Your home is protected around the clock, whether you're at work, asleep, or out of town. You can check in from your phone, get instant alerts if something's wrong, and know that trained operators are watching your property when you can't.
Most break-ins in Harris County happen between 10am and 3pm—right when you're at work or running errands. A monitored security alarm doesn't just scare off intruders. It contacts authorities immediately, cuts response time, and gives you a record of what happened.
You're not locked into a multi-year contract with a faceless corporation. You get a system built around how you actually live, installed by technicians who know South Main, and backed by a local team that picks up the phone when you call.
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 protecting South Main and the greater Houston area since 2008. We've installed and monitored systems for over 700 homes and businesses, and we're still here because we treat customers like neighbors, not account numbers.
We're 100% licensed and insured, and we've earned recognition like the Angie's List Super Service Award and Best of Home Advisor. But what really matters is that our customers know us by name, and we know their systems inside and out.
South Main families deal with real security concerns. You're close enough to downtown Houston to face urban crime trends, and property crime rates in the area make professional monitoring more than just a nice-to-have. We've seen what works here, and we build systems that match the risks you actually face.
From smart home security to 24/7 professional monitoring — discover the full range of solutions we offer to protect what matters most.

We start with a conversation about your home and your concerns. Not a sales pitch—a real walkthrough of what you're dealing with, where your vulnerabilities are, and what kind of system makes sense for your layout and budget.
Once you're ready to move forward, we schedule installation. Most systems go in within 24 to 48 hours. Our technicians mount sensors, cameras, and control panels exactly where they need to be, test everything on-site, and show you how to use it before they leave.
After installation, your system connects to our 24/7 monitoring center. If an alarm trips, our operators verify the alert and contact you immediately. If you don't respond or confirm it's a false alarm, we dispatch police or fire. You also get access to a mobile app that lets you arm, disarm, and check your system from anywhere.
If you already have an alarm system that's sitting inactive, we can often take it over and get it monitored without replacing all the equipment. That saves you thousands and gets you protected faster.
Every system we install includes door and window sensors, motion detectors, a control panel, and cellular communication that works even if your power or internet goes out. You're not dependent on Wi-Fi, which fails in 46% of smart home setups according to recent data.
You can add video doorbells, indoor and outdoor cameras, smart locks, and smart lighting. All of it integrates into one app so you're not juggling five different platforms. If you want full home automation, we can build that. If you just want solid intrusion detection, we do that too.
Our monitoring is live 24/7, handled by trained operators who know how to reach South Main emergency services. You're not getting an automated response or a call center overseas. When your alarm goes off, a real person evaluates it and takes action.
We also don't bury you in long-term contracts. You get flexible monitoring plans, transparent pricing, and the ability to adjust your system as your needs change. That's a big difference from the national companies that lock you in for three to five years and charge you penalties if you move or cancel.
Most installations happen within 24 to 48 hours of your approval. If you're in a rush—maybe you're moving into a new home or just had a break-in nearby—we can often get a crew out the same day or next day.
The actual installation takes a few hours depending on the size of your home and how many devices you're adding. A basic system with door sensors, motion detectors, and a control panel usually takes two to three hours. If you're adding cameras, smart locks, and other automation, plan for four to five.
We don't leave until everything's tested and you know how to use it. That includes walking you through the app, showing you how to arm and disarm the system, and making sure all your sensors are communicating properly.
In most cases, yes—we can take over and monitor your existing system without replacing everything. If the equipment is still functional and uses standard components, we'll connect it to our monitoring center and get it active again.
This is common with homes that have old ADT, Brinks, or other legacy systems that are no longer monitored. You're sitting on thousands of dollars worth of equipment that just needs a monitoring service to bring it back online.
We'll come out, assess what you have, and tell you honestly what can stay and what might need an upgrade. Sometimes a panel or communicator needs to be swapped, but the sensors and detectors usually stay. That saves you a lot of money compared to ripping everything out and starting over.
Our monitoring center gets the alert within seconds. An operator will try to reach you immediately using the contact numbers you provided—usually your cell phone first, then a backup number.
If you answer and confirm it's a false alarm, we log it and stand down. If you don't answer, or if you confirm it's a real emergency, we dispatch the appropriate authorities to your South Main address. That could be police for a break-in, fire department for smoke or carbon monoxide, or medical services if you have a panic button.
You'll also get a push notification on your phone the moment the alarm trips, so you can check your cameras and see what's happening in real time. A lot of customers catch package thieves, solicitors, or even family members who forgot the code this way.
You don't need a landline. Our systems use cellular communication as the primary connection, which is faster and more reliable than phone lines or internet.
Landlines can be cut by intruders, and internet connections go down all the time—especially during storms or power outages. Cellular stays live as long as the towers are up, and your system has a backup battery that keeps it running for 12 to 24 hours even if you lose power.
If you want to add internet as a secondary connection for faster video streaming, we can do that. But the core alarm signals—intrusion, fire, medical—always go out over cellular so there's no single point of failure.
Monitoring typically runs between $30 and $60 per month depending on what level of service you choose. Basic intrusion monitoring is on the lower end. If you add video storage, smart home control, and mobile app access, you're closer to the higher end.
We don't require long-term contracts, so you're not locked in for years like you are with the big national companies. You can adjust or cancel your monitoring plan if your situation changes, though most customers stay with us because the service works and the price is fair.
There's also an upfront cost for equipment and installation, but that varies based on the size of your home and what devices you're adding. We'll give you a clear quote before we do any work—no surprise fees or hidden charges after the fact.
Most insurance companies offer discounts for professionally monitored alarm systems, usually between 5% and 20% depending on your provider and coverage. That can add up to real savings over time, especially if you're paying $1,500 or more per year in premiums.
The discount typically requires proof that your system is monitored 24/7 by a licensed company. We provide that documentation as part of your service, and you just submit it to your insurance agent.
Some insurers also give additional discounts if you have fire and carbon monoxide monitoring, not just burglary protection. It's worth calling your agent and asking what qualifies, because the savings can offset a good chunk of your monthly monitoring cost.
