yeah sorry I meant in more general terms not in the camera case - like I said the power pins on both make sense and is what I sort of assumed was going on in real life.Ah. The cams don’t use the ports to communicate with the vehicle. The obd2 ports have a power pin, a ground pin, and a pin that gets power when the car is turned on. The cam uses those pins to get power and determine if the car is on so it can determine when to go into power saving mode. Wikipedia has some good info on how obd works if you want more info.
just strange to me that the cable doesn't just fully wire one side and partially wire the other and mark one as "data" and one as "power" so that you don't try to run two data devices on the cable at the same time. probably just not worth their time to bother.
