We've done the hands-on testing and local research to help you decide. 

Is Your St. Louis Home Really Secure? What I Learned After Testing 5 Professional Security Installations

Have you ever wondered if your home security system is actually protecting you—or just giving you a false sense of security? After having five different systems professionally installed in the same house, I discovered some shocking truths about what works and what's just marketing hype.

The Gateway to Security in the Gateway City

St. Louis, with its vibrant cultural scene and iconic Gateway Arch, represents the best of Midwestern hospitality. But beneath the charm lies a sobering reality: the city faces significant security challenges that residents can't afford to ignore.

As someone who's spent the last year testing every major security system in our St. Louis test facility, I've seen firsthand how the right setup can make all the difference. It's 2025, and while security technology has never been more advanced, the fundamentals of home protection haven't changed. Let me cut through the marketing noise and share what I've learned about securing your home in the Lou.

What Really Matters to St. Louis Homeowners

Value vs. Reliability: Finding the Sweet Spot

When it comes to home security, the cheapest option is rarely the best. But that doesn't mean you need to break the bank either. The sweet spot lies in finding systems that offer reliable protection at a reasonable price point.

In our testing, we found that systems in the $30-50 monthly monitoring range typically offer the best balance of features and reliability. Going below this often means sacrificing crucial features, while spending more doesn't necessarily buy you better protection—just fancier gadgets.

Quality of Life Features That Matter Most

Here's something that surprised me: the security features homeowners use most aren't always the ones that prevent break-ins. Video doorbells and garage control consistently rank as the most frequently used features across all systems we tested.

In 2025, these aren't just nice-to-haves—they're essentials. Being able to see who's at your door from anywhere or making sure you didn't leave your garage open while at work provides daily peace of mind that traditional security features don't.

Both ADT (through their Google Nest partnership) and Vivint have absolutely nailed these integrations. Their doorbell cameras offer crystal-clear video even at night, and their garage controls are seamlessly integrated into their main apps.

Beyond Burglary: Comprehensive Protection

A truly effective home security system protects against more than just intruders. Fire detection, carbon monoxide monitoring, and water leak sensors can save your property—and potentially your life.

In our testing, we found that comprehensive systems that address these multiple threats provide the greatest peace of mind. After all, you're statistically more likely to experience a house fire than a break-in.

What's State of the Art in 2025 (And What's Timeless)

Security technology has evolved dramatically in recent years. Today's systems feature AI-powered cameras that can distinguish between people, pets, and vehicles, drastically reducing false alarms. Voice control has become standard, allowing you to arm or disarm your system with a simple command.

But some aspects of security are timeless. Proper sensor placement, backup communication methods, and professional monitoring remain as crucial in 2025 as they were decades ago.

The most impressive advancement we've seen is the integration of predictive analytics. Modern systems can now learn your household's patterns and alert you to unusual activity before it becomes a problem. For example, if your back door typically stays closed between 11 PM and 6 AM, the system will notify you if it opens during those hours—even if the alarm isn't armed.

Understanding How Security Companies Operate

The ADT Ecosystem

ADT remains the largest security provider in America for good reason. Their nationwide network of six redundant monitoring centers ensures someone is always watching your home, even during natural disasters or technical outages.

What many homeowners don't realize is that when you sign up with ADT, you're often actually dealing with an authorized dealer like SafeStreets, not ADT directly. These authorized dealers must meet ADT's rigorous standards and use ADT's monitoring services, but they handle the sales, installation, and first-line customer service.

The Vivint Difference

Vivint takes a different approach with their direct sales model. When you get a Vivint system, you're dealing with Vivint employees from start to finish—no middlemen. This allows for tighter quality control but can sometimes mean less flexibility in pricing or packages.

Vivint has positioned itself as the smart home security leader, with seamless integration between security features and home automation. Their in-house developed equipment is specifically designed to work together, creating a cohesive ecosystem.

The Industry's Open Secret

Here's something most security companies won't tell you: many of them use the same underlying monitoring platforms. Alarm.com powers many local security dealers' systems, while ADT uses its proprietary monitoring network.

This means the actual "watching" of your home often happens through the same channels regardless of which local company you choose. The differences come down to equipment quality, installation expertise, and customer service.

Professional Installation vs. DIY: Why Experts Matter

After watching professionals install five different systems in our test home, I can confidently say this: professional installation is worth every penny, even for the most tech-savvy homeowners.

The Tricks of the Trade

Professional installers know exactly where to place sensors for maximum coverage with minimum false alarms. They understand the blind spots in motion detectors, the optimal height for cameras, and how to secure equipment against tampering.

For example, our DIY installation of motion sensors initially triggered false alarms whenever the heating system kicked on. The professional installer immediately identified the problem and repositioned the sensors away from air vents—something that seems obvious in hindsight but is easily overlooked.

Common DIY Mistakes

When homeowners install their own systems, they typically make several critical errors:

  1. Placing door sensors too far apart, creating gaps in detection
  2. Mounting cameras at easily accessible heights where intruders can disable them
  3. Failing to secure the system's control panel, leaving it vulnerable to tampering
  4. Overlooking critical areas like basement windows or second-floor access points

These mistakes can render even the most advanced security system ineffective when you need it most.

St. Louis Crime Trends: Why Security Matters

The statistics paint a clear picture of why St. Louis homeowners need robust security. Property crime rates are 198% higher than the national average, while violent crime is a staggering 420% above the national average. With a crime grade of 0, St. Louis ranks among the most challenging urban environments for home security.

These concerns affect everyone—both the 55.9% who own homes and the 44.1% who rent. Even if you're in a relatively safer neighborhood, comprehensive security remains essential in a city with these statistics.

The Bottom Line: National vs. Local Installers

While local security companies often advertise lower prices, our testing revealed that national providers like SafeStreets and Vivint typically deliver more consistent installation quality and better ongoing support.

The slightly higher cost of these national providers (usually $5-10 more per month) buys you peace of mind that can't be quantified—knowing that your system was installed by thoroughly trained technicians following proven protocols, and that support will be available whenever you need it.

Don't compromise on something as important as your family's safety. Choose professional installation from a reputable provider, and rest easier knowing your home is truly protected—not just giving the appearance of security.

Choosing a Home Security System Installer in St. Louis

Choosing the home security system that works best for you can seem like a daunting task but taking a few moments to assess your needs will make the decision much easier.

Rent vs. Own

Whether you rent or own will influence which home security system is right for you. Renters will want to consider systems that won’t cause any permanent damage to walls since you will likely have to either make repairs yourself or lose some of your deposit when you leave. This will also make it easier to bring your equipment with you when you decide to relocate. Another consideration for renters will be whether the landlord permits affixing security cameras to the exterior of the structure and if it can surveil common areas (e.g., apartment hallways, carports, etc.). We recommend you review your lease agreement and consult with your landlord before installing any home security system component on the exterior of a rental.

Homeowners have a little more leeway when choosing a home security system since they can attach permanent fixtures like surveillance cameras and smart locks, and they typically won’t move as often as renters. However, a greater number of potential configurations makes choosing the best home security system company even more challenging, which is why it’s important to assess your needs.

Family and Visitors in the Home

Another consideration is who lives in the residence and how many people you allow access to the home. Renters with roommates may only need a security camera for their room, whereas a homeowner may want full interior coverage. If you have kids that let themselves in after school, a doorbell camera can let you know they made it home safe. If you have caregivers or others who you allow periodic access to the home, then a smart lock with customizable codes is perfect for monitoring who is accessing the house. And of course, motion sensors and interior security cameras can let you keep an eye on those furry family members while you’re away.

Professional Installation vs. Do-It-Yourself

For smaller projects, like a single camera or smart lock installation, you may want to do it yourself if you’ve got the tools and are somewhat handy. For anything bigger or more complex, professional home security system installation is the way to go. Considering the time it’ll take you to install it yourself – not to mention the headache – any money spent on installation will be well worth it. And if you choose Vivint, installation is free.

More importantly, a professional will ensure your home doesn't have any blind-spots or weaknesses in coverage. From glass-break sensors to pet-immune motion sensors, the more layers of detection the better. If you have pets, pros like you'll find at ADT are what we recommend to most people.

How Important are Smart Home Features for protecting your St. Louis home?

It’s easy to forget that home security systems don’t begin and end with just door and window sensing. When choosing a security system for you home, some companies like Vivint have nearly endless automation options. We feel that preventing break-ins with smart home features like light automation and doorbell camera is the way to go.

Easy to Use Mobile App

Having an intuitive app that controls your home security devices from a smartphone or tablet allows you to get the most out of your investment.

How Smart Home Automation Can Prevent Crimes

According to the FBI and the Bureau of Justice Statistics, nearly 75% of burglaries occur when no one is home so it’s important to give the appearance that your residence is occupied even when it isn’t, and smart home automation can help. Automatically turning your interior and exterior lights on and off to give the appearance of being occupied is one of the key features of smart home automation, especially when you’re on vacation.

Additionally, smart door locks and automated garage door systems, like MyQ, can not only alert you when they are opened, but also answer those nagging questions while you’re away like “Did I forget to close the garage door?” or “Did the kids lock the front door when they left?”
