Just a quickie summary here...
Keeping and installing the Ring Doorbells. Returning the smart IP camera because it is slow to update and slow to appear on the Amazon Alexa Show.
The neighbor wants a bit more security than what the Ring offers so have suggested getting the Ring security stuff / plan for security.
The 5 device package was on sale for $100 and see them on Ebay for less than $150. Will probably set this up for them in the near future.
No contracts and a reasonably priced monthly charge (with no automation). ~ $14 / month for just security or ~ $24 / month with automation.
Personally here prefer my wired security primarily and do use wireless HAI OmniPro last choice trinkets (have both HAI wireless receivers here).
