Professional Small Business Security Systems Installed Across Central Texas

Running a small business is challenging, but concerns about break-ins, theft, or vandalism should not add to your worries. At Centex Systems, LLC, we design and install security systems for small businesses throughout Central Texas, protecting your property, inventory, and staff. We serve retail shops, restaurants, offices, and service businesses in Temple, Waco, Killeen, Belton, and Harker Heights, providing customized alarm and camera solutions tailored to each location’s layout and risk profile. Whether you need to secure a single storefront or multiple sites, our licensed technicians deliver reliable, professional-grade security rather than repackaged consumer products.


A Centex Systems security solution typically includes a commercial-grade burglar alarm with door, window, and motion sensors, hardwired high-resolution security cameras, 24/7 monitoring from a Texas-based center, and mobile app access for remote oversight. Business owners in Salado, Georgetown, Lorena, Hewitt, Woodway, and across Central Texas trust our systems for real-time alerts, remote arming and disarming, and the assurance that their business is protected at all times, including after hours.


Choosing a small business security provider in Central Texas requires more than comparing prices; it means asking the right questions. How does the alarm communicate? What happens during a power outage? Who monitors your system overnight? Centex Systems addresses these concerns with solutions designed for real business needs. We use advanced cellular alarm communication that does not rely solely on your internet, battery backups to keep cameras operational during outages, and encrypted, jam-resistant technology to counter modern threats. We serve businesses in Bell County, McLennan County, and nearby areas including Jarrell, Gatesville, Hamilton, and Stephenville, delivering dependable security when it matters most.

  • Strongest 3-Year Warranty in the market.

    Unlike most security companies that only offer a 1-year warranty or less, Centex Systems includes a full 3-Year Parts & Labor Warranty at no extra cost. While competitors often charge monthly fees for “extended coverage,” we stand behind every installation with real long-term protection and accountability.

  • Stop Relying on Wi-Fi for Security, Hardwired is Better.

    Many security companies rely heavily on Wi-Fi cameras and wireless devices that can suffer from weak signals, low battery levels, interference, or disconnections. Centex Systems installs professionally hardwired security cameras whenever possible to provide faster performance, stronger stability, higher resolution, and more dependable protection when it matters most.

  • Security Without the Contract Trap.

    Many security companies lock customers into lengthy contracts with expensive cancellation penalties and contract buyouts. Centex Systems offers flexible month-to-month monitoring with no long-term contract or cancellation fees required. Centex Systems keeps cancellation simple and transparent. Customers who choose a 3-year monitoring agreement will receive an installation discount.

  • Emergency Backup Power Protection

    Most camera systems stop recording the moment power is lost. That is why Centex Systems offers battery backup for camera system installation. Backup power can help keep your cameras recording during power outages or if criminals cut power to the building.

  • Criminals Look for Easy Targets, Don’t Be One.

    Many low-cost or DIY alarm systems rely on basic wireless technology and internet-only communication that can be vulnerable to interference, outages, or inexpensive hacking devices purchased on Amazon. That is why Centex Systems offers advanced, encrypted, and jam-resistant technology, such as quality sensors and cellular alarm communication, to provide more secure and reliable protection against modern security threats.

  • State Licensed Technicians. Professionally Trained.

    Centex Systems technicians are licensed through the Texas Department of Public Safety and complete 40+ hours of initial classroom instruction, hands-on field training, and background checks before working independently. Because a security system is only as good as the people installing it.

  • We Don’t Just Install It. We Show You How to Use It.

    A security system only helps if you know how to use it. After installation, Centex technicians walk customers through their system step-by-step, including arming, disarming, mobile app features, alerts, and basic troubleshooting. On average, our technicians spend about 45 minutes after each installation training customers and answering questions. We do not leave until you are comfortable using your system.

  • We Treat Your Property Like Our Own, No Shortcuts.

    We treat your home or business with respect throughout the installation process and clean up thoroughly before leaving the job site. Every installation also goes through a 180-point technician checklist to help ensure the system is installed properly, tested, and functioning correctly before completion.

Professional installation by licensed technicians

Your installation is handled entirely by licensed, background-checked Centex technicians who treat your business with care. We work efficiently to minimize disruption to your operations and follow a strict 180-point technician checklist to verify every component is installed correctly, tested thoroughly, and fully operational before we wrap up.

Personalized training & ongoing support

Before we leave, your technician spends about 45 minutes walking you and your staff through the entire system; how to arm and disarm, use the mobile app, review camera footage, manage user codes, and handle everyday questions. We don't consider the job done until you're confident and in control. And if anything comes up later, we're just a call away.

Frequently Asked Questions

  • What does a home security system from Centex Systems include?

    A standard home security system installation from Centex Systems includes a control panel, door and window sensors, motion detectors, a keypad, a siren, and cellular monitoring communication. Depending on your home's size and needs, we may also include glass break sensors, security cameras, smart locks, or additional sensors. Every system is customized; we don't do one-size-fits-all.

  • Do I need Wi-Fi for my home security system to work?

    No. Centex Systems installs alarm systems that use cellular communication as the primary signal path, so your system doesn't rely solely on your home's internet or Wi-Fi. This is an important distinction. Many cheaper systems only communicate over Wi-Fi, so a simple router reset or internet outage could leave your home unmonitored.

  • Is a long-term contract required for monitoring?

    No. Centex Systems offers flexible month-to-month monitoring with no long-term contract or cancellation fees. Customers who choose a 3-year monitoring agreement receive a $300 installation discount and can cancel anytime by repaying that $300 discount; no penalties or contract buyouts.

  • How long does a home security system installation take?

    Most residential installations are completed in one day. After installation, your Centex technician will spend about 45 minutes walking you through your system, including how to arm and disarm it, use the mobile app, check camera footage, and handle basic troubleshooting. We don't leave until you're fully comfortable.

    Centex Systems installs home security systems throughout Central Texas, including Temple, Waco, Killeen, Belton, Harker Heights, Salado, Georgetown, Jarrell, Lorena, Hewitt, Woodway, Gatesville, Hamilton, and Stephenville. Not sure if we cover your area? Give us a call; we're happy to help.
