I would be so mad. I would etup a trail cam in a spot where there is decent cover behind it and mount another one overlooking that camera. Or if there is a specific way people drive/walk in put a camera up there. I caught people (trespassing) hunting on my lease, and I put up a camera in some thick brush by the driveway and caught their liscense plate and what they look like. Make sure it doesn't have any flashing red lights when it takes a picture like some do. I even got pics of them sneaking in right before light with a shotgun. If you haven't already put up some purple paint, or a no trespassing sign. I would definitely talk to the landowner in this case. hope this helps, good luck!
