Your WiFi connection should already be set up by WPS or by the installation wizard. Use the WiFi scanner to connect your camera to a different WiFi network. Or use the scan results to check the signal strength at the camera´s installation spot.
You have two ways to access your camera over the internet - the easy way is called. The only way to get complete access to all your camera´s functions is called DDNS. The DDNS or Internet Address gives you access to your cameras web user interface.
To use the video FTP Upload, you first have to set your ftp server address and login credentials. E.g. you can use your routers FTP service as FTP Server - in this case simply put in your routers IP as the FTP Server address. If you set up a FTP server on a local PC (for example with Filezilla Server), use the PC’s local IP address.
The UPnP standard is supposed to make your life easy. Every port that is needed publicly by a device on your network will automatically be forwarded. This would make the DDNS access to your camera very easy...unfortunately it often does not work and might be considered a security hazard by your network administrator.
