Thats a textbook concentration camp. You are correct in your descriptions and distinction from extermination camps, concentration camps are not that rare even these days around the world in troubled places.

They are as name suggests just to herd bunch of people behind the fence, not much more. Of course, the reasons are usually far from nice and thus due to at most OKish treatment even there some sad things happen due to amount of people crammed together for a long time.

In Europe during WWII we had tons of concentration camps all over conquered Europe but only few were actual extermination ones, usually converted/expanded from concentration ones. When allies were coming nazis often turned concentration -> extermination due to orders given from above.
