Top Door Buzzer Systems for Business: Enhance Security and Efficiency

More than 189,000 commercial and office buildings in the U.S. have been burglarized over the past five years, according to FBI data. Not surprisingly, managing access is a top priority for many companies, especially those that handle money and sensitive information.

Traditional access management systems—including mechanical locks, physical keys and badge systems—are inconvenient and can leave businesses vulnerable to intruders. Modern door buzzer systems offer a more secure, efficient and user-friendly solution across various commercial settings, including multifamily communities.

What is a door buzzer system?

Door buzzer systems are devices that control access to buildings, allowing visitors in and out without anyone needing to manually open the door. They improve security by keeping unauthorized visitors from entering, boost convenience by allowing occupants to manage visitors and deliveries from inside, and often keep records to help companies track visitors.

Here’s how a door buzzer system works:

1. 1.Visitor interaction: The visitor pushes a button on the exterior of the building, which sends an electric signal to the system inside.
2. 2.Occupant notification: The system triggers a buzz, chime, or recording to notify the occupant that a visitor has arrived. Some systems allow two-way audio or video communication between the visitor and occupant.
3. 3.Access control: The occupant presses a button that sends an electric signal to allow entry.

Key components of a door buzzer system

Each element of a door buzzer system plays a crucial role in boosting security and convenience.

Exterior entry hardware

• ​Buzzer button: Triggers a notification inside the building, allowing an occupant to remotely unlock the door
• ​Electric lock: Secures the door by engaging with the door frame
• ​Electric door strike: Connects with the lock and allows the door to open remotely without anyone physically unlocking it

Interior hardware

• ​Power supply: Operates the components by providing electrical power to the system
• ​Control panel: Provides a hub to communicate with visitors and allow entry
• ​Wiring: Connects the components, transmitting signals between the power supply, control panel, and electric door strike or lock (only for wired systems)

Optional components

• ​Access readers: Allow entry into the building with a PIN, keycard or fob
• ​Intercom panels: Allow two-way communication between visitors and occupants
• ​Cameras: Provide visual identification of the visitor
• ​Motion sensors: Detect visitors approaching the building
• ​Mobile apps: Enable remote control and monitoring of the door buzzer system

Businesses that benefit from door buzzer systems

These systems are ideal for businesses that need to control access while allowing some visitors to enter. Multifamily communities, such as apartment buildings, dormitories, and assisted living facilities, are prime examples. Three-quarters (75%) of renters in the 2024 National Multifamily Housing Council and Grace Hill Renter Preferences Survey said they wanted controlled property access. On-site teams also benefit from using door buzzers to let in delivery drivers, vendors and service providers.

Other businesses that benefit from door buzzer systems include office buildings, schools, manufacturing facilities, medical practices and more. In these situations, the buzzer system typically connects to a central point, such as a front desk, where one person manages entry.

Types of door buzzer systems

Choosing a system can be overwhelming, with many available options. Here are some of the most common system types.

Wired door buzzer systems

These systems rely on physical cables to connect the buzzer, control panel, lock and power supply. Wires link the door buzzer to a central location, which connects to a panel in each unit. The most basic wired door buzzers include a simple button and chime. Two-wire systems send and receive audio. Three-wire and four-wire systems add extra features, such as video communication. Wired systems offer exceptional reliability and sound quality, but require professional installation and can be more costly to install.

Pros:

• ​High level of security and reliability
• ​Excellent audio quality
• ​Consistent supply of power
• ​No wireless interference

Cons:

• ​Require professional installation
• ​Need regular maintenance
• ​Limit easy relocation or upgrades

Wireless door buzzer systems

These battery-powered systems communicate using radio signals, a cellphone network, WiFi or Bluetooth. They usually include a wireless entry panel on the outside of the building for visitors and receivers on the inside for occupants. Wireless systems are simple to install and relocate, but require good wireless connectivity.

Pros:

• ​Easy to use
• ​Enable easy relocation and upgrades
• ​Require little maintenance
• ​Simple installation process

Cons:

• ​May be prone to wireless interference
• ​Need regular battery changes
• ​Require a reliable wireless connection

Intercom door buzzer systems

These systems allow two-way audio communication between visitors and occupants. They typically include an intercom panel at the entrance and a panel in each unit, each featuring a microphone and speaker. These systems improve security compared to simple buzzer systems and may be more affordable than video door buzzer systems.

Pros:

• ​Allow the occupant to hear the voices of visitors for identity verification
• ​Provide convenience for the occupant

Cons:

• ​Lack video or mobile integration
• ​May require regular maintenance
• ​Offer a lower level of verification than video systems

Video door buzzer systems

These systems integrate video capabilities, allowing occupants to see and talk to visitors. They typically include a speaker, microphone, and video camera at the base station at the building’s entrance and the substations inside the building. Some video intercom systems allow two-way video, while others only allow the occupant to see the visitor.

Market analysts expect the demand for video intercom systems to grow at a compound annual growth rate of more than 13% between 2024 and 2032. Video systems offer the highest level of security for building occupants, but are more expensive to install and maintain than other options.

Pros:

• ​Allow the occupant to see and hear the voices of visitors for verification
• ​Offer a high level of security
• ​Provide convenience for the occupant

Cons:

• ​Higher installation and maintenance costs
• ​Require robust security features to protect privacy and safeguard data

Key features to look for in a door buzzer system

When comparing options, consider these factors:

Ease of installation and setup

Wired systems usually require professional installation. Wireless systems are more DIY-friendly.

Compatibility with existing infrastructure

Ensure your system works with your door type, entryway configuration, and electrical wiring. Assess your building layout and number of units to ensure effective wiring or wireless coverage.

Power source options

Wired systems provide constant power and a reliable connection, but require electrical wiring and a power source. Battery-operated systems are easier to install, but require battery replacement or recharging.

Communication features

Decide if a simple door buzzer is adequate, or if audio and video communication would benefit your occupants. Video offers the highest level of security, but can be more complicated and expensive to install.

Security features

Look for features such as:

• ​Access control integration: Works with your access control system, including card readers or keypads.
• ​Security system integration: Coordinates with your security system for a unified response.
• ​Data encryption: Protects collected data.

User interface and controls

Choose a system with a user-friendly and intuitive interface. If your base station control panel includes a directory of occupants, ensure it’s easy to navigate and read.

Durability and build quality

Look for a sturdy system made from durable materials that can handle the elements and frequent use.

Integration with other systems

Your system should work seamlessly with your security, access control, and smart home systems. Ideally, occupants should be able to access all these systems from a single interface.

Cost and budget

Balance the features you want with cost, factoring in long-term expenses such as repairs or replacements.
