How to send live performance synced A/V from our dining room to our bedroom

Hi, I was a professional audio engineer for 25+ years and have done some FCP editing on personal music video projects. But I’m new to OBS. I need to be able to record live music performances while tracking in the vocal iso booth in our dining room recording studio, and send at least one live video signal (preferably 2 or 3 camera’s video, eventually) in sync with the +4db balanced stereo output from our UA Apollo interface (which can be necked down to -10db balanced/unbalanced if required) from our dining room studio control room, where the iso vocal booth and the recording equipment live, locally to our master bedroom 22’ away only.

I need to do this because my severely disabled wife is pretty much stuck in bed for the rest of her life. And the only way to have her be able to participate and be involved is to figure out a way to send at least one video signal with the studio quality audio from Logic 11 via our UA Apollo audio interface in sync - or at least close to being in sync - with the video signal from our dining room studio to the bedroom.

I already have HDMI cables run and an HDMI DA, four separate gigabyte Ethernet routers distributed throughout the house, and Cat 6 wire run everywhere throughout the house, including and especially the dining room and the master bedroom. So if I could marry the audio and video in OBS and get it to come out of one of the Thunderbolt outputs of my M2 Mac Studio, and convert that synced output signal to HDMI using an adapter, which I already have, then I could just send that signal to our HDMI DA and it would go to the bedroom, living room home theater, and the family room TVs and receivers automatically.

But it would be even better if I could send or share that synced A/V signal to my severely disabled wife’s 1st Gen 11” iPad Pro A12X Bionic 2.5 GHz processor, so she could watch the video on her iPad and listen to the audio using her AirPods Pro!

It seams like what I’m hoping to be able to do might be possible. And I think I can figure out the setup part of it. But I don’t know how to “stream” video - preferably captured with my iPhone 13 Pro - in sync with recording quality audio out of our UA Apollo audio interface, from one side of our house to the other using our LAN.

I’ve already set up OBS to use the UA Apollo for audio input. And I’ve successfully set up my iPhone 13 Pro to be used as a webcam. The only missing piece of the puzzle is getting the synced A/V from the dining room to the bedroom.

Any help pointing me in the right direction would be greatly appreciated! And it would increase my severely disabled wife’s quality of life in ways that I could not even begin to describe. Thanks for your help!

I need to clarify that on top of the four mics I have connected to the Apollo hardware audio interface I also have Logic 11 output routed into UA Apollo Console macOS app via two of the Virtual channels UA Console offers, as well as the output of our Axe FX III AND Mac system output as well, routed into Apollo Console app, and that all sound I’m trying to send - or “stream” - locally is being mixed in Apollo Console. So, what I should be sending to OBS audio input is the sum/mix of everything that is going into UA Console and NOT just the mics connected to the Apollo inputs. I need to figure that out as well - I might have to contact UA tech support to ask how to route the mix coming out of the Apollo interface into OBS - from within the Mac Studio itself, not physically out of the Apollo hardware. Because to do that - using the physical outputs of the Apollo audio interface - it would seem I would need some sort of box to physically route the outputs of the Apollo into OBS?!?

Again, I only need to send that mixed sound with video from my iPhone - as in sync as possible - from our dining room to our bedroom. Is “streaming” locally over our LAN WITHOUT a streaming service possible to do with OBS?
