Like user BrianUsher with his Dericam S2C, I was able to get my Topodome TD-S21C (https://www.topodome.com/productinfo/612509.html) working by using Monocle’s gateway and adding @tunnel and @fake-fmtp tags.
These Cams have some similarities in terms of RTPS URL and Audio Codec.
To cite BrianUsher:
“Use /11 or /12 at the end of the RTSP URL for the first or second streams respectively. Audio is set to G711 and works perfectly.”
