Use a surgical mask instead of a banana. It feels less aggressive.

You have valid concerns. It’s an unfortunate shifting landscape. There’s no opt-out for collection devices you don’t own (it’s hard enough already for the ones you do own) so consent has disintegrated completely. The reflexive reaction is threat model focus and adjusting your expectations of privacy. But what’s becoming more complex at that approach is how widely and with whom the data is being shared. If the doorbell server owner was using it to improve the doorbell product only, it wouldn’t be so concerning. But when it becomes a data harvesting tool for law enforcement or any other company willing to pay, relatively trivial data collection becomes much more imposing since it can be combined with other sources.

I am not at shirt-over-my-face level yet, but I would feel much more comfortable with a face mask any time I approach an unknown camera, which is increasingly common these days.

I don’t turn my face towards houses while I’m walking if I notice a doorbell camera

I do that haha… In all seriousness, I’ve recently quit my job as mailman, in part because of this. Year after year I saw the number of doorbell cameras increase, and so grew my discomfort of my job requiring me to expose myself, to these privacy-hostile situations. The worst case scenarios were semi-detached houses: since the doors to the paired addresses are right beside another. Between the entries there’s often (decorative) separation, requiring some acrobatics to shortcut to the next address. If the second address would have a doorbell camera, while requiring me to sidestep between the obstructions, I could either: A) face the door and have my face right up to the camera, or B) turn my back to it and spin back into position. I did the latter, and I HATED having to adapt my seemingly simple job to this extend, just to protect my dignity.

The Netherlands technically requires a sign which indicates camera surveillance, besides having to direct cameras in such a way that they cannot capture the public sphere. But have a guess at how much enforcement there is in this regard…

When you walk and attempt to protect your privacy, are you wearing or carrying any WiFi and/or Bluetooth devices? Ring devices are Amazon Sidewalk devices. They’ll record nearby devices like your phone, whether you want it to or not.
