Depending on your use not all game cameras are the same. All pretty much take good daytime picture but not all are equal for nighttime pictures. Here most of the predators roam at night. I think the adults teach their young that a bird isn't worth getting a good zap for. Again, good luck...
Depends on the predator. Bears don't care about electric fences if there is an award on the other side (except maybe young bears). If your coop is secure enough to make tearing it apart to get inside not worth the effort, you don't need the electric fence. If your coop is easily breached, an adult bear will walk right through it and rip the coop apart.
Wire fencing is worthless against bears too. Thats one of the reasons why I have always free ranged. Why keep making repairs again and again? Instead, make the coop as resistant as possible and keep them inside it at night. Its been that simple for me.
Obviously, this is all moot if you dont have bears in your area.
Generally speaking, my dog (probably his scent more than anything) is enough to deter most daylight predators. As an emerging homesteader, there is also a lot of daytime activity around the house that also helps.
The breed matters. Larger breeds are more formidable prey. It takes larger or bolder predators to attempt to tackle them. I keep brahmas and I believe that is why the hawks and owls watch intently but have never attacked. A 10-11 lb rooster is a force to be reckoned with by a 3-6lb hawk. Not saying it isn't possible, but predators weigh the risks too.
Point is there are many factors that lead to success free ranging and minimizing losses. One should not be afraid or discouraged from doing it just because of potential predation or consider fencing their yard like fort knox to protect their chickens. Yes there are risks and yes losses will eventually occur but that is also possible in fenced runs. If you choose to free range, the risks are higher and cant be ignored, proper precautions must be taken, and the potential for loss must be recognized and accepted. If you can't, fence them in a run, but the potential for loss is always there. How many posts are on here about predators breaching runs and coops? So personally, id rather them be free.
Purely my humble opinion.
