On-board devices are used for driving monitoring. They support live view, playback, remote configuration, alarm notification, GPS data collection, GPS positioning, etc. With on-board devices, you can not only get the GPS information of driving vehicles, but also set fence rules and deviation rules to regulate vehicles' movements (the platform will generate an event if any rule is violated). On the Web Client, you can manage on-board devices, including adding, editing, deleting, and remotely configuring them.
