Camera Confusion- Foscam 8910w

I have read many posts and am still pretty confused what I should use for the Foscam 8910W. Maybe I read the wrong ones and know there is a lot of info but I am confused.

Links to a Foscam plugin bring me to a VistaCam plugin. When I search on Foscam there is a separate Foscam plugin.

Also without any plugins installed if I add a camera manually, I can select Foscam (or VistaCam) by default

On top of it a Wintop Zcam automatically installs which I know posters have mentioned in previous posts. What are the differences and what should I use? How do I know what plugin is being used.
