A surveillance camera includes a slip ring having electrical connections for Ethernet protocol signals and a RF reference plane. A first circuit is located on a rotating portion of the surveillance camera and electrically connected to the camera for compressing signals generated by the camera and for converting the signals generated by the camera to Ethernet protocol signals. The slip ring has a stationary portion and a rotating portion, each with a corresponding plurality of electrical connection. An RF reference plane is located on the stationary portion of the surveillance camera and electrically connected to a first subset of the plurality of electrical connections of the stationary portion of the slip ring. A second subset of the plurality of electrical connections of the stationary portion of the slip ring conducts the Ethernet protocol signals and is arranged in alternation with each electrical connection of said first subset.
