McKinney pairs a historic downtown square with some of the fastest growth in Texas. A1 secures both, from century-old brick storefronts to new offices, airport-area businesses, HOAs and homes.
McKinney is the seat of Collin County and a city of more than 200,000 people. Its historic downtown square, built around the old county courthouse, is lined with brick buildings from the late 1800s and early 1900s that now hold shops, restaurants and offices. West and north of downtown, Craig Ranch, Stonebridge Ranch, Tucker Hill and Trinity Falls have added thousands of homes, and the US-75 and SH-121 corridors keep filling with offices, medical buildings and retail.
Securing McKinney means wiring a century-old storefront and a brand-new commercial building with equal care. A1 Security Gate & Intercom installs gates, cameras, access control and intercoms suited to each.

Older brick buildings on and around the square have thick masonry walls, plaster ceilings, transoms and original doors that owners want to keep. We plan cable paths through existing chases, basements and ceilings, choose compact cameras and readers that do not dominate a historic facade, and use electrified hardware that fits the original door where possible. If your building is in a historic district, we can help you think through what exterior equipment will be visible before work starts.
Craig Ranch and the SH-121 corridor hold corporate offices, medical buildings and mixed-use space. For these tenants we install card, phone and PIN access control with schedules and logs, video intercoms at rear and after-hours doors, and camera coverage on entrances and parking. Most complete commercial doors run about $3,000–$3,500 including professional-grade hardware, installation and programming.

McKinney National Airport is adding a commercial passenger terminal scheduled to open in late 2026, and the hangars, aviation businesses and industrial buildings around it are growing. We install hangar and ramp cameras, gate operators with keypads or card readers on airside and parking gates, license plate cameras at vehicle entrances and card access on offices and parts rooms.
McKinney has many gated neighborhoods and HOA entrances, and gate calls are some of our most frequent. We repair and replace operators, control boards, loop detectors, photo eyes and gate hardware from LiftMaster, DoorKing and other brands, and replace outdated call boxes with cellular or app-based call boxes that ring residents’ phones. Service visits are $180, and we offer 24/7 emergency service when a gate is stuck open or closed.

For McKinney homeowners, from older neighborhoods near downtown to new homes in Trinity Falls and the northern subdivisions, we install wired video doorbells, outdoor cameras, driveway gate operators and video intercoms. Video records locally with phone viewing and no monthly fee per camera for core features.
McKinney requires an alarm permit for systems that summon police, at $50 a year for homes and $100 a year for businesses, and the city follows a no-permit, no-response approach. Every access-controlled door must allow free egress, and gates on fire lanes need fire department access. See our permits guide.
