If I have an existing OBD connection to the SafetyCam, can I remove the SafetyCam and plug it into another vehicle? Will it still work as usual?

The SafetyCam and the OBD work in pairs, you can set up the SafetyCam in another vehicle provided the OBD and the Safetycam are mapped on the Azuga Web application. If these are not mapped, the SafetyCam will still work and record videos but the events will not be generated in the SafetyCam.
