The document discusses an automated enforcement system (AES) used in Malaysia to monitor federal roads and highways using cameras. It then describes a Windows Phone app called AES Camera Tracker that uses GPS to warn users with speech notifications when they are near an AES camera and displays a map and list of camera locations. The app runs in the background and provides speed readings, distance to the next camera, and information about how the AES system works to help users understand it and get warned before passing cameras.
