Child Porn or Not Just wondering?

This is a weird question. But some of us at the baseball game the other day were curious. Maybe some one can help us.

The boys are too lazy to actually walk to the bathroom. They go up in the woods and pee. I live near the field and I have a camera mounted on a tree to take pictures of the deer that come through. If one of these boys would go far enough and get their picture taken while peeing, would that be considered child porn?

The cameras are motion detected and I'm not using them to intentionally take pictures of boys peeing.

I do take the cameras down in the Summer, because the deer and turkey don't come through then. If I would happen to leave them up, could I really get in trouble if this happened?

Of course us moms thought if they get caught on camera then maybe they wouldn't be too lazy to walk to the bathroom!
