The actual range varies—this combo has gone for as little as $199 at times in the past, and as high as $299. At this very moment, Amazon has the non-discounted priced marked at $273.99. The $169 price is good for Prime members only.
To our knowledge, this is the lowest price this combo has ever been on Amazon. As its name implies, the Ring Video Doorbell Pro is a smart doorbell, with Full HD 1080p video support for live, on-demand feeds. You can get alerts on your phone, tablet, and PC when anyone presses the doorbell or triggers the motion sensors.
The smart doorbell also features two-way talking, like a modern day intercom (that works with your phone or smartphone speaker). It works with Alexa as well, to send announcements to Echo devices, such as the included Echo Dot.
