Being that this is a privacy matter, if you are on the ground floor or in an area where people could be looking in, keep the blinds pulled when it is after dark. Make sure to check around and to call your local officers if you think there are people out there doing that. You can also call your neighbors and see if they have had anything like this happen or if they have noticed anything suspicious. You just need to pay attention to your surrounding, just like you would at anytime.
