Thank you for your reply.
1.) Suppose there is no SD card in the camera. Motion is detected and I can look back the records on my phone in the app.
If I want to look back on my computer where can I do that?
2.) I can not set NAS storage. I try to connect to my PC (not a NAS) with login name and password but it fails. Do you have any guide or something else what is wrong (maybe firewall, router settings)?
Thanks in advance,
