A smart, secure, and remarkably simple video intercom solution for modern villas and homes.
When it comes to villa security, reliability and simplicity matter. The FARHD 2-Wire Villa Kit delivers both – combining a 7-inch indoor monitor with Tuya WiFi connectivity and an outdoor call panel with card unlock functionality. Whether you’re building a new home or upgrading an existing intercom system, this kit offers a smart, secure, and surprisingly simple solution.
Let’s walk through what makes this system tick – from its core functions to step-by-step connection guidance.
Why 2-Wire? The Simplicity Advantage
Traditional intercom systems often require complex multi-core cabling, making installation expensive and disruptive – especially in existing homes. The 2-wire system changes that entirely.
Using just two standard wires (non-polarity, so there’s no worry about connecting them backwards), the system transmits power, video, audio, and control signals simultaneously. This means:
- Reuse existing wiring – often works with old doorbell or telephone wires already in your walls
- No polarity concerns – connect either way, no risk of reverse polarity damage
- Fast installation – any electrician (or confident DIYer) can set it up quickly
- Lower cost – less labour, less material, less disruption
- Transmission up to 100 metres – plenty of distance for most villa layouts

Room-to-Room Calling – If you have multiple indoor monitors installed, you can use them for internal communication between rooms.
Outdoor Call Panel Functions
One-Button Calling – Visitors press the call button, and the system rings both the indoor monitor and (if configured) the Tuya app on your smartphone.

Connection Guide – Step by Step
The system uses a simple 2-wire (non-polarity) connection. Here’s how to set it up.
Step 1: Plan Your Installation
- Choose a location for the outdoor call panel near your entrance (eye level, about 1.5 metres high)
- Choose a location for the indoor monitor inside your home – somewhere convenient where you’ll hear the ringtone
- Plan the cable route between them (up to 100 metres / 300 feet)
Step 2: Connect the Wires
- Use the provided 2-core wires (or your own ≥0.5mm two-core cable)
- Connect one end to the outdoor panel’s 2-wire terminals
- Connect the other end to the indoor monitor’s 2-wire input terminals
- No polarity – you can connect either wire to either terminal
Step 3: Power the System
- Connect the power adapter to the indoor monitor
- The indoor monitor supplies power to the outdoor panel through the same 2-wire connection – no separate power supply needed at the door
Step 4: Physical Mounting
- Mount the outdoor panel securely near your entrance
- Mount the indoor monitor on the wall using the included bracket
Step 5: Test the System
- Press the call button on the outdoor panel
- The indoor monitor should ring instantly and display the video feed
- Test two-way audio and the unlock function
