The remote control panel (RCP) can operate over a considerable distance to the CCU via RS 232 (and up to many km using the fibre link) and can control up to seven RubiCam camera heads. The RCP controls zoom, focus and iris as well as the full electronic parameters of the camera, making it suitable for an OCP position vision control area in a studio or an OB truck. Furthermore, with the Embedded Audio option, the CCU can accept two audio or data channels which are embedded in the HD-SDI over coax or, with the full duplex fibre port, over SMPTE fibre camera cable. There is also a return path for video and audio making the RubiCam camera system especially suitable for all studio productions and remote commentary camera positions where space is often limited and reverse video and talkback are essential. RubiCam is equally well suited for mobile applications by land, sea and air.
