Access Media Sources with Automation

Hi All,
I use Doods to email a Photo when a person is detected this is triggered on motion detection form my Reolink RLC-520 I did it this way to take the load off of my Pi4 and it works well, I also save a video of the event but there is too much lag before the recording starts.
The Reolink cams show up in Media Browser but I cant work out how to access then .
My question is how do I access the Reolinks via Automation

Thanks Garry
