I only just got (and failed to do adequate buyer research) but have not installed a Eufy doorbell and learned of the unencrypted upload of clips. I got it because I wanted interior (rather than onboard Sd card) local storage, but if a thief can wipe my data using the doorbell itself, the data is not secure. (see my other thread inquiring about any solution - like password protecting erasure, or a physical lock).
Anyway for people with a good router, or one that will allow custom firmware, routers can be made to block outgoing internet traffic from a device. So if you do not want/need a subscription service and only want to use local storage, you can block your doorbell from uploading tro the internet. Problem solved. You do not need Eufy to do anything in order to fix this.
This is not a major concern as my doorbell faces a public street so any clips would be what someone could come by to see . I suppose there is some slight risk that the clips could be used to develop facial recognition of me and my family or to rack comings and goings, but these are a low risk for me.
Caveat, I have not tried this as I have not yet installed my eufy do to my other concern. I may be returning it.
