You check the locks twice before bed. You worry when packages sit on the porch. You've heard the stats about Houston crime, and you know Greater OST / South Union isn't immune—your chance of property crime here is 1 in 22.
A security alarm changes that math. You get alerts on your phone the moment something's wrong. Professional monitors call police faster than you ever could. Your family feels safe, and you stop lying awake wondering if that sound was just the house settling.
The difference isn't just equipment—it's knowing someone qualified is watching when you can't. That's what 24/7 monitoring actually gives you. Homes without security systems are 300% more likely to get broken into, and 83% of burglars told researchers they'd avoid a house with visible alarms entirely.

First, we'll assess what you already have. Many Houston homeowners discover their existing alarm system just needs activation and monitoring—no expensive replacement required. If you need new equipment, we'll walk you through what actually makes sense for your home, not what makes us the most money.
Installation happens on your schedule, often the same day you call. We mount sensors on doors and windows, place motion detectors in key areas, and set up your control panel where you can reach it easily. If you want cameras, smart locks, or video doorbells, we integrate those too.
Before we leave, you'll know how to arm and disarm your system, what each alert means, and how to use the mobile app. We don't hand you a manual and disappear. Most installations finish in a few hours, and you're protected that same night.
After that, our monitoring center watches your home around the clock. If your alarm trips, they verify the threat and dispatch police or fire if needed. You get a text or call within seconds. No guessing, no delays.
Every system we install includes door and window sensors, at least one motion detector, a control panel, and a cellular communicator that works even if someone cuts your phone line. You're not buying a one-size-fits-all package—we customize based on your home's layout and what you're actually worried about.
Want cameras watching your driveway? Done. Need a panic button by the bed? We add it. Worried about fire or carbon monoxide? Those sensors integrate into the same system, and our monitors respond to those emergencies too. The security systems we offer detect intruders, fires, gas leaks, and other threats that matter in Greater OST / South Union homes.
Here's what sets us apart: our $17/month monitoring plan works with existing systems. We add the cellular communicator and monitoring service, often saving you thousands compared to companies that insist on full system replacement. And we've never required a contract—not since 1978. We keep you with service, not paperwork.
Smart home integration means you control everything from your phone. Lock doors remotely, check camera feeds, get alerts when your kids get home from school. It all connects through one app, and we'll show you how to use it before we leave.
Most installations happen within 24 to 48 hours of your call, and we often install the same day if you need it urgently. The actual installation takes a few hours depending on your home's size and how many sensors you want.
We're not a national company juggling hundreds of appointments across multiple states. We're local to Houston, which means we can move fast when you need us. If someone tried breaking in last week or you're leaving town tomorrow, call us in the morning and there's a good chance we'll have you protected by evening.
The process is straightforward: we assess your home, install the equipment, connect everything to our monitoring center, and teach you how to use the system. You're protected the moment we finish, not after some waiting period or activation delay.
Self-monitoring sounds appealing until you think through what actually happens during an emergency. You get an alert at 2 a.m.—now what? You're groggy, your phone's across the room, and you have to decide if it's real or a false alarm. Then you have to call 911 yourself, explain the situation, and hope they prioritize your call.
Professional monitoring means trained operators see the alert instantly, verify what's happening, and dispatch police or fire while you're still reaching for your phone. They know your address, your system layout, and your emergency contacts. Response time matters—especially in situations where every minute counts.
Our monitoring costs $17 to $35 per month depending on your system. That's less than most families spend on streaming services, and it's covering you 24/7 whether you're asleep, at work, or out of town. The University of North Carolina found that burglars specifically avoid homes with professional monitoring because they know police response is faster and more certain.
Every system we install includes battery backup that keeps your alarm running for 24 hours without power. That covers you during Houston's storms and outages, which happen often enough that backup power isn't optional—it's standard.
For communication, we use cellular connections, not phone lines. Even if someone cuts your landline or your internet goes down, your alarm still reaches our monitoring center through the cell network. Burglars used to disable alarms by cutting phone lines before breaking in. That doesn't work anymore with cellular communicators.
You don't need to do anything special to maintain this protection. The system tests itself daily and alerts us if something's wrong with the battery or cellular connection. We'll call you to schedule a fix before it becomes a problem. This is basic stuff that every alarm should have, but plenty of older systems in Greater OST / South Union are still running on outdated technology that leaves gaps.
Yes, in most cases. Many Houston homes have alarm equipment that's perfectly functional but hasn't been monitored in years. The previous owner stopped paying for service, or the monitoring company went out of business, and the system's been sitting dormant ever since.
We'll assess what you have during our initial visit. If the sensors and panel are in decent shape, we can reactivate the system, add a cellular communicator, and connect it to our monitoring center. You're paying for new monitoring service, not replacing equipment that already works. This typically costs a fraction of a full system replacement.
If your existing equipment is too old or incompatible with modern monitoring, we'll tell you straight. But we've reactivated systems that are 10 or 15 years old without issue. The sensors don't wear out quickly—they're just sitting there waiting for someone to turn the system back on. Our $17/month plan exists specifically for this situation, and it's saved Houston homeowners thousands compared to companies that insist everything needs replacing.
If you're locked into a long-term contract paying more than $40 per month for basic monitoring, you're probably overpaying. The actual cost of professional monitoring hasn't changed much in years—what's changed is how many companies bury you in contracts and fees.
Our monitoring runs $17 to $35 per month with no contract. You're getting the same UL-listed monitoring center, the same police and fire dispatch, the same 24/7 coverage as companies charging twice that. The difference is we're not spending millions on national advertising or paying shareholders. We're a local family business keeping costs reasonable.
Here's what to watch for: activation fees, installation fees, equipment fees, contract buyout fees. Some companies advertise low monthly rates but hit you with $500 in upfront costs. We charge for installation labor and equipment, but we're transparent about it from the start. And if you're unhappy with our service, you can cancel anytime—we're confident you won't need to.
It stops most of them before they try. The University of North Carolina surveyed convicted burglars and found that 83% would avoid homes with visible security systems, while 60% would choose a different neighborhood entirely if they saw extensive security measures. Criminals want easy targets, and alarms make your home harder than your neighbor's.
If someone does try breaking in, the alarm does two things: it makes noise, and it calls for help. The siren alone sends most burglars running—they know they have maybe 90 seconds before police arrive, and that's not enough time to find valuables and escape. Our monitoring center is already dispatching police while the burglar's still figuring out which way to run.
The statistics back this up. Homes without security systems are 300% more likely to be burglarized. That's not a small difference—it's the gap between being a target and being passed over. Nearly half of all violent crimes happen at residences, and most burglaries in Greater OST / South Union occur during daytime hours when homes are empty. An alarm protects you whether you're there or not.
