How Much Does a Home Security System Cost?

Thinking about adding a home security system? It’s a smart decision—and not just for peace of mind. Studies show that homes without security systems are significantly more likely to experience break-ins, with some estimates suggesting they're up to 300% more likely to be targeted.
But one question always comes up early in the process: How much does a security system cost?
The short answer: it depends. The total cost of a home security system is shaped by a range of factors including the type of equipment you choose, the level of protection you need, the size of your home, and whether you opt for smart features or professional monitoring. Here's a breakdown to help you plan.
What Impacts Home Security System Pricing?
Several elements influence how much your home security system will cost:
Number and type of devices: entry sensors, indoor/outdoor cameras, smoke, and/or CO detectors.
Monitoring choice: self-monitored vs. professional monitored.
Installation: DIY vs. professionally installed.
Smart home feature: locks, thermostats, and lighting.
Home size and layout: larger spaces typically need more coverage.
Understanding these elements can help you navigate pricing with more clarity, as well as find a solution tailored to your home’s unique needs like layout and priorities.
Professional Monitoring vs. Self-Monitoring
Professional monitoring plays a big role in answering the question, how much does a security system cost?
For a monthly fee, monitoring services keep an eye on your home around the clock. If a break-in, fire, or other emergency is detected, the monitoring center contacts emergency responders immediately.
In addition to peace of mind, this added protection can offer:
Faster emergency response times.
24/7 alerts—even if you're out of town or away from your phone.
Homeowners insurance discounts from some providers.
Some homeowners opt to self-monitor their system, but professional monitoring ensures nothing slips through the cracks.
Do Smart Home Features Increase Cost?
Smart home technology has become more accessible and more popular. With it comes convenience—but also additional cost depending on your setup.
Smart security features may include:
Video doorbells with two-way talk and real-time alerts.
Smart thermostats that adjust automatically or remotely.
Door locks you can control from your phone.
Smart plug automations for added safety when you’re away.
Tip: Start with core security, then layer in smart tech over time as your budget allows.
Is Professional Installation Worth It?
While some systems are designed for self-installation, professional installation provides added assurance that your equipment is properly placed and fully functional.
Professionally installers ensure:
Equipment is placed for maximum coverage.
You avoid dead zones or false alarms.
Systems are synced with your mobile app correctly.
Look for professionally installed systems that include free installation with new system activation (like Brinks Home™), which eliminates one of the most common up-front costs. This can be especially helpful if you’re new to smart home devices or have a more complex layout to secure.
Other Factors That Affect Total Home Security Cost
Beyond equipment and monitoring, a few other considerations can influence your total cost:
Service agreements: Some providers offer locked-in rates, which prevent price hikes over time.
Equipment warranties: Coverage for hardware repair or replacement may be included.
Support and app access: Some systems charge extra for mobile app use or tech support—others include these as standard.
Expandable systems: The ability to add devices over time can help manage costs gradually.
Asking the right questions upfront can prevent unexpected fees or functionality limitations later.
