How Much Does a Home Security System Usually Cost?
“What’s the price tag?” It’s one of the first questions homeowners ask — and one of the hardest to answer. Security systems can range from a few hundred dollars to several thousand, depending on what they include and how they’re monitored.
The challenge is that “home security” can mean a lot of different things: a few sensors and a phone app, a fully monitored system, or a setup that includes cameras, smart locks, lighting, and more.
This guide breaks down what actually affects the cost — so you can understand what you’re paying for, what’s worth it, and what level of protection makes sense for your home.
What People Typically Spend
Most professionally installed systems fall into a few ranges:
- $500–$1,500 → basic sensor-based setups
- $1,500–$3,500 → added cameras, control, and broader coverage
- $3,500+ → full systems with integration, automation, and larger properties
Plus optional monitoring, which is usually $20–$60/month, depending on features and response level.
That still leaves a pretty big range. So what actually drives those price differences?
What Goes Into the Cost of a Security System
At its core, a security system is built from a few key layers:
Detection
Door, window, motion, and glass-break sensors that alert you when something happens.
Visibility
Cameras and doorbells that let you see activity in real time — and review it later.
Response
Notifications, alarms, or professional monitoring that determine what happens next.
The more layers of protection you add — and the more advanced they become — the more your system will cost.
The Difference Between Self-Monitored and Professionally Monitored Security
When an alarm is triggered, the system itself is only part of the equation.
What matters just as much is who gets the alert — and what happens next.
Self-Monitored
Alerts go directly to you, and you decide how to respond.
- No (or lower) monthly fee
- Alerts go to your phone
- You decide how to respond
- Relies on you being available
Professionally Monitored
Alerts go to a 24/7 monitoring center that can respond and dispatch help if needed.
- Monthly monitoring cost
- Alerts go to a monitoring center
- Can dispatch emergency services
- 24/7 response, even when you’re busy
Professional monitoring is one of the biggest differences between a basic system and a more complete one — and one of the biggest drivers of monthly cost.
How Security Features Affect Cost
Beyond the type of monitoring, the biggest factor is simply how much you want your system to do.
-
Sensors
Door, window, motion, and glass-break sensors are the foundation of most systems. More entry points = more sensors. -
Cameras & Video Doorbells
Adding cameras increases cost, but also gives you live video, recorded footage, and the ability to see what actually triggered an alert. Camera cost can also vary based on resolution, night vision, two-way audio, and whether footage is stored locally or in the cloud. -
Smart Locks
Remote locking, custom user codes, and activity notifications add both convenience and security. -
Security Lighting
Smart lighting can illuminate vulnerable areas, turn on automatically, and even work with your cameras. -
Presence Simulation
Some systems can make it appear like someone is home by automatically turning lights or TVs on and off. -
Video Analytics
More advanced systems can tell the difference between a person, a car, or an animal — reducing false alerts and making the system smarter.
Each feature adds functionality and helps the system do more than just trigger an alert. For some homes, a basic system is enough. But for others — especially larger homes, families, frequent travelers, or anyone wanting more peace of mind — a more complete system often makes sense.
So… What Should You Actually Expect to Pay?
If you only want a few alerts on your phone, you may only need a few hundred dollars’ worth of equipment.
If you want broader coverage, cameras, remote access, and professional monitoring, expect to spend more — both upfront and monthly.
The “right” amount of security isn’t really about price.
It’s about choosing a system that matches your home, your habits, and the level of protection you actually want.
How Sundance Approaches Home Security
Sundance doesn’t believe in one-size-fits-all packages.
Instead, we help homeowners build a security system around the way they actually live — whether that means simple home surveillance, professionally monitored protection, smart locks and doorbells, or a fully integrated setup.
Because the best security system is not about being the cheapest or most expensive.
It’s the one that gives you confidence every time you leave home (or turn out the lights at night).

Ask a Technician FAQs
Do I need professional monitoring?
Not always. But if you travel often, have children, or want emergency response even when you’re unavailable, it’s worth considering.
What’s the most important part of a security system?
For most homes, the foundation is sensors and monitoring. Cameras and smart features build on those choices.
What extra features are “worth it”?
Cameras, doorbells, and smart locks are some of the most commonly added — they add both security and convenience.
What adds the most to the cost?
Advanced cameras, professional monitoring, and integrated smart features tend to have the biggest impact on cost.
