Yes, I'd say this is the norm nearly everywhere I've been -- although I've mostly only been to universities in higher-income countries. There are occasional exceptions; for example, the American University of Beirut had manned gates, although the guards usually just let people walk through. The one common exception I've seen is libraries. For example, at the main library at the University of South Carolina, there is a gate, and you have to either swipe your campus ID or register as a visitor.
