Hello,
You might have an issue regarding the index of your camera set in the opencv config.
You say using the kinect as well, kinect has also a camera and maybe Windows recognizes the kinect camera as index 0.
Try setting your camera index to 1.
Also make sure you have isOpenCvActivated=True
Regarding the error with no battery detected is not a problem.
It is because you are running a desktop PC with wall supply instead of a laptop or tablet with battery.
If I remember you can stop publishing the error by setting health check to False:
