@dalias. Mostly via mobile app but I can connect an RTSP stream to things like Synology Surveillance Station recording setup or TV or other things*. If it's ever slow via mobile phone (happens v occasionally) I just switch on Tailscale on my phone (my router is an exit node) and it's as fast as if coming from cloud (I have a gigabit fibre connection).
