Home security in Plano
From the established neighborhoods around Los Rios and Willow Bend to the newer builds in far west Plano near Legacy West, homeowners want a system that works and a response when it matters. We install alarm panels, cameras, video doorbells, and smart locks, then connect them to round-the-clock monitoring. Residential monitoring starts as low as $19.99 a month. We also tie in home automation through Alarm.com, so your lights, thermostat, and locks work together and you can check the house from your phone while you are at the office or out of town. See our home security options.
Commercial security for Plano businesses
Plano packs one of the densest corporate corridors in Texas, from Legacy West to the offices along US-75 and the Dallas North Tollway. Access control is where a lot of these businesses start. In a multi-tenant building or a company spread across several floors, you need to know who can open which door and when, cut off a badge the day someone leaves, and pull an access log if something goes missing. We install card, fob, and mobile-credential systems with cloud management, so an office manager runs the whole thing from one dashboard. Pair that with business cameras and 24/7 monitoring through a UL-listed central station, and the system grows with the company. Commercial monitoring starts as low as $29.99 a month. Explore our commercial security systems.
Protecting Plano retail and restaurants
The retail and dining along US-75 and Preston Road faces a different risk profile than a quiet office park: shoplifting, organized retail crime, and after-hours break-ins. We set up camera coverage at entrances, registers, and stockrooms, integrate with the point of sale where it helps, and add monitored alarms so a real person responds overnight instead of a siren nobody hears. Texas strengthened its Organized Retail Theft law in September 2025, which makes clean, usable footage more valuable than it has ever been for building a case.
Mobile surveillance trailers in Plano
Plano’s redevelopment and construction sites face the same overnight theft problem as the rest of the metro, and copper theft has grown costly enough to knock out part of Dallas 911 service (NBC DFW). Our solar-powered surveillance trailers cover a whole site with action-activated cameras, live monitoring, and talk-down, and they need no power or fencing to run. They relocate as the project moves through each phase. Learn about our mobile surveillance trailers or read the DFW trailer cost guide.
Plano alarm permits
Plano takes alarm registration seriously. The city’s police and fire departments respond to roughly 12,000 false alarms every year, so a monitored system needs a permit. We handle registration for you, and the Plano alarm unit is reachable at (972) 941-2426. Details are on the City of Plano alarm permits page.
Why Plano chooses a local security team
We are a local Collin County company, not a national call center reading from a script. A local technician handles your install and service, our contracts flex month-to-month or long-term, and financing is available. Every job starts with a free on-site consultation and a straight estimate, with no hidden fees. We spec outdoor gear that stands up to North Texas hail and heat, because equipment that fails in the first bad storm is not protection.
