The whole system works in a very smooth manner, the panels are embedded on the wall that is connected to the locking system that holds the door together. The panel can be unlocked using any of the code, special cards or finger prints.

The door panel used might be designed in order to work on specific codes. A code has been given to the door entry system and it just authorizes entries once the code that you enter matches to that of the internal security system.
