If you are still relying on a traditional doorbell that only makes a sound โ or an old intercom that is barely functional โ 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 FARHDโs Smart 2-Wire Video Door Phone System, you can enjoy all the benefits of a cuttingโedge smart intercom โ HD video, app remote control, motion detection, and more โ 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.
Letโs 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 โ or a full CAT5/6 network cable โ 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 twoโcore wires (โฅ0.5mm, up to 100 metres) to carry everything: power, video, audio, and control signals. And because it is nonโpolarity, you can connect the wires either way โ no risk of reverse polarity.
What this means for you:
- Reuse existing wiringย โ If your home already has twoโcore cables (old doorbell, intercom, or telephone wires), you may not need to run any new cables at all.
- No wall damageย โ Perfect for retrofitting occupied buildings.
- Fast installationย โ Any electrician can complete the setup in under an hour.
- Lower costย โ Less labour, less material, less disruption.
7โณ IPS HD Touch Screen โ See Clearly, Act Instantly
The indoor monitor is the heart of the system, and this one is a standout. The 7โinch IPS touchscreen delivers vivid colours, wide viewing angles, and sharp details โ so you see visitors clearly from anywhere in the room. The responsive touch interface makes answering calls, adjusting volume, and unlocking doors effortless.
- 1024ร600 resolutionย โ crisp, highโquality image.
- IPS technologyย โ accurate colours even when viewed from an angle.
- Userโfriendly interfaceย โ 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 โ 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 answerย โ Receive video calls from your door station on your smartphone, wherever you are.
- Vista dal vivoย โ Check the camera feed anytime, day or night.
- Remote unlockย โ Let in deliveries, guests, or service providers with a single tap โ no need to rush home.
- Avvisi di movimentoย โ Get instant notifications when someone approaches your door.
- Event recordingย โ 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 โ 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 โ no cloud subscription, no privacy concerns. Loop recording ensures you always have the latest footage.
Room-to-Room Communication โ 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 roomโtoโroom calling function.
- Call family members without shouting or using a phone.
- Ideal for large homes where family members are in different rooms.
- Simple โ press the roomโtoโroom button and select the monitor you want to reach.
Support Up to 4 Indoor Screens โ Perfect for Large Homes
The system supports up to 4 indoor monitors โ 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 roomโtoโroom communication.
Flexible expansion โ Add more monitors as your needs grow, without changing the outdoor station.
Connect IP CCTV Cameras (ONVIF) โ Expand Your Security
The indoor monitor can connect to up to 20 ONVIFโcompatible IP cameras over WiFi (2.4G / 5G). Add cameras to monitor your garden, garage, driveway, or back entrance โ and view all feeds on the same 7โinch screen or through the Tuya app.
- No separate NVR neededย โ the indoor monitor acts as the viewing hub.
- Easy switchingย โ tap to cycle through camera views.
- Motion eventsย โ 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 โ Reliable Wireless Connection
The system supports dualโband WiFi (2.4GHz and 5GHz). This means:
- 2.4GHzย โ longer range, good for outdoor stations and cameras.
- 5GHzย โ faster speed, ideal for highโquality 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 โ No Complex Wiring
We keep saving the best for last. The 2โwire installation is so simple that most homeowners can do it themselves with basic tools.
- Mount the outdoor stationย near your entrance (gate or front door).
- Connect the 2โwire cableย to the terminals (no polarity, so no wrong way).
- Connect the other endย al monitor interno.
- Plug in the power adapterย โ the indoor monitor supplies power to the outdoor station over the same two wires.
- Power on and testย โ 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 โ or a confident DIYer โ can do it.
