Essentially a door buzzer entry system is composed of a microphone and keypad unit located at the main entrance. The unit is connected to a telephone receiver located inside the building. This may be on the desk of an employee or mounted conveniently on a wall. The system is activated when a visitor presses the call button on the keypad enabling a two-way conversation to take place between the visitor and a representative of the business.

If the visitor is permitted entry, the door is unlocked remotely by pressing a button on the representative’s telephone handset. The visitor hears an audible ‘buzzer’ noise indicating that the door is unlocked and that they can enter the building.
