Your alarm detects motion or an open door. Within seconds, our monitoring center gets the signal and starts calling you. If you don't answer or confirm it's a false alarm, we're already dispatching police to your address.
That's the difference between a system that beeps and one that actually protects. You're not scrambling to check your phone or call 911 yourself. The response is already in motion.
In Northside and Northline, where property crime rates sit higher than most Houston neighborhoods, that speed matters. Burglars spend an average of 8-12 minutes inside a home. Professional monitoring cuts that window down before they get comfortable. You get real-time alerts on your phone, recorded footage if you have cameras, and the peace of mind that someone's watching even when you're in a meeting or on a plane.
Choose the security solution that fits your needs. All plans include 24/7 professional monitoring and local Houston-area support.

You call or fill out a form. We schedule a time to come out and walk through your home or business. We're not there to sell you the most expensive package—we're there to figure out what actually makes sense for your layout, your routine, and your budget.
We'll show you where sensors should go, explain how the system works, and answer your questions in plain language. If you already have equipment from another company, we'll tell you whether we can use it or if it needs replacing. No upselling, no pressure.
Once you're ready, we schedule the install. Most jobs get done the same day or within 48 hours. We mount the panel, place door and window sensors, set up motion detectors, connect cameras if you want them, and sync everything to your phone. Before we leave, we walk you through how to arm it, disarm it, and what to do if it goes off. You'll have our number, and we'll have yours.
Every system we install includes door and window sensors, at least one motion detector, a control panel, and a keypad. You can add glass break sensors, security cameras, video doorbells, smart locks, and smart lighting depending on what you need. Everything connects to an app so you can check status, arm or disarm remotely, and get alerts in real time.
Monitoring starts at $17 a month with no long-term contract. That includes 24/7 professional monitoring, cellular backup if your internet goes down, and battery backup if the power cuts out. If your alarm trips, our monitoring team calls you first, then dispatches help if needed.
In Northside and Northline, we see a lot of homes that were built in the 70s and 80s. Older construction sometimes means fewer pre-wired options, but wireless systems work just as well and install cleaner. We also work with a lot of small business owners who need after-hours monitoring for break-ins but don't want to pay commercial rates. We price fairly and don't bury fees in the fine print.
If you've got an existing system from ADT, Vivint, or another company, we can usually take it over and monitor it without replacing everything. That saves you thousands and keeps your house from looking like a construction zone.
Installation typically runs around $400 for a standard home system, though it varies depending on the size of your home and how many entry points you want covered. That usually includes a control panel, keypad, door/window sensors, and at least one motion detector.
If you want cameras, smart locks, or video doorbells, that adds to the upfront cost but gives you more control and visibility. Monthly monitoring starts at $17 with no contract, so you're not locked into years of payments. Some national companies advertise free installation, but they make it back by locking you into 3-5 year contracts at higher monthly rates.
We don't play that game. You pay a fair price upfront, and you're free to cancel monitoring anytime if you're not happy. Most people don't, because the service works and we're easy to reach when something needs adjusting.
Yes, in most cases. If you've got an older system from ADT, Vivint, Brinks, or another provider, we can usually take over monitoring without replacing all your equipment. We'll come out, check the panel and sensors, and let you know what's compatible.
Sometimes the panel needs a new communicator to connect with our monitoring center, but that's a small fix compared to ripping everything out and starting over. You keep your existing sensors and keypads, we handle the backend, and you start saving on monthly fees.
The exception is if your system is so old that parts are no longer supported or if the previous company installed proprietary equipment that won't talk to anything else. In that case, we'll give you an honest assessment and a quote for a new system. Either way, you'll know where you stand before we do any work.
Our monitoring center gets the signal within seconds of your alarm triggering. We immediately try calling you at your primary number, then your backup contacts if you don't answer. If no one confirms it's a false alarm, we dispatch police or fire depending on the type of alert.
The whole process takes less than two minutes from alarm to dispatch. Compare that to you getting an alert on your phone, trying to check your camera, then calling 911 yourself—that's at least five minutes, and you're doing it while panicking or in the middle of something else.
Professional monitoring removes that burden. You still get notified on your app, but the response is already happening whether you're available or not. In North Houston, where response times can vary depending on what else is happening, every minute counts. Monitored systems also get prioritized by police because they know it's been verified by a third party, not just a neighbor hearing something.
An alarm system will alert you and dispatch help when someone breaks in. Cameras let you see what's happening in real time and give you recorded evidence after the fact. Most people in Northside and Northline are adding cameras now because they want eyes on their property, not just an alert after someone's already inside.
Video doorbells are especially popular because you can see who's at the door before you open it, and you've got footage if someone's checking doors during the day. Outdoor cameras covering your driveway and backyard add another layer, especially if you've got equipment, tools, or bikes that are easy targets.
That said, if budget's tight, start with the alarm system and add cameras later. The alarm is what actually stops a break-in or gets police there fast. Cameras are the bonus that gives you visibility and evidence. We can install both at once or phase it in—whatever makes sense for your situation.
Your system keeps working. Every alarm system we install has battery backup that kicks in automatically when the power cuts. That'll keep your system running for 24 hours or more depending on the battery size.
We also use cellular backup for the monitoring connection, so even if your internet goes down, the system still communicates with our monitoring center over a cell signal. You won't get app notifications if your phone's not connected to data, but the monitoring center still gets alerts and can dispatch help.
This matters in Houston, where storms knock out power and internet regularly. A system that goes dark the second the lights go out isn't protecting you when you need it most. Ours stays live, keeps monitoring, and keeps you covered until everything's back online.
Most residential installs take 3-4 hours depending on the size of your home and how many devices you're adding. We're usually in and out the same day. If you've got a larger property or want a more complex setup with multiple cameras and smart home integration, it might take a full day.
We schedule installations based on your availability, and we'll give you a realistic time window when we book it. We're not the company that says "sometime between 8am and 5pm" and shows up at 4:30. We show up when we say we will, and if something changes, we call ahead.
After install, we walk you through everything before we leave—how to arm and disarm, how to use the app, what each sensor does, and what to do if you get a false alarm. You'll have our direct number, and if you forget something or need help later, you can call us. We don't route you through a 1-800 number where you're talking to someone three states away reading a script.
