I made some tests that you may try
- Take your rtsp stream and produce jpegs that you publish to your MQTT broker and then subscribe and present them on the dashboard
- Take your rtsp stream and produce a mp4 playlist, then make it available via https and present it on the dashboard. How to do this I'm not able to do myself, maybe @kevinGodell has some insights. Anyway this would mean you would have to open up a port in your FW for the https server so I'm not sure you are willing to do that
The first example could look like the below (here I'm using a public available MQTT broker, test.mosquitto.org) and this would not require you to open any ports in your FW. If you select a good FPS it will provide a pretty useful solution
