The game camera is a good idea. Why don't you also enlist and pay the tenants kids in "helping" you fix the broken shutter and locks and then also in helping you to keep your barn secure (keep an eye out, call you etc.) Of course asking the parents for their approval first would be a good idea.
We used to have some rowdy teens in our neighborhood, racing up and down the street, playing loud music, etc. All the neighbors gave them a hard time. We needed to have a fence in the common area repainted so we approached the teens to see if they wanted to earn some extra money. Guess what - they did a great job painting the fence and the rowdy behavior subsuided also.
Ownership is a good gift to give.
