start & stop system (eco mode) electrical question




I guess this system has a fuse somewhere, but I can't figure
out which one it is.
this diagram does not mention it specifically:

the reason I'm asking is because I hardwired my dashcam
to the fusebox in the engine bay, and I get the impression that
it's taking power directly from the start/stop battery...
I wired the camera on fuse 7, of which the diagram says: "starter 6,7,19,27"
This morning the eco function was not working, nor could I switch it on
myself, which i guess meant that the battery was empy..
(after a 40 minute drive & a restart it worked again)
Although even IF the camera is taking power from that battery, it
should switch off by itself when the voltage drops below 11.7v,
in order not to drain completely.
