 You stay in a vacation rental knowing there were cameras inside? We're used to cameras capturing us outside, but one in three Airbnbs with cameras have them inside too. That can mean you're being recorded while cooking, while watching TV, or walking down the hallway. And you have to opt into this by clicking agree to complete the booking process. But even though rules are in place on indoor cameras, one in ten guests said they found hidden cameras inside of their rentals.
