Hi Peter,
I have a bus operator in the UK who uses the CCTV system to record cameras and a codec board to generate On-board advertising that displays on 17" passenger screens.
The system uploads new advertising files and downloads CCTV footage via WiFi in the depot.
Do you want to link adverts to GPS locations? ie advert for McDonalds appears on screen 100 meters away from the next bus stop, which is outside a McDonalds outlet.
Do you want to provide AVL (vehicle location reporting)?
2-way driver communication can link throught the ticket machine (Wayfarer200 ETM)
What country is this application for?
