The ring camera is an elegant looking relatively inexpensive camera with a very good picture and an easy to use app for monitoring. Video can be stored to the cloud for a price and it can link up with other cameras and can display on any Alexa video device.  It is quite small- smaller than your hand- but has clear images both day and night.  If you mount it to a wall instead of using the stand you will need longer screws than they give you  and it's usb cable is way too short to mount far from power and seems to be proprietary so you may not be able to get a longer one if needed.  But for the price an attractive and very workable device.
