So no solution. Physical requirements are what they are. I'm used to IT forums where they might suggest an alternative, but they will advise how to solve within constraints stated.
I just love these posts that don't respond to requirements of the poster. If you don't like WiFi explain to the OP how to get the stream back w/o pulling Ethernet back to his switch.
Just purchased this camera and I see that the camera interface depends on Adobe flash for video display. Since Adobe will no longer distribute Flash starting in 2020, is there a firmware update that doesn't have this dependency?
