Originally I put the cameras up because of losses due to predators. I have electric wire around my coops and pens because of a bobcat and a possum digging under the fence, concrete under my gates because of a fox and a skunk digging under some gates and heavy duty netting covering all of the pens because of an owl and a coyote that jumped over a 5' fence into a pen and killed some birds. The owl was a hard one to figure out until I put up a game camera and caught it in action. Not long ago I lost 3 birds. One was very special and a fox took her in the middle of the day.
