McKinney pairs a historic downtown square with fast new growth. A1 secures both — older buildings and brand-new development — with access control, cameras, intercoms and reliable gate service.
McKinney is unusual in the metroplex: the seat of Collin County, with a beloved historic downtown square of older brick buildings, set against some of the fastest growth in Texas out toward Craig Ranch and the western corridors. Securing McKinney means handling both — wiring a century-old downtown storefront and a brand-new commercial build with equal care.
A1 Security Gate & Intercom installs access control, surveillance, intercom and gate systems tuned to each. Historic downtown spaces often need discreet, minimally invasive installs that respect the building; new development is the ideal time to pre-wire and design security in from the start. We do both, plus service McKinney’s many gated communities and HOAs.
For McKinney homeowners — from established neighborhoods to new master-planned communities — we install discreet cameras, smart entry and driveway gate operators. Licensed (TX #B31188501) and insured, with same-day and 24/7 service, we are a local team built for a city balancing its history with rapid growth.
