Types of Door Buzzer Systems & How They Work

There are several types of door buzzer systems to choose from, depending on your building’s size, usage, and security needs. The most basic systems allow visitors to press a button and speak to a tenant, who then buzzes them in remotely. These can be wired or wireless, and they’re common in small residential buildings.

Keypad systems add a layer of convenience, allowing authorized users to enter a code to gain access without needing a key or call. Many of these systems also log entry times, which is helpful in shared commercial spaces or multi-tenant buildings.

Smart door buzzer systems go a step further. These systems connect to mobile apps, enabling users to see, talk to, and buzz in visitors from anywhere. This is ideal for remote management, deliveries, or service providers when you're offsite. They can also integrate with other security components like intercoms, access control panels, and surveillance cameras.

Choosing the right system depends on factors like the number of users, the level of control you want, and your budget. At Queens Security Systems, we help you find the best fit for your property—whether you need simple, secure access or full integration with a smart security system.
