I would worry about something "happening" to the camera if they were installed indoors. 

Is your property set up as just a place to sleep, maybe a place to relax and stay indoors, maybe long term guests or an older crowd... then think about what they may want.

Since I have to choose, I'll go with the one that has no shower and no indoor plumbing but a billion dollar sky. https://www.airbnb.com/rooms/3...

Unless you’re dealing with c-d neighborhoods, always include a nice stainless ice/water in door fridge.

@Matt LindseyFind a hygenist to run a test - a real mold test will test the outdoor and indoor air as that is the only true way to test since mold is everywhere - the test is to check if the mold spores indoors are different than those outdoorsNote it is also spring which news alert - people get allergies

.#1 - I have indoor pools in some of my cabins and the insurance company provides me with specific verbage they want in my rental agreement and they want that initialed by the guest.#2 - I "feel" like I would have better coverage if something bad happened and I was taken to court from a liability standpoint.  

We rent a nice pool home with indoor and outdoor seating areas so everyone is comfortable.

Did you check the lease they are currently on to see if smoking indoors was prohibited?

i got in a company called BLINK as a start up. they are owned by Amazon now. i love my systems they work off of WiFi. the cameras are completely wireless the single AA battery lasts about a year and they have indoor and outdoor versions.  

You can create a rule that says if the indoor temperature reaches “x” degrees, then turn the heat on, AC off, etc.
