Same for me Pat. I am on Mojave 10.14.2
I have tried all the solutions provided here. The Mojave plugin Luca mirrored, or the newest on Foscams website, it is all not working. I took out fsIPCamReg.bundle from library/internet Plug-Ins and saw that all those installers do not install anything in here. Changing location for the installation on my external disk, it installed those two files

FosIPCCore
FosIPCCoreManager

(no extension, system says they are exectutable unix files) and it created a "usr" folder on that drive and stored those unix files inside it in "local/bin" folder. I tried moving those files into library internet plugin folder, but to no effect. My camera login page still expects a plugin to be installed and does not log in to the camera.

I would be fine with FoscamVMS software, if it would be working properly. It does show the feed and basic controls, but "Setting" brings up an empty black window, so I am still not able to do any settings on the cameras.
