Ecamm needs local network access for features such as:
NDI
Network Cameras ( via RTSP )
Elgato Stream Deck support (via the Ecamm Stream Deck plugin)
The following message will show up when launching Ecamm:
Choose Allow when prompted, or these features will not work.
If you’ve seen this prompt and have already chosen Don’t Allow, you can grant this permission by enabling the toggle next to Ecamm in the Local Network section of the Privacy & Security control panel in your Mac’s System Settings application.
