Home security in Frisco
Frisco is a high-income, high-delivery suburb, which makes it a favorite target for porch pirates and opportunistic break-ins. We install alarm panels, indoor and outdoor cameras, video doorbells, and smart locks, then tie them to round-the-clock monitoring. Residential monitoring starts as low as $19.99 a month. Whether you just closed on a new build near the Dallas North Tollway or you have lived off Legacy Drive for years, we set the system up in person and show you how to use it.

Commercial security for Frisco businesses
Frisco’s business base keeps expanding. The city added 14 corporate relocations and expansions in fiscal 2025, more than 3,100 jobs and over $500 million in investment, alongside mixed-use projects like The Mix and Fields West. Those offices, shops, and restaurants need cameras that hold up as evidence, access control that logs who opened what, and alarms that get a real response. Commercial monitoring starts as low as $29.99 a month, a rate almost nobody in DFW publishes. With Texas tightening its Organized Retail Theft law in September 2025, it is a smart time to tighten up security. Explore our commercial security systems.
Mobile surveillance trailers in Frisco
New development is everywhere in Frisco, and active job sites draw copper and equipment thieves who strike after the crew goes home. AT&T alone spent more than $1 million repairing copper and fiber theft across DFW (NBC DFW). Our solar-powered surveillance trailers deploy where there is no power, internet, or fence, pair action-activated cameras with live monitoring and talk-down, and relocate as the build moves. Learn about our mobile surveillance trailers or read the DFW trailer cost guide.
Frisco alarm permits
Frisco requires an alarm permit within 30 days of installing a monitored system, currently $100 for commercial and $35 a year for residential. You can register through the city, and the Frisco Police alarm unit is reachable at (972) 292-6062. Full details are on the City of Frisco alarm permits page. We walk every customer through registration so the system is covered from day one.
Why Frisco chooses a local security team
We run this business out of McKinney, about 20 minutes from most of Frisco, so a local technician handles your install and service, not a national call center. Our contracts flex month-to-month or long-term, financing is available, and every job starts with a free on-site consultation. North Texas hail and hard summers wear on outdoor gear, so we spec equipment built to take the weather.
