ugging into the odb port is dubious. I will surelly never get close to this device. a usb or power socket version would look much more professional.

They're also using information from OBD for car power state, backup state, and speed (to turn the camera off when you're going 10MPH or more). For the way they decided to implement it, I think they've got a slick device. How they secure the data streams and communication with the dongle would be my big questions.
