There is this infrared camera installed in the hallway of my apartment building, facing the main entrance door and there is a 5 euro cent coin stuck on the door behind a piece of duct tape right where the camera is facing.
Can anyone explain for what purpose?
I don't know. Why did you put the coin there?
Dunno sounds like a jury rigged mag lock so when the door opens the camera switches on
Its a jew trap

it's to enhance precision of camera's motion detection alarm.

Wait, how does the motion detection alarm work exactly? Because it's the main entrance and people go through that hallway day and night.
