When you combine the durability of an aluminum casing, the convenience of card unlock, the simplicity of 2-wire installation, and the clarity of a 7-inch indoor monitor, you get a video intercom system that excels in both performance and aesthetics. FARHD’s 2-Wire Video Door Phone with aluminum call panel is designed for villas, apartments, and commercial buildings that demand reliable security and modern style.

In the world of building security, the entrance is the first point of contact and the first line of defense. It needs to be robust, secure, and easy to use—for residents and visitors alike. The FARHD 2-Wire Video Door Phone with an aluminum casing call panel delivers exactly that: a premium outdoor station that withstands the elements, supports card-based access, and connects effortlessly to a 7-inch indoor monitor via a single pair of wires.

This guide explores every aspect of this system: its features, benefits, installation, and why it’s an ideal choice for your next project.

Why Aluminum Casing? Durability Meets Elegance

The outdoor call panel is constantly exposed to weather, potential vandalism, and daily wear. The choice of casing material is therefore critical. FARHD uses aluminum alloy for the outdoor call panel, offering significant advantages over plastic alternatives.

Key benefits of aluminum casing:

• Superior durability – Resists impact, scratches, and deformation.
• Corrosion resistance – Anodized aluminum withstands moisture, salt air, and temperature extremes.
• UV stability – Does not fade, crack, or become brittle under prolonged sun exposure.
• Premium appearance – A sleek, metallic finish that enhances the building’s facade.
• Heat dissipation – Aluminum helps manage internal temperatures, contributing to reliable operation in hot climates.

With an IP65 weatherproof rating, the aluminum call panel is dust-tight and protected against low-pressure water jets, ensuring reliable operation in rain, snow, and dust. Its operating temperature range of -40°C to +70°C makes it suitable for virtually any climate, from freezing northern winters to scorching desert summers.

Card Unlock: Convenient, Secure, and Keyless

The aluminum call panel includes a built-in RFID/IC card reader, enabling residents to unlock the door with a simple tap of a card or fob. This keyless entry method offers multiple advantages.

Why card unlock matters:

• Wygoda – No fumbling for keys, especially when hands are full.
• Bezpieczeństwo – Each card has a unique code; lost cards can be instantly revoked.
• Prędkość – Access is granted in milliseconds, reducing congestion at busy entrances.
• Ideal for all ages – Easy for children, elderly residents, and visitors.
• Integracja – Works seamlessly with the indoor monitor and mobile app for a unified access control system.

How it works:

1. A resident approaches the entrance.
2. They present their registered card to the reader on the call panel.
3. The system verifies the card and triggers the electric lock.
4. The door opens, and the resident enters.

Cards can be easily managed—added, deleted, or suspended—through the indoor monitor or management software. The system supports multiple card types, including IC (13.56MHz) and ID (125kHz) cards, ensuring compatibility with existing credentials if needed.

2-Wire Connection: The Simplest Installation Available

Traditional video intercom systems often require 4 or more wires, plus separate power cables. This makes installation complex, expensive, and disruptive—especially in existing buildings. The FARHD 2-Wire system changes everything.

2-wire technology uses a single pair of standard two-core wires (≥0.5mm) to transmit power, video, audio, and control signals. Key advantages:

• Reuses existing wiring – If the building has old doorbell or telephone wires, they can often be reused, eliminating the need for new cables.
• Non-polarity – Connect the wires either way; there’s no risk of reverse polarity damage.
• Fast installation – Any electrician can complete the setup in under an hour.
• Lower cost – Saves on labor, materials, and disruption.
• Long transmission distance – Supports up to 100 meters, ample for most residential and commercial entrances.

For new construction, running a single 2-wire cable is quick and economical. For retrofits, the ability to reuse existing wiring is a game-changer, minimizing downtime and renovation costs.
