The cool thing is, if you're the right Amazon employee, you can log in and literally _see_ the anger on their faces next time they go in the front door.[1]
Yes you could install a credit card reader on the doorbell and shame the owners by alerting their visitors to the fact that they've not paid the bill, but informing them that they can ring the bell for a minimal yearly subscription.
Company has recurring expenses to keep your cloud-connected device running. They need recurring revenue to cover those costs. Depending on one-time revenue from the sale of new devices to cover the recurring expenses of existing devices is a pyramid scheme, no?
I have an IoT graveyard of devices from companies that did not charge a monthly fee and went under (Edyn garden sensor, Automatic car monitor, etc).
We have Nest cameras, and the basic 30 day recording service is $80/year (though we have 2 doorbell cameras and 6 other cameras around the property) so for us its a good value, and $60/device under ring would be crazy. But if you have just the doorbell , then the Ring was and is the better value over Nest.
I’m not familiar with Ring, but if it’s anything like their Blink cameras I wouldn’t count on it. The Blink cameras advertise a local only mode, but the functionality is reduced to make it unusable. You lose thumbnails for videos and they take away the ability to bulk delete (IIRC). Have fun navigating into every video, waiting for it to start playing, and then deleting it.
The other catch is if “the cloud” is needed to generate thumbnails, it’s not a local only mode.
