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?
