You could offer to turn off your Ring, should you get one, during sits. But I’d discuss that. Some sitters appreciate security features as well.
Personally, I don’t care whether hosts might be seeing my comings and goings. If they try to micromanage me via an external camera, that would be a problem. But I also wouldn’t have an issue pushing back in a friendly way if that happened.
Separately, I did a lovely sit where the doorbell in an old home didn’t work. It was an inconvenience and I would’ve loved if they’d installed a Ring or such, because it would’ve made food deliveries much more convenient. The living room and kitchen were in a daylight basement, on a different floor from the front door, so I couldn’t hear if anyone knocked unless I was hanging nearby.
