First of all, thank you Carlos for your answer. Perhaps a more complicated question. For the same product, the answer to the question about backing up the data was that you can set the PC client to back up the videos to the NAS. But this only applies to the videos that I record manually, I assume. In my case, a video is started every time motion is detected, but this data is only available on the SD card. If the camera is dismantled with the card, I will of course also miss the videos, because I haven't recorded anything manually. Maybe someone actually has a solution? Or, to put it another way, how is it automatically recorded on the PC every time motion is detected? With many thanks and greetings for feedback Marc
