I have an intercom and would ask what they want through that.
If they said there was some problem I would volunteer to call the police for them. If there is a real problem then that is what is needed. If they are up to no good then police need to be there. There is no real need to open the door.
Here is a news article that illustrates why I would not open the door in the middle of the night to a stranger.
