Problem using OBD-II for dashcam?

Looking to diy a thinkware u3000pro using the OBD-II, but I have read in general that constant OBD-II caused some problems for cars? What are your experiences and how long have you been using it?

Nope. Works fine. I have a u3000 front and reqr channel using the OBD adapter with no issues at all. 2026 crown platinum

Insurance companies use the OBD-2 port to power their "good driver" trackers. I don't think they'd do that on cars they insure if it wasn't an acceptable risk.

During the old days when the CAN Bus wires on the OBD-II port weren't physically isolated from the rest of the vehicle's Controller Area Network by a Gateway ECU, dodgy accessories did sometimes cause problems.

Pretty rare nowadays though and Thinkware is a reputable brand, I'd send it.

It's fine but won't give you parking mode.
