A modern approach to apartment entry—where every unit has its own IP video doorbell, enabling direct, private, and efficient communication between visitors and residents. No shared panels, no confusing directories, no missed calls. This is the IP direct-call apartment system.

In traditional apartment buildings, a single outdoor panel serves the entire building. Visitors scroll through a directory, search for a name, or enter a room number—and hope they’ve got it right. When the system is busy, calls queue. When the panel fails, the whole building loses its intercom. And when a resident is not home, the visitor has no way to reach them directly.

The IP direct-call apartment system changes that. By connecting one IP video doorbell per apartment, each unit gains its own dedicated entry point. Visitors call the specific apartment directly. Residents answer on their indoor monitor or smartphone. And property managers gain a scalable, network-based system that is easy to manage and expand.

This guide explains how the system works, why it benefits residents and property managers, and how FARHD delivers it for residential projects worldwide.

What Is an IP Direct-Call Apartment System?

An IP direct-call apartment system is a network-based intercom solution where each apartment has its own IP video doorbell—typically an outdoor station or call panel installed at the apartment’s entrance or in a shared corridor. This doorbell is connected to the building’s IP network and is programmed to call only that apartment’s indoor monitor or mobile app.

Instead of a single communal panel serving dozens of units, each apartment has its own dedicated device. This creates a one-to-one relationship between the outdoor call point and the resident.

The system is built on IP technology (TCP/IP), meaning it uses standard Ethernet cabling (CAT5/6) with PoE support. It can integrate with indoor monitors, mobile apps (Tuya/Smart Life), access control systems, and building management platforms.

Why One IP Video Doorbell per Apartment?

The traditional shared-panel model has served buildings for decades, but it comes with limitations. A direct-call system addresses these limitations head-on.

Challenge with Shared Panels	How Direct-Call Solves It
Directory searching – Visitors scroll through long lists; names may be outdated.	Direct call – Visitor presses the button for the specific apartment. No directory, no searching.
Call queuing – Multiple visitors may need to use the panel; calls can wait.	Dedicated device – Each apartment has its own doorbell. No queuing.
Single point of failure – If the shared panel fails, the whole building loses intercom.	Distributed system – A failure in one doorbell does not affect others.
Limited privacy – Calls may be visible or audible to others in the lobby.	Private communication – The call goes only to the intended apartment.
Resident not home – Visitor cannot reach the resident.	App forwarding – Calls can be forwarded to the resident’s smartphone.

For buildings with separate entrances per unit (e.g., garden-style apartments, townhouses, or low-rise blocks), direct-call systems are a natural fit. For high-rise buildings, they can be deployed in corridors or elevator lobbies, giving each apartment its own call point.

How It Works: System Architecture

The IP direct-call apartment system consists of several components, all connected over the building’s IP network.

1. IP Video Doorbell (Outdoor Station)

• Installed at the apartment entrance or in a shared corridor.
• Includes camera, microphone, speaker, and call button.
• Connects to the network via CAT5/6 cable (PoE).
• Programmed with the apartment’s unique address (e.g., room number).
• When pressed, it calls only the associated indoor monitor and mobile app.

2. Indoor Monitor

• Wall-mounted touchscreen inside the apartment.
• Receives video calls from the doorbell.
• Allows two-way audio communication.
• Features an unlock button for door release.
• Connects to the network via Ethernet or Wi-Fi.

3. Mobile App (Tuya / Smart Life)

• Allows residents to receive calls, view live video, and unlock the door from their smartphone.
• Supports family sharing (up to 20 users).
• Provides motion detection alerts and event history.

4. Network Infrastructure

• PoE switch or injectors to power the doorbells.
• Router or gateway for internet connectivity (for remote access).
• CAT5/6 cabling throughout the building.

5. Access Control Integration (Optional)

• Connects to electric locks (magnetic, strike, motor).
• Relay output on the doorbell or indoor monitor triggers the lock.
• Can integrate with RFID card readers, keypads, or face recognition.

6. Management Platform (Optional)

• Centralized software for property managers.
• Add or remove residents, assign doorbells, manage access permissions.
• Monitor device status and access logs.

Applications: Where Direct-Call Systems Excel

The IP direct-call apartment system is ideal for:

• Garden-style apartments – Each unit has its own entrance; a doorbell at each door.
• Townhouses and row houses – Direct call from the front door to the resident.
• Low-rise apartment blocks – Each unit has a doorbell in the shared corridor.
• High-rise buildings – Doorbells in elevator lobbies or corridors for each apartment.
• Comunidades fechadas – Individual doorbells at each villa or unit.
• Alojamento para estudantes – Each suite or room has its own call point.
• Serviced apartments – Guests can be reached directly.

For buildings with a single main entrance, a hybrid approach can be used: a shared panel for the main entrance plus direct-call doorbells for secondary entrances or individual units.
