Home security in McKinney
Our McKinney neighbors ask for two things from a home system. It has to work, and someone has to answer when it goes off. We install alarm panels, indoor and outdoor cameras, video doorbells, and smart locks, then connect them to round-the-clock monitoring. Residential monitoring starts as low as $19.99 a month.
McKinney keeps adding rooftops, from the Craig Ranch area to the newer communities north of US-380. That means a lot of first-time homeowners who want their system set up right the first time. We handle that on-site and in person, not over a chat window. See our home security options.
Commercial security for McKinney businesses
From retail along US-75 to offices near the Sam Rayburn Tollway, McKinney businesses need cameras that hold up in court, access control that logs who opened what, and alarms that get a real response. We build business camera systems, card and mobile access control, and commercial alarms, and we monitor them 24/7 through a UL-listed central station. Commercial monitoring starts as low as $29.99 a month, which is a rate almost nobody in the DFW market publishes.
Texas rewrote its Organized Retail Theft law in September 2025, so this is a smart time for local shops and warehouses to tighten up. Explore our commercial security systems.
Mobile surveillance trailers for McKinney job sites
Copper and equipment theft is a live problem on Collin County job sites, and it usually happens in the small hours after the crew leaves. AT&T alone spent more than $1 million repairing copper and fiber theft damage across DFW, and one Dallas theft knocked out part of the city’s 911 service (NBC DFW).
Our solar-powered mobile surveillance trailers drop onto a site with no power, no internet, and no fence required, then relocate as the build moves. They pair action-activated cameras with live monitoring and talk-down, so an operator can respond the moment something moves.

McKinney alarm permits and “No Permit, No Response”
McKinney takes alarm registration seriously. If your system can summon the police, the city requires a permit, currently $50 a year for homes and $100 a year for businesses, and it has enforced a No Permit, No Response policy since 2007. An unregistered system will not get a police dispatch. You can register through the city’s alarm program, and you can reach the McKinney Alarm Unit at (972) 547-2820. Full details are on the City of McKinney alarm permits page. We handle this step with every customer so nothing falls through the cracks.
Why McKinney chooses a local security team
We have run this business out of McKinney for 26 years. When you call, you reach a local company with local technicians, not a national call center reading from a script three states away. We deploy and service quickly because we are already here.
Our contracts flex to fit you, month-to-month or long-term, your choice, and financing is available. Every job starts with a free on-site consultation and a straight estimate, with no hidden fees. North Texas hail and severe storms are hard on outdoor equipment, so we spec gear that can take the weather. That local knowledge is the difference between a system that lasts and one that fails the first bad summer.
Frequently asked questions
Do I need an alarm permit in McKinney?
Yes. If your alarm system can summon McKinney police, the city requires a permit, and it runs a No Permit, No Response policy that has been in place since 2007. Current fees are $50 a year for residential systems and $100 a year for commercial. We walk every customer through registration so your system is covered from the first day it is armed.
Does someone actually watch my system, or does it just send me alerts?
Both. You get alerts, and your system is backed by 24/7 professional monitoring through a UL-listed central station. When an alarm trips, a real person responds. On our mobile surveillance trailers, that includes live talk-down through on-unit speakers so an operator can warn off an intruder in real time.
How much does security monitoring cost in McKinney?
Residential monitoring starts as low as $19.99 a month and commercial monitoring starts as low as $29.99 a month. Equipment, installation, and mobile surveillance trailers are quoted per job after a free on-site consultation, because the right setup depends on your property.
Do you cover new construction homes and job sites around McKinney?
Yes. We set up systems for new-build homes across McKinney and greater Collin County, and we deploy solar-powered surveillance trailers on active construction sites and equipment yards where there is no power, internet, or fencing yet. The trailer relocates as the site changes.
