As a complex of material and spiritual, space and society, the university campus is a relatively complex environment. This paper investigated the effectiveness of the third generation of Crime Prevention Through Environmental Design (CPTED) in reducing crime and enhancing security within educational institutions. The third generation of CPTED emphasizes the integration of advanced technologies, such as access control systems, intelligent sensors and alarms, emergency communication systems, data analysis, and predictive policing, using advanced technologies to enhance security measures on university campuses. This paper aimed to explore the current security level of the university campus, interpret the principle of the third generation CPTED to reduce the crime rate on college campuses and propose a security strategy based on the third generation CPTED for the university campus. The research method of this paper was qualitative, conducting semi-structured interviews with campus security personnel, university administrators, university teachers, and staff of the Universiti Sains Malaysia, using NVivo software, and using thematic analysis methods for data analysis. The findings suggest that traditional campus security measures may not fully address the evolving security challenges facing modern universities. Participants expressed concern about inadequate lighting, limited surveillance coverage, and inadequate emergency response systems. The results of this paper emphasize the technical application of the third generation CPTED, thereby highlighting the practice of the third generation CPTED in university campus security, proposing the basic strategy of a smart campus, and establishing a mobile phone application on the terminal. Strong use of technology to facilitate real-time communications, incident reporting, and emergency response to enhance campus security and ultimately improve the overall security of the university campus.
