The camera started working on its own after about three hours. The Windows client app has a setting to add cameras automatically. It seems to work but it apparently takes hours to add the camera. There is nothing to this effect in any of the support articles. I guess I can consider this issue resolved.

@joseph_1979 The camera is not WiFi. It is PoE.

Replaced RLC-842A camera and now it won't connect. Old camera worked fine except messed up image. Replaced with new camera and it will not connect. Nothing else was touched on the network. Connection fails on Windows client and Android phone app.
