Trail Cam for Trespassers?

[Tom McQuinn]

I confess that this is for my residence but I am an investor and I do hope to sell it for a profit someday.

Back in 1992 I lost my mind and bought a 1.15 acre wooded lot in one of the better areas of town.  I totally underestimated how much work, expense, and hassle it would be.  Using fencing, I've basically divided it into 2 lots so I can keep my dogs within sight.  I won't even try to describe the history of problems I've had with the back lot.  It's actually easier to take care of now that all the Ash trees have died.  But today I found 2 crack pipes in the back lot.  This is not going to continue.  I don't want to start a fight here but the cops here are useless for this sort of thing.  Has anyone ever used a trail cam and gotten good enough photos of trespassers to be of use to the police?  I'd like to try something that doesn't involve me going back there with a shotgun in the middle of the night.
