you have two cameras, i think you want to switch the cameras' videos from Cam1 to Cam2, from Cam2 to Cam1. If so, there are two ways: 1) use software, such as OBS, Vmix. use RTSP or NDI protocol stream to OBS or Vmix, and then, stream the video to video platform(such as KZfaq) from OBS/Vmix 2) use hardware: HDMI video mixer switcher. This model support 4K 60fps, if you want to get a HDMI video switcher, you'd better get at a better one which can support HDMI 4K 60fps. you can also write us for more details.

The controller joystick only has PTZ control function, control the cameras' movement.
