Why can't the Vantrue dash cam record videos in loops of 1 hour or longer?

The reason why Vantrue dash cam cannot record and save videos longer than one hour is due to the limitations of the memory card format. Most dash cams use memory cards formatted with FAT32, which can only support a maximum file size of 4GB. Videos longer than half an hour often exceed this size limit, preventing the dash cam from saving them as a single file.

What SD Card do we recommend?

We only recommend Vantrue, Samsung Endurance and Sandisk High Endurance/Max Endurance Card. To extend the life of your card, we advise to format your SD card every 3-4 weeks for regular everyday users and 2-3 weeks for heavy users to free up space on your memory card for new recordings.

Note: Samsung EVO Plus and PRO Plus cards are NOT recommended for use with Vantrue dash cam.

What to do if the dash cam shows "Card Error" or "Slow Card"

1. Format the SD card and update the dash cam to the latest firmware version.

2. Try a new recommended card.

3. If you have tried the above steps and the issue hasn't been resolved, please contact our support team via support@vantrue.net.

Why does the playback video have sound but no picture?

1. Please check if the video can be played back on the dash cam normally.

2. Please try to play back the video using the Vantrue player. You can download the Vantrue player from this link: https://www.vantrue.net/support/player

What to do if my dash cam turns itself on and off repeatedly?

1. Please check that the power connections are securely plugged in.

2. Power the dash cam from the USB port on the dash cam to check if it is the mount's issue.

3. Try a different charging cable.

4. Take out the SD card from the dash cam and check if the dash cam works well.

5. If the dash cam has a rear camera, unplug the rear camera and check if the dash cam works well.

6. Update the firmware.
