Most alarm systems get installed based on a package deal, not what your property actually needs. That's why you end up with blind spots in your backyard, sensors that trip every time the dog walks by, or cameras pointed at nothing useful.
A properly designed security system covers the entry points that matter. Motion detectors go where someone would actually move through your space. Cameras face driveways, side gates, and back doors—not your fence line. You get alerts that mean something, not 12 notifications because a branch moved.
When your system is set up right, you're not wondering if it'll work. You're not dealing with false alarms or guessing whether the monitor is even on. It just runs. And if something does happen, the response is immediate—not three minutes later after you've already handled it yourself.
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 based in the Houston area. We've installed and monitored alarm systems for over 700 homes and businesses across Harris County, including right here in Mont Belvieu. We're licensed, insured, and A+ rated by the BBB—not because we paid for it, but because we show up and do the work right.
Mont Belvieu's grown fast. The population nearly doubled in the last decade, and with that growth comes new neighborhoods, more traffic, and unfortunately, more opportunity for break-ins. We've worked in this area long enough to know which streets get hit, what time of day matters, and how to set up a system that actually protects your property.
You're not getting a national call center or a sales pitch. You're getting a local team that knows the area, answers the phone, and shows up when you need service.
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 property. Not for a sales call—for an actual walkthrough. We look at your doors, windows, layout, and any weak points someone could use to get in. We ask what you're worried about and what you've noticed. Then we recommend what makes sense: door contacts, glass break sensors, motion detectors, cameras, smart locks—whatever fits.
Once you approve the plan, we schedule installation. Most systems go in within a day. We mount everything, run the wiring if needed, connect it to your Wi-Fi, and sync it with our 24/7 monitoring center. You'll get the app on your phone so you can arm, disarm, check cameras, and get alerts from anywhere.
Before we leave, we walk you through how it works. How to use the keypad. How to adjust settings. What triggers an alarm and what doesn't. If something goes off, our monitoring team gets notified instantly and will contact you, then dispatch if needed.
After that, we stay available. If you have questions, need adjustments, or want to add equipment later, we handle it. No phone trees. No transfers. Just call us.
Your system starts with the basics: door and window sensors on every entry point, a control panel, and at least one motion detector. From there, you can add cameras, video doorbells, smart locks, glass break detectors, smoke and carbon monoxide monitoring, or environmental sensors for flooding and temperature changes.
Everything connects to a central hub that communicates with our monitoring center. If your alarm goes off, we're notified in seconds—not minutes. Our team will try to reach you first. If we can't, or if you confirm there's a problem, we contact local authorities and send help. That monitoring runs around the clock, every day of the year.
Mont Belvieu sits near major highways and industrial areas, which means there's steady traffic and activity. A visible security system—especially cameras and alarm company signage—makes your property a harder target. Homes without systems are three times more likely to get broken into. The equipment matters, but so does the deterrent.
You'll also save on insurance. Most carriers drop your homeowner's premium by 5% to 20% when you have a professionally monitored system. That adds up over time and offsets part of your monitoring cost.
Equipment and installation typically run between $500 and $1,500 depending on the size of your property and what you need covered. A basic system for a smaller home with standard entry points will be on the lower end. Larger homes or businesses with multiple zones, cameras, and smart devices will cost more.
Monthly monitoring usually falls between $30 and $60. That covers 24/7 professional monitoring, app access, system maintenance support, and dispatch coordination if your alarm goes off. Some companies push long-term contracts, but we don't lock you into anything unreasonable. You're paying for a service that should work—if it doesn't, you shouldn't be stuck.
If you have an existing system that's outdated or not monitored, we can often upgrade or take over monitoring without replacing everything. That saves money and gets you back online faster.
Yes. Every system we install has battery backup that kicks in automatically if you lose power. Depending on the system size, that backup will keep everything running for 24 to 48 hours. The panel, sensors, and monitoring connection all stay active.
If your internet goes down, most modern systems have cellular backup built in. That means your alarm can still communicate with our monitoring center even if your Wi-Fi is out. You won't lose protection just because your router resets or your service drops.
We also test these backups during installation and periodically after that. If your battery is getting weak or your cellular signal is spotty, we'll let you know before it becomes a problem. You shouldn't have to wonder if your system will work when it matters most.
Yes. Once your system is installed, you'll download the app and log in with your account. From there, you can arm or disarm your system, check the status of every sensor, view live camera feeds, get alerts, and review recorded footage if you have cameras.
The app also lets you control smart locks, adjust lighting if it's integrated, and get notifications when specific doors open—useful if you want to know when your kids get home or if someone enters the garage. Everything updates in real time, so you're not waiting for the system to sync.
If you're not tech-savvy, that's fine. The app is straightforward, and we'll walk you through it during installation. You can also control everything from the keypad at home if you prefer. The phone is just an option, not a requirement.
Our monitoring team will call you immediately using the contact numbers you provided. If you answer and give your passcode, we'll cancel the dispatch and mark it as a false alarm. If you don't answer, or if you can't provide the passcode, we'll assume there's a problem and contact local authorities.
False alarms happen. Pets, open windows, user error—it's common, especially in the first few weeks. That's why we take time during installation to position sensors correctly and adjust sensitivity settings. We also give you a passcode that only you and trusted people know, so we can verify it's really you on the phone.
Most cities allow a couple of false alarms per year before they start fining you. After that, fees can range from $50 to $100 per false dispatch. We help you avoid that by setting up your system properly from the start and being available if you need adjustments.
DIY systems work for some people, but they come with trade-offs. You're responsible for mounting everything correctly, connecting it to your network, troubleshooting when something doesn't sync, and making sure sensors are positioned where they'll actually detect movement or entry. If you miss a spot or install a camera at the wrong angle, you won't know until it's too late.
Professional installation means the system is set up right the first time. We know where to place motion detectors so they cover the room without triggering on pets. We know how to angle cameras so you're not staring at a useless view of your driveway. We test everything before we leave, and if something stops working later, we come back and fix it.
You also get better monitoring. DIY systems usually rely on self-monitoring or app notifications, which means you're the one who has to see the alert and call the police. With professional monitoring, that happens automatically. If you're asleep, out of town, or your phone dies, we're still watching and responding.
Most residential installations take four to eight hours depending on the size of your home and how many devices you're adding. A basic system with door sensors, a motion detector, and a control panel can be done in half a day. Larger homes with multiple cameras, smart locks, and glass break sensors will take longer.
We schedule installations based on your availability and try to get everything done in one visit. If we need to run wiring through walls or attics, that adds time, but we'll let you know upfront. Wireless systems go faster since there's less physical setup involved.
Once everything is mounted and connected, we spend time testing each component and walking you through how to use it. You'll know how to arm the system, what each zone covers, how to check the app, and who to call if you need help. We don't leave until you're comfortable with how everything works.
