Ring, which Amazon bought back in 2018, sells a variety of home security devices. They range from hardwired smart doorbells to battery-powered doorbells designed to replace your door's peephole. Ring also sells standalone security cameras like the Stick Up Cam Wired, lighting products and other accessories. 

Ring says its new program already works with "over 1,000" Z-Wave-enabled products today. A quick browse of the Works with Ring landing page shows integrations with Schlage locks, GE light switches and more.
