It takes one bad guest for your neighbors to be against you.
I have exterior cameras (3, recording all exterior entry points) - and noise detection devices. I quickly check the cameras at check-in and then once or twice during each day of stay. Goal is to make sure the number of people matches the reserved guest count and no parties are occurring. I don't allow guests to bring any outside visitors. I have a very strict limit on 6 people max. My house rules can't be any more clear on this - and I've still encountered a few guests that have broken the rules. They risked their stay being terminated without refund.
I charge $725/night for 6 guests - I haven't had any complaints about the cameras. 60+ reviews, 5.0 stars, been doing this for a little over a year. I am super upfront about cameras in the house rules and house manual. If I did not have the cameras, and some of the rule violations I've had, I'm not sure I'd be able to keep hosting (my county requires a special exception). It's tough out there for Airbnb hosts to be good neighbors.
Also, fun fact, Airbnb does NOT protect you from damage causes by pets.
