Most people think an alarm just makes noise. That's only half of it. Professional security monitoring means someone's watching your system every hour of the day, ready to contact authorities the second something's wrong.
You're not relying on a neighbor to hear it. You're not hoping you'll get a notification in time. When motion triggers at 2 a.m. or a door sensor trips while you're at work, a trained operator sees it immediately and takes action.
In Denver Harbor and Port Houston, where over 18,000 burglaries happen across Harris County every year, that response time matters. Most break-ins occur between 10 a.m. and 3 p.m. when you're not home. A monitored system doesn't just scare someone off—it gets help on the way before they're gone.
You get to check your phone from anywhere and see what's happening. You get alerts that matter. And if something's actually wrong, you're not the only one dealing with it.
Choose the security solution that fits your needs. All plans include 24/7 professional monitoring and local Houston-area support.

First, we come to your property and walk through it with you. We're looking at entry points, layout, and what matters most to you—whether that's doors, windows, motion detection, cameras, or all of the above.
Once we agree on a system, we install it the same day in most cases. Everything gets tested before we leave. You'll know how to arm it, disarm it, and check it from your phone. We don't leave until you're comfortable.
After that, your system connects to our 24/7 monitoring center. Every sensor, camera, and detector is live. If something triggers, our team sees it in real time and follows your instructions—call you first, contact authorities, or both. You're in control of how we respond.
You can also log in anytime to check camera feeds, arm or disarm remotely, or review activity. If you have questions or need adjustments, you call us directly. No phone trees. No waiting days for a callback.
Your system can include door and window sensors, motion detectors, glass break sensors, video doorbells, indoor and outdoor cameras, smart locks, and environmental monitors for fire, carbon monoxide, and flooding. Everything's wireless unless you prefer hardwired, and it all integrates with your phone.
Monitoring starts at $17 a month with no long-term contract. That covers around-the-clock professional monitoring, mobile app access, and technical support whenever you need it. If you want video storage, smart home integration, or additional cameras, we can add that.
In Denver Harbor and Port Houston, flooding is a real risk—54% of properties face severe flood risk in the next 30 years. Environmental sensors can alert you to water intrusion before it becomes a bigger problem, and monitored fire alarms mean help's on the way even if you're not home to hear it.
We're also licensed and insured, so you're covered if anything goes wrong during installation or service. And because we're local, we can get to you faster than most companies when you need us.
When your alarm triggers, our monitoring center sees it within seconds. An operator immediately reviews what sensor was tripped and follows your emergency contact protocol.
If it's a burglary alarm, we'll try to reach you first to confirm whether it's a false alarm. If we can't reach you or you confirm it's real, we contact local authorities right away and stay on the line until they're dispatched. The whole process typically takes under a minute from the time your alarm goes off.
For fire or carbon monoxide alarms, we dispatch emergency services immediately without waiting for confirmation. Every second counts in those situations, and we're trained to act fast.
Not always. A lot of homes in the Houston area already have alarm systems installed—they just aren't connected to a monitoring service.
We can evaluate your current equipment and let you know if it's compatible with our monitoring platform. In many cases, we can activate and monitor what's already there without replacing anything. If your system is outdated or incompatible, we'll explain what needs upgrading and give you options that fit your budget.
The goal isn't to sell you a brand-new system if you don't need one. It's to get you protected as affordably and quickly as possible. Sometimes that means working with what you've got.
Yes. Every system we install includes mobile app access so you can arm, disarm, and monitor from anywhere with cell service.
You'll get real-time alerts when doors open, motion is detected, or alarms trigger. If you have cameras, you can pull up live feeds or review recorded footage right from your phone. You can also control smart locks, check sensor status, and adjust settings without calling us.
It's especially useful when you're traveling, at work during the day, or just want to check in on your property. You're never locked out of knowing what's happening at home, and you don't need to be there to take action.
Your system stays active. Most modern alarm systems include battery backup that keeps sensors and the control panel running for 24 hours or more without power.
For connectivity, systems use cellular backup if your internet goes down. That means even if your Wi-Fi is out, your alarm can still communicate with our monitoring center and send you alerts. You won't lose coverage just because of a storm or service outage.
We test backup systems during installation to make sure everything works as expected. If your battery ever gets low, you'll receive a notification so you can replace it before it becomes a problem.
Our monitoring plans start at $17 per month with no contract. That includes 24/7 professional monitoring, mobile app access, and customer support.
If you want video recording, smart home integration, or additional features, pricing adjusts based on what you add. We'll walk you through options during your consultation so you know exactly what you're paying for and why.
There are no hidden fees, and you're not locked into a multi-year agreement. If your needs change or you're not happy with the service, you're free to cancel. We'd rather earn your business every month than trap you in a contract.
It significantly reduces the chance. Homes without security systems are 300% more likely to be broken into, and about 60% of burglars say they'll move on to another target if they see an alarm system.
The system won't physically stop someone, but it does two things: it makes your home less appealing to criminals, and it ensures a fast response if someone tries anyway. Most burglars want to get in and out in under 10 minutes. A loud alarm and a monitored response cuts that time down and increases their risk of getting caught.
In Harris County, where burglary rates are high and many happen during the day when people are at work, a monitored system gives you coverage when you're most vulnerable. It's not a guarantee, but it's one of the most effective deterrents available.
