Happens usually after power outage.
Seems this is also written in the log ->
2023-01-26 08:36:54 | default | Save Config | Saved config. IP:Local Login Username:default Group Name:user Channel:6 Channel Title :Sisä-->Channel6 | | | | | | | |
2023-01-26 08:36:50 | default | Save Config | Saved config. IP:Local Login Username:default Group Name:user Channel:1 Channel Title ääportti-->Channel1 | | | | | | | |
But, looking at the playback, Pääportti doesn't change to Channel1 that time, but Sisä changes to Channel6. Pääportti is IPC-HFW2431T-ZS-S2, Sisä IPC-HDBW2231E-S-S2-0460B.
