You're not looking for the cheapest system. You want one that works when someone's at your door at 2 a.m., or when you're two states away and your phone pings with a motion alert.
That's what a properly installed alarm system does. It gives you real-time alerts. It connects to your phone so you can check in from anywhere. And if something goes wrong, someone's notified immediately—not five minutes later when it's too late.
Crosby's crime rate sits higher than 68% of Texas cities. That's not fear-mongering, it's just the reality. Homes without security systems are three times more likely to get broken into. The difference between having a system and not having one isn't just equipment—it's whether you're an easy target or not.
A good security system doesn't just scare people off. It records what happened, alerts the right people, and gives you documentation if you need it. You get peace of mind, lower insurance premiums, and a home that actually feels secure.
Choose the security solution that fits your needs. All plans include 24/7 professional monitoring and local Houston-area support.
We've been installing and monitoring home security systems across the Houston area for over 15 years. We've protected more than 700 homes and businesses, and we're fully licensed and insured in Texas.
We're not a national call center. We're a family-owned company based right here in the Houston metro, and we know what Crosby homeowners deal with—hurricane season, property crime, and the need for systems that hold up in Gulf Coast weather. Our team has earned the Angie's List Super Service Award and Best of Home Advisor recognition because we show up, do the work right, and don't disappear after installation.
When you call, you talk to someone local. When you need service, we're there fast—often same day. That's the difference between working with a local company and getting lost in a 1-800 queue.

First, we come to your home and walk through it with you. We're looking at entry points, layout, and what matters most to you—whether that's cameras, motion sensors, smart locks, or all of the above. This isn't a sales pitch. It's a real conversation about what makes sense for your property.
Once we map out a plan, we give you a clear quote. No hidden fees, no pressure to add things you don't need. If you move forward, we schedule installation at a time that works for you.
Installation typically takes a few hours depending on the system size. We mount cameras, install door and window sensors, set up your control panel, and connect everything to your smartphone. Before we leave, we walk you through how it all works—how to arm and disarm, how to get alerts, how to pull up camera feeds.
After installation, your system is monitored 24/7. If an alarm goes off, our monitoring team gets notified and contacts you immediately. If needed, we coordinate with local law enforcement. You're also set up with app access so you can control and monitor everything remotely, whether you're at work or on vacation.
If you ever have questions or need service, you call us directly. We handle repairs, upgrades, and troubleshooting without transferring you around.
Our alarm systems include door and window sensors that trigger alerts the moment someone opens them. Motion detectors cover interior spaces and can differentiate between your dog and an actual intruder with the right setup. You get a central control panel that's easy to use, plus smartphone access so you can arm, disarm, and monitor from anywhere.
We install security cameras—indoor and outdoor—with high-definition video, night vision, and cloud or local storage options. Video doorbells let you see and talk to whoever's at your front door, even when you're not home. Smart locks give you keyless entry and the ability to lock or unlock doors remotely.
Everything integrates with Z-Wave smart home devices. That means your security system can work with your lights, thermostat, and voice assistants like Alexa or Google Assistant. You can set routines—lights turn on when motion is detected, or your system arms automatically when you leave.
Crosby homeowners also benefit from 24/7 professional monitoring. Our team watches your system around the clock and responds to alerts in real time. If you're in an area where storm damage or power outages are a concern, we install systems with battery backup so your security doesn't go offline when the power does.
And because we know Gulf Coast weather, we use equipment rated for heat, humidity, and the occasional hurricane. Your system is built to last, not fail when you need it most.
Installation costs vary based on what you need. A basic system with door sensors, a control panel, and monitoring might start around $500 to $800. If you want cameras, smart locks, video doorbells, and more sensors, you're looking at $1,500 to $3,000 or more depending on the size of your home and the equipment.
Monthly monitoring typically runs $20 to $50 depending on the level of service. Some companies lock you into long-term contracts, but we don't. You're not stuck paying for years if your needs change.
The upside is that most homeowners save 10% to 20% on their insurance premiums with a monitored alarm system. That can offset your monthly monitoring cost pretty quickly. We'll give you a clear quote upfront so there's no guessing.
You can install a DIY system, but there are trade-offs. DIY systems are cheaper upfront, but they're also easier to mess up. Sensors placed wrong won't trigger when they should. Cameras aimed at the wrong angle miss what matters. And if something doesn't work, you're troubleshooting it yourself or dealing with customer support that may or may not help.
Professional installation means the system is set up correctly from day one. We test everything before we leave. Cameras are positioned to cover entry points and blind spots. Sensors are placed where they'll actually detect intrusions. You're not guessing whether it's working—you know it is.
Plus, professional systems tend to be more robust. They're designed for reliability, not just convenience. If you're serious about security and want a system that works when it counts, professional installation is worth it.
Yes, if it's set up right. Most professionally installed systems include battery backup that keeps your alarm running for 24 hours or more during a power outage. That's critical in Crosby where storms can knock out power for extended periods.
For internet failures, many systems use cellular backup. If your Wi-Fi goes down, the system switches to a cellular connection so monitoring and alerts continue without interruption. You won't lose protection just because your internet drops.
DIY systems that rely solely on Wi-Fi and plug-in power are vulnerable during outages. If you lose power or internet, those systems go offline. That's a big risk if a storm is exactly when someone might try to break in. We build redundancy into our installations so your security doesn't disappear when conditions get rough.
When your alarm triggers, our monitoring center is notified within seconds. We'll attempt to contact you immediately using the phone numbers you provided. If you don't answer or if you confirm it's a real emergency, we contact local law enforcement right away.
Police response time in Crosby varies depending on where you are and what else is happening, but having a monitored system means law enforcement is notified faster than if you had to call yourself. Every second counts in an emergency.
You also get instant alerts on your phone, so even if you're not home, you know what's happening in real time. You can check your cameras, see what triggered the alarm, and communicate with monitoring or police as needed. Fast notification and fast response are the whole point of having a monitored system.
Yes. Every system we install includes smartphone access through an app. You can arm and disarm your system remotely, check the status of sensors, view live camera feeds, and get instant alerts when something triggers.
If you have smart locks, you can lock or unlock doors from anywhere. Video doorbells let you see and talk to visitors even when you're not home. You can also set up automation—like having your system arm automatically when you leave or lights turn on when motion is detected.
The app works on iOS and Android, and it's designed to be simple. You're not digging through complicated menus. Everything is straightforward so you can check in quickly and know your home is secure. Remote access is standard, not an expensive add-on.
You call us directly, and we handle it. We don't route you through a national call center or make you wait days for a technician. Most of the time, we can troubleshoot over the phone and get your system back online quickly.
If we need to come out, we schedule service fast—often same day depending on the issue. We've been doing this for over 15 years in the Houston area, so we know these systems inside and out. Repairs are straightforward, and we keep common parts in stock.
You're also covered if you need to upgrade or expand your system later. Want to add more cameras or sensors? We handle that too. The goal is to keep your system working reliably without hassle, and we're available when you need us.
