Apartment and multi-tenant intercom systems: Complete guide

Why apartment building intercom systems are important

Residents in a multi-tenant apartment building receive different kinds of visitors they need to grant access to. Visitors may be friends or family, couriers delivering packages or food, hired contractors or tradespeople carrying out maintenance work.

When visitors arrive at the building entrance, they need a way to contact the person they’ve come to see. In a small apartment complex, guests could go to a front desk or concierge, but in a large complex with hundreds of units, front desk operations can be difficult to manage. 

Below are a few reasons why operating an apartment building intercom system is important:

• Directly connects tenants and guests: an apartment door buzzer system opens a direct line of communication between tenants and guests, enabling residents to grant entry to their own visitors and reducing the risk of accidental unauthorized intrusions.
• Provides quick identity verification: a multi-unit video intercom system allows each resident to check the identity of a visitor before they enter the building, enabling tenants to verify visitor identities both verbally and by reviewing live video footage.
• Offers remote-controlled access: apartment intercom systems with door release features enable tenants to unlock doors for guests from inside their own units. Some systems use mobile credentials and app-based controls so tenants can review requests from remote locations. 
• Reduces the workload of employees: managers, concierges and security staff juggle numerous daily responsibilities, and excessive time spent on access requests can divert attention from complex challenges, increasing the risk of accidental security breaches.
• Adds an extra layer of security: operating an apartment intercom system provides an extra opportunity for suspicious activities to be identified and addressed, with both front desk staff and individual tenants able to investigate odd requests and raise concerns.

For owners of apartment complexes, an apartment intercom system installation can strengthen building security, add value to the property and increase tenant satisfaction while reducing the workload of front desk and security staff.

Benefits of multi-tenant intercom systems 

Intercom systems for multi-unit buildings provide important benefits for residents, visitors, security teams and property managers, including: 

• Stronger security: apartment building intercom systems restrict access only to authorized persons for stronger security. Multi-apartment video intercom systems help security staff review access events and spot suspicious activities, with cloud-based intercom systems for apartment buildings enabling remote analyses round the clock.
• Enhanced visitor management: multi-unit intercom systems lessen staff workload and reduce the risk of bottlenecks by enabling residents to handle access requests themselves. This streamlines visitor management and improves the tenant experience.
• Improved visitor experience: apartment door intercom systems reduce wait times for visitors, allowing for quick access and fewer loitering issues. With an apartment video intercom system, visitors can establish their identities in a matter of seconds.
• Streamlined delivery management: online shopping and food deliveries can be contained in a central drop-off point, with a multi-unit video intercom system used to confirm deliveries with tenants. Temporary credentials can be issued to couriers if an app-based system is in use, allowing for fast and secure delivery management.
• Efficient parking control: multi-unit intercom systems positioned at vehicular entry points can be used to support efficient parking management, with incoming persons required to confirm their identities before being directed to designated parking spaces.
• Reduced support burden: multi-apartment video intercom systems help desk staff to reduce the time spent handling high volumes of visitors and deliveries. When a guest requests access, tenants or desk staff can assess the entry request from a secure smart device without being physically on-site. 
• Increased property value: apartment complexes equipped with intercom and lock release systems, particularly keyless access intercoms, are highly appealing to tenants due to their convenience, ultimately contributing to increased property values over time.

How do apartment intercom systems work?

Apartment intercom systems work by opening a direct line of communication between guests and authorized persons inside apartment complexes. When guests arrive, they’ll find a panel affixed to the door or gate, in the case of a gated community video intercom system, with buttons for each apartment, a microphone, speaker and in some cases, video display screen.

When a guest presses a door buzzer for apartments, a signal is sent to a receiver in the unit they’re requesting access from, or a smart device if a mobile-ready apartment door buzzer system is in use. The guest can then verify their identity verbally or visually, depending on the type of apartment intercom system installed, allowing the tenant to approve or deny access. 

Multi-tenant access control intercoms will record logs of access events for security purposes, enabling security teams to investigate suspicious activities. When connected to a property management system, entry logs can also be used to analyze occupancy, user behavior and other relevant datasets to help improve operations.

Types of intercom systems for apartment and condo buildings

There are three main types of intercom systems for multi-unit apartments:

• Apartment intercom buzzer 
• Apartment intercom cellphone system
• Video apartment intercom system 

Each of the solutions can be configured as an apartment intercom system with door release to enable remote door unlocking.

Components of an apartment intercom entry system

A multi-unit intercom system has the following basic components:

• Base stations at building entrances: base stations house apartment intercom system hardware, including buzzers, tenant directories, microphones, speakers and cameras. They’re usually installed at main entrances and vehicular access points, and constructed with weather- and tamper-resistant materials to help mitigate physical damage.
• Sub-stations in individual units or apps: sub-stations are user-facing control panels that tenants use to manage entry requests. They can be stationary panels installed inside units or digital platforms in the case of mobile or wireless apartment intercom systems with door release. When an access request is made at the base station, the relevant tenant’s sub-station will be contacted and its controls used to grant or deny access. 
• Directories of individual tenants: base stations for multi-family intercom systems store directories of all sub-stations in the complex, either on an on-site server or in the cloud. Visitors can search the directory manually and contact the relevant tenants using buttons on the main intercom panel or through voice controls in some apartment and condo video intercom systems.
• Communication network: base and sub-stations in multi-unit intercom systems are linked via direct cabling, Local Area Networks (LAN), Wide Area Networks (WAN) or wireless networks to transmit access requests between guests and tenants. Networks can be cost-effective, as they typically require fewer cables. Still, stable signal strength and speed must be maintained to avoid connection drops during periods of high user activity and traffic.
• Electronic door locks: apartment intercom systems with door release features enable tenants to unlock entrance doors from inside their apartments. A signal sent from a relevant substation triggers a relay, which releases a linked electronic lock. Commercial electronic door locks come in two types: electronic strike locks, which use motors to release the lock and magnetic locks, which rely on electromagnets for operation.
• Power supply for base stations and door locks: all major components of a multi-apartment video intercom system must be continuously powered to ensure tenant safety. Each component can be connected to dedicated power cables, or a PoE security system can be used to transmit both power and data through a single cable. Additionally, a backup generator should be installed to maintain operation during power outages. 
• System management: system management infrastructure aids security staff in managing, maintaining and updating multi-unit intercom systems. The infrastructure can be based on-site or in the cloud. On-site systems require frequent maintenance by on-site teams and can be hard to scale, while cloud-based systems can be updated and accessed over the internet, allowing for streamlined management.

Considerations for apartment intercom and buzzer systems

The effectiveness and reliability of an apartment intercom and buzzer system depend on the specific needs of each apartment complex. While key components such as base stations, sub-stations and electronic door locks are common across all systems, their configuration will vary based on user requirements.

When developing a new or upgrading an existing apartment intercom system, property owners, managers and security personnel must consider the following key factors:

1. Ease of use

To ensure apartment intercom systems are user-friendly and minimize tenant frustration, it’s essential to design intuitive installations. Apartment buzzer panels should be easy to navigate, networks must handle daily traffic efficiently and tenant directories should be well-organized and regularly maintained for visitor convenience.

Implementing an app-based or wireless apartment intercom system with door-release functionality enhances usability by allowing tenants to manage access requests remotely via smartphones. Additionally, opting for a cloud-based management system simplifies operations for security and front-desk staff by providing an online platform for streamlined oversight.

2. System connectivity

The key components of intercom systems for apartment buildings can be connected in a number of ways, each of which can be beneficial in specific environments. For example, a wired residential apartment intercom will be less likely to suffer connection loss and latency issues. Still, it can be time-consuming to install if the existing infrastructure is outdated or incompatible.

Wireless apartment intercom systems can be easier to install and scale, with new intercom panels requiring only a physical connection to a power source. However, a stable and consistent Wi-Fi connection must be present to avoid unexpected downtime and signal loss. 

3. Hardware design 

Aesthetics may not seem like a top priority. Still, as some of the major benefits of operating an apartment building intercom system are improved tenant satisfaction and increased property value, the hardware design must match the aesthetics of an apartment complex.

Multi-unit intercom system door panels should sit flush with the surfaces they’re installed in, and take on simple designs that are unlikely to look outdated soon. Installing a multi-unit video intercom system can help to improve aesthetic appeal by offering a clear visual representation of the system’s functionality and user-friendly design, attracting prospective tenants.

4. Device placement

The placement of apartment intercom buzzers significantly influences the type of installation best suited for the property. For instance, if numerous substations are needed, property owners must evaluate the practicality of connecting these devices to base stations and power supplies, considering the existing infrastructure.

Assess the number of access points required, including entrances to individual units, on-site facilities, parking lots and access roads, along with the costs and time involved in connecting and configuring the entire system. In some cases, implementing multiple intercom systems linked through a centralized cloud management platform may be a more efficient solution.

5. Communication types

Intercom systems for condominiums, gated communities and apartment complexes are often evaluated based on their communication capabilities. While basic one-way audio communication is a functional starting point, incorporating additional communication features can significantly enhance both security and convenience.

Apartment video intercom systems provide an added layer of security by allowing tenants to visually verify visitor identities. Systems with smartphone functionality further improve convenience by enabling users to communicate and manage access remotely. The broader the range of communication options, the more appealing the system becomes to prospective tenants.

6. Upfront and ongoing costs

While advanced features like video displays, remote door release and app-based controls are highly desirable, affordability remains the most critical factor in selecting an apartment intercom system. Property owners must weigh the costs of infrastructure installation, including cables, hardware and power supplies, alongside ongoing management and maintenance expenses.

Upfront costs can often be minimized by ordering components in bulk or choosing Wi-Fi intercom systems that require less cabling. However, wireless or cloud-based systems come with additional considerations, such as subscription fees and service provider updates, which can add to long-term expenses.

7. Integration capabilities

To maximize the benefits of an apartment door intercom installation, consider potential integration opportunities with broader building management and security systems. Since not all apartment door buzzer systems include access control or door release features by default, it’s crucial to ensure proposed systems support integration with other security technologies.

Choosing an intercom system with an open API allows teams to integrate with additional systems, enabling intercom signals to trigger devices like apartment video security cameras, access control systems and alarms. Even if immediate integration isn’t required, having the flexibility to enhance the system in the future can provide significant value.
