That line about wondering what they saw on their end got me. It reminds me of when my old baby monitor would sometimes pick up a signal from another house. I'd hear a totally different kid crying or people talking. It was creepy but also just cheap tech. Your story is way worse because it's video and it's supposed to be secure. Makes me not trust any of these cloud connected gadgets.

Maybe everyone's just looking for a new hobby post-pandemic.

Seriously, that ending of 'The OA' was perfect as it was.
