They will NEVER plug it back in! Do yourself a big favour and unplug all the cables to both cameras before you bring it in.They only disconnected mine when it said an impact was detected in parking mode. Don't care if they disconnect it as long as they do it with care and plug it back in. I wouldn't even notice, rather I am tempted to check the footage only if it gets disconnected.
Would they disconnect if someone were to use one of these: BlackVue DR650/DR550 Tamperproof Case for Front Camera
And be very careful as these connections are very fragile!
