A daily escort van service is available during the evening hours (5:00 pm - 3:00 am) to pick up and deliver students to any campus parking lot or other location within a one-mile radius of campus. Vans leave every half hour from the Eisenhower Library. Walking escorts are available by calling extension 8700 from any campus phone or 410.516.8700 from an outside or public telephone. Push button security/escort phones, located in several campus buildings, can be used to alert security officers of an emergency, to request information, or to summon the escort van. Emergency telephone stands with blue lights, which connect directly with the security office, are located strategically at 14 locations around campus. These telephones open a direct line to the security office as soon as the receiver is lifted or the button pushed. To ward off a possible attacker, an alarm sounds at the phone. Pay telephones also are available in most campus buildings. Security officers also patrol parking lots Garland, Clark, and Stony Run from 3:00 - 11:00 pm, Monday through Friday. Student monitors, wearing bright orange vests and carrying radios, patrol the upper and lower quads during fall and spring semesters. To reach the security office, call 410.516.4600. In case of an emergency, call 410.516.7777.
