If you’re searching “how much does a home security system cost,” you’re probably past the question of whether you need one. You already know you do. Now you want real numbers before you pick up the phone.
We get it. Nobody wants to call a security company and feel like they’re walking into a car dealership. So here’s the honest breakdown of security system cost in 2026, from equipment to monthly monitoring, with real price ranges and no fine print.
The Short Answer: What Does a Home Security System Really Cost?
Most homeowners spend between $200 and $1,500 on equipment, plus $20 to $60 per month for professional monitoring. That’s a wide range, and your actual cost depends on the size of your home, how many doors and windows you want covered, and whether you want extras like cameras and smart locks.
The good news? A solid, professionally monitored system doesn’t have to break the bank. Our monitoring plans at Dehart start at just $22/month, and we’ll walk you through exactly what you need without pushing products you don’t.
Equipment Costs: What You’re Paying For
The equipment is your upfront investment. Think of it as the hardware that actually protects your home. Here’s what the major components typically cost in 2026:
| Equipment | Typical Cost Range | What It Does |
|---|---|---|
| Security Panel / Hub | $100 – $400 | The brain of your system. Controls everything and communicates with the monitoring center. |
| Door/Window Sensors | $15 – $40 each | Detects when a door or window opens. Most homes need 6 to 12. |
| Motion Detectors | $20 – $50 each | Picks up movement inside your home. Pet-friendly options available. |
| Security Cameras | $100 – $300 each | Indoor or outdoor video monitoring with live streaming and recording. |
| Doorbell Camera | $100 – $250 | See and talk to whoever’s at your door from your phone. |
| Smart Lock | $150 – $300 | Lock and unlock your doors remotely. Create guest codes. Get alerts. |
| Glass Break Detector | $30 – $60 each | Listens for the sound of breaking glass and triggers the alarm. |
| Smoke/CO Detector | $40 – $80 each | Monitored fire and carbon monoxide detection. Dispatches fire department automatically. |
| Water Leak Sensor | $30 – $50 each | Alerts you to leaks before they cause expensive water damage. |
| Smart Thermostat | $100 – $250 | Control your AC from anywhere. Helpful in Florida where cooling bills add up fast. |
A basic setup with a panel, a handful of sensors, and a motion detector might run $300 to $500. A more complete system with cameras, smart locks, and environmental sensors could land between $800 and $1,500. Every home is different, which is why we always recommend starting with a free consultation rather than guessing.
Monthly Monitoring Fees
Equipment protects your home. Monitoring protects your family. Here’s the difference: if your alarm goes off and nobody’s monitoring it, it’s just a loud noise. With professional monitoring, a real person at a real monitoring center verifies the alert and dispatches police, fire, or EMS within seconds.
Monthly monitoring fees across the industry typically fall between $20 and $60 per month. What you pay depends on what’s included:
- Basic monitoring ($20 – $30/month): 24/7 alarm monitoring, police and fire dispatch, and basic app access
- Mid-tier monitoring ($30 – $45/month): Everything above plus video monitoring, smart home controls, and cloud storage for camera footage
- Premium monitoring ($45 – $60/month): Full smart home integration, advanced video analytics, energy management, and priority response
At Dehart, our monitoring starts at $22/month. That includes 24/7 professional monitoring from our own UL Listed monitoring facility right here in Florida. We don’t outsource your safety to a call center across the country. When your alarm goes off at 2 a.m., it’s our team that responds.
Professional Installation vs DIY
You’ll see a lot of home security system cost comparisons that push DIY as the affordable option. And sure, buying a box of sensors off the internet and sticking them on your doors yourself will save money upfront. But there are tradeoffs worth knowing about.
DIY systems typically cost less in equipment ($150 to $400) because you’re doing the labor. But sensor placement matters. A motion detector in the wrong spot creates blind spots. Cameras angled poorly miss the areas that matter most. And if something isn’t wired or paired correctly, you might not find out until the system fails to trigger when you need it.
Professional installation usually adds $100 to $300 to your total cost, but you get a trained technician who knows exactly where to place every sensor for maximum coverage. They’ll test every component before they leave and walk you through how everything works.
We’ve been installing home security systems across Florida since 1967. Our technicians have seen every type of home layout, from compact condos in St. Pete to sprawling properties in Sarasota. That experience means your system is set up right the first time.
What Affects Your Total Cost
No two homes are the same, so no two alarm system cost quotes will be identical. Here are the biggest factors that move the number up or down:
- Home size: More square footage means more sensors and potentially more cameras. A 1,200-square-foot condo needs far less than a 4,000-square-foot house.
- Number of entry points: Every exterior door and accessible window is a potential point of entry. More entry points mean more sensors.
- Camera count: Cameras are the biggest variable in most quotes. One doorbell camera keeps costs low. A full four-camera setup with cloud recording adds up.
- Smart home features: Want smart locks, a connected thermostat, and automated lighting? These add value and convenience but also add to the equipment cost.
- Wired vs wireless: Wireless systems are easier to install and usually cost less for installation. Wired systems are more reliable for larger properties but take more labor to set up.
- Monitoring level: Basic monitoring is affordable. Adding video verification, cloud storage, and smart home controls increases the monthly fee.
- Contract terms: Some companies lock you into 3- to 5-year contracts with steep cancellation fees. Always read the fine print. At Dehart, we don’t believe in trapping customers. We keep them by doing a good job.
Why the Cheapest System Isn’t Always the Best Deal
It’s tempting to go with the lowest home alarm system cost you can find. But the security industry has a pattern you should know about: some companies advertise “free” or ultra-cheap equipment, then bury the real cost in long contracts, hidden fees, and price increases after the first year.
Here’s what to watch out for:
- Long-term contracts with auto-renewal: That $15/month plan might require a 60-month commitment. Do the math. That’s $900 you can’t walk away from, even if the service is terrible.
- Equipment rental fees: If you don’t own your equipment, you’re paying for it forever. And if you cancel, they take it back.
- Rate increases: Some contracts allow the company to raise your rate annually. Your $20/month plan could be $40/month by year three.
- Outsourced monitoring: Budget companies often outsource monitoring to third-party call centers. Response times can suffer. The person on the other end might not know your area or your system.
We wrote a deeper guide on how to evaluate security companies that applies to residential customers too. The same principles hold: know what you’re signing, understand who’s monitoring your system, and ask about every fee before you commit.
