What kind of sensor bars I can use with Dolphin and how to connect those?

[Kosmos]

As I see, there is different kind of sensor bars available on Ebay. There is some wired with strange USB type cable and some wireless. What I can use with Dolphin? Where I should plug that weird USB cable? Is it into my PC? If yes, then I need to pair that bar like we do with Wii Remote? And what to do with wireless bar?

Any kind.

Any device that has power. You can plug it into the PC that is running Dolphin, or a different PC, or a Wii, or a power bank...

No, you just have to plug it in. A sensor bar doesn't communicate with anything, it just emits some infrared light so that Wii Remotes can see where the screen is.

Put in batteries and turn it on.
