Computing Installation Parameters of CCTV Cameras for Traffic Surveillance

For properly installing CCTV cameras on any intersection point for traffic surveillance, some parameters need to be determined in order to get maximum benefit. The height, angle of placement of the CCTV camera is used to determine the view or the area that the camera will cover with proper resolution. The resolution should not be too high to cover less traffic and should not be too low to cover large but hardly distinguishable traffic.

This paper concerns with computation of the required CCTV installation parameters for the correct placement of CCTV camera. The simulation experiment has been done in ArcGIS to calculate different parameters and compare different computation results, and provide the necessary parametric specifications to install CCTV at a site. Viewshed Analysis is carried out to find the influence of variations in various parameters on the traffic images. Various comparisons are shown and best parameters are presented in results.
