I don’t see the necessity of discussing why any serious host would require a camera inside their rented accommodation.
BUT - as I just updated our information regarding the surveillance cameras on our property, following Airbnb’s requirements (add details in the safety section) - I was more prominently made aware that now every website visitor on Airbnb can easily find out about the location of our security cameras without even having to register an account on Airbnb. Thank you Aribnb!
