@joseph_1979 i've found the reason. If more than one device connected to the camera ONVIF port, than the user logged out by the camera. That's not good and other Reolink devices not do that. I think it is an issue and must fix by Reolink.

Hi, i have an new Trackmix Wifi. I also have doorbell, E1 Outdoor and E1 Zoom. I see every 3 minutes the Trackmix Wifi lost the login credentials and disconnected and i have to relogin (happens with app (Android and Windows) and lokal web). That happens with the Synology Surveillance, too! Every 3 minutes i have no recording on my NAS. The camera also ignores saved monitorpoint and go to an default direction. If i click in the app on the second present and after that to the monitorpoint, everything looks fine. It seems the camera had an softreset every 3 minutes.

Kind regards Peter
