A recent utilization study of the closed circuit television system conducted by the Visual Education Department, Medical College of Virginia Campus, Virginia Commonwealth University, revealed that most of the videotapes were played to the three major campus educational buildings. As a result of the study the university will continue CCTV service to classrooms and laboratories in these high-use buildings. However, in an effort to cut costs and manpower, TV self-service has been implemented or increased in three locations.
弗吉尼亚联邦大学弗吉尼亚医学院校区视觉教育部最近对闭路电视系统进行的一项使用情况研究表明，大部分录像带都播放到了校园内的三座主要教育大楼。根据这项研究结果，该大学将继续为这些高使用率大楼的教室和实验室提供闭路电视服务。然而，为了削减成本和人力，已在三个地点实施或增加了电视自助服务。
