Multiplex a CCTV feed with Xfinity X1
Is it possible to take the (HDMI) output from a CCTV NVR and multiplex it so it is viewable on all the Xfinity X1 connected TVs in the house? I know i did something similar many years ago when OTA/cable TV was simply an analog signal through coax, but now with Xfinity and the digital services, everything is far more complex. I figured i would need to buy a compatible multiplex device, and connect the CCTV HDMI output into it, as well as the incoming coax from Comcast, and have the output split to all the TVs in the house. Ideally, a single channel could be used and when any of my xfinity connected TVs go to that channel and the feed from my CCTV NVR would be displayed.
In case it helps with suggestions, the Xfinity X1 hardware i am using is:
* PX013ANM - Main Unit
* Pace PXD01ANI - Additional TVs
My Video Camera NVR unit is:
* Reolink RLN16-410
Thanks for any help/suggestions
