First, we'll assess what you currently have. Most League City homes already have door and window sensors that work perfectly—they just need modern communication and monitoring. We'll test everything and show you exactly what we can use.
Next, we install a cellular communicator that connects your system directly to our monitoring center. No more relying on landlines that can be cut or phone services that go down during storms. Your system stays connected no matter what.
Finally, we set up your smartphone app so you can arm, disarm, and check your system from anywhere. We'll walk you through everything until you're completely comfortable using it. Most customers are surprised how simple and reliable their upgraded system becomes.
Our $17/month plan works with your existing alarm system—just adds professional monitoring and cellular communication. Perfect if you want reliable protection without replacing equipment that already works.
The $22/month option includes everything above plus smartphone control. You can arm and disarm your system remotely, get real-time alerts, and check status from anywhere. Most League City families love this convenience.
Our $27/month plan includes a complete modern touchscreen system with door sensors, motion detector, glass break sensor, and built-in camera. This works best for new homes or when you want to upgrade everything to the latest technology. League City's rapid growth means many residents are building new homes or extensively renovating, making this option increasingly popular for those wanting state-of-the-art protection.
Installation costs depend on what you currently have and which plan you choose. If your home already has an alarm system, our $17/month plan only requires a $139 one-time setup fee to add professional monitoring and cellular communication.
For smartphone control with existing equipment, it's still just $22/month with no additional installation fees. Our complete new system package costs $479 for equipment plus $27/month monitoring, but includes everything: touchscreen panel, door sensors, motion detector, glass break sensor, and built-in camera.
Unlike many companies, we don't hide costs in long-term contracts. You see exactly what you're paying upfront, and you can cancel anytime if you're not satisfied.
Most League City homeowners don't need to replace anything. If your home has door sensors, motion detectors, and a control panel that's less than 15 years old, we can usually work with what you have.
We'll test all your existing equipment during our initial visit and show you exactly what works. The main upgrade most systems need is cellular communication instead of relying on landline connections. This makes your system more reliable and faster to respond.
Only about 20% of our customers choose to upgrade to completely new equipment. The rest discover their existing system works great once it's properly monitored and connected to modern communication technology.
When your system triggers, our monitoring center receives the signal within seconds. Our trained operators immediately verify the alarm by calling your primary contact number, then your backup contacts if needed.
If we can't reach you, or if you confirm it's a real emergency, we dispatch local League City police, fire, or medical services depending on the type of alarm. This whole process typically takes less than two minutes from trigger to dispatch.
You'll also receive instant notifications on your smartphone if you have app control, so you know what's happening even if you're traveling. Many customers tell us this immediate response gives them confidence their home is truly protected, not just equipped with sensors that might or might not work.
No contracts required. You can cancel anytime without penalties or fees. This is different from most security companies that lock you into 3-5 year agreements with expensive early termination costs.
We earn your business every month by providing reliable service and quick response when you need it. If you're ever unsatisfied with our monitoring or customer service, simply call us and we'll cancel your service immediately.
Most of our League City customers have been with us for years, not because they have to be, but because they choose to stay. When you're not locked into a contract, you know the company has to keep earning your trust and satisfaction.
Cellular monitoring is significantly more reliable than landline connections. Phone lines can be cut by intruders, damaged by weather, or go down during power outages. Cellular signals continue working even when your electricity is out.
Our cellular communicators connect to multiple towers, so if one tower has issues, your system automatically switches to another. This redundancy means your monitoring stays active even during severe weather that might affect local cell towers.
League City's location near the coast makes this especially important during hurricane season. While landlines and internet often go down during storms, cellular monitoring typically maintains connection, ensuring your property stays protected when you need it most.
We service all of League City plus surrounding communities including Friendswood, Webster, Clear Lake, Kemah, and most of southeast Harris County. Our local presence means we can usually reach your location within an hour for service calls or installations.
Being based in the Greater Houston area since 2006, we know the neighborhoods, understand local concerns, and can respond quickly when you need support. This is a major advantage over national companies that might send technicians from across town or schedule service calls days in advance.
Our service area covers the entire League City school district boundaries plus adjacent communities where many of our customers work and live. If you're unsure whether we service your specific address, just call us and we'll confirm coverage for your location.
