What is a door entry intercom system?

A door entry intercom system is an electronic device that controls access at a door by allowing visitors to request entry from tenants. Moreover, door access intercoms allow you to keep doors locked for security while providing a way for tenants and authorized visitors to enter easily.

To do this, visitors call a tenant using the intercom system, and then tenants remotely unlock the door using the same system.

Door entry intercom systems consist of hardware installed at the door. In addition to the hardware at the entrance, these systems also include devices that residents use to grant remote access. These hardware components are called intercom door stations.


What is an intercom door station?

An intercom door station is one component of an intercom entry system. However, there are two kinds of intercom door stations: base stations and substations.

Base stations are installed at the front door to control access to the property. Visitors use intercom base stations to request property access by calling a resident.

In contrast, substations are installed within the building, often within each unit. Tenants use these intercom door stations to answer calls from visitors and grant them property access remotely. An intercom substation could be one of many devices, from wall-mounted screens to tenants’ own smartphones.

How does a door entry intercom system work?

Door entry intercom systems work by establishing a connection between base stations and substations, which enables visitors to communicate with tenants and request building access.

First, when a visitor arrives at the door, they contact a specific tenant (or a staff member, if the building provides that option). Then, when a visitor calls a tenant, the door entry system’s base station establishes a connection with that tenant’s substation.

After a tenant answers the call, they can choose to open the door for their visitor. Further door entry intercom systems require a door release mechanism, which unlocks the door upon receiving a signal from the intercom. As a result, you’ll need to make sure your door has an electronic or magnetic lock to enable remote access.


What to consider when buying a door entry intercom system

When shopping for a door entry intercom, consider a few factors before purchasing one.

These are the key considerations before buying a door entry intercom:


Type of building

First, consider the type of building where you’ll install your entry system. For a multifamily property, you’ll want an apartment intercom system. But for an office building, you’ll need a commercial door entry system.

Some intercom entry systems are designed specifically for one type of building. However, others are multipurpose and can be installed at virtually any kind of property.
So, when researching intercoms, be sure to double-check that the system works in the kind of building you own or manage.


Video capabilities

Outdated buzzer systems only allow visitors and tenants to talk to each other — they can’t see each other. Fortunately, some modern intercom entry systems have video-calling capabilities.

A video door entry system has a camera built into the base station at the entrance. When a visitor uses the system to contact a resident, the camera enables a video call so residents can see who’s at the door. And if the system’s substations include a camera, visitors can see tenants during the video call.

Having a video door entry system enhances security by empowering residents to visually confirm who’s requesting access before letting them in. Whether you’re replacing an old intercom or purchasing one for a new development, it’s in your best interest to buy a video intercom system.

Door entry intercom systems can be wired or wireless. For best results, choose a wireless front door intercom.

A wireless door entry intercom system enables communication between visitors and tenants without any wired hardware. Since the system operates over a wireless connection, you don’t have to spend time or money ripping up floors or tearing down walls to lay wiring. In contrast, a wired door intercom is difficult to install, and the cost of wiring plus hardware adds up quickly.

The benefits of choosing a wireless door intercom include:

  • Simpler and cheaper installation
  • Easier maintenance
  • No need to purchase expensive wiring
  • It’s easier to replace the system if you want to upgrade in the future


Hardware options

When purchasing a door entry intercom, pick a system with durable yet easy-to-use hardware. Remember, you’ll need two hardware components: the base station at the entrance and the substations within the building.

For best results, choose a system with base station hardware that:

  • Has a touchscreen
  • Is IP65 rated (especially if you’ll be installing an outdoor door entry intercom system)
  • Adds curb appeal to your building


A modern touchscreen intercom is the way to go because it’s intuitive to use and looks sleek at any building.

As for substation hardware, it’s actually better to eliminate the in-unit hardware altogether. Instead, choose a door entry intercom that operates with tenants’ smartphones. That way, you’ll save time and money installing hardware throughout the building. Plus, tenants will enjoy the convenience of using a device they already have in their pockets.



There’s not much to an old apartment buzzer system — just a few buttons to talk to a visitor and open the door. But modern door entry intercom systems offer a wide range of additional features that improve the access experience.

To enjoy all the best features, choose an IP door entry system. IP entry systems operate over the internet, which enables tons of great convenience-focused features. Not only will those features simplify access, but they’ll help improve the resident experience at your building.

Look for these desirable features when choosing an intercom system:

  • Virtual keys or digital access codes for guests
  • Delivery PIN codes and passes for couriers to easily gain access
  • Keyless entry methods (the best keyless entry solution is mobile app-based access)
  • Remote system management, ideally from a cloud-based dashboard
  • Integrations with other proptech


Door entry intercom system FAQs

Here are some common questions about door entry intercom systems:


What is the difference between a doorbell and an intercom?

The main difference between a doorbell and an intercom lies in their capabilities. A doorbell relies solely on an audio signal or chime to alert you when a visitor is at your door. In contrast, an intercom not only alerts you of a guest’s presence but empowers you to actually communicate with your visitor prior to letting them in.


What is an intercom entry system?

An intercom entry system is a two-way communication system that controls access to your building by providing tenants and visitors a way to communicate with each other before granting guest access.


How do you open a door with an intercom?

To open a door with an intercom, a door release mechanism is used to automatically grant someone access once they’ve been authorized to enter your building by your intercom system.
