My company writes smartphone apps. One of our apps needs to know definitively if a vehicle is in motion. We use gps and the accelerometer right now, but we'd rather get it right from the vehicle because it should be more accurate and will open up new opportunities to create value. I have found and acquired devices for cars, but I can't seem to find anything for trucks and I have a request from a company with 20,000 trucks. I would appreciate it if someone could point me in the right direction
