UMass Amherst implements a multitude of services to ensure safety on and off campus for all students. On-campus residence halls are constantly monitored and secured. There are cadets stationed at the entrances that monitor the area while students are signed into the building. Anyone who does not live in that specific building has to be signed in by a friend with legitimate identification to ensure the safety of everyone in that residence hall. In addition, there are about 350 security cameras constantly monitoring every residence hall and the doors are always locked. The only way to enter is with a student ID registered to that specific building.
