Agreed that most thing do power down after switch off, but that fuse panel will have live feeds, otherwise things like your key fobs wouldn't work.The answer to that is NO.
I have my dashcam hard wired via this fuse box, as do the above posters.
Kia does not turn the power off to many things straight away. It can be up to 5 mins before some power down.
I think all the fuse switch does is isolate all the wiring (guess it activates a relay in the main fuse box that cuts the live feed from the battery), so in case something is still on, such as dome light.
