Without going to each camera in your dashbard individually, your best option is doing the API like mlefebvre suggested with that many cameras. I would highly recommend maybe using TAGS on the cameras that have it because you are right, there is no way currently to show a list of cameras with MV Sense (or even MQTT) enabled in dashboard today. Hoping we can do something in the Camera List View where you currently can filter on MV Cloud Archive and which cameras have it enabled or not to atleast give some sort of filtering view. I have brought this up with the product team.
