You know Houston's crime stats. You've seen the neighborhood posts. That anxiety when you're out of town or the kids are home alone—it's real.
A properly installed alarm system changes that. You get alerts the second something's off. Cameras let you check in from anywhere. And if an alarm triggers, trained monitors verify the threat and dispatch help faster than you ever could from your phone.
The difference isn't just equipment. It's knowing someone local installed it right, programmed it for your home, and will pick up the phone when you call. That's what over 700 Houston families have with us—and why most of our customers come from referrals.
Choose the security solution that fits your needs. All plans include 24/7 professional monitoring and local Houston-area support.
Archangel Alarm Services isn't a national call center. We're a family-owned Houston business that's been installing and monitoring security systems across Harris County since 2008.
We've earned our Angie's List Super Service Award and Best of Home Advisor recognition by showing up on time, explaining your options clearly, and actually answering the phone when you need us. No scripts. No runaround.
If you've got an existing system that just needs monitoring, we'll activate it—often the same day you call. If you're starting from scratch, we'll walk your property, recommend what actually makes sense, and install it within 24 to 48 hours. You're not locked into multi-year contracts, and you're not talking to someone in another state when something goes wrong.
From smart home security to 24/7 professional monitoring — discover the full range of solutions we offer to protect what matters most.

You call or submit a request. We schedule a time that works for you—usually within a day or two. If you've already got equipment installed, we can often activate monitoring the same day.
During the consultation, we walk your property and talk through what you actually need. Motion detectors, door sensors, cameras, smart locks—whatever fits your home and your concerns. We don't upsell. We recommend what makes sense.
Installation typically happens within 24 to 48 hours. Our techs mount equipment, test every sensor, connect your system to 24/7 monitoring, and show you how to use it. If you want mobile access or smart home integration, we set that up too.
After install, you've got our direct number. No phone trees. No offshore support. When you call, you talk to someone who knows your system and can help immediately.
Every system we install includes 24/7 professional monitoring. When your alarm goes off, our monitoring center gets the signal within seconds. They verify whether it's real, then dispatch police or fire if needed. You're not stuck trying to call 911 while panicking.
You'll get door and window sensors on entry points, motion detectors in key areas, and a control panel that's simple to arm and disarm. Most customers add cameras—video doorbells, outdoor cams, or interior monitoring. All of it connects to an app so you can check in from anywhere.
Houston's property crime rate sits around 31 incidents per 1,000 residents. Porch theft spikes every holiday season. Break-ins happen in every neighborhood, not just the "bad" parts. A visible security system alone makes your home less of a target—84% of people feel safer when their neighbors have one.
We also install fire alarms with rapid detection and automatic dispatch. In a city where response times matter, every second counts. Your system can include smart locks, lighting controls, and automation that makes it look like someone's home even when you're not.
Yes. Most of the time, we can. If you've already got equipment installed—even if it's old or hasn't been used in years—we can usually add cellular monitoring and reactivate it.
A lot of Houston homeowners have hardwired systems from previous owners or old contracts they let expire. Instead of ripping everything out, we assess what's there, replace outdated components if needed, and connect it to our monitoring service. You're often looking at our $17/month monitoring plan instead of paying for a full reinstall.
We'll come out, test your sensors and panel, and tell you honestly whether it's worth keeping or starting fresh. If the equipment's too outdated or incompatible, we'll explain why and give you options. But more often than not, you're back up and running the same day we visit—without spending thousands on new gear.
Most installations happen within 24 to 48 hours of your call. If you've got an existing system that just needs monitoring, we can activate it the same day in many cases.
For new installs, we schedule a walkthrough first. We look at your home's layout, talk through your concerns, and recommend equipment. Once you approve the plan, we order any components we don't have in stock and schedule the install—usually within a day or two.
The actual installation takes a few hours depending on the size of your home and how many devices you're adding. We mount sensors, run any necessary wiring, program the system, test everything, and connect it to monitoring. Before we leave, we walk you through how to use it and make sure you're comfortable with the app and controls.
No. We don't require long-term contracts. You're not locked in for three or five years like you are with most national companies.
Our monitoring plans are month-to-month. If you're not happy or your situation changes, you're not stuck paying penalties to get out. That's part of being a local business—we keep your service because you're satisfied, not because you're trapped in paperwork.
The $17/month plan covers existing systems with cellular monitoring. Our full-service plans with professional installation and equipment start higher, but you're still not signing away years of your life. We'd rather earn your business every month than lock you into something you'll regret.
When your alarm triggers, our 24/7 monitoring center receives the signal within seconds. A trained operator sees which sensor was tripped and begins verification immediately.
They'll call your primary contact number first. If you answer and provide your passcode, they'll cancel the dispatch. If you don't answer, or if you can't provide the code, they assume it's a real emergency and contact police or fire services right away. They'll also try your secondary contacts.
This is faster than you calling 911 yourself—especially if you're not home or can't get to your phone. The monitoring team has your address, your system details, and direct lines to local dispatch. In a city like Houston where response times vary by neighborhood, every second counts. Professional monitoring gets help moving while you're still figuring out what's happening.
Yes. Every system we install includes mobile app access. You can arm and disarm from anywhere, get instant alerts when sensors trigger, and view live camera feeds if you've got video.
The app also lets you control smart locks, check whether doors are open or closed, and even adjust lighting or thermostats if you've integrated those devices. A lot of our customers check their cameras multiple times a day—especially parents who want to see when kids get home from school.
You'll get push notifications the moment something happens. Door opens. Motion detected. Alarm triggered. You're not waiting for an email or wondering what's going on. And if you're out of town, you can monitor everything in real time and respond immediately if something looks off. It's one of the most-used features our customers mention—that peace of mind of always knowing what's happening at home.
It depends on what you need. If you've already got equipment and just need monitoring, our $17/month plan covers that. If you're starting from scratch, costs vary based on the size of your home and how many devices you're adding.
A basic system with door sensors, motion detectors, and a control panel typically runs a few hundred dollars for equipment plus monthly monitoring. Add cameras, smart locks, or fire alarms, and the upfront cost goes up—but you're building a system that actually fits your home instead of paying for a one-size-fits-all package.
We don't do high-pressure sales or bait-and-switch pricing. During your consultation, we'll walk your property, recommend what makes sense, and give you a clear quote before any work starts. Most Houston families spend between $200 and $600 on DIY starter systems, or $45 to $65+ per month for professionally installed setups with monitoring. We're transparent about what things cost and why—so you can make the call that fits your budget and your needs.
