The SD card needs to be initialised before use. Check the SD card initialisation
status under camera settings on the app. If required, the app will prompt you to
“Initialise SD Card”. Follow the onscreen instructions to complete the process.
If this doesn’t help, check if the memory card is readable by plugging it into a
laptop. If not readable, try a new SD card.
DON’T FORGET! Before formatting, always check the SD card for any existing
recordings. We recommend backing up data via the “Video Recording” option on the
app. You can also copy the same onto your laptop/desktop
