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.
The professional cameras are hardwired, so a wifi jammer (illegal) wouldn't work.

What brands are the pro ones?
