I cannot speak for @zsolt.toth.39 but most folks here, it seems, are having issues with the firmware working after it is successfully installed. A few have it work until the camera is rebooted but then it fails with yellow-blue alternating lights. Like the system will not connect to the network or isn’t able to read the credentials or the like. If you use the app to reinstall the camera, it will work until it looses power or you restart it. All of this is in reference to Cam V.2 or Pan Cam V.1.
I have personally reverted to the previous version of the firmware which works for me.
