Issue Description

We want to extend the length of the camera cable in this way. So we connected the camera to the Raspberry PI, powered by POE, and the computer could remotely SSH to the Raspberry PI, but realsense viewer could not connect to the camera through the Raspberry PI ip. Could anyone offer any help to get things working?

Hi @IvoryDai The link below has a guide to SSH'ing to a RealSense camera connected to a Raspberry Pi over a long ethernet-cable connection, including optionally using a PoE Hat, and accessing the camera data in realsense-viewer.

https://dev.intelrealsense.com/docs/open-source-ethernet-networking-for-intel-realsense-depth-cameras

This networking feature was removed from the RealSense SDK in version 2.54.1 onwards though, so version 2.53.1 or older would have to be used in order to SSH to the Pi from a host computer using this method.
