When a video doorbell combines 1080P HD imaging, a 130° wide viewing angle, infrared night vision, and multiple unlock methods—including face recognition for up to 40,000 faces—it becomes more than a doorbell. It becomes a complete access control platform for apartment buildings, villas, and residential communities.

Modern residential projects demand more than a simple buzzer. Residents expect to see visitors clearly, communicate in real time, and unlock the door using the method that suits them best. Property managers need a system that is scalable, secure, and easy to integrate with elevators, access control, and building management platforms.

The FARHD 2MP 1080P HD Video Doorbell Intercom delivers all of this and more. With a 2-wire connection, IP65 weatherproofing, wide-temperature operation, and support for up to 9,999 apartments, it is engineered for the real-world demands of large residential developments.

This article explores the features, benefits, installation considerations, and applications of this advanced video doorbell intercom.

2MP 1080P HD Video: See Every Visitor Clearly

The core of any video intercom is its camera. The FARHD video doorbell features a 2MP 1080P HD camera, delivering sharp, detailed images that make visitor identification easy and reliable.

Why 1080P matters:

• Clear facial recognition – Identify visitors, delivery personnel, and guests with confidence.
• Detailed evidence – Record high-quality snapshots and video clips for later review.
• Professional appearance – A crisp video feed reflects well on the building and its management.

Whether it is a bright sunny day or a dimly lit corridor, the camera captures clear, usable video.

130° Wide Viewing Angle: No Blind Spots

A narrow camera angle can leave areas of the entrance uncovered. The FARHD video doorbell features a 130° wide viewing angle, capturing a broad view of the door and surrounding area.

Benefits of a wide viewing angle:

• Full coverage – See visitors standing to the side, not just directly in front.
• Package visibility – See deliveries left on the ground.
• Enhanced security – Monitor more of the entrance area with a single camera.

This wide field of view is especially valuable in corridors, lobbies, and gated entrances where people may approach from different directions.

IR Infrared Night Vision: Clear Monitoring After Dark

Security does not stop when the sun goes down. The FARHD video doorbell includes IR infrared night vision, automatically activating in low-light conditions to provide clear black-and-white video.

How it works:

• When ambient light drops below a threshold, the IR LEDs turn on.
• The camera switches to night mode, capturing clear images even in complete darkness.
• Residents can see who is at the door at any hour.

This feature is essential for buildings where visitors may arrive at night, and for residents who want peace of mind around the clock.

Multiple Unlock Methods: Convenience and Security for Everyone

Different users prefer different ways to unlock a door. The FARHD video doorbell supports a comprehensive set of unlock methods, ensuring that every resident, staff member, and visitor can gain access in the way that works best for them.

Unlock Method	Best For
RFID Card	Daily use by residents; fast, tap-and-enter access.
Mobile NFC	Tech-savvy users who prefer using their smartphone.
Password	Temporary guests, delivery personnel, or backup access.
Face Recognition	Hands-free access for residents; supports up to 40,000 faces.
Indoor Monitor	Answering calls and unlocking from inside the apartment.
App Remote Unlock	Letting in visitors when you are away from home.

Face recognition is a standout feature. With capacity for 40,000 faces, it is suitable for large apartment communities, office buildings, and gated communities. Residents simply walk up to the entrance, and the door unlocks automatically—no need to stop, search for a card, or enter a code.

---

Guard Mode & Indoor Screen Support

The system includes Guard Mode, a feature designed for buildings with security personnel or concierge stations. When a visitor calls, the guard station can receive the call, verify the visitor, and grant access—or forward the call to the resident.

Indoor screen support means that each apartment can have its own indoor monitor. Residents can see and speak with visitors, unlock the door, and manage access from the comfort of their home.

For property managers, this combination of guard mode and indoor screens provides flexibility and redundancy. If a resident is not home, the guard can handle the visitor. If the guard is unavailable, the resident can still answer from the indoor monitor or mobile app.

---

Elevator Control Protocol Integration

In high-rise apartment buildings, elevator control is a significant convenience and security feature. The FARHD video doorbell supports elevator control protocol integration, allowing the system to communicate with elevator controllers.

What this enables:

• After a resident verifies a visitor and grants access, the system can automatically call the elevator to the appropriate floor.
• Visitors are guided directly to the resident’s floor without needing to press buttons.
• Access is restricted to authorized floors only, enhancing building security.

This integration is particularly valuable in luxury apartments, high-rise towers, and gated communities where both convenience and security are priorities.

---

IP65 Weatherproof & Wide Temperature Operation

Outdoor devices must withstand the elements. The FARHD video doorbell is rated IP65 for dust and water resistance, meaning it is completely dust-tight and protected against low-pressure water jets from any direction.

Operating temperature range: -40°C to +70°C

This wide range ensures reliable operation in harsh climates:

• Freezing winters – No screen freeze, no button failure.
• Scorching summers – Stable performance without overheating.
• Rapid temperature swings – Sealed construction resists condensation and thermal stress.

Whether your project is in Russia, Northern Europe, the Middle East, Canada, or Southeast Asia, this video doorbell is built to perform.

---

2-Wire Connection: Simple, Reliable, Retrofit-Friendly

The FARHD video doorbell uses a 2-wire connection, transmitting power, video, audio, and control signals over a single pair of standard two-core wires.

Key advantages:

• Cable recommendation: ≥0.5mm – Standard two-core cable is widely available and inexpensive.
• Non-polarity – Connect either way; no risk of reverse polarity damage.
• Reuses existing wiring – Ideal for retrofits; often works with old doorbell or telephone wires.
• Transmission distance – Supports up to 100 metres, enough for most residential buildings.
• Power supply – Can be powered via the 2-wire connection or a 2-wire switch.

For new builds, running a single 2-wire cable is fast and economical. For retrofits, the ability to reuse existing wiring minimizes disruption and cost.

---

Lock Compatibility & Power Supply

The video doorbell includes 1 unlock relay, compatible with a wide range of electric locks:

• Electric lock (electric control lock)
• Motor lock (motorized deadbolt)
• Magnetic lock (electromagnetic lock)
• Electric strike lock (strike plate release)

Important: The relay is a dry contact and does not supply power to the lock. A dedicated 12V 5A power supply is required for the lock. This ensures reliable operation and prevents overloading the intercom system.

For fail-secure locks, the relay is typically wired using the NO (Normally Open) and COM terminals. For fail-safe locks, the NC (Normally Closed) terminal may be used. Always follow the lock manufacturer’s instructions.

---

Premium Build: Aluminum Alloy + IPS Glass Lens + Metal Rain Cover

The FARHD video doorbell is built to last, with premium materials and construction:

• Aluminum alloy housing – Durable, corrosion-resistant, and impact-resistant.
• IPS glass lens – Scratch-resistant and crystal-clear, ensuring sharp video.
• Metal rain cover – Provides additional protection against direct rainfall.

This combination delivers both durability and a premium appearance, suitable for high-end residential and commercial buildings.

---

Installation Options: Wall-Mount or Embedded

The video doorbell supports two installation methods:

• Wall-mount – Surface-mounted on the wall, easy to install and retrofit.
• Embedded – Flush-mounted into the wall for a sleek, integrated look.

Embedded installation is popular in new construction and high-end renovations, where a clean, minimalist appearance is desired. Wall-mount installation is faster and more flexible for existing buildings.

---

Multi-Language Support & System Capacity

The system supports English and custom languages, making it suitable for international projects and diverse residential communities.

System capacity: up to 9,999 apartments

• 1–4 digit room numbers – Flexible numbering to match any building layout.
• Scalable – Add more apartments as the building expands.
• Centralized management – Configure and manage residents from a single interface.

This capacity makes the FARHD video doorbell suitable for everything from small residential buildings to large apartment complexes and gated communities.
