WHAT SimpliSafe

THE COST Starter kits begin at $280; plans start at $10 per month

AVAILABLE FROM simplisafe.com

 If you're looking for home security — without all the extra Wi-Fi and smart home integrations of other systems — 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 good mix of battery-powered motion-detection sensors, all of which performed reliably well. You can opt for a starter kit or you can build a custom alarm system with the exact mix of devices you need. If you opt for the $30-a-month professional monitoring service plan, it includes 24/7 live guard protection, whole home monitoring, instant app alerts and faster response times.

WHAT Vivint Smart Home

THE COST Plans start at $10 per month

AVAILABLE FROM vivint.com

Vivint gives you a super-polished experience with third-party device integrations — and it doesn't require a contract. The starter package includes only a touch screen and a couple of sensors, but Vivint works well with voice assistants like Google Assistant and Alexa and supports a wide array of additional Vivint and third-party devices. You can also adjust your budget based on what you'd like to buy now and purchase later.

WHAT Ring Alarm 8-Piece Kit (second-generation)

THE COST $249.99

AVAILABLE FROM ring.com

This eight-piece starter kit provides four important sensors, a base station plus a keypad, a motion detector and a range extender for those worried about Wi-Fi. The Pro version of this package is also good, but the second-generation kit is a bit newer and doesn’t force you to use the built-in router. Amazon’s Ring devices include excellent Alexa support, and DIYers will like the largely intuitive management app. In addition to direct controls and sensor notifications, users can also switch between home and away modes on the fly. If you decide to expand, almost any Ring product will be compatible including their security cameras and video doorbells, so it’s easy to level up.
