Hi all, I remember seeing someone's dashcam where it had an overlay of the time/date plus what seemed to be a sensor input for when the brakes were applied, that it would show up an icon on the overlay.
I'm wondering if anyone knows the hardware/software to do such a thing? I have used Xport with minicam in the past which does GPS data overlay which I'd want as well as say brake light, turn signal and headlight icons. I'm guessing the hardware side could be a device that you piggy back the tail light 12V+ into each port and it reads when the car applies power to the lights? Something COM or USB? Does this already exist?
