Police and security needs for events vary from short-term security presence for a guest speaker to larger events such as athletic, performing arts performances, road races, and VIP visits. Register your event with Police Services if you are uncertain at all about security/police needs for hosting the event. UNC Police reserves the right to determine security needs for any event hosted on campus. UNC Police services are based on the assigned officers overtime rate with a 3-hour minimum for each officer assigned.
