Ask a Question
  • I just ordered this, hasn't shown up yet, but I've been reading the manual for it. I'm trying to confirm that if while in parking mode, will the footage recorded with the motion detector be saved in the non overwrite section of the sd card?

    Yes, dash cam and the g-sensor setting will save the footage from being overwritten.
    It's on page 15 of Viofo A129 pro duo manual if you are looking at the same manual.

  • What kind of warranty is on this?

    Capture Your Action provides a one year warranty and unlimited support.
