Electronic access control systems replace the traditional lock and master key system. They provide commercial access security by allowing entry through different entry devices. The 3 basic types of devices are :
Along with the entry device, the other component of the electronic access control system is the control panel with a software that contains the database of people who are given permission to enter the building or facility. It likewise has the commands for each entry point. This makes it possible to control the time that each door opens and closes and dictate who is given permission to enter or exit.
As an additional security feature, an audit trail is created for each person who enters and exits the premises, as well as the exact time of entry/exit. This is particularly helpful when investigating incidents of theft or security breach.
