A Small City Growing Fast
Melissa is a Collin County city along US-75 and SH-121, north of McKinney, served by a single ZIP code, 75454. The 2020 census counted about 13,900 residents, and current estimates put the city near 30,000, one of the fastest growth rates in the county. Most new residents live in recently built subdivisions, and new shops, restaurants and services are opening to keep up.
That makes Melissa mostly a home and neighborhood market, with a growing list of small businesses. A1 Security Gate & Intercom, based in Allen just down US-75, installs systems sized for both.
Home Cameras That Actually Help
Most homeowners we talk to in Melissa already have a battery doorbell or a camera from a big-box store, and most are frustrated: blurry faces, missed motion, dead batteries and monthly fees. We install wired cameras that do the job:
- Front door: a wired video doorbell that sees faces and packages clearly.
- Driveway and street: a camera aimed to capture vehicles coming and going.
- Side gates and backyard: coverage of the paths people actually use to get behind the house.
- Local recording: video stored on a small console in your home, viewable from your phone, with no monthly fee per camera for core features.
In newer homes we can usually run wiring through the attic with very little visible cable.
Neighborhood Gates and Amenities
For Melissa HOAs and gated sections, we install and repair gate operators, replace telephone-entry units with cellular or app-based call boxes, and add access control to pools and amenity centers so residents use one credential and the board manages everyone from a web portal.
New Businesses on US-75 and SH-121
For shops, restaurants, clinics and offices, we install cameras on entrances, registers, back doors and parking, and card or phone access on staff and storage doors. Most complete commercial doors run about $3,000–$3,500 including professional-grade hardware, installation and programming. If you are building out a new space, bring us in before the ceilings close.
Package Theft and Driveway Break-Ins
The two problems Melissa homeowners mention most are porch package theft and vehicles rummaged through overnight. Both are solved by placement, not by adding more cameras. For packages, a wired doorbell captures the face at the door and a second camera on the porch from a higher angle catches the walk-up and walk-away. For driveways, a camera on the garage corner aimed down the drive captures people approaching vehicles, with smart detection so you are alerted to a person at 3 a.m. but not to every car that passes on the street.
If you already have cameras that are not doing the job, we can often re-aim or relocate them and add only what is missing.

Melissa sets its own requirements for alarms, community gates and access-controlled exits. We confirm current requirements for your address before installation. See our permits guide.
