My front door has a deadbolt, but right next to the knob/deadbolt is a tall narrow window, so that you can see whoever is outside. This is a security risk as anyone could smash that window and open the lock from the outside.
Is there a way to secure a door like this, without removing the window? The one idea I know if is a deadbolt where you need a key to open it even from the inside, but I don't think our code allows this for the front door.
