Home Security Systems in Texas: The New Homeowner's Guide

You just closed on a house in Texas. Congratulations and now the clock starts. Between the movers, the utility connections, and the mountain of paperwork, home security tends to slip to the back of the list, right until the first night in a house that isn't fully locked down.

We help people set up a new home every week, and the pattern is consistent: the households that treat security like a Day-One utility (same tier as electricity and internet) don't have that first-night jolt. The ones who wait usually pay more for a rushed install a month later, and sometimes learn the hard way that the previous owner's garage code is still active.

This guide is the version of that conversation we'd have with a friend moving into a new Texas home. It covers what home security systems in Texas actually look like in 2026, how to pick a system and a company without getting locked into a contract you'll regret, what it really costs, and the move-in safety checklist we run through with clients ourselves. Home security in Texas has a few local wrinkles that generic national guides skip weather, grid, permits, HOAs and we'll spend time on those. We'll use Plano and the broader DFW as a concrete local example because that's where our office sits, but the framework applies across the state.

What "Home Security" Actually Means in 2026

"Home security" used to mean an alarm panel by the front door, a couple of window sensors, and a landline connection to a monitoring center. That version still exists, but a modern system is closer to a small connected safety network one that handles far more than intrusion.

A well-designed home security system in Texas does three things in order:

• Prevents entry attempts by making your home look occupied and hardened (signage, lighting, cameras, smart locks).
• Detects problems fast not just break-ins, but smoke, carbon monoxide, water leaks, and freezing pipes, which matter more in Texas than most people expect.
• Responds through professional monitoring, notifications to your phone, or a mix of both.

The core stack most homes end up with looks like this:

• A hub or panel (the brain)
• Entry-point sensors on exterior doors, ground-floor windows, and the garage
• Interior motion sensors, ideally pet-immune if you have a dog or cat
• At least one outdoor camera and a video doorbell
• Environmental sensors smoke, CO, and, in Texas, a freeze or water-leak sensor near the water heater or under sinks
• Backup: a battery inside the panel and a cellular signal path so it works when Wi-Fi or power drops

That last part is easy to skip and expensive to skip. We'll come back to it.

Why Texas Changes the Home Security Equation

Most "how to pick a home security system" articles are written for a national audience. That's fine as a starting point, but a few things about living in Texas quietly shift the priorities.

The grid, and the weather

Texas runs on its own power grid through ERCOT. Most winters are calm, but you don't have to look far back to remember what happens when they aren't. A home security system that dies with the lights isn't much of a security system. In Texas we treat cellular backup and a real battery inside the panel as non-negotiable, not optional upgrades and we push clients hard on freeze and water-leak sensors because a burst pipe during a February cold snap is now a household planning event, not a freak accident.

Coastal homes face a different flavor of the same problem: hurricane season and outages tied to it. If you're closing on a place in Houston or along the Gulf, treat backup power and cellular monitoring as part of the security build, not a separate project.

Alarm permits and false-alarm ordinances

Most Texas cities regulate residential alarm systems. That usually means you have to register your system with the city, pay a small annual permit fee, and this is the part people miss you get a limited number of free false-alarm dispatches per year. After that, fines escalate.

Plano is a good example. The city requires you to register the alarm with the Police Department, there's an annual fee, and false-alarm charges kick in once you exceed the free responses in a calendar year. Exact numbers move around, so check the current Plano Police alarm permit page before you send in a check. Dallas, Fort Worth, Houston, San Antonio, and Austin all have their own versions of the same ordinance different fees, different free-response counts, same idea.

If your installer doesn't bring up the permit, that's a small red flag. The good ones handle it as part of the onboarding.

Deregulated everything

If you're new to Texas, you may not realize that most of the state has a deregulated retail energy market and deeply deregulated telecom. You'll be picking your own electricity provider, your own internet service, and your own security company often all in the same week. The order matters, because the security system is going to depend on the internet you choose, and a chunk of your smart-home options depend on both. That's why bundling the whole move-in electricity, internet, insurance, and security together is less of a marketing pitch and more of a scheduling problem worth solving on purpose.

HOA rules and neighborhood signage

Newer Plano, Frisco, McKinney, and Prosper neighborhoods tend to have HOAs, and some of them have surprisingly specific rules about yard signs and doorbell cameras facing public sidewalks. Before you plant six branded signs across the lawn or mount a floodlight camera at the property line, skim the HOA covenants. Nothing about security should trigger a violation letter in your third week in the house.

Types of Home Security Systems

Ask five different companies to describe your options and you'll get five different taxonomies. The one below is the simplest way to actually compare products.

Professional monitoring vs. self-monitoring

Professionally monitored systems connect your panel to a 24/7 monitoring center. When an alarm trips, a live person calls you, verifies whether it's real, and if it is dispatches police, fire, or EMS. Monthly cost for security monitoring at that tier typically sits in the $20–$60 range depending on features.

Self-monitored systems skip the central station. Alerts go straight to your phone, and it's on you to call 911. There's no monthly monitoring fee, and modern app experiences are surprisingly good, but you're the response layer. If you travel, sleep with your phone on Do Not Disturb, or don't want to be the person deciding whether a 3 a.m. glass-break alert is a real break-in or a raccoon, professional monitoring earns its cost.

There's also a growing middle option: optional-monitoring systems (SimpliSafe, Ring Alarm, Abode) that let you self-monitor for free and add professional monitoring month-to-month for $10–$30 without a contract. That flexibility is one of the biggest shifts in the market over the last few years.

Professional installation vs. DIY

DIY-friendly systems ship with peel-and-stick sensors, wireless components, and an app that walks you through the setup. Most people can install a starter kit in a weekend afternoon.

Professional installation is usually included with the big monitored providers (ADT, Vivint, Brinks) and always with local Texas-owned installers. You pay more, but a trained tech will place motion sensors and cameras in the spots that actually matter, wire in a dedicated backup battery, and make sure your system talks to the monitoring center before they leave the driveway.

Which is right depends on how much house you're securing. A townhouse with a couple of doors and a single-story footprint is a fine DIY project. A 3,500-square-foot two-story in a Plano cul-de-sac with a pool, side gate, and detached garage benefits from a pro walking the perimeter with you.

Wired vs. wireless

Almost every new residential installation in Texas is wireless at the sensor level, which is a good thing. Wireless sensors are easier to place, easier to move, and there's nothing for an intruder to cut on the outside of the house. Some cameras still get wired for power over Ethernet, and hardwired versions of most sensors still exist for people who want no batteries to change but for a typical new-homeowner install, wireless is the default.

If you're moving into a newer build in DFW that came with structured wiring in the walls, you have more options than most. A pro installer can piggyback on the existing runs for cameras and central hubs.

Contract vs. no-contract

The biggest financial trap in home security is a long monitoring contract signed on move-in day. Traditional providers have historically leaned on 36-month agreements; some still do. No-contract options have grown fast because customers stopped tolerating early-termination fees.

Rule of thumb: if a company is asking for anything more than 24 months, you want a serious equipment discount or free installation in return, and you want to read the cancellation section before you sign. The month-to-month monitoring model is now widely available and works fine for most households.

Here's the same comparison in table form:

What a Strong System Actually Includes

You don't need every camera and sensor on the market. You do need coverage in the right places.

• Every ground-floor exterior door front, back, side gate to a fenced yard, garage-to-house door. All get contact sensors. The garage-to-house door is the most-forgotten one.
• Ground-floor windows especially anything at the back of the house or shielded from the street.
• A video doorbell at the front. It also solves a lot of package-related complaints.
• At least one outdoor camera covering the driveway and one covering the backyard. Two-way audio matters more than megapixels.
• Interior motion sensors in the main hallway and any large open room. Pet-immune models handle dogs up to a certain weight check the spec sheet against your dog.
• Smoke and CO detectors integrated with the system so a fire alarm becomes a monitored event, not just an angry beep. In Texas, this pairs well with…
• A freeze sensor near the water heater and in the attic, and water-leak sensors under the kitchen sink, behind the washer, and near the water heater. The 2021 winter storm rewrote a lot of Texas homeowners' priority lists here.
• A glass-break sensor in rooms with large windows. Modern acoustic sensors cover a whole room.
• A cellular backup radio inside the panel, plus a battery inside the panel rated for at least 24 hours.

That's a substantial list, but a competent installer will map it in an afternoon. The point is that "a security system" isn't one product it's a layered stack. If a salesperson tries to sell you a panel and two door sensors and call it done, you're not getting a security system, you're getting a starter kit.

Smart Home Integration And Why Wi-Fi Comes First

Smart home integration sometimes marketed as home automation is the reason a modern security setup can do things that felt like science fiction a decade ago: unlock a smart deadbolt for a house cleaner during a specific two-hour window, cycle the porch light on when a delivery driver approaches, arm the system automatically when the last phone leaves the driveway.

The pieces that matter most for a new home in Texas:

• A voice assistant that talks to your panel. Alexa, Google Home, and Apple Home each work with most major systems now, but not all systems work with all three. Pick your assistant before you pick your panel if this matters to you.
• Smart locks on exterior doors. One-time codes for repairs, cleaners, and Airbnb-style stays are worth the upgrade on their own. Smart locks also let you retire the "hide-a-key under the mat" habit forever.
• Smart lighting for occupancy simulation while you travel. This is one of the most effective anti-burglary tools in the stack, and it's cheap.
• A smart thermostat tied into the freeze-sensor logic pushing the heat up automatically if attic temperature drops below a set threshold. This is a distinctly Texan use case.
• A smart garage-door opener. The garage is one of the most common entry points, and knowing whether it's open from anywhere is worth the $50–$100 device cost.

The catch is that all of that runs on your home's Wi-Fi. Cameras eat bandwidth. Smart devices bicker over the 2.4 GHz band. If you're moving into a two-story home and running the same consumer router your ISP handed you at signup, expect coverage gaps and dropouts and those gaps show up as missed camera events at exactly the wrong moment.

That's why we pair the security conversation with the internet conversation. A little planning around internet and cable setup for a new home the plan speed, where the modem sits, whether you need mesh nodes upstairs makes the difference between a security system that works and one that mostly works.

The New-Home Move-In Safety Checklist

This is the practical part. If you do nothing else from this guide, do this list, in order, in the first week.

1. Change or rekey every exterior lock before the first night. You have no idea how many copies of the old keys are floating around. A locksmith can rekey a standard house in an hour for under $200; a smart-lock swap works too.
2. Reset the garage door opener. Wipe any programmed remote codes, clear any HomeLink pairings in cars other than yours, and change the keypad PIN.
3. Test every smoke and CO detector. Replace batteries in anything that beeps, and swap the whole unit if it's more than ten years old. Texas doesn't play around with wildfire smoke drift or gas-appliance CO risk.
4. Locate the main water shutoff, the gas shutoff (if applicable), and the breaker panel. Photograph them. The first time you need to shut off water is not the time to be hunting for the valve.
5. Walk the exterior at night. Note dark corners, dead motion lights, and any landscaping that hides doors or windows. Trim aggressively. Motion-activated flood lighting at the driveway and back patio pays for itself in deterrence.
6. Book your security system install for before, or the same week as, move-in. Not two weeks after. Installers get booked out fast around big move-in months (May–August especially in DFW).
7. Register for your city's alarm permit as soon as the system is active. In Plano and most Texas cities, the permit is required and the fine schedule for unpermitted systems is steeper than the permit itself.
8. Set up your Wi-Fi properly before the cameras go in. If your ISP tech is coming, ask them to put the router centrally, not in a corner utility closet. Mesh nodes upstairs if it's a two-story build.
9. Save non-emergency numbers. Plano PD non-emergency, your HOA (if any), your neighbors, and your monitoring center. All in your phone, all labeled clearly.
10. Update your homeowners insurance with the address and system details. This is how you actually claim the security-system discount — not automatically, but by calling.
11. Change utility, banking, and delivery addresses. Related, but essential: mail forwarding buys you a window while you clean up subscriptions. Old mail with your name at the previous address is a mild identity-theft risk.
12. Resist the urge to broadcast the move on social media in real time. Post the moving-day pictures next week.

Print the list, tape it to the fridge, work through it. Every one of those takes under an hour except the exterior walk and the security install itself.

Best Home Security Companies in Texas By Category, Not Rank

You'll see plenty of "Top 5 best home security companies in Texas" listicles. Most of them are affiliate-driven. The more honest way to look at the market is by category, because the best home security company in Texas for a single-story townhome in Plano isn't the best fit for a 5,000-square-foot home in Southlake, and neither is the best fit for a rental in Dallas.

National monitored providers

Names you'll recognize: ADT, Vivint, Brinks Home, Frontpoint. These companies do professional installation, run their own monitoring centers, and cover most of Texas with a local dealer network. Strengths: proven monitoring, wide equipment catalog, and integration with most smart-home platforms. Trade-offs: they tend to push longer contracts, prices are less transparent, and the sales process can be aggressive. Good default if you want a big-name backstop and don't mind negotiating.

DIY-with-optional-monitoring providers

Names: SimpliSafe, Ring Alarm, Abode, Wyze Home Monitoring. You buy the equipment outright, install it yourself, and choose whether to add month-to-month professional monitoring. Strengths: transparent pricing, no long contracts, easy to move to your next home, strong app experiences. Trade-offs: you're responsible for installation quality, cameras and hardware are typically consumer-grade, and support is remote-only. A great fit for smaller homes and tech-comfortable owners.

Local Texas installers

Names vary by metro Smith Thompson and True Protection are two long-running examples in the DFW area, and every major Texas city has its own established local shops. Strengths: they walk your property, they know local ordinances by heart, and their pricing is often no-contract or short-contract. Trade-offs: coverage is regional, equipment ecosystems can be narrower, and quality between local shops varies more than with the nationals do the licensing check we cover below.

Insurance-carrier or utility-bundled options

Some homeowners insurance carriers, including State Farm and Farmers, offer discounted monitored security through partnerships. Some utility-adjacent concierge services (that's us, and a handful of others in Texas) work with security partners as part of a broader move-in setup. Strengths: single point of contact, sometimes real bundling discounts on your homeowners premium. Trade-offs: you're limited to the partner's equipment options.

None of those categories is objectively "best." The right question isn't which brand it's which category matches your home, your budget, and how involved you want to be.

How to Choose a Home Security Company in Texas

Once you've picked a category, use this checklist to filter the specific companies.

Verify licensing: In Texas, residential alarm system companies must be licensed by the Texas Department of Public Safety Private Security Board. Ask for the license number, and check it on the DPS website. It takes two minutes and it screens out the worst operators immediately.

Check monitoring center location and redundancy: A monitoring center in the U.S. is worth paying for. Two redundant centers is better. Ask where dispatchers sit and what the failover looks like.

Read the contract, especially the cancellation clause: Length, auto-renewal terms, early-termination fees, what happens if you move, and whether they cover a "move to a new address" credit. Get answers in writing.

Ask about false-alarm handling: How does the monitoring center verify an alarm before dispatching police? Two-way audio verification? Video verification? Some Texas cities require verified response now.

Get itemized pricing: Equipment cost, installation fee, monthly monitoring, activation fee, permit assistance. If they can't itemize, that's a signal.

Ask how they handle system failures: What's the SLA on a broken sensor? How fast can they get a tech out? Do they charge for service calls?

Look at how they handle your data: Where are camera recordings stored, who has access, how long are they retained, what's the process if you cancel service?

A company that answers all of those without hesitation is a company worth signing with. One that dodges any of them is worth crossing off.

What It Actually Costs

Home security pricing is opaque on purpose, so here's a realistic range for a new Texas home.

Equipment:

• DIY starter kit (SimpliSafe, Ring Alarm base tier): $200–$400
• Solid DIY kit with several cameras: $600–$1,200
• Professionally installed system, mid-range: $1,000–$2,500 including install
• High-end pro install with premium cameras and smart-home integration: $3,000–$8,000+

Monthly monitoring:

• Self-monitoring: $0–$5
• Basic professional monitoring: $20–$30
• Full-featured monitoring with cellular, video verification, smart-home features: $40–$60

Recurring city fees:

• Alarm permit fee: typically $30–$75 per year, varies by city
• False-alarm dispatches: usually 2–3 free per year, then escalating fees ($50–$300+ per incident depending on the city)

Insurance offset:

Most Texas homeowners carriers offer a discount for a monitored security system. The typical range is 5%–20% off your homeowners premium, depending on carrier and system features. On a $2,500 annual premium, that's $125–$500 back per year often enough to cover the monitoring fee.

You have to actually call your insurer to apply it. It doesn't happen automatically. A well-organized move-in coordinates this our guide on where the savings hide in home insurance covers the discount stacking in more depth.

Rough three-year picture for a mid-sized Plano home with a mid-range pro-installed monitored system:

• Equipment + install: $1,500
• Monitoring at $35/month × 36 months: $1,260
• Permit fees: $150
• Insurance discount applied at $200/year × 3: -$600
• Net three-year cost: roughly $2,310

That's about $64/month all-in. Cheaper than most people expect once the insurance offset lands.

Plano and DFW: A Concrete Local Snapshot

Since our office is in Plano and a big share of the homes we help set up sit in North Texas, a few DFW specifics worth calling out.

Plano's overall crime rate is low compared to the national average, but property crime package theft, garage break-ins, car burglaries in driveways is the category that shows up in local Nextdoor threads. Those are exactly the crimes visible cameras, motion lighting, and video doorbells discourage. When we spec Plano home security systems for clients, a visible security presence at the front of the house is almost always the first line item.

Newer subdivisions in Plano, Frisco, Prosper, and McKinney are often pre-wired for structured cabling, which makes a professional camera install cleaner. If you're closing on a new build, ask the builder whether structured wiring is included and where the drops are before you finalize the security design.

Plano's alarm permit ordinance is straightforward but active: you register with the police, pay an annual fee, and get a small number of free false-alarm responses before fees start. Most established Plano-area installers handle the paperwork for you at install time it's a fair question to ask up front.

Response times in Plano are strong by big-metro standards, but a verified alarm video verification or two-way audio confirmation moves your call up the priority queue everywhere in Texas. That's a system-choice consideration, not just a Plano one.

We built Utility Buddies partly because setting up a Plano home involves picking an electricity provider, an internet provider, a homeowners insurance carrier, and a security company inside the same short window. Handling all four in parallel (rather than one at a time over six weeks) is where most of the pain reduction lives.

Common Mistakes New Homeowners Make

We see these often enough that they deserve their own section.

• Waiting until after move-in to think about security: The first three weeks are when the house is most exposed new keys floating around, movers coming and going, neighbors not yet familiar with your comings and goings.
• Buying a system before checking Wi-Fi coverage: Six cameras and a mesh-less router in a two-story house is a support ticket waiting to happen.
• Skipping environmental sensors: Fire, water, and freeze sensors are the ones that pay for themselves. Insurance actuaries love them; adjust your priorities accordingly.
• Ignoring the alarm permit: It's a small fee. Skipping it costs more the first time the alarm trips.
• Signing a 60-month contract on the day of the sales visit: Sleep on it. Compare against a no-contract option. The good salespeople will still be there tomorrow.
• Broadcasting the move on social media in real time: Post-move photos, not move-in-progress ones. Especially if your privacy settings on Instagram are Public.
• Assuming the builder's included security package is complete: Builder-grade often means the panel and two door sensors. Read what's actually included.
• Not calling the insurer: The security discount doesn't apply itself.

Frequently Asked Questions

What is the best home security system for a new house in Texas?

There's no single answer, but there's a decent framework. For a smaller home or a first house, a DIY-with-optional-monitoring system (SimpliSafe, Ring Alarm, Abode) covers most needs with transparent pricing and no contract. For a larger home, a complex layout, or a household that would rather not troubleshoot cameras themselves, a professionally installed monitored system from ADT, Vivint, Brinks, or a licensed Texas installer is worth the higher cost. In every case, insist on cellular backup, a real battery in the panel, and environmental sensors (smoke, CO, freeze, water leak). Those three add-ons matter more than which brand is on the box.

How do I choose a home security company in Texas?

Start by picking a category (national monitored, DIY, local Texas installer, insurance-bundled) based on your home and how hands-on you want to be. Then filter the specific companies by verifying the Texas DPS Private Security Board license, checking monitoring center location and redundancy, reading the cancellation clause before signing, asking about false-alarm verification, and getting itemized pricing on equipment, install, monitoring, and any activation fees. Cross off any company that dodges those questions.

Do I need an alarm permit for a home security system in Plano?

Yes. Plano requires residential alarm systems to be registered with the police department, with a small annual fee. You get a limited number of free false-alarm dispatches per calendar year; after that, fines escalate. Every major Texas metro Dallas, Fort Worth, Houston, San Antonio, Austin has a similar ordinance with its own fee schedule. Ask your installer to handle the paperwork or link you to the current city page.

Will a home security system lower my Texas homeowners insurance?

Usually, yes. Most Texas homeowners insurance carriers offer a discount for a monitored home security system typically 5% to 20% off the annual premium, depending on the carrier and the system's features. Central-station monitoring, cellular backup, and smoke/CO integration tend to unlock the larger discounts. The catch: the discount is rarely applied automatically. You have to call your insurer, provide the monitoring certificate from your security company, and confirm the discount is on your policy.

Should I install security before I move in, or after?

Before or during, not after. The most exposed window is the first two to three weeks after closing, when locks may not be rekeyed yet, movers and contractors have access, and the neighborhood doesn't know you yet. Book the security install to happen before move-in day (if the house is empty) or within the first few days. Rekey the locks before the first night regardless that's the single highest-leverage security action for a new home.

Can I take my home security system with me if I move again?

Most DIY systems (SimpliSafe, Ring, Abode) move easily the sensors are wireless and the app follows the account. Professionally installed systems from ADT, Vivint, or Brinks are more variable: some offer "move" packages that transfer service to the new address, sometimes with an equipment credit. Ask about the mover policy before you sign, especially if you're likely to move again in the next few years.

The Easier Way to Set It All Up

Setting up a home security system is one of maybe four or five utility decisions competing for your attention the week you move in. Doing them one at a time turns a stressful week into a stressful six weeks.

That's the problem we solve at Utility Buddies. We're a Plano-based utility concierge working across Texas. We help you pick and connect electricity, internet, home and auto insurance, and home security in one call, at no cost to you (our partners pay us, not you). Our team knows the Texas providers, the local ordinances, the insurance discount stacking, and the schedule pressures around a move-in.

If you'd rather spend the week unpacking than on hold with providers, get in touch with our team and we'll take the setup off your plate security system and everything else that needs to be on before you sleep in the new house.
