What a Group One access control system does
Every system is built around how your building actually runs: who needs access, to which areas, and at what times. A typical installation includes:
Access control built for the way you work
One local team handles the design, installation, and support.
Key Card & Fob Entry
Proximity cards and fobs for staff and tenants, issued and revoked in seconds, with no lock to rekey when one goes missing.
Mobile & Smartphone Credentials
Let employees use their phone as their credential. Convenient for staff and easy for you to manage remotely.
PIN & Keypad Access
Code-based entry for lower-traffic doors, storage areas, and spaces where cards are not practical.
Door Schedules & Automation
Doors that unlock for business hours and lock automatically after, with custom schedules for holidays and events.
Audit Trail & Reporting
A complete record of who entered where and when, ready when you need it for an incident or a compliance request.
Multi-Site Management
Manage every door across multiple Stuart, Palm City, and Treasure Coast locations from one dashboard.
Alarm & Camera Integration
Tie access events to your intrusion alarm and cameras, so an unlocked door and the video of it live in one place.
Visitor & Contractor Access
Temporary credentials for guests, vendors, and contractors that expire on their own.
Where access control fits in Martin County
We design systems around the specific needs of the facility.
Medical Offices & Clinics
Restrict access to records rooms, medication storage, and staff-only areas while keeping waiting rooms open.
Professional Offices
Controlled entry for law firms, financial advisors, and real estate offices, with a log of after-hours access.
HOAs & Gated Communities
Amenity centers, clubhouses, pool gates, and fitness rooms secured for residents only.
Retail & Restaurants
Protect stockrooms, offices, and back-of-house areas from front-of-house traffic.
Warehouses & Industrial
Layered access across docks, yards, and interior zones for larger facilities west of the Turnpike.
Multi-Tenant Buildings
Per-tenant access, shared entrances, and single-source management for property managers.

Access control questions
Can I add or remove someone's access remotely?
Yes. You can grant or revoke any credential from a browser or app, so a lost fob or a departing employee is handled in seconds, from anywhere.
What kinds of credentials can we use?
Key cards, fobs, mobile phone credentials, and PIN codes, in any mix. We match the credential to each door and how it is used.
Can access control work with our alarm and cameras?
Yes. We integrate access with intrusion alarms and video, so an entry event and its footage are tied together under one system.
Do the doors lock and unlock on a schedule?
Yes. Doors can unlock for business hours and lock automatically after, with custom schedules for holidays, events, and different areas of the building.
Can you manage more than one location?
Yes. Multiple sites across the Treasure Coast can be managed from one dashboard, with per-location and per-person control.
What happens during a power outage?
Systems are designed to fail safe or fail secure by door, based on code and your needs, with battery backup so access and egress work correctly during an outage.
Can you take over an existing access control system?
Often, yes. We evaluate the current hardware and software, then upgrade, expand, or replace it depending on condition and what it supports.
