Notes on using PTZ Network Cameras with built-in slip ring

Updated in September 2023

A PTZ network camera with 360 degree endless panning has a built-in slip ring that can transmit power and signals.
If the slip ring is not clean due to dust etc., noise or connection issues can happen during the pan (horizontal rotation) operation.
