This page documents exactly how we evaluate and score home security systems. We publish our methodology because transparency is the foundation of credible editorial content — you should be able to verify our work.
Key takeaways
| Dimension | Weight | What we measure |
|---|---|---|
| Monitoring quality | 30% | Response time, Five Diamond certification, redundancy, cellular failover, dispatch accuracy, 24/7 availability |
| Equipment value | 20% | Hardware cost vs. coverage area, sensor quality, camera resolution, battery life, warranty, financing terms |
| Ease of setup | 20% | Installation time (DIY or professional), app quality, configuration complexity, customer support |
| Contract terms | 15% | Cancellation policy, penalty fees, minimum term, equipment financing separation, price lock |
| Smart home integration | 15% | Amazon Alexa, Google Home, Apple HomeKit, Z-Wave, Zigbee, third-party automation |
Each dimension is scored 1–10 using a sub-criterion rubric. The final score is the weighted average, rounded to one decimal point.
We include a home security system in our scored reviews if it meets all of the following criteria:
| Source type | What we use it for |
|---|---|
| Brand pricing pages | Equipment costs, monitoring plan pricing, contract terms — verified before each publish |
| FCC filings | Sensor radio frequency, range specifications, regulatory compliance |
| UL certification database | Monitoring center Five Diamond status, equipment certification |
| BBB complaint data | Customer service quality signal, complaint resolution rate |
| Consumer regulatory filings | State licensing, false alarm data where public |
| Hands-on testing (where conducted) | Direct evaluation of install process, app, and sensor behavior — clearly noted in each review |
Note on hands-on testing: Where full hands-on testing has been conducted, it is explicitly noted in the review. Where desk research was the primary method, this is also noted. We do not claim hands-on experience we haven't had. Learn more about our testing process →
