An average speed detection system includes a first automatic license plate reader (ALPR) camera having an infrared camera for capturing identification information from a vehicle passing an entrance point. A first communication module is coupled to the first ALPR camera for transmitting the identification information and either an entrance timestamp or an exit timestamp for the vehicle. A second ALPR camera includes an infrared camera and an overview camera is coupled to a second communication module. The second communication module receives the vehicle identification information and the reference time stamp from the first communication module. The infrared camera of the second ALPR camera captures identification information from the vehicle as it passes the exit point, and if the time at which the vehicle passes an exit point is prior to an exit timestamp for the vehicle, the overview camera flash illuminates the vehicle and captures an image of the vehicle.
