Game cams are great devices! I don't have one, but I have a pretty good hunch that there are many wood-be predators deterred from snacking on my chickens by my hot wire system as I've actually watched (during the day) as bears come up to the hot wire around my coops and runs and sample the peanut butter bait on the wire. I never knew bears, as they sample the peanut butter, could execute perfect ballet pirouettes as they do a 180 and run off never to return.
Your system has a better chance of discouraging expert climbers such as bob cats if you also run a hot wire within a few inches of the top of your fence. Climbers often will smell or lick the top of the fence as they are scaling it.
I use short pieces of PVC pipe stuck onto the tops of my steel T-posts, holes drilled through the tops and wire threaded through them. PVC makes excellent and very cheap insulators.
