Security at a college or university is an issue that weighs heavy on educational institutions given the recent violence that has occurred on a number of college campuses. Consequently, schools have installed security cameras at many locations, including public spaces and common areas on campus. The public areas of dormitories, including hallways and exit areas would be areas that schools install hidden cameras. They are completely legal as there is no expectation of privacy in public spaces. It would be unlawful, however, to install hidden cameras in dorm rooms, showers, or bathrooms.
