The central 3rd of the door seems to be the part which opens, seemingly sliding to one side?? Would that be automatic or opened by the small black knob or whatever that object is?
I also notice at 7.03 the side gate has a chain on it (night shot) but later on when the experts are viewing it by day discussing an abduction scenario they make reference to the gate having no lock on it. There is also no reference to the safety gate.I wonder if there was a chain there during the McCanns' holiday?
Yes the central third opens, IMO it hinges inwards electrically, operated by that control, and then closes automatically? It does not look like a handle. Would a child be able to operate it? If not then venturing further down street might be explained?
There were 4 of these controls IMO, one on each side of the outer and inner doors. In streetview 2015 the outside control on the outer door has been removed and replaced by a code keypad on the wall, but you can see a control on the inner door is still there.
