At NAB, BHV Broadcast is launching a significantly enhanced new version of its power solution — Video Ghostdx. It now extends from cameras and monitors to include PTZ heads, or any unit or application requiring a reliable power source and data link.
BHV Broadcast said Video Ghost, the video equivalent of audio phantom power, is known in broadcast for its method of transporting power and SDI video over a single coaxial cable. Updated to Video Ghostdx, the system now allows the simultaneous transmission of digital video (SDI), DC power and bi-directional data over a single coaxial cable.
Supported formats include SD and HD, and it is 3G/6G/12G capable to achieve up to 4K Ultra High Definition (UHD). The data control link is compatible with numerous protocols including Sony VISCA, Pelco-D and Pelco-P, and can control PTZ (pan/tilt/zoom) functions remotely as well as color correction and iris settings.
Video Ghostdx now offers up to 75 watts of DC power over 500 feet for use in hard-to-reach locations without the added implications of running local mains power. A built-in proprietary interlock system prevents power being sent over the coaxial cable until the base station has established contact with the head end, thus avoiding any accidental damage.
Video Ghostdx will also available in a rack-mounted version, GhostRackdx, offering four channels of power over coax in a 1RU x 19-inch rack case with integral power supplies and front panel monitoring. GhostRackdx is ideal for OB vehicles and can be run over passive jackfield systems.
