The DVR I have is a Swann DVR9-Securanet. I have everything setup and can view over the internet using a PC but, not with my Iphone because of some incompatibility with the DxClient SW that is part of the DVR. I looked for apps at Itunes but, did not see any that said they would work with the Dxclient. The cameras I have are not IP cameras. Swann Tech support says they have a new 4 channel DVR that is Iphone ready but, they didn't have an app for the DVR9.
