They can arrest you for a dui even though they never saw you driving if there is other wits or a video. However, if they do after you have been home 30 minutes then they would need to ask you if you had anything to drink after returning home, if you say yes they would have no case. To arrest someone at home they must have a warrant or trick you into coming outside.
