Hi @Tina457, you have a lovely home. I'm sure you'll have many more happy guests that do jot abuse your hospitality.
I had a look at your listing. To avoid accusations of surveillance and espionage, just be clear in your listing that you have a Ring doorbell video, and any other cameras that may exist. Add this in the write up about the space, and repeat it under 'Other Things to Note'. Of course, most guests won't read it, but it definitely helps when you take your case to Airbnb if you need to go to mediation. I'd word it as something like 'for guest safety, and to prevent/deter crime, we have a Ring doorbell video system fitted, which covers xx part of building and garden, and the front door'
And I agree with @TracieandJason0, make it seem like you're around the property more, for instance to tend the garden or something where you can be seen, but are not intrusive.
