You get an alert on your phone the second something's wrong. A door opens when it shouldn't. Motion detected in the backyard. Glass breaks. You're not wondering or worrying—you know, and help is already on the way if you need it.
That's what a properly installed alarm system does. It removes the guesswork and gives you actual control over your home security, whether you're at work, running errands, or out of town. You can check your cameras, lock your doors remotely, and get real alerts that matter—not false alarms that make you ignore the system altogether.
Houston sees over 20,000 burglaries a year, and most happen during the day. Your home security system becomes your eyes and ears when you can't be there. It also drops your homeowner's insurance premium, which means the system starts paying for itself from day one.
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 installing and monitoring alarm systems across the Greater Houston Area since 2009. We've secured over 700 homes and businesses, and we're fully licensed and insured in Texas.
We're not a national call center. When you call, you talk to someone local who knows Settegast, understands Houston's crime patterns, and has probably worked in your neighborhood before. We don't push equipment you don't need, and we don't lock you into contracts that don't make sense.
Our customers stick with us because we show up on time, explain things clearly, and actually answer the phone when something goes wrong. We won the Angie's List Super Service Award in 2018 and Best of Home Advisor in 2019—not because we paid for them, but because our customers said we earned them.
From smart home security to 24/7 professional monitoring — discover the full range of solutions we offer to protect what matters most.

First, we come to your home and walk through it with you. We're looking at entry points, blind spots, and where you actually need coverage. We ask about your routine—when you're home, when you're not, if you have kids or pets. That determines what equipment makes sense and where it goes.
Then we give you options. You'll see the difference between wireless and hardwired systems, what cameras cover, how smart locks work, and what monitoring plans look like. We explain costs upfront, including monthly monitoring, so there's no surprise fees later.
Installation usually happens within a few days. We mount cameras, place sensors, set up your control panel, and connect everything to your phone. Before we leave, we walk you through how to arm and disarm the system, how to get alerts, and what to do if something triggers. You'll also get our direct number—not a 1-800 line.
After that, your system is live. If an alarm goes off, our monitoring team gets notified immediately and will contact you and dispatch authorities if needed. You can also control everything from your phone: check cameras, lock doors, turn on lights, or disarm the system remotely.
Your alarm system installation includes door and window sensors, motion detectors, a control panel, and at least one security camera. Depending on your home and needs, we'll also recommend glass break sensors, smart locks, video doorbells, and smart lighting that integrates with your system.
Everything connects to your phone through an app. You get live camera feeds, real-time alerts, and remote control over locks and lights. If you're at work and a package gets delivered, you can watch it happen. If your kids get home from school, you'll know the second the front door opens.
In Settegast and across Houston, we're seeing more families add smart home integration because it makes the system easier to use. You can control your security with voice commands through Alexa or Google Assistant. Your cameras store footage in the cloud, so even if someone damages the equipment, you still have the recording.
Monitoring starts as low as $9.95 a month for self-monitoring, or you can upgrade to 24/7 professional monitoring where our team watches your system around the clock and contacts authorities if there's a real threat. Most of our Settegast customers choose professional monitoring because it qualifies them for the insurance discount and gives them peace of mind during work hours when break-ins are most common.
Installation costs depend on the size of your home and what equipment you need, but most Settegast homeowners spend between $400 and $1,200 for a complete system. That includes door and window sensors, at least one camera, a control panel, and professional installation.
Monthly monitoring runs between $9.95 for self-monitoring and $40 to $50 for full 24/7 professional monitoring. There are no activation fees or hidden charges when you work with us. We give you the total cost upfront, and you decide what fits your budget.
A lot of families don't realize their homeowner's insurance drops when they install a monitored security system. That discount can be 10% to 20% depending on your provider, which offsets the monthly monitoring cost. Over time, the system basically pays for itself while protecting your home and family.
Yes. Every system we install has battery backup that keeps it running during power outages. The backup typically lasts 24 hours or more, so even if a storm knocks out electricity, your alarm system stays armed and functional.
If your internet goes down, most modern systems have cellular backup built in. That means the system can still send alerts and communicate with the monitoring center even without Wi-Fi. You won't lose protection just because your router stops working.
We test both backups during installation to make sure everything works the way it should. Houston gets its share of storms and outages, so these features aren't optional—they're standard on every system we put in.
Most installations take between three and six hours depending on the size of your home and how many devices you're adding. A basic system with sensors and one or two cameras can be done in an afternoon. Larger homes with multiple cameras, smart locks, and integrated lighting take a bit longer.
We schedule installations based on your availability, and we'll give you a time window so you're not waiting around all day. Our techs show up on time, work efficiently, and clean up before they leave. Once everything's installed, we spend about 30 minutes walking you through how to use the system.
In most cases, we can get you scheduled within a few days of your consultation. If you need same-day service because of a specific concern or incident, let us know and we'll do everything we can to make it happen.
Yes. Every system we install connects to a mobile app that works on iPhone and Android. You can arm or disarm your system, check live camera feeds, lock or unlock smart doors, and get instant alerts whenever something triggers a sensor.
The app also lets you create custom rules. You can set your system to automatically arm at 10pm, turn on lights when motion is detected, or send you a notification when your kids get home from school. Everything's controlled from one app, so you're not juggling multiple logins or devices.
Remote access is one of the biggest reasons families upgrade to a modern alarm system. You're not tied to a keypad anymore—you have full control no matter where you are. And if you ever have trouble with the app or need to adjust settings, we walk you through it over the phone or come back out if needed.
If you have professional monitoring, our team gets an alert the second your alarm triggers. We'll try to reach you first using the contact numbers you provided. If you answer and confirm it's a false alarm, we'll stand down. If you don't answer, or if you confirm there's a real problem, we'll dispatch police or fire to your home immediately.
If you're on a self-monitoring plan, you get the alert directly on your phone and you decide whether to call authorities yourself. Either way, you'll know what's happening in real time. The cameras also start recording automatically when the alarm goes off, so you have footage of whatever triggered the system.
False alarms do happen—pets, open windows, user error. That's why we take time during installation to position sensors correctly and teach you how to use the system. If you're having repeated false alarms, we'll come back out and adjust the setup at no extra charge. The goal is a system that protects you without crying wolf.
Yes. Most insurance companies in Texas offer discounts between 10% and 20% when you install a monitored alarm system. The discount applies because you're statistically less likely to file a claim for theft or property damage when your home is protected and monitored.
The discount usually requires professional monitoring, not just self-monitoring. Your insurance provider will ask for proof that the system is active and monitored by a licensed company. We provide that documentation as part of your installation, and you submit it to your insurer to activate the discount.
For a typical Settegast homeowner paying $1,200 a year in insurance, a 15% discount saves you $180 annually. That's $15 a month, which covers a big chunk of your monitoring cost. Over the life of the system, that's real money back in your pocket while your home stays protected.
