Up until Monday I was the same mind as you about my camera’s Tin - wont prevent anything, but there just to find out what went wrong, unless it was a full break in. Monday just showed me you just never know.I've been of the opinion that cameras don't really prevent anything but just tell you what/who happened. This sure proves that theory wrong!
It also shows that God works in mysterious ways! He gave you a VRBO neighbor that caused you so much concern you got smart-home security cameras which saved your cabin. I think He really wants you to keep that cabin!
