Today’s home security systems are capable of far more than simply monitoring your home. They can integrate connected lights, locks, thermostats, smoke and carbon monoxide alarms, video doorbells, and more, and allow you to monitor and control them with an app on your smartphone. But for all their appeal, it's still difficult for consumers to compare systems because of their different components and pricing.

To help you make sense of them, Consumer Reports tested the most popular do-it-yourself systems from brands such as ADT, Brinks Home Security, Frontpoint, Honeywell Home, Ring, and SimpliSafe. Below, CR members with digital access will find ratings and reviews of the five best DIY systems from these comprehensive tests.

“Unlike many other products CR tests, DIY security systems offer many options for customization, so they needed to be evaluated from that perspective, as well as for their basic functionality," says Bernie Deitrick, CR’s test engineer for home security cameras and systems.

Deitrick grades each system for its extent of security features that CR deems essential to the job of securing your home, such as the ability to monitor a system yourself via a smartphone app, keypads and key fobs, and E911, so that you can contact your local emergency dispatcher regardless of your location. In addition to these essentials, our test engineers judge add-on security features geared toward environmental and personal safety, smart home capabilities, ease of use, ease of setup, motion detection, and security camera video quality.

5 Best DIY Home Security Systems

The top models from our tests include systems with required or optional professional monitoring. With professional monitoring, dispatchers at alarm-monitoring centers immediately notify you and the police when your alarm goes off. Self-monitored systems send an alert to your smartphone, but it's up to you to contact the police.

We note each system’s type of monitoring and the monitoring costs. Because these DIY systems are sold as kits, we also list the components included in the box.
