Step inside for an immersive walkthrough and explore: 4-Wire | 2-Wire | IP | Analog | Audio | Wireless
At FARHD, we don’t just sell intercoms – we provide complete system solutions for every type of residential and commercial project. Our showroom is a living demonstration of this commitment, featuring all six of our core intercom systems under one roof.
Whether you’re a property developer, system integrator, installer, or distributor, the question isn’t “does FARHD have a solution?” – it’s “which one fits your project best?”
Let’s take a closer look at each system, what makes it unique, and who it’s best suited for.
The Six Systems – A Quick Overview
1. 4-Wire Analog System
The classic workhorse.
The 4‑wire system is the backbone of traditional analog intercoms. Separate power and signal lines ensure stable, interference‑free communication over long distances (up to 100 metres). Supports up to 2 outdoor stations and 4 indoor monitors.
Best for:
- Villas and townhouses with multiple entrances
- Small to medium apartment buildings (up to 8 units)
- Retrofit projects where existing 4‑wire cabling can be reused
- Projects where reliability and simplicity are top priorities
Key advantage: Proven, stable technology – no network dependency.
2. 2-Wire System
The retrofit champion.
The 2‑wire system transmits power, video, audio, and control signals over a single pair of existing two‑core cables. Non‑polarity design means you can’t connect them backwards. Transmission distance up to 100 metres.
Best for:
- Villa upgrades using existing doorbell or telephone wires
- Old building retrofits – no rewiring, no wall damage
- Budget‑conscious residential projects
- Projects where running new cables is impractical
Key advantage: Reuses existing cabling – dramatic cost and time savings.
3. IP System
The smart home backbone.
Fully network‑based with TCP/IP, PoE support, Tuya/Smart Life app integration, and ONVIF camera compatibility. Supports up to 9,999 apartments, face recognition, and elevator control integration. HD video, remote access, and expandable architecture.
Best for:
- New builds and smart homes
- Large apartment complexes and high‑rise towers
- Gated communities and residential developments
- Projects requiring remote access and app integration
Key advantage: Future‑proof, scalable, and remotely accessible.
4. Analog System
Simple. Reliable. Always works.
A proven, mature technology for projects that prioritise stability and cost‑effectiveness. Works without network dependency – just reliable, always‑on communication. No IP addresses, no network configuration.
Best for:
- Budget‑conscious residential and commercial projects
- Buildings with existing analog infrastructure
- Projects where network infrastructure is limited or unreliable
- Simple, straightforward access control needs
Key advantage: Low cost, high reliability, zero network dependency.
5. Audio System
Voice‑only. Cost‑effective. Scalable.
A voice‑only intercom solution for projects where video is not required. Scalable up to 1,024 units with decoder system. Clear two‑way communication, IC card unlock support, IP65 outdoor station.
Best for:
- Large housing developments and public housing projects
- Dormitories and staff housing
- Budget‑conscious apartment buildings
- Projects where only voice communication is needed
Key advantage: Lowest cost per unit – ideal for large‑scale deployments.
6. Wireless System
No wires. No limits. Smart security.
Solar‑powered or battery‑operated, with 868/915MHz RF technology (not Wi‑Fi) for stable, interference‑free communication up to 100 metres. 7‑inch IPS touch screen indoor monitor, 1080P HD camera, Tuya app integration, motion detection, and local storage.
Best for:
- Villas and homes where running cables is impractical
- Rental properties – easy to install and remove
- Remote or rural properties – no reliance on external power sources
- Renovation projects – add smart security without rewiring
Key advantage: Zero cabling, solar power, easy DIY installation.
