You’d think a door buzzer system would be a simple thing.
But once you start looking, there’s a surprising number of options – and even more opinions. Wired, wireless, video, app-controlled… it adds up fast.
We’ll lay it out clearly: what the different systems do, how much they cost, what setup involves, and how to make the right call for your space.
Key Notes
Choose between audio-only, video, wireless, or smart systems based on security needs.
Wireless systems cost $350-$1,100 while wired systems range from $450-$1,900 installed.
DIY wireless setups work for homes, professional installation recommended for commercial properties.
Wired systems last 10-15 years versus 5-8 years for wireless options.
What Is a Door Buzzer System?
A door buzzer system is an access control system that allows you to grant or deny entry to visitors from a remote location.
When someone presses the buzzer at your building entrance, the system alerts the inside occupant – via a receiver, intercom, or smartphone – and the door can be unlocked remotely with the press of a button.
Door buzzer systems typically consist of:
An exterior call station (buzzer panel)
Interior receiver(s) with an unlock function
Electric door strike or maglock
Optional features: video cameras, keypads, RFID card readers, or app control
Why Use a Door Buzzer System?
Security: You control who enters your property.
Convenience: Let in deliveries, guests, or staff without walking to the door.
Monitoring: Many systems log access or provide video footage.
Compliance: Commercial properties often require controlled entry points.
Types of Door Buzzer Systems

1. Audio-Only Door Buzzer Systems
Basic intercoms that allow two-way voice communication
No video feed or visual verification
Common in older apartment buildings
2. Video Door Buzzer Entry Systems
Includes a built-in camera
Lets tenants verify identity visually before granting access
Often paired with cloud recording and mobile access
3. Wireless Door Buzzer Entry Systems

No major wiring required
Suitable for retrofits or locations with limited infrastructure
4. Wired Door Buzzer Systems
Hardwired connections between all components
More reliable but expensive and invasive to install
Better for new builds or long-term installations
5. Keypad or PIN-Based Buzz-In Systems
Grant access via shared codes or unique PINs
Often integrated with visitor scheduling or delivery workflows
6. RFID or Card-Based Buzzer Systems
Require employees or tenants to tap an ID card or fob
May be combined with intercom or camera for added control
7. Smart Door Buzzer Systems
App-controlled via smartphone
Includes video, notifications, and cloud-based logs
Can be integrated with Alexa, Google Assistant, or smart locks

Frequently Asked Questions
Can I use a door buzzer system for multiple entrances in one building?
Yes, many commercial and smart systems support multiple entry points. You can configure different access rules or user permissions per door and control everything from a central dashboard or mobile app.
Is there a difference between a door buzzer and an intercom system?
Yes. While often used together, they serve different functions. A door buzzer system controls access (granting or denying entry), while an intercom allows two-way communication. Many modern systems combine both into one unit.
Are buzzer systems weatherproof for outdoor use?
Most exterior call stations are designed with weather resistance in mind. Look for models with an IP65 or higher rating to ensure protection against rain, dust, and temperature fluctuations – especially for NYC winters.
Can I connect a door buzzer system to an existing phone line or VoIP setup?
Some wired intercom-style buzzer systems can integrate with landlines or office PBX systems. Newer models often use VoIP or cloud-based connections and may require a compatible network setup.
Conclusion
A door buzzer system is a practical way to manage access, improve safety, and keep things running smoothly, whether at home, in the office, or across a commercial property.
From basic audio intercoms to wireless video systems with smart integrations, there’s a setup for every need and budget.
The key is choosing the right type, understanding the installation options, and factoring in long-term reliability and security.
