Like a Vivint system, the SimpliSafe home security system comes with its own unique equipment. SimpliSafe is the OG DIY system, so everything is super easy to set up yourself. You'll find indoor and outdoor cams and a video doorbell. While SimpliSafe isn’t great at home automation and smart home stuff, its cameras are effective and affordable, and it has a few special pieces, like its very own in-house smart lock. And if you're a fan of August smart locks, SimpliSafe systems are perfectly compatible. You'll be able to control your August smart lock from a SimpliSafe home security system keypad, mobile app, or key fob.
