@Mike1667 I'm not clear on what exactly you'd want monetary recourse for, but I don't see anything here that applies.
Your Ring doorbell footage should indicate how many people entered the property, so if they exceeded your capacity your choices would have been to either amend the booking to reflect the total or ask the unregistered guests to leave. Without a listed Extra Guest Fee, you'd have no grounds to ask for extra money.
Same goes for smoking - you can ask the guests to stop smoking, or you can kick them out for breaking your rules, but you don't really have grounds for a damage claim if there wasn't damage.
Airbnb does have some provisions for Overstay Fees (see Sec. 8.2.2. of the Terms of Service) but it's hard to imagine that 45 minutes would be worth pursuing.
Bottom line is, the job of enforcing your rules and keeping control over your property falls onto you as the host, and you have to do it in real time. If you expect your primary recourse to run through Airbnb, you'll be very disappointed with the results.
