2-Wire Video Intercom 8-Button Outdoor Station: Connection & Settings via 2-Wire PoE

Modern apartment buildings and multi-family residential projects require entrance systems that combine video communication, access control, and simple installation.

A traditional IP intercom installation normally requires network cabling between the outdoor station and other system devices. However, a 2-wire video intercom system can simplify installation by using two wires for communication and power, making it particularly attractive for renovation projects and buildings where existing wiring needs to be reused.

La 8-button outdoor station is designed for multi-resident applications. Each physical button can be assigned to a different apartment or indoor monitor, allowing visitors to call the appropriate resident directly.

When combined with 2-wire PoE technology, the system can provide a practical connection method for apartment video intercom projects.

This guide explains the basic connection concept, outdoor station settings, button configuration, and important installation considerations.

What Is a 2-Wire Video Intercom System?

A 2-wire video intercom system is an entrance communication system that uses a two-wire connection between system devices.

Depending on the product architecture, the two-wire connection can carry communication signals and power, reducing the amount of cabling required.

This approach is especially useful when installing an intercom system in:

• Existing apartment buildings
• Residential renovation projects
• Villas
• Small apartment complexes
• Multi-family housing
• Buildings with limited cable infrastructure

2-wire IP technologies are available that transmit both network data and power over existing two-wire cabling. For example, commercial 2-wire Ethernet/PoE solutions are designed specifically to extend IP connectivity over existing two-wire infrastructure.

What Is an 8-Button Outdoor Station?

Un 8-button outdoor station is an entrance calling panel with eight independent calling buttons.

It is designed for situations where multiple residents need to be contacted from one building entrance.

A typical configuration may look like:

Bouton	Assigned Resident
Button 1	Apartment 101
Button 2	Apartment 102
Button 3	Apartment 103
Button 4	Apartment 104
Button 5	Apartment 105
Button 6	Apartment 106
Button 7	Apartment 107
Button 8	Apartment 108

The exact button-to-room assignment depends on the FARHD system configuration.

This makes an 8-button outdoor station particularly suitable for small apartment buildings and multi-family residential projects.

How Does a 2-Wire PoE Video Intercom Connection Work?

The basic concept is straightforward:

        PoE Network / Power
                │
                ↓
       2-Wire PoE Equipment
                │
                │
          2-Wire Cable
                │
                ↓
      8-Button Outdoor Station
                │
        ┌───────┼───────┐
        ↓       ↓       ↓
      Room 1  Room 2  Room 3
        │       │       │
        └──── Indoor Monitors

The exact topology and power arrangement must follow the FARHD product wiring diagram and the specified 2-wire PoE equipment.

Commercial 2-wire PoE systems commonly use a transmitter/leader side connected to Ethernet and power, with a remote receiver/follower converting the two-wire connection back to Ethernet and power for an IP device. Polarity requirements depend on the specific converter design.

---

Why Use 2-Wire PoE for Video Intercom?

1. Simplified Wiring

One of the biggest advantages is reduced cabling.

Instead of installing separate cables for different functions, a compatible 2-wire PoE architecture can transmit network communication and power over the same two-wire path.

This can simplify installation.

---

2. Useful for Existing Buildings

Renovation projects often have existing two-wire cabling.

Replacing all existing wiring with new Ethernet cable can increase:

• Labor costs
• Construction time
• Complexité d’installation

A compatible 2-wire IP/PoE solution can make it possible to upgrade existing infrastructure without completely redesigning the cable route.

---

3. Reduced Installation Complexity

A simpler cable architecture can make deployment easier for installers.

This is particularly useful in:

• Apartment renovations
• Older residential buildings
• Small multi-family projects

---

8-Button Outdoor Station Connection Process

Before installation, confirm the exact FARHD model, terminal definitions, compatible power equipment, cable specifications, and wiring diagram.

The following describes the general installation logic rather than replacing the product-specific manual.

---

Step 1: Prepare the Outdoor Station

Install the 8-button outdoor station at the main building entrance.

Consider:

• Visitor visibility
• Button accessibility
• Camera viewing angle
• Weather exposure
• Network/cable routing
• Door-lock wiring

The installation height should allow visitors to comfortably operate the call buttons and communicate with residents.

---

Step 2: Connect the 2-Wire PoE Line

Connect the two-wire cable between the compatible 2-wire PoE interface and the outdoor station according to the FARHD wiring diagram.

Important : Do not assume that every 2-wire PoE system uses the same terminal definition.

Some commercial 2-wire PoE converters specifically require correct polarity between the two conductors, while other systems use different architectures.

Therefore, installers should always follow the terminal markings of the actual FARHD product.

---

Step 3: Connect the Network Side

The 2-wire PoE equipment is connected to the IP network according to the system architecture.

A typical configuration is:

Router / Network Switch
          │
          │ Ethernet
          ↓
   2-Wire PoE Interface
          │
          │ 2-Wire
          ↓
  Outdoor Station / Remote IP Device

If the system uses a PoE switch or injector, verify that the power specification is compatible with the 2-wire PoE equipment.

Not all 2-wire converters should be connected directly to a PoE port. Some systems specifically require a non-PoE network port or a designated power arrangement.

---

Step 4: Connect Indoor Monitors

Each outdoor calling button needs to correspond to the appropriate indoor monitor or apartment.

For example:

Outdoor Button 1 → Indoor Monitor 101

Outdoor Button 2 → Indoor Monitor 102

Outdoor Button 3 → Indoor Monitor 103

Outdoor Button 4 → Indoor Monitor 104

Outdoor Button 5 → Indoor Monitor 105

Outdoor Button 6 → Indoor Monitor 106

Outdoor Button 7 → Indoor Monitor 107

Outdoor Button 8 → Indoor Monitor 108

The actual room-number assignment should be configured according to the FARHD system’s addressing method.

---

Step 5: Connect the Electric Lock

The outdoor station can be integrated with an appropriate electric door lock or access-control device when supported by the specific model.

The basic access process is:

Visitor Calls Resident
        ↓
Resident Views Visitor
        ↓
Two-Way Communication
        ↓
Resident Confirms Identity
        ↓
Door Unlock

This combines visitor verification with controlled building access.

---

How to Configure the 8 Calling Buttons

After the physical connection is complete, the next step is configuring the outdoor station.

The objective is simple:

Each button should call the correct indoor monitor.

For example:

Button 1

Assigned to Apartment 101.

Button 2

Assigned to Apartment 102.

Button 3

Assigned to Apartment 103.

Continue the same logic through Button 8.

The exact programming interface, room-number format, and addressing procedure depend on the FARHD model.

---

Room Number and Device Address Settings

For apartment intercom projects, correct addressing is essential.

Each indoor monitor should have a unique room or device address.

A simplified example:

Outdoor Station
       │
       ├── Button 1 → 101
       ├── Button 2 → 102
       ├── Button 3 → 103
       ├── Button 4 → 104
       ├── Button 5 → 105
       ├── Button 6 → 106
       ├── Button 7 → 107
       └── Button 8 → 108

This prevents a visitor from accidentally calling the wrong apartment.

For larger apartment projects, the addressing strategy should be planned before installation.

---

How to Test the 8-Button Outdoor Station

After connection and configuration, test every button individually.

Test 1: Button Calling

Press Button 1.

Confirm that the correct indoor monitor receives the call.
