EJMT Abstract

Campus security is vital in providing a safe and conducive environment to students and other residents of a college university. However, the existing CCTV surveillance system in the Lower Campus’ dormitory areas of University of the Philippines Los Ba˜nos is inadequate in coverage and contains multiple blind spots. This study formulates the surveillance problem as an optimal camera placement (OCP) problem and implements a two-stage optimization framework to find the solution. The study considered a total of four cases. The three primary cases focused on CCTV placements at main entry/exit points. The minimum number of CCTV installation spots was 9, 10, and 11 for Cases 1, 2, and 3, respectively. The minimum number of CCTV cameras for all 3 cases was 23 cameras corresponding to the 23 streets in the area. The last case is an enhanced case where existing cameras in the area were incorporated in the model, where the minimum number of CCTV locations was reduced to only 6 additional locations. All of the CCTV surveillance systems obtained in this study provided improved surveillance by eliminating blind spots while using the minimum number of installation locations and minimum number of cameras, providing cost-effective security enhancement in the UPLB Lower Campus dormitory areas.
