HDCI

HDCI (High Definition Camera Interface) used in Polycom video conferencing systems. It uses a 60-Pin Low-force helix high-density connector interface.

Provides input for the main camera and second camera. These inputs support multiple formats in a single connector (Composite, S-Video, or analog Component YPbPr) and RS232 Serial PTZ control, using its own protocol (not Sony VISCA Protocol),
