You're not just buying equipment. You're buying the ability to leave for work without wondering if someone's watching your house. You're buying the peace of mind that comes with knowing a trained operator is monitoring your home 24/7, ready to dispatch help the moment something's wrong.
Most Missouri City homeowners worry about break-ins when they're away. That's not paranoia—44% of people share that same concern. A professional alarm system doesn't eliminate every risk, but it does give you control back. Motion detectors catch movement before anyone gets inside. Video doorbells let you see who's at your door from anywhere. Smart locks mean you'll never wonder if you forgot to lock up again.
The real benefit isn't the technology. It's what happens after: less anxiety, better sleep, and the confidence that your family and property have a layer of protection that actually responds when it matters.
Choose the security solution that fits your needs. All plans include 24/7 professional monitoring and local Houston-area support.
We're a family-owned security company that's been serving the Houston area since 2008. We've installed and monitored alarm systems for over 700 homes and businesses, and we're fully licensed and insured.
Missouri City is a great place to live—quiet neighborhoods, good schools, families who care about their community. But even in safer areas, property crime happens. We understand what local homeowners face because we live here too. Hurricane season means you need backup power that keeps your system running when the grid goes down. High humidity and heat mean equipment has to hold up year-round.
We've earned recognition like the Angie's List Super Service Award and Best of Home Advisor, but what matters more is how we treat people. You'll work with the same local team from consultation to installation to ongoing support. No call centers. No runaround.
From smart home security to 24/7 professional monitoring — discover the full range of solutions we offer to protect what matters most.

First, you call or message us to schedule a consultation. We'll ask about your home layout, your main concerns, and what you're hoping to protect. This usually takes 15-20 minutes and helps us recommend the right setup without overselling equipment you don't need.
Next, we'll schedule your installation—often same-day or within 24-48 hours. Our technician arrives on time, walks through the plan with you, and installs your alarm system, cameras, sensors, and any smart devices you've chosen. Most installations take 2-4 hours depending on the size of your home and the complexity of the system. We test everything before we leave and show you exactly how to arm, disarm, and control your system from your phone.
After installation, your system connects to our 24/7 monitoring center. If an alarm goes off, trained operators verify whether it's a real threat or a false alarm, then contact you and dispatch emergency services if needed. You'll also get access to remote monitoring through an app, so you can check cameras, lock doors, or adjust settings from anywhere.
If you ever have questions or need service, you call us directly. No contracts means you're not locked in, but most customers stay because the system works and the support is responsive.
Your alarm system includes door and window sensors, motion detectors, a control panel, and a backup battery that keeps everything running during power outages—critical during hurricane season in Missouri City. Most systems also include cellular communication, which means your alarm works even if your internet goes down.
You can add video doorbells, indoor and outdoor security cameras, smart locks, and smart lighting. These integrate with your alarm system so you control everything from one app. See who's at the door while you're at work. Lock up remotely if you forgot. Turn lights on and off to make it look like someone's home.
Every system comes with professional monitoring. That means trained operators watch your property around the clock. If your alarm triggers, they verify what's happening, contact you, and send police or fire services if there's a real emergency. This isn't a recorded message or an automated text—it's a real person responding in real time.
We also work with existing systems. Many Missouri City homeowners already have alarm equipment installed by a previous owner or an old provider. In a lot of cases, we can activate and monitor what's already there without replacing everything. That saves you thousands and gets you protected faster.
Most professionally installed alarm systems in Missouri City range from $300 to $1,500 for equipment, depending on the size of your home and what you want included. Basic setups with door sensors, motion detectors, and a control panel start around $300-$500. If you add cameras, smart locks, and more sensors, you're looking at $800-$1,500.
Monthly monitoring typically runs $30-$60. That covers 24/7 professional monitoring, cellular backup, and app access. Some companies charge extra for camera storage or smart home integration, but we include that in our monitoring plans.
If you already have an alarm system installed, we can often activate and monitor it without replacing anything. That drops your upfront cost significantly—sometimes to zero if the equipment is compatible. We'll assess what you have during the consultation and give you an honest recommendation about whether you need new equipment or if what's there will work.
You can self-monitor through an app, but here's what you give up: someone watching your home when you're asleep, in a meeting, on a plane, or anywhere you can't respond immediately. If your alarm goes off at 2 a.m. and you're out of town, a professional monitoring center verifies the threat and dispatches police. If you're self-monitoring, you get a notification—and then you have to call 911 yourself, explain the situation, and hope response times are fast.
Professional monitoring also reduces false alarms. Operators can see what triggered the alarm and verify whether it's an actual break-in or your dog setting off a motion sensor. Police departments in Missouri City and across Texas have started fining homeowners for repeated false alarms, and monitored systems have significantly lower false alarm rates because someone's confirming the threat before dispatch.
Most of our customers choose professional monitoring because it's the whole point of having a security system. You're not just buying equipment—you're buying a response when something goes wrong.
Yes, if it's set up correctly. Every system we install includes a backup battery that keeps your alarm, sensors, and control panel running during power outages. Most backup batteries last 12-24 hours, which covers the majority of outages in Missouri City.
We also install cellular communication on every system. That means your alarm doesn't rely on your internet or phone line to send signals to the monitoring center. Even if your power and internet go out during a storm, your system stays connected and monitored.
This is especially important during hurricane season. Missouri City sits in a region that sees severe weather, flooding, and occasional evacuations. If you're away from home during a storm, you want to know your security system is still protecting your property. Cellular backup and battery power make that possible. We've had systems stay online for days during extended outages, and customers tell us that peace of mind is worth the investment alone.
In many cases, yes. A lot of Missouri City homes have alarm systems installed by previous owners or old security companies that went out of business or stopped providing service. Most of that equipment still works—it just needs to be reactivated and connected to a monitoring center.
We'll come out, assess what's already installed, and test the sensors, panel, and wiring. If everything's functional and compatible, we can activate it and start monitoring without replacing anything. That saves you hundreds or even thousands in equipment costs.
If the system is outdated or incompatible with modern monitoring, we'll explain why and give you options. Sometimes it makes sense to replace the panel but keep the sensors. Other times a full upgrade is the better move, especially if you want smart home integration or remote access. We'll walk you through the pros and cons so you can make the call that fits your budget and needs.
Most alarm system installations take 2-4 hours depending on the size of your home and how many devices you're adding. A basic setup with door sensors, motion detectors, and a control panel is usually closer to 2 hours. If you're adding multiple cameras, smart locks, and additional sensors, it can take 3-4 hours.
We do our best to minimize wall damage. Wireless sensors don't require drilling through walls or running wires, so installation is cleaner and faster. If we do need to mount cameras or run wiring for specific devices, we'll show you where and get your approval first. Any holes we make are small and easy to patch if you ever move or remove equipment.
Our technicians have done this hundreds of times. They know how to work around your home without leaving a mess. We'll also walk you through how everything works before we leave, so you're comfortable using the system right away. If you have questions later, you can call us directly—no waiting on hold with a national call center.
We don't lock you into long-term contracts, so you can cancel anytime without penalties or fees. If you move, you have a couple of options: take your system with you, transfer monitoring to the new owner, or cancel service.
If you're moving within the Houston area, we can often relocate your equipment to your new home. There may be a reinstallation fee depending on the scope of the move, but you keep the same system and monitoring plan. If you're moving out of state or the new homeowner wants to keep the system, we can transfer the monitoring agreement to them with their approval.
Most security companies require 2-3 year contracts with hefty cancellation fees. We don't do that because we'd rather earn your business by providing good service than trap you in a contract. Our customers stay because the system works and the support is reliable—not because they're stuck.
