Why not route it in a wire channel(basket) as a PLTC cable? There would be a need for a cable gland - Crouse-Hinds CGB, or similar - on the purged end as it only required to maintain, contain the pressurization and minimize airloss. On the other end, if the camera is trully XP rated that requires the potential explosion to be contained within, then a seal fitting should take care of the business. If you are thinking of splitting the power feed and the signal(Ethernet) feed into the camera body, feed the power conduit and the Ethernet cable into a condulet and couple that into the camera body. When installing the seal, just remove the jacket where it is surrounded by the sealing material, from the Ethernet Cable, exposing single conductors/wires.
