    Hi Gijs,
    U1 is sufficient, U3 is better (is faster). But besides the U-number, the video speed class mark is also important.
    Have you already formatted the SD card using the Innovv app? It is recommended to format the SD card with the app and not with a computer.
    In the app, do you see that the cameras are working properly?
    If the firmware update went well, you can see in the app under settings which firmware the K3 has. This is under System. To be sure, you could perform the firmware update again if you have any doubts.
