This study was aimed to develop a planning method of CCTV cameras surveilling juvenile victimization to school crimes. With spatial settings of school common spaces, evolutionary algorithm was applied to implement the planning method for accommodating numerous variable compositions. The required variables, their initial conditions and boundary conditions were derived from the theoretical exploration on precedent research works. The applied evolutionary algorithm used a search method with tracking fitness factor. The fitness factor of the implemented algorithm was calculated from standard deviation of distributed non-surveillance ratio and shadow area ratio. The overall algorithm utilized, as computational parameters, the camera layout information including each camera’s position, panning angle and tilting angle under the initial and boundary conditions. Finally, the developed method enabled CCTV camera layout schemes, surveillance areas and the quantitative results to be generated by the heuristic search process. This study also showed method applicability to school settings especially focusing on indoor common spaces.
