Adding wireless to swann NVR systems

[john6174 0]

I recently bought a Swann NVR 8 channel system with powered ethernet cameras NHD818. I bought it with the intention of using the 4 wired cameras and then adding wireless cameras.On the Swan NVW485 Wi-fi cameras data sheet it says that "This security camera would only be compatible with a Swann security system using an NVR and not compatible with any other DVR system." I had purchased an NVR 8 channel system and so I felt confident I could add the wi-fi cameras later. NOT SO - SO FAR I HAVE NOT BEEN ABLE TO FIND ANY WAY OF ADDING THE Wi-Fi cameras. PLEASE HELP. ANY SUGGESTIONS -- thanks.
