An apartment building’s entrance has an impossible job. It has to recognize hundreds of residents who expect instant, hands-free entry. It has to help visitors who have never seen the building find the right unit. It has to survive rain, dust, and temperature swings that range from bitter cold to direct sun. And it has to keep working when the resident population changes, when a card is lost, and when the property manager needs to update access on a Tuesday afternoon.

Most outdoor stations solve one or two of these problems well. FARHD’s new D43 is designed to solve all of them at once—combining advanced access control technology with the outdoor durability that apartment entrances actually require.

Designed for modern residential projects, the D43 is an ideal solution for apartment buildings and residential access control projects. Here is what it brings to the entrance.

1080P HD Camera: Clear Verification, Day or Night

The camera is where every access decision begins. If the resident cannot see who is at the door, the system fails at its most basic function.

The D43 is equipped with a 1080P HD camera with 2MP resolution and a 130° wide viewing angle, backed by infrared night vision.

In practice, that combination matters in three specific ways:

The wide viewing angle captures the full approach. A visitor does not stand precisely in front of a camera. They approach from the side, stand slightly off-center, or hold a package that occupies part of the frame. A 130° field of view captures the person and their context, so the resident sees enough to make a confident decision.

Infrared night vision extends usability past sunset. Apartment entrances are used heavily after dark—residents returning from work, deliveries continuing into the evening, guests arriving for dinner. Infrared night vision keeps the camera functional when ambient light drops, rather than degrading into an unusable image at exactly the moment security matters most.

1080P resolution supports identification, not just detection. Seeing that someone is at the door is not the same as identifying who. Higher resolution supports the practical tasks residents perform—recognizing a familiar face, reading a delivery uniform, checking a vehicle plate.

For integrators, camera performance is a commissioning question, not just a specification. The D43′s imaging should be verified at the actual entrance during the day, at night, and in backlit conditions—particularly at west-facing or glass-fronted lobbies where sunset light creates difficult conditions.

Five Access Methods: One Entrance, Many Users

No single access method serves every user in an apartment building. Residents want speed. Staff need managed access. Contractors need temporary credentials. Visitors need to call. The D43 supports five access methods, allowing each user group to take the path that fits them.

Face Recognition (Up to 40,000 Faces)

Face recognition gives residents hands-free entry—valuable when carrying shopping, a child, or a bicycle—and speeds up entry at high-traffic entrances.

The capacity for up to 40,000 faces is a meaningful figure for large residential projects. It means the system can serve very large communities—multiple buildings, thousands of households—without requiring a separate device or subsystem for face templates. For developers planning phased developments or large gated communities, that headroom matters.

As with any face recognition deployment, performance depends on enrollment quality, camera placement, lighting conditions at the entrance, and the matching threshold configured for the site. Enrollment should be voluntary, with card access available as an alternative, and privacy obligations for biometric data should be handled by the building operator with documentation of consent.

RFID Card

Card access remains the workhorse of residential entry. It is fast, familiar, and works for residents, staff, and contractors without requiring biometric enrollment or smartphone compatibility.

Because the D43 supports card access alongside the other methods, each household can allocate credentials the way it suits them—cards for domestic staff, face recognition for family members—and cards can be deleted promptly when someone leaves or a card is lost, closing the most common access control gap in residential buildings.

Mobile NFC

NFC unlock brings smartphone-based access to the building entrance. Residents can use a compatible phone to open the door without carrying a card—useful for everyday entry and for households where the phone is already the primary device.

Password

A password requires no card, no phone, and no enrollment—just a code. For apartment buildings, passwords are useful for temporary access when a contractor or delivery arrives and the resident is away, for guests who need short-term entry, and as a backup when a card is lost or a phone is unavailable.

And More

The D43 supports additional access methods beyond the four above, allowing the configuration to be adapted to the building’s requirements and the local market’s habits. For integrators specifying a system across a portfolio of buildings with different resident populations, this flexibility means one product platform can serve several project profiles.

Smart Elevator Integration

In apartment buildings, the entrance is only the first stage of access. Once a resident or verified visitor is inside the lobby, the next question is how they reach their floor—and whether they should be able to reach every floor or only their own.

The D43 supports elevator control protocol integration, allowing the intercom system to work with the building’s elevator control for floor access management. This is particularly relevant for:

High-rise residential buildings where unrestricted lobby access should not mean unrestricted floor access.

Buildings with private elevator lobbies where residents expect the elevator to recognize their authorization.

Premium residential projects where the entrance-to-elevator journey is part of the resident experience and the property’s positioning.

Mixed-use buildings where residential floors must be separated from commercial or public areas.

Elevator integration is a project-level requirement, not a plug-and-play feature—the specific protocol, elevator controller compatibility, and floor access rules need to be confirmed during specification. For integrators, raising this question early in the project prevents a late-stage discovery that the entrance system and the elevator system were specified independently.

Built for Harsh Environments

Apartment outdoor stations live outdoors. Not in a showroom, not under a canopy—outdoors, where the weather does what it does.

The D43 is built for that reality:

IP65 weatherproof protection — dust-tight and protected against low-pressure water jets from any direction, the appropriate baseline for an exposed building entrance.

Operating temperature from -40°C to +70°C — an unusually wide range that covers both extreme cold and direct-sun heat. For projects in northern climates, tropical markets, or locations where the entrance faces the sun for hours each day, this range is not a marketing number—it determines whether the device operates reliably in summer and winter alike.

A note for integrators: the IP65 rating is realized only when the cable entry is executed correctly. Proper glands, entry from below or from the rear where the structure allows, and a drip loop where cable approaches from above are installation practices that protect the rating in service. FARHD’s technical support group can advise on installation practices during commissioning.

Large System Capacity: Up to 9,999 Apartments

The D43 supports up to 9,999 apartments—a capacity that positions it for large residential projects rather than single-building deployments.

That scale matters for several reasons:

Large communities with multiple buildings and thousands of households can be served by a system designed for that size, rather than assembled from multiple smaller systems with separate directory structures.

Phased developments can expand without replacing the entrance infrastructure, because the capacity headroom is already there.

Directory management at this scale requires a structured approach to room numbering, directory generation, and call routing. The D43′s capacity aligns with FARHD’s experience in large-scale projects—supported by 28 direct sales branches across China, FARHD has completed over 10,000 large-scale building video intercom projects, including ultra-large communities with 1,000, 3,000, and even over 5,000 households.

For integrators, capacity headroom is a practical advantage: a system specified for 2,000 apartments today does not need to be replaced when the developer adds a third phase next year.

Flexible Installation: Wall-Mounted or Flush-Mounted

Installation flexibility is often underestimated in outdoor station selection, but it determines how well the unit integrates with the building’s architecture.

The D43 offers wall-mounted or flush-mounted installation options:

Wall-mounted installation suits retrofits, exposed walls, and situations where cutting into the structure is impractical or undesirable. It is faster to install and easier to service.

Flush-mounted installation suits new construction and high-end projects where the entrance should look integrated rather than attached. Flush mounting requires planning during construction—the back box and conduit must be provisioned before finishes are applied—but the result is a cleaner architectural appearance.

For developers and integrators, offering both options means the same product can serve different project types and different stages of construction, rather than requiring a separate SKU for each installation method.

Multilingual Support and Lock Compatibility

Two additional features round out the D43′s suitability for international residential projects.

Multilingual support allows the interface to serve diverse resident populations. In international communities—common in major cities, expatriate housing, and mixed-nationality developments—the interface language determines whether residents can use the system comfortably. Language settings should be configurable per surface (resident interface, visitor prompts, administrative functions) and should render complex scripts correctly.

Compatibility with different types of electric locks means the D43 can integrate with the locking hardware already specified for the building—electric strikes, magnetic locks, and gate controllers—rather than requiring a specific lock type. For integrators working across projects with varying lock specifications, this reduces compatibility risk at commissioning.

Where the D43 Fits

The D43 is designed for apartment buildings and residential access control projects. Its combination of features suits several project profiles:

Large residential communities — where capacity, face recognition, and multi-method access serve thousands of households.

High-rise apartment buildings — where elevator integration and floor access management are project requirements.

Premium residential developments — where flush mounting, camera quality, and access method flexibility contribute to the building’s positioning.

Mixed-use buildings — where residential floors require separated access and the entrance must serve both residents and commercial visitors.

International communities — where multilingual support is an operational requirement, not a feature.

Retrofit projects — where wall-mounted installation and card-based access allow the entrance to be upgraded without structural work.

Behind the Product: FARHD’s Manufacturing Foundation

The D43 is not a standalone product assembled from third-party modules. It comes from FARHD, a professional video intercom manufacturer founded in 1998 with 28 years of experience in video door phones and intercom systems.

FARHD specializes in full in-house R&D and production—from TFT LCD screens, driver boards, and camera modules to complete villa and apartment building intercom systems. That vertical integration supports the D43 in concrete ways: camera module performance can be tuned at the component level, interface rendering and multilingual support can be verified on the actual hardware, and customization for OEM and ODM projects can extend beyond branding and packaging to functional module adjustments and driver board configuration.

Products hold international certifications including CE, FCC, RoHS, IP65 water resistance, and EMC, supporting market access, customs clearance, and reliable outdoor performance. FARHD provides a hassle-free after-sales service system: upon product delivery, a dedicated technical support group is established to assist with programming, device installation, and wiring connections throughout the process.

For assembly partners, SKD solutions are available across Europe, the Middle East, South America, Southeast Asia, the United States, Russia, India, Iran, Turkey, South Korea, and Italy, helping reduce production and tariff costs.

A Modern Entrance for Modern Apartment Buildings

The D43 brings together the elements that apartment entrances actually need: a 1080P HD camera with infrared night vision, five access methods serving different user groups, elevator integration for floor access, IP65 protection and a -40°C to +70°C operating range for real outdoor conditions, capacity for up to 9,999 apartments, and flexible installation options. With multilingual support and broad lock compatibility, it is a practical solution for apartment buildings and residential access control projects worldwide.

For distributors, integrators, and developers evaluating the D43, the next step is a sample and a conversation about the specific project—building type, unit count, access method mix, elevator integration requirements, and installation conditions. Those details determine the configuration, and they are best discussed before the specification is finalized.
