If you are still relying on a traditional doorbell that only makes a sound – or an old intercom that is barely functional – you are missing out on the security, convenience, and peace of mind that a modern video door phone system can bring. But for many homeowners and property managers, the thought of upgrading seems daunting. Running new cables? Drilling through walls? Complex network setup? Not anymore.
With FARHD’s Smart 2-Wire Video Door Phone System, you can enjoy all the benefits of a cutting‑edge smart intercom – HD video, app remote control, motion detection, and more – without the headache of complicated wiring. Whether you are building a new villa, renovating a townhouse, or upgrading an apartment building, this system is designed to be simple to install, smart to use, and built to last.
Let’s dive into what makes this 2-wire system the ideal choice for modern living.
Why 2-Wire? Because Installation Should Be Simple
Most video intercom systems require 4 or more wires – or a full CAT5/6 network cable – to transmit power, video, audio, and signals. That means drilling, channelling, and patching walls. In an already finished home, that is often impractical or simply too expensive.
Our 2-wire technology changes the game. It uses a single pair of ordinary two‑core wires (≥0.5mm, up to 100 metres) to carry everything: power, video, audio, and control signals. And because it is non‑polarity, you can connect the wires either way – no risk of reverse polarity.
What this means for you:
- Reuse existing wiring – If your home already has two‑core cables (old doorbell, intercom, or telephone wires), you may not need to run any new cables at all.
- No wall damage – Perfect for retrofitting occupied buildings.
- Fast installation – Any electrician can complete the setup in under an hour.
- Lower cost – Less labour, less material, less disruption.
7″ IPS HD Touch Screen – See Clearly, Act Instantly
The indoor monitor is the heart of the system, and this one is a standout. The 7‑inch IPS touchscreen delivers vivid colours, wide viewing angles, and sharp details – so you see visitors clearly from anywhere in the room. The responsive touch interface makes answering calls, adjusting volume, and unlocking doors effortless.
- 1024×600 resolution – crisp, high‑quality image.
- IPS technology – accurate colours even when viewed from an angle.
- User‑friendly interface – intuitive icons, easy navigation.
Whether you are in the living room, kitchen, or bedroom, you will always know who is at your door.
Tuya / Smart Life APP Remote Control – Your Door, Anywhere
Pair the system with the Tuya or Smart Life app (optional, but highly recommended) and you unlock a world of remote convenience:
- Remote answer – Receive video calls from your door station on your smartphone, wherever you are.
- Vista en directo – Check the camera feed anytime, day or night.
- Remote unlock – Let in deliveries, guests, or service providers with a single tap – no need to rush home.
- Alertas de movimiento – Get instant notifications when someone approaches your door.
- Event recording – View history of calls and motion events directly in the app.
The app is free, easy to set up, and works on both iOS and Android.
Motion Detection & Video Recording – Never Miss a Moment
The outdoor station includes a human motion sensor. When someone approaches or lingers near your door, the system can:
- Sound a chime on the indoor monitor.
- Push a notification to your smartphone (via the Tuya app) with a snapshot.
- Automatically record a video clip to the microSD card.
Con Micro SD Card Storage (up to 128GB), all recordings are stored locally – no cloud subscription, no privacy concerns. Loop recording ensures you always have the latest footage.
Room-to-Room Communication – Talk Between Indoor Monitors
If your villa or apartment has multiple indoor monitors (e.g., living room, master bedroom, home office), you can use the room‑to‑room calling function.
- Call family members without shouting or using a phone.
- Ideal for large homes where family members are in different rooms.
- Simple – press the room‑to‑room button and select the monitor you want to reach.
Support Up to 4 Indoor Screens – Perfect for Large Homes
The system supports up to 4 indoor monitors – so you can place a monitor in the living room, another in the bedroom, one in the kitchen, and even one in the home office. Answer calls from wherever you are, or use them for room‑to‑room communication.
Flexible expansion – Add more monitors as your needs grow, without changing the outdoor station.
Connect IP CCTV Cameras (ONVIF) – Expand Your Security
The indoor monitor can connect to up to 20 ONVIF‑compatible IP cameras over WiFi (2.4G / 5G). Add cameras to monitor your garden, garage, driveway, or back entrance – and view all feeds on the same 7‑inch screen or through the Tuya app.
- No separate NVR needed – the indoor monitor acts as the viewing hub.
- Easy switching – tap to cycle through camera views.
- Motion events – IP cameras with motion detection can also trigger alerts.
This turns your video door phone system into the centre of a complete home security network.
WiFi 2.4G / 5G Support – Reliable Wireless Connection
The system supports dual‑band WiFi (2.4GHz and 5GHz). This means:
- 2.4GHz – longer range, good for outdoor stations and cameras.
- 5GHz – faster speed, ideal for high‑quality video streaming to the indoor monitor and app.
The Tuya app uses this connection for remote access, live viewing, and push notifications.
Easy 2-Wire Installation – No Complex Wiring
We keep saving the best for last. The 2‑wire installation is so simple that most homeowners can do it themselves with basic tools.
- Mount the outdoor station near your entrance (gate or front door).
- Connect the 2‑wire cable to the terminals (no polarity, so no wrong way).
- Connect the other end al monitor interior.
- Plug in the power adapter – the indoor monitor supplies power to the outdoor station over the same two wires.
- Power on and test – press the call button on the outdoor station. The indoor monitor rings instantly and displays the video feed.
That is it. No IP addresses, no network configuration, no app pairing (unless you want remote access). Any electrician – or a confident DIYer – can do it.
