A/V over ethernet?

[David Schwartz]

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.

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.
