Security Designed for Jarrell and the Surrounding Area

Jarrell is a growing community in Williamson County, located along I-35 between Georgetown and Temple. It offers the character of a Central Texas town, with residential neighborhoods, rural acreage, and working farms, and is increasingly attractive to families and commuters seeking space and affordability near the Austin-Round Rock metro area.



That mix of rural character and growth creates unique security needs. Properties are more spread out, lots are larger, and emergency response times are often longer than in more densely populated areas. A reliable security system that communicates independently of your internet connection and provides immediate alerts is especially important here, in semi-rural Central Texas. We design systems tailored to your specific property, not a standard package for a subdivision in a bigger city.

Hardwired Cameras Built for Larger Properties

Rural and semi-rural properties pose challenges that wireless cameras cannot effectively address. Greater distances between homes, outbuildings, barns, driveways, and gates often prevent Wi-Fi signals from reaching key areas. Battery drain, signal interference, and connection dropouts can make wireless systems unreliable in these settings.


Centex Systems installs professionally hardwired security cameras to deliver higher resolution, stronger performance, and consistent reliability, regardless of property size or distance from the router. For larger Jarrell properties, we design camera layouts to cover main entry points, outbuildings, driveways, and perimeter areas, using wiring built to withstand outdoor Texas conditions.



We also offer battery backup for camera systems, so your cameras continue recording even when the power goes out. In a rural setting where power outages can last longer and occur with less warning, backup power is not just a nice feature; it is a meaningful layer of protection.

Alarm Systems That Work Even When the Internet Does Not

In areas like Jarrell, internet connectivity is often less reliable than in larger cities. Many homeowners use satellite, fixed wireless, or slower broadband connections. Most basic and DIY alarm systems depend on your home's internet to communicate with a monitoring center, so if your connection drops, your alarm cannot call for help.


Centex Systems installs encrypted, cellular-based alarm systems that operate independently of your home internet. Whether your Wi-Fi is down, the power is out, or someone attempts to disrupt the signal, your alarm remains connected, and your monitoring center stays informed.


When your alarm activates, it contacts a Texas-based, UL-listed monitoring center, not an overseas call center unfamiliar with Williamson County. Our team understands the area and coordinates quickly with local emergency services, ensuring prompt response when it matters most.

Home Security Camera Systems

Jarrell’s combination of residential lots, rural acreage, and homes set back from the road makes professionally hardwired camera coverage essential.

Home Wi-Fi and Network Installation

Many Jarrell residents work from home or rely on home networks for school, streaming, and daily connectivity, often with less-than-ideal internet infrastructure. Professional Wi-Fi installation and structured cabling maximize your connection’s performance, providing faster speeds, better coverage, and fewer dropouts throughout the day.

Frequently Asked Questions

  • I have a larger rural property outside of Jarrell with a house, a shop, and a barn. Can you cover all of those structures?

    Yes, and this is exactly the kind of project we design for. We assess the full layout of your property and build a camera and alarm plan that covers your main residence, outbuildings, driveways, and any other areas you want monitored. For larger properties, hardwired cameras are especially important because Wi-Fi signals rarely reach outbuildings reliably — we run the wiring to get you real coverage where you actually need it.

  • My internet connection out here is not great. Will a security system even work reliably on my property?

    Yes. This is one of the most important reasons to choose a cellular-based alarm system rather than an internet-dependent one. Our alarm systems communicate via the cellular network, completely independent of your home broadband or Wi-Fi. Your security monitoring works whether your internet is fast, slow, or completely down. For cameras, we design systems that store footage locally on a recorder at your property, so you are not dependent on cloud uploads through a slow connection.

  • Is Jarrell within your service area, even though it is farther from Temple?

    Absolutely. Jarrell is part of our Central Texas service area, and we regularly work with homeowners and property owners throughout Williamson County and the I-35 corridor between Georgetown and Belton. Distance is not a barrier; we come to you.

  • How do I know the technician coming to my property is trustworthy?

    Every Centex Systems technician is licensed through the Texas Department of Public Safety, has passed a criminal background check, and has completed more than 40 hours of training before working on their own. We understand that inviting someone onto a rural property requires a higher level of trust, and we take that seriously. Our technicians are professional, respectful, and fully accountable.

  • What is included in the 3-year warranty and how do I use it if I have a problem?

    Our 3-Year Parts and Labor Warranty covers any equipment failure or issue related to the installation within three years of your install date. If something stops working correctly, you contact us, we schedule a service visit, and we repair or replace the affected components at no charge, parts and labor included. There is no monthly fee to keep the warranty active, and there is no complicated process to go through. We come out and fix it. That is the whole deal.
