Ring Pro is very easy to install, though a little more complicated than Ring Video Doorbell 2. It's the only Ring doorbell we tested with people detection features and fully customizable motion detection zones. It also has the best video quality of the smart doorbells we tested, though it's not so much better than the competition that it's worth the higher price. This is the most expensive smart doorbell we tested, costing around $250, about $75 more than average. Unlike Ring's cheaper doorbells, the Ring Video Doorbell Pro doesn't have a battery backup, which means you need to connect it to a traditional doorbell or other compatible power source within your home. As with Ring's other doorbells, you can get excellent smart home options and cloud video storage for as low as $3 a month.
