PoE injector in the hybrid podium

This brief illustrated article explains what a PoE injector is, and how it functions as part of the hybrid podium assembly.

Conveys Lecture Recording signal from Camera to Mac Mini

The PoE (Power over Ethernet) injector sends electrical current through Ethernet cables used for data transmission. Compact enough to fit within crowded podiums and credenzas, it conveys lecture recording signal from the camera to the Mac Mini computer. Any similarity to the name of a certain 19th Century American author is entirely coincidental.
