That’s very old information that is from before the stream component became available.
I used to have my cameras configured exactly that way but I had the 10+ second delay in the lovelace card and only 1 frame every 10 seconds. If I clicked on it to get the detail view, I could get 1 frame every 5 seconds with almost real time update.
I still have some cameras configured this way for automatic popup on my kiosk tablets when people are spotted outside to give a slightly more realtime view… But not really very good with such a low framerate.
The guys above seem to have it working with the stream component, which means a good framerate of more than 1 FPS and realtime view in the lovelace card (at least from what it sounds like). That’s what I want. I already have 10 second delay with good framerate, so going back to 1 frame every 10 seconds isn’t an upgrade.
