A:Answer Hi Rico! While the dash cam does not have specific night vision features, it can certainly record at night. The recording time before the dash cam overwrites itself is dependent on the size of MicroSD card used. However, the 16 GB MicroSD that is provided along with your dash cam will store approximately 2 hours of footage before overwriting the oldest footage to make space for new footage. Since the dash cam does not have a built-in Wi-Fi feature, users will not be able to download footage and send to their emails directly. With the X500, users will have to eject the MicroSD card and insert to their computers first in order to do so. Please look into the F750 and X350 models that are both available at Best Buy with the built-in Wi-Fi feature if you would like have immediate access to your footage!
