A Connected Entrance Platform for Modern Facilities

A doorway is both a physical boundary and an important communication point. Staff need to know who is requesting entry, visitors need a clear way to reach the correct person, security teams need dependable event information, and building managers need a controlled method for issuing or revoking access. A simple lock may restrict entry, but it does not provide visual verification, remote communication, event records or integration with wider systems. This product family is designed to bring those functions together in a compact IP-connected device.

Each unit combines a high-resolution camera, microphones, a loudspeaker, access credential support and network connectivity. This means the entrance can participate in a broader security and communications environment rather than operating as an isolated doorbell. A visitor can call a reception point or compatible SIP endpoint. An authorised user can present a card, use NFC or Bluetooth, receive a temporary credential, or follow another configured method. An administrator can review activity, manage users and adjust permissions through supported management tools. Video can be viewed live, stored locally on a supported card or integrated with a compatible recording platform.

The three-model design is useful because not every entrance has the same operating pattern. The GDS3725 adds a numeric keypad and broader connection options for sites that need PIN entry or deeper integration with door-control infrastructure. The GDS3726 keeps a rugged metal enclosure and provides a visitor doorbell button for reception-led entry. The GDS3727 uses a lighter compact enclosure and adds dual-band Wi-Fi 6, which can help where a wired data connection is difficult, although power and installation planning still remain necessary. Choosing correctly is therefore about the door workflow, not simply selecting the model with the longest feature list.

For African organisations, deployment conditions may include outdoor exposure, dust, rain, heat, public-facing entrances, mixed network quality and different levels of on-site technical support. The IP66 protection rating across the range helps with environmental resistance, while vandal-resistance differs between the metal and plastic models. Buyers should still plan a suitable mounting position, weather protection where appropriate, surge protection, cable routing, reliable power and secure network configuration. FourTeck helps turn these technical points into a practical procurement list so that the order includes the correct station, mounting accessories, credentials, PoE provision, lock interface items and deployment support.

Key Business Benefits

The strongest value comes from combining several entrance functions in one managed solution. The cards below explain what the capabilities mean for business operations, security teams and facility managers.

Product Highlights That Matter During Selection

All three stations use a 1/3-inch 4MP HDR sensor with video output up to 1920 × 1080 at 30 frames per second. The lens provides a 127-degree horizontal, 70-degree vertical and 152-degree diagonal field of view, helping the camera cover a broad doorway scene. Wide dynamic range up to 120 dB is useful when a visitor stands against bright outdoor light or when the entrance has a mixture of shade and sun. Six white LEDs support low-light viewing, while the PIR detection range is listed at approximately three to five metres.

The stations use a 10/100 Ethernet interface with integrated IEEE 802.3af Class 3 PoE. BLE 5.0 is included across the family, while dual-band Wi-Fi 6 is exclusive to the GDS3727. Security and provisioning capabilities include encrypted configuration support, TLS, SRTP, HTTPS, 802.1X and remote provisioning options. These controls are valuable, but they must be used correctly: administrators should change default credentials, limit management access, use current firmware, isolate facility devices appropriately and document every integration point.

Physical differences are equally important. The GDS3725 includes a 15-key numeric keypad and is suited to PIN-based workflows. The GDS3726 includes a doorbell key and keeps the stronger metal enclosure. The GDS3727 also uses a doorbell key, but its smaller plastic enclosure and Wi-Fi 6 capability target compact or cable-constrained deployments. Final selection should consider the desired credential flow, vandal exposure, existing controllers, wiring and the people responsible for ongoing management.

Technical Specifications

Configuration and Buyer Guidance

Begin with the entrance workflow. Decide who uses the door, how often it is used and what should happen when a visitor arrives. Employee-only doors may rely mainly on RFID, NFC or Bluetooth. Public reception doors may need a visible call button connected to reception or security. Shared residential or mixed-use buildings may need temporary visitor credentials and remote opening. High-control environments may prefer PIN entry in addition to other credentials. Once the workflow is clear, the model choice becomes much easier.

For project quotations, provide the number of doors, preferred models, expected users, credential types, lock details, network environment, recording requirement, installation location and delivery destination. This information helps FourTeck identify missing accessories and reduces the risk of receiving a price for an incomplete solution.

Ideal Business Use Cases

The platform is suitable where entrance security, communication and event visibility need to work together. The following use cases show how the three models can fit different operating environments without assuming that one station is right for every door.

The practical question is not whether the product can be mounted at a door, but whether the complete workflow fits the people, risk level, physical hardware and support process. FourTeck can help compare variants and related devices when a different access-control architecture would be more appropriate.

GDS3720 Video Intelligence and Doorway Visibility

Door cameras operate in difficult lighting. A visitor may stand in shade while bright daylight fills the background. Indoor lighting can reflect from glass, while evening scenes may have only limited illumination. The 4MP HDR sensor, wide dynamic range and white-light LEDs are designed to help the station produce a usable image across these changing conditions. The wide field of view also reduces the chance that a person standing slightly to one side is missed.

The series produces video up to 1920 × 1080 at 30 frames per second and supports H.264 profiles plus Motion JPEG. For the buyer, this means the station can provide live visual communication and security footage without being treated as a simple low-resolution doorbell camera. ONVIF Profile S support can help with compatible surveillance platforms, while a microSD card of up to 256GB can provide local storage. Exact retention depends on recording mode, resolution, frame rate, event frequency and card capacity, so storage days should be calculated rather than guessed.

AI-based motion detection and behaviour-analysis functions can support proactive monitoring, but intelligent alerts must be tuned to the scene. A busy pavement, moving vegetation, vehicle headlights or reflective surfaces may create unnecessary events if the detection zone and sensitivity are not configured carefully. Site testing during daytime and night-time is therefore part of a good deployment. Security staff should also decide which alerts need immediate action and which should simply be recorded for later review.

Privacy is another important operational issue. The camera should view the entrance area required for access control without capturing unnecessary private spaces. Recording notices, retention periods and user permissions may be governed by local policy or law. FourTeck can help buyers identify the technical storage and integration questions, while the customer remains responsible for approving the legal and organisational policy for the final site.

GDS3720 Access Methods and Visitor Workflows

Access control is most effective when each user group receives an appropriate method. Permanent employees may use RFID cards, NFC or Bluetooth. Residents may prefer mobile access. Contractors can receive time-limited credentials. Visitors may call reception or use a temporary QR code or password. PIN entry is available through the GDS3725 keypad, making that model useful where numeric credentials are part of the policy. The GDS3726 and GDS3727 focus on a doorbell-led visitor experience.

Supporting many methods does not mean every method should be enabled. A simpler, documented policy is usually easier to manage. The administrator should define who may issue credentials, how identity is confirmed, how long temporary access lasts, and how lost cards or phones are handled. A credential should be linked to a named person or role rather than shared without accountability. When someone leaves the organisation, access should be revoked as part of the same offboarding process used for email, applications and physical keys.

The SecureAccess app can support remote opening, visitor video calls, temporary passwords, live views and access administration. The base package is described by the vendor as supporting up to ten users without a licence fee, with paid add-on capacity available for larger user counts. Buyers should confirm current licensing, mobile-platform support and account requirements at the time of deployment because software terms can change. For larger buildings, an administrator should also test notification delivery, mobile connectivity and the response process when a visitor calls outside normal working hours.

The correct workflow balances convenience and control. Mobile credentials can reduce physical card handling, while cards remain simple for staff who do not use personal phones. QR codes can be useful for guests, but expiry and forwarding risk must be considered. PINs are convenient but can be shared. FourTeck helps buyers discuss these trade-offs and select the model that supports the intended policy rather than adding unused features.

GDS3720 Network, SIP and Security Integration

A smart door station becomes more valuable when it communicates with the systems already used by the organisation. SIP support allows visitor calls and intercom sessions to be integrated with compatible Grandstream or third-party IP communications platforms. ONVIF Profile S can support video integration. Relays, alarm inputs and outputs allow the station to work with door contacts, exit buttons, alarms and other control components. The GDS3725 adds Wiegand input and output for projects that need a connection to compatible legacy or external access-control equipment.

Integration should be proven in a test environment before a large rollout. Confirm that the intended answering device shows video, receives audio, sends audio back and can trigger the correct door-release command. Check what happens if the call is unanswered, if the network is unavailable or if the primary reception point is closed. For multi-door projects, define naming conventions so operators can immediately identify which entrance is calling. Avoid using generic labels such as “Door 1” when a clear site and location name would reduce response errors.

Network security matters because the station controls a physical boundary. Place facility devices in an appropriate VLAN, limit management access, use strong unique administrator passwords, enable secure protocols, keep firmware current and monitor unusual events. Where remote management is enabled, use the supported secure service rather than exposing the web interface directly to the public internet. Back up configuration information and document IP addresses, extensions, relay assignments and recovery procedures.

Power design is also part of reliability. PoE can simplify cabling and centralise backup through a protected switch, but the PoE budget and cable quality must be checked. Outdoor cables may need surge protection and correct earthing according to the site design. The door lock can have separate power requirements from the station. FourTeck can assist with a procurement checklist, while a qualified installer should validate electrical, fire and emergency-release compliance for the specific building.

What Buyers Should Check Before Purchase

A model number alone is not enough for a complete access-control quotation. Before ordering, buyers should confirm the operating workflow, physical door hardware, network design, credential policy and support expectations. This protects the project from common problems such as missing relays, incompatible locks, insufficient PoE, unsuitable mounting, incomplete credentials or a station that cannot connect to the intended answering point.

Africa Availability and Service Support

FourTeck supports product enquiries across Africa with assistance for model selection, configuration review, quotation, delivery coordination and warranty guidance. Availability may vary according to the chosen GDS3725, GDS3726 or GDS3727 model, supplier position, quantity, accessories and destination. A current quotation is therefore the correct way to confirm commercial terms rather than relying on a general online listing.

For a single-door requirement, the discussion may focus on the station, power, mounting and lock interface. Multi-door or multi-site projects usually need a wider plan covering credentials, network segmentation, reception endpoints, recording, administrator roles, spare units, deployment sequence and handover documents. FourTeck can help organise the procurement side of that plan and coordinate related IT equipment where required.

Delivery support depends on the destination, order size and available shipping route. Buyers should provide the full destination and required timeline at the beginning of the enquiry. Warranty guidance can include checking the applicable coverage, documentation and return route, but final terms will be stated on the quotation or supplied documents. Installation, configuration and commissioning needs should also be identified separately so the customer understands what is included.

Africa Country and Regional Coverage

Businesses across Africa, including Kenya, Uganda, Nigeria, Ghana, Tanzania, Rwanda, Ethiopia, South Africa, Zambia, Botswana, Senegal and nearby regional markets can contact FourTeck for product availability, model guidance and quote assistance. Requirements can differ between a corporate reception in a capital city, an outdoor warehouse entrance, a school gate, a residential development or a remote branch, so the enquiry should describe the actual site rather than only the country.

FourTeck can help customers review the suitable variant, related mounting parts, credentials, PoE provision, intercom endpoints and project quantities. Delivery timing, taxes, import requirements and warranty handling may differ by destination and will be clarified during the quotation process. Regional buyers planning a standard design for several countries should also identify local power, cabling, installer and compliance differences before choosing one bill of materials for every site.

For local support routes and broader procurement information, visit FourTeck Kenya, FourTeck Uganda or the main FourTeck Africa technology platform.

GCC, Middle East and Africa Availability

FourTeck Africa can support enquiries for organisations operating across Africa while coordinating wider technology requirements through selected FourTeck platforms for GCC and Middle East markets. Customers with regional branches may need a consistent access-control design across Africa, UAE, Saudi Arabia, Qatar, Oman and Bahrain, but product availability, delivery options, warranty handling and installation responsibilities can vary by country.

A regional project should start with a shared technical standard and a country-by-country commercial check. The technical standard can define the approved model, firmware approach, credential method, network VLAN, naming convention, recording policy and administrator roles. The commercial check can then confirm local supply, shipping, tax, power accessories, installation labour and support route. This approach reduces configuration differences while still respecting local conditions.

Businesses needing Gulf procurement coordination can review FourTeck UAE. Share all target countries, quantities and required delivery windows in the initial request so the team can separate confirmed options from configuration-dependent items and provide a clearer procurement path.

Other Options Buyers May Consider

Related products should be selected by workflow. Some buyers need a keypad, some need a simple visitor button, and others need an indoor control endpoint, PoE or credentials. The cards below show the main alternatives and supporting categories to discuss with FourTeck.

Why Buyers Choose FourTeck

Technology procurement is easier when the supplier understands the complete requirement rather than treating every enquiry as a request for a box. A video door station affects the physical door, network, security policy, user credentials, reception process and ongoing administration. FourTeck helps buyers organise those elements before a quotation is finalised.

FourTeck supports small businesses buying one entrance device, integrators preparing a project bill of materials and enterprise teams standardising several locations. The level of assistance can be matched to the request: a simple availability check, a model comparison, an accessory review or a broader procurement discussion. Buyers remain responsible for approving design, local compliance and installation, while FourTeck provides practical product and commercial guidance.

The best enquiry includes enough information to avoid assumptions. Share door count, site type, user count, preferred opening methods, existing systems and delivery location. The response can then focus on the actual business need instead of sending a generic catalogue list.
