Why is it that I have inserted the SD card and recognized it properly, but no video has been recorded?

Please check that the memory card storage is switched on and the relevant recording mode is selected so that the camera can automatically record video that you can view during "Replay".

You can follow the steps below: Open the APP, click on the camera settings, select the "Memory card storage" option and confirm to turn it on, at the same time, you can select the recording mode or set the schedule, which will be carried out in the set time, and the default is to record automatically around the clock without setting the schedule.
