Thanks, but this is not what I’m looking for. “A/V over ethernet” not an “HDMI extender”. Dante from Audinate makes stuff that does this, but it’s proprietary and rather expensive. https://www.audinate.com/products/manufacturer-products/dante-av-video I’m looking for a more generic solution, if one exists. A lot of security systems offer them with WiFi cameras, and some use ethernet cables instead of coax. -David Schwartz > On Nov 5, 2021, at 2:19 PM, Stephen Partington via PLUG-discuss wrote: > > Here is a quick example of it.
