How does a trail camera prevent the neighbor's dog from getting caught?

It's kinda nice putting a camera over a few sets, or at least on a few entry points to see if anyone is trespassing on the line (or catch evidence if they are), but it's pretty expensive to put a camera over very many sets. I don't trap in the volumes I used to, but I'd need dozens of cameras to cover a couple hundred traps in the field. It was a full time gig keeping them tended, and going through photos of all of those sets would have taken ages! I do put "tattler" cameras on some of my lines, and I have put cameras over sets to see how they really work, but other than bait piles, I don't really make a common practice of it.
