A couple weeks back we were on vacation in Hawaii, and one night at dinner the table of San Diegans next to us was having a rather loud and animated conversation. It seems they had rented out their property back home on Airbnb and they very clearly talked about not disclosing the cameras they had onsite to the tenants.
The tenants had discovered at least the doorbell camera and covered it up, to which the owners were not pleased and were debating calling the police on the tenant.
We were aghast at their complete lack of knowledge regarding undisclosed video surveillance of tenants and the violation of airbnb policy. My wife badly wanted to interject but we let it go. We did talk about how to mitigate these threats, made for some interesting vacation dinner conversation though.
