How Do Commercial Door Buzzer Systems Works?

Office building with door buzzer intercom access system.

A commercial door buzzer system comprises a microphone and keypad unit at the main entrance. The unit is connected to a telephone receiver located inside the building. It may be on an employee’s desk or mounted conveniently on a wall of a building or property.

The door buzzer system is activated when a visitor presses the call button on the keypad, enabling a two-way conversation between the visitor and a business representative.

If the visitor is permitted entry, the front 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 they can enter the building.

Generally, commercial door buzzer systems range between $850-$10,000. The wide cost estimate is because each commercial buzzer system varies depending on multiple factors.

As with most security equipment, many door buzzer systems are on the market to consider. Regarding the pricing of buzzer systems, the more comprehensive the buzzer system is, the higher the cost.

For example, buzzer systems that do not include a camera will generally be less expensive than those that integrate.

Among these are the layout of the space, placement of the hardware and equipment, and integration requirements of installing buzzer systems, which have relative effects on the cost of the unit. 

There is no doubt that a properly installed and well-maintained door buzzer entry system is an integral part of a building’s security infrastructure.
