Can I use Raspberry Pi WiFi connection for video streaming?

As far as I understand, streaming from action camera on drone board does with this camera separate WiFi adapter. Can I use the same connection as Raspberry Pi use for control ? And what camera can I use for this ?

The most straightforward to use is probably the Raspberry Pi camera or Logitech C920. You can stream video from them over Wi-Fi.

I recently found this:
