Why does it say “Please insert SD card” or “No current video” after I’ve inserted the SD card?

First, please check whether you have inserted the SD card into the camera correctly and recognize it, when recognized successfully, you can see the option of "memory card storage" in the camera settings.

If the SD card has been successfully recognized, check that the memory card storage is turned on and the relevant recording mode is selected so that the camera can automatically record video that can be viewed in “Replay”.

You can follow the steps below: Open the APP, click on the camera settings, select the "Memory card storage" option to choose the recording mode or set the schedule.

If the SD card is not recognized when inserted several times, it is recommended to format it once and try it again or replace it with another SD card.
