ZKTeco SF400 Fingerprint Access Control Terminal in Dubai, UAE
A compact IP-based fingerprint terminal for controlled business entry, standalone door management, or integration with an access-control platform.
The SF400 combines fingerprint verification, optional card support, TCP/IP networking, Wiegand input and output, door-control interfaces, anti-passback capability, and an auxiliary linkage input. FourTeck can help buyers confirm the right credential version, door hardware, controller design, software environment, power, and project scope before quotation.
TCP/IP + USB Host
Wiegand In / Out
A practical biometric door terminal for controlled business entry
The SF400 is designed for organizations that want fingerprint-based identity verification at a door without automatically committing to a large multi-door architecture. It can work in standalone mode or on a network, and it can also participate in controller-based designs through Wiegand connections.
That flexibility matters in real projects. A small office may need one controlled staff entrance with an electric lock, exit button and door sensor. A larger site may already have an access-control controller and require the terminal to act as a biometric reader. Another buyer may want two devices arranged as master and slave so verification can be applied at both entrance and exit. The same model can therefore fit several deployment styles, but the wiring, credential version and management design should be confirmed before purchase.
ZKTeco specifies a 2.8-inch capacitive touch screen, its ZKFinger V10.0 algorithm, TCP/IP and USB host communication, storage for 1,500 fingerprint templates and 80,000 records, plus Wiegand input and output. Optional card capability is listed for EM or Mifare credentials with capacity up to 5,000 cards. Because both the fingerprint sensor type and card function can depend on the selected version, procurement teams should not assume every unit is identical simply because the front housing looks the same.
The access-control interface is also relevant to installation planning. The terminal can interface with an electric lock, door sensor, alarm, exit button and doorbell. An auxiliary input supports linkage with another source, such as an emergency switch or smoke detector, when the installation has been designed and configured for that function. Anti-passback capability can help organizations enforce a more controlled entry-and-exit sequence where the overall system design supports it.
For Dubai and UAE buyers, the main purchasing question is rarely just “Does it read fingerprints?” The more useful questions are whether the terminal matches the door hardware, whether the chosen credential option suits existing cards, whether the network and software environment are appropriate, and how users will be enrolled and managed. FourTeck can review those details before preparing a quote so the product is selected as part of a workable access-control solution rather than as an isolated device.
Why the SF400 fits focused access-control projects
Its value comes from deployment flexibility: biometric verification, network operation, direct door interfaces and controller integration can be combined according to the project design.
Fingerprint verification reduces dependence on shared credentials
A fingerprint is linked to an enrolled user rather than a physical card that can be lent to another person. For staff-only doors, records rooms, back offices or other controlled areas, this can provide a stronger basis for user accountability. Biometric access still needs good enrollment practice, user administration and an agreed fallback process, but it can help businesses move away from access that depends only on a transferable credential.
Capacity suited to many small and mid-size user groups
Support for up to 1,500 fingerprint templates and 80,000 records gives the device useful headroom for many office, branch, clinic, education and warehouse entry points. Buyers should still compare capacity with expected staff growth, enrollment practices and record-management requirements.
Wiegand input and output broaden integration choices
The terminal can communicate with compatible ZKTeco or third-party access controllers through Wiegand output, while Wiegand input also supports master-and-slave arrangements using two SF400 units. This gives system designers more options than a strictly standalone biometric reader.
Built-in door interfaces simplify single-door planning
Interfaces for electric lock, door sensor, alarm, exit button and doorbell make the device practical for a complete controlled-door workflow. The benefit is not merely having connectors; it is the ability to design a clear entry sequence in which verification, lock release, exit request, door state and alarm behavior are considered together. Final wiring should be planned around the lock type, power requirements and site safety rules.
Touch-screen management at the door
The 2.8-inch capacitive touch display provides a local interface for operational tasks. For smaller deployments, local management can be useful during enrollment, testing and basic administration, while networked environments can use supported software for broader management workflows.
Auxiliary input supports event-linked behavior
The auxiliary input can be used for a linkage function with an external source. This is relevant where the access-control design needs the terminal to react to a defined event, such as an emergency signal. The feature should be planned with the responsible security or life-safety integrator rather than assumed as a substitute for required fire or emergency systems.
The strongest reasons to shortlist this terminal
The ZKTeco SF400 Fingerprint Access Control Terminal is most compelling when a project needs biometric user verification and the installer wants freedom to choose between standalone operation, IP-managed deployment or Wiegand-based integration.
Its compact 105 × 105 × 32 mm body suits wall-mounted door locations where space is limited. The official operating range is 0 to 45°C with 20% to 80% humidity, so the physical environment should be checked carefully before placement. Buyers planning exposed outdoor installation should confirm protection requirements separately because the published SF400 parameter list does not state an ingress-protection rating.

For purchasing, three specification rows deserve extra attention: optional card support, communication method and door interfaces. If the site already uses EM or Mifare cards, confirm the exact card-compatible variant rather than assuming compatibility. If the device will be centrally managed, confirm how it will connect to the intended ZKTeco software and network. If it will directly control a door, provide the lock type, exit button requirement, door sensor, alarm linkage and power arrangement to the installer. These details determine whether the terminal can be deployed cleanly without last-minute accessory changes.
Configuration and buyer guidance
The most reliable way to buy the SF400 is to define the door and management workflow first, then match the terminal and accessories to it. A model number alone does not tell an installer which lock, card technology, network design or software workflow the project needs.
What exactly should happen at the door?
Define whether fingerprint alone is enough, whether card credentials are required, whether the user must verify when entering and leaving, and whether the terminal will release the lock directly or report to a separate controller. This is the highest-risk choice because it affects hardware, wiring and administration.
How many people will be enrolled?
Compare the 1,500-fingerprint capacity with the current user list and expected growth. Consider whether each person will enroll more than one finger and how often users are added or removed. Larger organizations may prefer a platform with more headroom or more centralized administration.
Does the site need card access too?
Card support is optional. If the organization already issues EM or Mifare credentials, confirm the intended card technology and the exact terminal version. Do not base the decision only on a generic product photo or an old quotation that does not state the credential type.
What network and software will manage it?
The official product information lists TCP/IP and compatibility with ZKBio CVAccess. ZKTeco also states in its support FAQ that remote fingerprint registration with ZKBio Time 8.0 is supported. Confirm the intended software version, server location, IP addressing, user permissions and whether the terminal network should be segmented from general office devices.
What accessories and power are required?
A functional controlled door may need an electric lock, suitable lock power supply, exit button, door contact, enclosure or mounting accessories, cabling and possibly an alarm interface. The SF400 itself is specified for DC 12V / 3A. The lock and other components should be engineered as a complete circuit.
Is the mounting location suitable?
Check temperature, humidity, exposure to sun or water, user traffic and physical protection. The published operating range is 0 to 45°C and 20% to 80% humidity. If the device will be exposed outdoors or in a harsh area, confirm whether another protected model is a better fit.
For a useful quotation, send FourTeck the model, quantity, door count, required credential type, existing lock or controller details, intended software, delivery location, target installation date and whether installation or configuration support is required. That information helps separate a simple device supply request from a complete access-control project.
Where this fingerprint terminal makes practical sense
The model is best suited to controlled business entry points where the user population fits its capacity and the environment matches the published operating limits. The use cases below focus on door access rather than broad surveillance functions.
Controlled staff entrances in offices and branches
For an office with a defined staff entrance, the terminal can provide biometric verification before the door is released. A standalone arrangement can suit a single controlled door, while TCP/IP management can help an administrator handle records and users through supported software. If the organization already has a central access controller, Wiegand output provides another integration path. The best design depends on whether one site or several sites will be managed and how user enrollment is handled.
Clinic and professional-area access
Clinics, laboratories, accounting rooms and professional offices often have doors that should be limited to authorized staff. The terminal can support this type of controlled entry where the device location is suitable and the organization has a clear process for enrollment, leavers and emergency release.
Warehouse office and restricted-room entry
A warehouse may not need biometric control on every door, but finance rooms, inventory offices, IT closets or staff-only areas can benefit from a defined entry point. Check the actual heat, dust and exposure at the mounting location before selecting this model for industrial sites.
Training center or education staff areas
Education environments may use biometric access for staff offices, records rooms, laboratories or administration areas. Capacity should be checked against the enrolled population, and policies should clearly define which users require biometric access rather than applying it to every door without a security reason.
Retail back-office control
Retail stores may use the device at back-office, cash-office or stock-control doors where customer access is not allowed. The installation should account for staff shift patterns, exit behavior, lock type and how records will be reviewed when managers need to investigate an access event.
Entrance-and-exit verification
Where a project requires user verification in both directions, two SF400 units can be configured in a master-and-slave arrangement through Wiegand input. Anti-passback capability can further support controlled movement logic. This should be designed as a system requirement, not added after installation without testing.
SF400 Network, Standalone and Controller Integration
The terminal is useful because it is not locked into one deployment model. It can operate on its own for a focused door requirement, connect by TCP/IP for network-based management, or use Wiegand to work with an access controller.
A standalone setup can be attractive for a single office door because it limits system complexity. A networked design is more appropriate when administrators need software-based management, record handling or coordinated user administration. Controller integration becomes important when the organization already has a structured multi-door access system and wants the SF400 primarily as a biometric verification endpoint. The correct choice depends on how many doors, users and sites are involved, who will administer the system and how much fault isolation the business expects.
SF400 Fingerprint Capacity, Records and Credential Planning
A capacity figure is useful only when it is compared with the organization’s enrollment policy. The SF400 supports up to 1,500 fingerprints and 80,000 transaction records, while optional card variants can store up to 5,000 EM or Mifare cards.
Suitable for many staff groups, but future growth and multiple enrolled fingers per person should be considered.
Busy doors generate records quickly. Decide how records are synchronized, exported and retained before the device reaches its limit.
Card support is not universal across every variant. Confirm EM or Mifare requirements in the quotation.
For a 100-person office, the fingerprint capacity may provide comfortable room for growth. For a large campus with many thousands of users, it may be better to consider a higher-capacity terminal rather than trying to divide users across devices without a clear management plan. The same principle applies to record storage: access events should be synchronized or exported as part of normal administration, not left indefinitely on the endpoint.
SF400 Door Interfaces, Anti-Passback and Event Linkage
The access-control interfaces make the terminal more than a fingerprint reader. It can participate in lock release, door-state monitoring, exit requests, alarm behavior and event linkage, while anti-passback can support stricter movement rules where the design requires them.
What the installer should decide
- Electric lock type and fail-safe or fail-secure behavior
- Separate lock power and protection requirements
- Door sensor position and open-door monitoring
- Exit button or request-to-exit workflow
- Alarm output purpose and receiving system
- Auxiliary input source and linkage logic
Why this matters to the buyer
A terminal can be technically compatible with a lock and still be poorly deployed if emergency release, door state, cabling, power or controller behavior is not planned. The purchase should therefore include the full door requirement, not just the reader.
Anti-passback also needs deliberate design. It is useful where the organization wants users to follow a valid entry and exit sequence, but it should be tested against real staffing patterns and exception procedures so legitimate users are not unexpectedly locked out.
What Buyers Should Check Before Purchase
The biggest purchasing risk is ordering the correct model name but the wrong project combination. Credential version, controller role, lock hardware, software, network design and installation environment should be checked together before the order is finalized.
Configuration Fit
Confirm whether the door needs fingerprint only or fingerprint plus card, and whether the terminal will work standalone, connect to software over TCP/IP or serve as a Wiegand reader for a controller. If two-sided verification is required, define the master/slave layout before cabling. User capacity should also be compared with expected growth rather than only today’s headcount.
Compatibility Check
List the existing lock, door sensor, exit button, controller, card technology, network switch and management software. If a legacy controller will receive Wiegand data, verify the expected format and wiring. If the site uses existing Mifare or EM credentials, confirm the card-capable SF400 version rather than assuming all units support the same card technology.
Availability and Warranty
Availability can change with supplier status, selected credential variant, quantity and project timing. Warranty terms can also depend on the source and regional supply channel. Ask FourTeck to confirm the quoted version, package scope, applicable warranty guidance, delivery expectations and any installation services before issuing a purchase order.
Quote Preparation
Share the quantity, number of controlled doors, user count, credential preference, lock and controller details, intended management software, installation location and required date. For project supply, also state whether cabling, power supplies, door accessories, commissioning or attendance-system integration are part of the requirement. A clear request produces a more useful quotation.
UAE availability, selection and delivery coordination
FourTeck supports product inquiries across Dubai and the UAE with assistance for model selection, configuration review, quote preparation, delivery coordination and warranty guidance. Current availability should be confirmed at the time of inquiry because supply can vary by credential version, quantity and supplier status.
If the terminal is part of a wider security project, FourTeck can also discuss the surrounding door hardware, network, cabling, controller and related access-control components. For broader planning, review FourTeck’s CCTV and access control systems in the UAE or contact FourTeck for product assistance.
Dubai, Abu Dhabi, Sharjah and Ajman project inquiries
Businesses in Dubai, Abu Dhabi, Sharjah, Ajman and other UAE locations can contact FourTeck for product availability, configuration guidance and quote assistance. The same buying checklist applies whether the requirement is one controlled office door or a multi-site rollout: confirm the model version, number of users, credential type, door hardware, software environment, delivery destination and support scope. Site conditions can differ significantly between a climate-controlled office and a warehouse entrance, so the exact mounting location should be included in the request. For broader IT and facility-security planning, buyers can also review FourTeck business IT and security services.
GCC and Africa access-control supply discussions
FourTeck also supports business technology inquiries across selected GCC and Africa markets through its regional channels. Organizations with requirements in Saudi Arabia, Qatar, Oman, Kuwait, Bahrain, Kenya, Uganda and other Africa-region locations can discuss the product requirement, quantity, controller design and delivery destination before supply options are confirmed.
Regional projects often introduce extra questions that a local one-door purchase may not have. A group with several branches may need consistent credential policy, software administration, network addressing and spare-unit planning. Warranty handling and delivery options may differ by destination, so they should be confirmed rather than assumed from a UAE quotation. If multiple sites use different card technologies or controllers, each site should be documented before the bill of materials is finalized.
For country-specific inquiries, businesses can use FourTeck Kenya, FourTeck Uganda, FourTeck Africa or FourTeck Kuwait. Availability, warranty and delivery arrangements remain destination dependent.
Other options buyers may consider
A different ZKTeco model may be more appropriate when the project needs Wi-Fi, video intercom, facial authentication or a larger biometric capacity. The decision should be based on the required authentication method and integration environment, not simply on choosing a newer-looking terminal.
ZKTeco F22
The F22 is another fingerprint access-control terminal and adds Wi-Fi among its published communication options. It may be worth considering where wireless network connectivity or its slimmer form factor is important. Credential capacity, interfaces and management requirements should still be checked against the exact project.
ZKTeco F35
The F35 is a standalone access-control terminal with a published video-intercom function and in-glass fingerprint verification. Consider it when the door workflow benefits from intercom capability in addition to biometric access.
ZKTeco SenseFace 4 Series
SenseFace 4 Series adds facial authentication alongside fingerprint and card functions in the published product family. It may suit projects that need more than fingerprint verification or that are moving toward a broader multi-biometric workflow.
8 Port PoE+ switch options
The SF400 is not specified as a PoE-powered endpoint, but access-control projects may still require network switches for controllers, cameras, intercoms or other IP security devices. FourTeck can help plan the broader low-voltage network where relevant.
Integrated CCTV and access control
For projects where controlled doors must be planned alongside cameras, recording, cabling and user permissions, it is better to review the complete security architecture rather than source each component independently.
Why business buyers contact FourTeck
Access-control purchases combine electronics, door hardware, network design and administrative policy. FourTeck’s role is to help organize those requirements into a clearer buying decision before commercial terms are finalized.
This approach is useful for SMBs, enterprise buyers, facility teams, contractors and procurement departments because it keeps technical assumptions visible before the purchase order. It also makes it easier to identify when a different biometric model, controller architecture or environmental rating would be more appropriate. Buyers can start with the FourTeck UAE website or send the project requirement through the contact page.
Common questions about the SF400
What is the SF400 used for?
It is used to verify users at controlled doors by fingerprint, with optional card support on applicable versions. It can operate as a standalone access terminal, connect to a network for supported management software, or work with an access controller through Wiegand. Common environments include staff entrances, offices, restricted rooms, clinics, education sites and back-office areas where user access needs to be controlled and recorded.
How many fingerprints can the device store?
ZKTeco publishes a fingerprint capacity of 1,500 and a record capacity of 80,000 for the SF400. When sizing a project, compare that limit with the number of people who need access, expected staff growth and the enrollment policy. If multiple fingers are enrolled per user or the site has a much larger population, FourTeck can help assess whether a higher-capacity model is more suitable.
Does it support cards as well as fingerprints?
Card support is optional rather than universal. The published specification lists up to 5,000 EM or Mifare cards for applicable versions. If your organization already issues cards, state the existing card technology when requesting a quote. FourTeck can help confirm whether the offered unit matches the credential requirement so the project does not end up with incompatible cards after installation.
Can the SF400 connect to an existing access controller?
Yes, the official product information lists Wiegand output, allowing the terminal to work as a reader with compatible ZKTeco or third-party controllers. The exact controller, Wiegand format, wiring and authentication workflow should be checked before purchase. Wiegand input is also available and can be used in a master-and-slave arrangement with two SF400 units for verification on both sides of a door.
Which software can be used with the terminal?
ZKTeco’s product page states that the SF400 can connect with ZKBio CVAccess for access-control and time-attendance management. ZKTeco’s support FAQ also states that the model supports remote fingerprint registration with ZKBio Time 8.0. Software versions, licensing, server requirements and integration scope can change, so buyers should confirm the intended platform before deployment rather than relying on an older installation guide.
Is it suitable for outdoor installation?
The published SF400 parameters state an operating temperature of 0 to 45°C and humidity of 20% to 80%, but the product page does not publish an IP ingress-protection rating for this model. Buyers planning an exposed outdoor door should therefore confirm environmental protection carefully. A sheltered location or another model designed for harsher conditions may be more appropriate depending on the site.
What should I provide when requesting a Dubai or UAE quote?
Provide the quantity, number of doors, expected user count, fingerprint-only or card requirement, existing controller or lock details, intended software, delivery location and target date. If you need installation, include the door type, exit button, door sensor, cabling and power status. These details help FourTeck prepare a more relevant quotation and identify missing accessories before ordering.
Can FourTeck help with bulk or multi-door projects?
FourTeck can review business and project inquiries that involve multiple units, doors or locations. For larger requirements, the useful starting point is a door schedule showing each location, credential method, controller arrangement, network availability, lock type and user group. Availability, warranty handling, delivery planning and installation scope can then be discussed against the actual quantity and destination rather than assumed from a single-device request.
Need Help Planning the Right Access-Control Setup?
FourTeck can review the required quantity, door hardware, user count, credential type, controller design, software, delivery location and support expectations before preparing a quote.
Share the model, quantity, number of doors, credential type, existing hardware and target date.
