We’ve tested the SimpliSafe system several times and most recently gave it a review score of 8.5 out of 10. If you’re looking for home security — without all the extra Wi-Fi and smart home integrations of the Ring Alarm Pro — SimpliSafe’s easy-to-install, easy-to-use DIY system is a great option. It offers a comprehensive set of features, including equipment like security cameras and a very good mix of battery-powered motion detection sensors, all of which performed reliably well in our tests. Starter kits begin at less than $250, or you can build a custom alarm system with the exact mix of devices you need. The security company’s professional monitoring plan starts at $18 a month, but you’ll almost certainly want to spring for the $28-a-month monitoring service plan, which adds in things like mobile app controls and smart home security system voice support via Alexa and Google Assistant.
