Yes some hotel/ apartment booking sites will have a section on what facilities they have. Like has cameras, doesn't have cameras etc.
You can always enquire , asking if they have cameras/ door camera as you like to feel safe. If they say no, and you want to book, email them and say actually although no cameras your property looks beautiful and location is ideal for my city break etc I'd still like to book.
Many door bells and cameras are wifi enabled so some girls just turn the wifi off! Personally I'd never do that as owner be suspicious!
