To use the camera on the 3G/4G mobile network, you just need to make a port forwarding on your router. This is the only part that can not be automatic because it is done on your router (if you have one). If you have any configuration problems, please email me. There is a contact option in the app menu to open a ticket easily. If you like this app but the ads bother you, there is a paid option in the app that removes them permanently. This, along with the ads, helps fund development, thank you for your understanding.
