Opening a door is considered an output because it is an action that results from a decision or command to allow entry or exit. The input, in this context, would be the intention or motivation to open the door, such as wanting to enter a room or leave a space. Thus, the act of opening the door is the outcome of that input.

Even the police can come to your door, and have to knock or ring the bell to present you with a search warrant; or with a summons.
Because it is excited to see who is there :D
