The Vaddio OneLINK HDMI Extension System for HDBaseT Cameras is an interface that allows you to power, receive HDMI video from, and control your compatible HDBT camera using a single Ethernet cable up to 328′ long. The interface connects to your network for control, or you can use an RS-232 controller (not included) instead. HDMI video, up to 1080p60, is transmitted from your HDBT compatible camera to the OneLINK interface, from where it is available over a standard HDMI port.
