by video.
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 access control 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 access control 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 the number of doors, credential type, and whether you choose cloud or on-premise management. We give Port Huron businesses a free assessment and a fixed written quote — most start with a few key doors and expand over time.
Yes. Rekeying a Port Huron building every time someone leaves is expensive and insecure. We replace brass keys with cards, fobs, or mobile credentials you can revoke instantly from a dashboard.
Yes. Staff can use their phones as credentials with a secure tap or Bluetooth unlock — popular with Port Huron offices managing shift changes and multiple locations.
We do — directly. As a Michigan integrator serving Port Huron and all of St. Clair County, our own technicians handle programming, changes, and support. No subcontractors.
