The duration of video that can be stored on the DVR depends on whether you are recording in standard or high definition.
Most Race DVRs have a 500 GB hard drive. That amount of storage will hold about 150 hours of HD or 300 hours of SD video.
Press the red 'C' button below the Guide button on your Race remote to access your recordings. In this screen, the 'Home' percentage at the top of the screen will show you how much of your storage has been used.
Note: The 'Network' percentage refers to Cloud storage and will ALWAYS say "100% Full."
