This is the Apple of home security systems. It's easy to set up and has outstanding customer support, with detailed instructions for resolving any problems you might encounter. The app that controls the sensors, Hub and siren is simple and self-explanatory, so you don’t have to be a tech expert to use it. And if you forget to arm the system when you leave the house, the app will alert you—as my kids always forget to do this with our old security system! Highly recommended
