Hi, heshamk!
Good day to you!
It is recommended that you restore your camera to its factory settings.
Others: Try the following (but not necessarily for this model).
Use SSH to log in to the IPC as the admin user, go to the rm -f /usr/log/config* and rm -f /usr/setting/config* command, run the reboot -f command to restart the IPC and obtain the initial password HuaWei123.
Best wishes!
