I am renovating my recently bought house. It currently has a entry door system with a lock release on the yale lock so that you can release the door from one of the handsets. something like this.
I have handsets all over the house so I opened up the entry system outside (1 screw) to make sense of all the wiring and realised that I could short circuit the power and lock wire and open the door from outside.
I would have thought that it would be more sensible if the door release circuit was not exposed outside.
Is this how they all work?
Surely this isn't secure?
Can I improve this?

If I am inferring correctly what you are describing, it sounds like the "brains" of the system are installed outside with one screw access. That, of course, is an abysmal design. The only thing that should be outside accessible would be the wires to the call button and speaker - all other wiring should be inside-access only.
If you are otherwise happy with the system, you could probably move the components that should not be outside inside, leaving only the wiring needed for the outside components running to the outside box.
