OneLINK is a part of the Vaddio Cat. 5e Structured Media Cabling Standard for video, power and control over Cat. 5e, with one important difference: the OneLINK system passes power to the camera over Cat. 5e and provides a bi-directional control channel for RS-232 communication transmitting/receiving uncompressed digital video up to - and including - 1080p/60Hz all on a single Cat. 5e cable. The system is made for 12 VDC PTZ cameras with digital outputs (HDMI 1.4 or DVI with HDMI adapter) that use RS-232 for control (i.e. TANDBERG® Precision HD and Precision HD 1080p PTZ cameras).
