I would like to know where you run your OpenCV script (which transmits the RTSP stream of the camera via MQTT)?  
For Node-red, I understood that it connects to the MQTT Server and displays the video stream.

yes I think like you. By adding more complex functions the RPI begins to saturate. That's why I also test [[ANNOUNCE] Node-RED Desktop v0.9.1 Released](https://discourse.nodered.org/t/announce-node-red-desktop-v0-9-1-released/12247) for Win10 or MAC. Node-red with the power of a PC 🤩
