I'm replacing my Ring doorbells today. I have two, one for the front door and one for the outer courtyard door, and they pick up everything from cars driving by and the postman dropping off mail to a little bat who hunts mosquitos in my courtyard.
What they do not pick up are Amazon deliveries. Neither the truck nor the delivery guy trigger the motion sensor or video recording on either Ring camera.
They either turn the Rings off as the Amazon truck pulls up or they use a jammer. Creepy.
This has been reported, in various forms, on the Ring forums, Reddit, etc. for years - for Amazon, FedEx, USPS, UPS, etc.
It feels less related to anything malicious as the general unreliability of un-wired signals and the fact all the package services carry scanning devices.
I have a Gen1 Ring and it's a great video doorbell. As a security or package cam? Eh, hit or miss.
Now, about privacy and security - EFF has a LOT to say about Ring - https://www.eff.org/search/site/ring
Anyone looking for a security device is probably better off going with a more expensive closed circuit system.
I love my Ring, but I have it purely because we never use the front door, hardwiring is not an option (old house) and I like to screen the cookie sellers (bring 'em on) from the Witnesses.
Oh and I like to laugh at the folks on Neighbors convinced everything is gunfire. 🤣
