I thought I had mentioned a voltage inserter but I may have been thinking of another forum, with similar questions that I posted in. Sorry about that. In theory, the voltage inserter should work but I don't know if there will be an issue with the active hybrid fiber cables or not. I guess all you can do is connect it all before installation and then thoroughly test it out. However, with the use of conduit, as you well know, that makes for fool proof cabling.\n\nThe only thing that makes me a tad bit nervous about the voltage inserter (and I've read some very favorable commets from actual users and not just the mfr's marketing) is having a direct power connection via the adapter to the HDMI input. Power spikes\/surges etc would make me probably over cautious but I guess it wouldn't be any different than a spike originating at a source and then travelling down the HDMI cable.
