How to Pick the Best Home Security System Installer in Longmont, CO

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

Is Your Longmont Home Really Secure? What I Learned After Testing 5 Different Security Systems

Have you ever wondered if that security system you're considering is actually going to protect your family when it matters most? Or are you just paying for a fancy doorbell and some window stickers?

Welcome to Longmont - Beautiful, Growing, and Worth Protecting

Nestled against the stunning backdrop of the Rocky Mountains, Longmont offers that perfect blend of small-town charm and modern amenities that makes Colorado living so appealing. But even in this picturesque setting, security concerns remain a reality.

After spending the last year testing five different professionally installed security systems in the same house (yes, my neighbors think I'm paranoid), I've learned a ton about what actually matters versus what's just marketing hype. It's 2025, and while security technology has never been more advanced, choosing the right installer is still crucial. Let me help you cut through the noise.

What Really Matters to Longmont Homeowners

The Value-Reliability Equation

Here's what I've discovered: the most expensive system isn't necessarily the best, but the cheapest rarely is either. What you're really looking for is that sweet spot where reliability meets value.

In my testing, systems that initially seemed like bargains often ended up costing more in frustration, false alarms, and eventual upgrades. Meanwhile, some premium features on high-end systems went completely unused.

Quality of Life Features You'll Actually Use

You know what I use literally every day? My video doorbell and garage control. These aren't just security features—they're lifestyle upgrades.

When my grocery delivery arrives, I can verify it's at my door from anywhere. When I can't remember if I closed the garage after leaving for work, I don't have to turn around—I just check my app. Both ADT (with their Google Nest integration) and Vivint have absolutely nailed these features in their 2025 offerings.

Peace of Mind: The Real Investment

Let's be honest—the statistical likelihood of experiencing a break-in is relatively low for most homeowners. But security systems provide something more valuable than just burglary prevention: peace of mind.

And don't forget fire safety! Modern systems now integrate smoke and carbon monoxide detection with professional monitoring, potentially saving lives when you're not home or asleep.

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

Security technology has evolved dramatically, with AI-powered cameras that can distinguish between a package thief and your neighbor's cat, and sensors that are virtually tamper-proof.

But some aspects remain timeless: strategic sensor placement, backup power systems, and reliable monitoring services will never go out of style.

The integration of voice assistants has become seamless in 2025, with systems responding to nuanced commands like "I'm going to bed" (which can arm the system, lock doors, adjust thermostats, and turn off lights).

Battery life has also improved dramatically—most wireless sensors now last 5+ years before needing replacement, a vast improvement from the 1-2 year lifespan common just a few years ago.

Understanding How Security Companies Operate

ADT: The Industry Standard

ADT operates their own UL-listed monitoring centers across the country, providing redundancy if one center goes offline. Their model involves professional installation, equipment leasing or purchasing, and monthly monitoring fees.

SafeStreets: An ADT Authorized Dealer

SafeStreets is an authorized dealer for ADT. This means they sell, install, and service ADT equipment, but your monitoring contract is ultimately with ADT. SafeStreets handles the sales and installation, then transfers your account to ADT for monitoring.

This arrangement gives you local installation expertise with the backing of ADT's national monitoring infrastructure.

Vivint: The Direct Sales Approach

Vivint takes a different approach, handling everything in-house from sales to installation to monitoring. Their focus on smart home integration is evident in their sleek, unified ecosystem where security and home automation blend seamlessly.

Local Dealers and Monitoring Services

Many local security companies in Longmont actually operate as authorized dealers for larger brands like ADT. Others use third-party monitoring services like Alarm.com, which powers many local and regional security providers nationwide.

This isn't necessarily bad—it often means you get the same reliable monitoring as national brands, sometimes at better prices. But it's important to understand who's actually monitoring your system.

Professional Installation vs. DIY

After watching professional installers work and then attempting some DIY installations myself, I can confidently say: there's a significant difference.

The Professional Advantage

Professional installers know the "tricks of the trade"—like placing motion sensors at specific angles to maximize coverage while minimizing false alarms from pets or HVAC systems. They understand the blind spots that burglars exploit and how to counter them.

They also know how to properly secure sensors against tampering, something many DIYers overlook entirely.

Common DIY Mistakes

The most common mistakes I've seen (and made myself) include:

  • Placing door/window sensors too far apart, creating unreliable connections
  • Installing motion sensors where sunlight or heating vents trigger false alarms
  • Failing to account for pets' jumping abilities when positioning sensors
  • Not securing the control panel against tampering
  • Poor camera placement that captures too much irrelevant motion

When it comes to your family's safety, this isn't the place to cut corners or learn by trial and error.

Longmont Crime Trends: Why Security Matters

The statistics don't lie: property crime in Longmont is currently 41% higher than the national average, while violent crime is 3% above the national average. With a crime grade of 1, security concerns are valid for both the 35.9% who own homes and the 64.1% who rent.

While these statistics shouldn't cause panic, they do underscore the importance of taking reasonable precautions to protect your property and loved ones.

The Bottom Line: National vs. Local Installers

After my year of testing, here's my honest assessment: while local companies often offer competitive pricing and personalized service, the consistency, technology integration, and reliability offered by established national installers like SafeStreets and Vivint typically justify their slightly higher costs.

The peace of mind that comes from knowing your system is backed by companies with decades of experience and 24/7 monitoring centers can't be overstated.

Whatever you choose, please prioritize professional installation. The difference between a properly installed system and an amateur setup could be the difference between security and vulnerability when it matters most.

Your home is worth protecting the right way. After all, true security isn't just about having equipment—it's about having the right equipment, properly installed, professionally monitored, and ready when you need it.

Choosing a Home Security System Installer in Longmont

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 Longmont 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?”
