I have a spare e-ink display and my next weekend project to follow onto this is to wire it up so it shows some faux "woodcut" images of birds detected, or something like that.

Also if anyone is interested, here is the server for the e-ink screen https://github.com/koryk/inky-impression-server
and here is a MCP for birdnet that I've been using for a bit https://github.com/koryk/birdnetpi-mcp-local-server
I’ve been unhappy with my little lcd board I’ve been using for the same here https://github.com/simonjgreen/OpenObservatory as the contrast is bad. I was considering using one of my trmnl displays, but it isn’t quite the right operating model for the frequency of updates I want.
Its very popular with friends and family, especially with older people that dont enjoy traditional tech.
Do you mean an RTSP audio only stream separate from the video+audio feed you might ingest to an NVR, or combined audio/video RTSP stream? Most manufacturers of security cameras with ordinary RTSP stream functions support provide both video and audio together. 'Frigate' for instance will auto detect audio stream on a reolink camera and it "just works" in the latest versions of Frigate.
