I tried accessing Live View but the app only shows a black screen.
Some customers may encounter a blank live-view screen when setting up. If this happens to you, try switching to airplane mode first, then reconnect for a network refresh, and it should be fine from there.
Moreover, another solution is to double-check if you have updated the latest version of the VIOFO mobile app. If not, please do so, then switch to airplane mode.
Is there another way to view my footage?
You can always review the footage on the built-in screen itself on the VIOFO(If you have a model with a screen), or take out the SD card (with a microSD reader) and play it on a laptop or PC. While VIOFO doesn’t have a dedicated web viewer, we recommend the Dashcam Viewer software.Most VIOFO cameras also ship with a short USB power cable, which can be used to connect the camera directly to the computer, sending the camera into SD card reader mode, with all footage viewable through the computer, same as if you connected the SD card directly.
Dashcam Viewer is available for both macOS and Windows. Download here.
