Hi! This is always difficult and webcam 7 is a little bit limited when it comes to adding a new IP cam using rtsp which is usually the easiest way to add an IP-cam nowadays. Try to use an existing template for the same brand and see if that works which it do sometimes. Then you can try to add the cam as an Other source with http:// A quick look in the manual for the cam gives several ways to connect that you can test.
