The WUUK Pan & Tilt Cam Pro requires an SD card in FAT32 format.
Update the firmware to the latest immediately after the pairing.
If you use a SDXC card over 32GB or a SD/SDHC card, after inserting the SD card, go to camera Setting> SD card, and tap Action Required to format the SD card to FAT32.
Note: This feature stars from iOS V3.3.17 / Android V3.3.12. And it works with firmware version 1.0.48 or above; you can go to Firmware Update to check the firmware status and upload it to the newest.
If the SD card status in the WUUK app shows “N/A” or “No Card”
It means there is NO CARD or the SD card is NOT RECOGNIZED by the camera. You can connect the SD card to a PC to check if it’s recognizable. Or try another available SD card.
