I have a Lorex NVR with 7 wireless cameras and recently also purchased a Lorex floodlight camera and 2 wireless cameras. The Lorex NVR can detect those wireless cameras but can not add them. I searched Lorex website and seems a Fusion NVR would work with them. However, since these wireless cameras are just for backup only and I do not want to get another NVR just for these 3 cameras so I am wondering if there is a software similar to Dahua smartpss that supports these wireless cameras. I have a desktop sitting around and if I can install the software just like SmartPSS and PC NVR so I can do 24x7 recording on these cameras. would really appreciate any suggestion to achieve this. Thanks!
