I’m looking to power (and transmit data to and from) the cam from distances greater than 50 ft. How can I best boost the UART/USB/SPI to RS-485 levels? Or is there another better way to go about this?
I’ve found a few things that may help. Curious as to what anyone thinks in terms of which may work best.

PoE possibly? The original idea for the project was to make the camera PoE-enabled, but to be honest I’m struggling mightily to accomplish this. I’ve had a few ideas, like using a PoE Network switch and then mounting an ethernet port on the board, but I’m not an experienced prototyper and don’t know how I’d do this.
