Sony a7s live feed setup

[aikia]

I’m adding some live camera feed scenes to a show, and decided to use a Sony A7s for it - since I already own one.

Got a Blackmagic UltraStudio Recorder 3G and it seems to work very well. 
Also, purchased a dummy battery not to rely on these tiny batteries that end up empty in ZERO time. 

In the context of a show, though, where I’d setup and check all connections, and then be back to it after a longer break (during which I have no access to my setup), right for show start, is there anything I should be aware of? Like : things that could go wrong? 

Camera settings that make it shut down after some time? Standby? Overheating??? 

What’s your experience?

Thanks!!
