After several months of trying different options, here is my live streaming setup in a case.
Atem mini pro and 10 inch monitor and even runs completely off battery power, if needed.
This addition now means I can live stream a funeral from a grave side or in the open air, with multiple cameras, all switched from this small case.
First use was this week at the Catholic Church in Dorchester. So easy to setup and helps to keep my presence as discreet as possible.
