Achieving peace of mind for your home doesn’t have to be pricey or difficult.Traditional home security systems often require long contracts and expensive professional installation, but most smart DIY security systems are affordable and easy to install, and they allow you to pay for a monitoring plan only when you want it.Ring offers two of the best-performing and easy-to-use DIY home security systems we’ve tested: the Ring Alarm Pro and the standard Ring Alarm. You can set up and control either system using the same simple smartphone app, customize yours to suit your preferences with a wide range of add-on accessories, and the monitoring plan is the most comprehensive yet still one of the least expensive. Ring is also the best home security system if you plan to use cameras, since they offer more options than any of our other picks and include video storage as part of the monitoring plan.
