Product Overview
The SF400 is designed to verify people at a controlled doorway using fingerprint credentials and, on supported versions, card credentials. Unlike a basic enrollment-only attendance clock, it includes physical access-control interfaces for an electric lock, door sensor, alarm, exit button and doorbell. That makes it suitable for projects where the terminal is expected to do more than record attendance: it can form part of the actual door-control workflow and can also communicate with other access-control components.
A key planning advantage is its ability to work in both standalone and networked modes. For a smaller location, administrators can use the device locally and move selected data with USB Host where appropriate. In a connected environment, TCP/IP allows the terminal to communicate over the business network with compatible management software. Current ZKTeco product-family information references ZKBio CVAccess, while older SF400 literature references ZKAccess 3.5. Organizations replacing an older installation should therefore identify the management platform already in use and confirm compatibility with the specific SF400 hardware and firmware being supplied.
Wiegand input and output broaden integration possibilities. The terminal can be used with compatible controllers, and ZKTeco documents master/slave arrangements using two terminals to verify users at entrance and exit. An auxiliary input can be used for linkage with an external source such as an emergency switch or detector, subject to correct system design and configuration. These capabilities are especially valuable when an installer must coordinate the biometric terminal with the rest of the door hardware rather than treating it as an isolated device.
For UAE buyers, the practical purchasing question is not simply whether the model name is correct. The quotation should match the required credential type, door hardware, software, mounting environment, power arrangement and project quantity. FourTeck.com can help procurement teams review those points, identify related accessories, prepare a clearer bill of requirements and coordinate availability information before an order is finalized.
Key Business Benefits
◆ Flexible Deployment
Standalone and networked operation gives a business options when planning a single controlled entrance, a branch office, or a wider system. A site can choose a locally managed approach where appropriate or connect the unit by TCP/IP for centralized administration through compatible software.
◆ Direct Door Integration
Interfaces for an electric lock, door sensor, alarm, exit button and doorbell help reduce uncertainty when building a complete door solution. Buyers can plan the terminal as an active part of the access system rather than purchasing a fingerprint reader without the required surrounding connections.
◆ Practical User Capacity
Capacity for up to 1,500 fingerprint templates is suitable for many office, education, clinic, warehouse and branch scenarios. Procurement teams can compare this confirmed limit with planned enrollment numbers and leave room for staff changes, contractors or future growth.
◆ Integration Headroom
Wiegand input and output support controller-based and master/slave designs. This is useful when an access project needs entry and exit verification, integration with existing compatible controllers, or a migration path that reuses parts of an established access-control infrastructure.
◆ Local and Offline Data Handling
USB Host provides a practical method for supported offline data operations. This can help in locations where administrators do not want to rely entirely on continuous network access, while still preserving the option of TCP/IP connectivity for managed environments.
◆ Better Procurement Planning
Because the unit exposes multiple door and integration interfaces, buyers can define the complete requirement before purchase: credentials, lock, sensor, exit device, emergency linkage, power, software and installation. This helps reduce missing-accessory surprises during deployment.
Product Highlights
A color graphical interface provides local navigation for user, access and system tasks. Touch-panel wording differs across vendor document revisions, so buyers should confirm the supplied version when that detail matters.
The documented optical sensor is rated at 500 DPI and works with the ZKFinger VX10.0 algorithm family, providing the biometric foundation for fingerprint enrollment and verification.
The transaction capacity gives administrators room to retain a substantial local event history before records need to be managed through the chosen operational process.
Supported SF400 variants are documented with capacity for up to 5,000 EM or Mifare cards. The exact card technology should be confirmed at quotation because it is not universal across every variant.
Vendor literature lists multiple verification methods and standard access-control functions such as time zones, holidays, access groups and unlock combinations, giving administrators more policy options than a simple single-mode reader.
Tamper protection, alarm outputs and an auxiliary linkage input can support a better-designed access-control workflow when connected and configured correctly with the wider security system.
One detail deserves special attention for replacement projects: current and legacy ZKTeco documentation is not fully identical. Some older material lists a resistive touch screen and references RS485 in feature descriptions, while newer product information may describe a capacitive screen and emphasizes TCP/IP/USB Host. Software references have also evolved. FourTeck recommends confirming the exact hardware revision, firmware and management platform expected for the project instead of assuming every unit carrying the SF400 model name is identical to every historical brochure.

The correct configuration should be chosen around the complete door requirement, not only the terminal specification. A fingerprint-only office entry may need a different package from a site that wants card plus fingerprint verification, entrance-and-exit confirmation, or integration with an existing access controller. The lock type, fail-safe/fail-secure behavior, exit method, door sensor, emergency release design and available power must be reviewed by the responsible installer. Networked deployments should also confirm IP addressing, switch connectivity and the management software version. If attendance reporting is required, define whether attendance will be administered locally, through the current ZKTeco platform, or integrated into another workflow. For multi-site procurement, confirm that the same hardware revision and credential technology are used across the order so enrollment and support processes remain consistent.
Configuration and Buyer Guidance
Before requesting a quotation, define what the doorway must do in normal operation and in an emergency. Start with the number of enrolled users, then decide whether fingerprint alone is enough or whether an optional card credential is required. If card use is planned, specify EM or Mifare rather than assuming the terminal includes the correct reader by default. Businesses replacing a previous biometric unit should also identify whether existing user cards, access controllers and management software need to remain compatible.
How many users will enroll?
Compare the expected user population with the 1,500-fingerprint capacity and plan spare capacity for joiners, contractors and future growth.
What controls the door?
List the electric lock, exit button, door contact, alarm and emergency-release requirements so the system can be designed as one coordinated door solution.
Will it connect to a controller?
If Wiegand is part of the design, state whether the terminal acts as a reader, uses another SF400 for entry/exit verification, or integrates with an existing compatible controller.
Which software is required?
Identify the exact management platform and version. Current product-family information and legacy documentation reference different ZKTeco software generations.
Is the site environment suitable?
The documented operating range is 0–45°C and 20–80% humidity. Installation location and enclosure planning should respect those limits.
What belongs in the quotation?
Include terminal quantity, lock hardware, power, cabling, exit devices, door sensors, software needs, installation scope and warranty expectations.
The most useful information to share with FourTeck.com is a short project brief: number of doors, approximate user count, preferred credentials, whether entry and exit both require verification, existing controller/software details, desired attendance reporting, and the delivery location. That gives the sales team a better basis for model confirmation and related accessory planning than a request containing only the terminal name.
Ideal Business Use Cases
Office Entrance Control
A company can use fingerprint verification to control staff access at a main office door while retaining event records. The door package should include the appropriate lock, exit method, sensor and power arrangement, with network management added when centralized administration is required.
Branch and Retail Back-Office Areas
For restricted staff-only rooms, back offices or branch entrances, the compact form factor helps where wall space is limited. A networked deployment can simplify administration when the business wants centrally managed users rather than isolated door-by-door operation.
Education and Training Facilities
Administrative offices, staff areas, laboratories or selected controlled rooms can use biometric verification where fingerprint access is appropriate. Capacity and reporting needs should be checked against actual enrollment and attendance requirements before rollout.
Warehouse and Operations Areas
A warehouse may use the terminal on supervised indoor access points to limit entry to authorized workers. Environmental conditions, mounting location and emergency release requirements deserve attention because operational areas can be more demanding than a standard office corridor.
Clinic or Professional Practice
The unit can help restrict access to staff areas, records rooms or controlled internal spaces where biometric enrollment is acceptable within the organization’s policies. Privacy, enrollment governance and local operating procedures remain the buyer’s responsibility.
Existing Controller Integration
Wiegand I/O makes the model relevant when a project already has compatible controllers and needs a biometric reader at the door. Confirm signal requirements, controller compatibility, wiring and firmware expectations before purchase.
The SF400 is not automatically the right choice for every access project. High-user-count sites, outdoor gates, environments outside its operating limits, or projects requiring modern facial, palm or mobile credentials may be better served by another terminal family. FourTeck.com can help compare alternatives when the required credential method, environmental rating or system scale falls outside this model’s practical fit.
ZKTeco SF400 Fingerprint Verification and User Capacity
Fingerprint enrollment is the core of this terminal, so capacity planning should start with people rather than doors. The documented limit of 1,500 fingerprint templates makes the unit appropriate for many small and medium business environments, but the way an organization enrolls users affects how quickly that capacity is consumed. If policy requires more than one finger per person, the practical number of enrolled individuals can be lower than the raw template count. Buyers should therefore estimate current staff, contractors, temporary workers and expected growth rather than treating 1,500 as a simple headcount.
The optical sensor is documented at 500 DPI and uses ZKFinger VX10.0-family processing. For business operations, the important point is consistent enrollment quality and clear user procedures. Administrators should enroll fingerprints carefully, keep the sensor clean, define what happens when a user cannot verify successfully, and decide whether optional card credentials or another method will be used as a fallback. Physical access systems need an operational exception path; otherwise a failed biometric read can become a door-access problem rather than a simple attendance inconvenience.
The 80,000-record capacity provides local space for transaction history, but retention planning still matters. A connected site should define how often records are collected, who is responsible for reviewing them and how long the business needs to retain data outside the terminal. A standalone site using USB workflows should document the export process and assign responsibility so event data does not remain only on the device indefinitely. These procedural details help the hardware deliver reliable business value instead of becoming an unmanaged endpoint on the wall.
ZKTeco SF400 Door Control and Integration Flexibility
A significant strength of the model is that it provides interfaces required around a controlled door rather than stopping at biometric recognition. Vendor specifications list connections for an electric lock, door sensor, alarm, exit button and doorbell. For an installer or project engineer, this means the terminal can participate directly in the access workflow, but those interfaces must be matched to the selected door hardware and site safety design. Lock voltage, current, relay arrangement, fail-safe or fail-secure behavior and emergency egress requirements should be reviewed by a qualified installer.
Wiegand input and output add another layer of flexibility. ZKTeco documents the ability to connect the terminal with compatible controllers and to use two units in a master/slave arrangement so users can be verified at both entrance and exit. That can support anti-passback designs where the project requires controlled movement tracking. The exact controller, firmware and wiring topology should still be confirmed before equipment is ordered because Wiegand compatibility is a system-level requirement, not merely a connector checkbox.
The auxiliary input is intended for linkage with an external source such as an emergency switch or detector. In practical terms, this can help coordinate access behavior with an emergency event when the feature is enabled and the system is designed correctly. Buyers should never assume the terminal alone provides a complete life-safety solution. Emergency release requirements, fire-alarm integration and local code compliance need to be handled within the overall building and security design. FourTeck can help identify the product interfaces during pre-sales review, while the final implementation should follow the approved project design.
ZKTeco SF400 Network, Software and Administration Planning
TCP/IP connectivity allows the terminal to sit on an IP network and communicate with a compatible management platform, while USB Host can support offline data handling. The choice between these approaches should reflect how the business actually operates. A single small office may be comfortable with local administration, but a group of doors or branch sites usually benefits from centralized user management, scheduled data collection and consistent access policies.
Software version is especially important because ZKTeco documentation for this long-running model spans more than one platform generation. Older SF400 material references ZKAccess 3.5, while current ZKTeco family information references ZKBio CVAccess. A replacement buyer should not assume that an existing application, database or integration will automatically accept a newly sourced terminal. Capture the current software name, version, database environment and any custom integrations before ordering. If the device will be installed on a managed corporate network, involve the IT team early so IP addressing, VLAN placement, firewall rules and administrative access can be planned correctly.
USB operation can be useful for isolated environments, but it should be governed by an internal procedure. The organization should decide who can use removable media with the device, where exported attendance or access records are stored, and how data is protected. Networked administration similarly benefits from role-based access and documented account ownership. These are not glamorous product features, yet they often determine whether an access-control deployment remains manageable after installation. A well-prepared quotation should therefore include both the terminal hardware and the administrative environment in which it will be used.
What Should You Know Before Choosing This Access Terminal?
The questions below focus on the practical details that decide whether the terminal fits a real project: user capacity, credentials, integration, software, door hardware, environmental limits and quotation preparation. They are designed to help technical evaluators and procurement teams identify issues before equipment reaches the installation stage.
Is the capacity suitable for a growing office or branch?
It can be suitable when the planned fingerprint enrollment stays within the documented 1,500-template limit. Count templates rather than only employees, because organizations that enroll multiple fingers per person consume capacity faster. Include future staff, contractors and replacement enrollments in the estimate, then compare the result with the available capacity before standardizing the device across multiple doors.
Can the terminal use cards as well as fingerprints?
Supported variants are documented with optional capacity for up to 5,000 EM or Mifare cards. Buyers should specify the required card technology because the card function is variant dependent. If an organization already has staff badges, provide the card type and sample credential details so compatibility can be reviewed rather than assuming existing cards will work automatically.
Will it work with an existing access controller?
Wiegand input and output provide integration options with compatible controllers, and the device can also participate in master/slave arrangements. Compatibility still depends on the controller model, signal configuration and system design. Share the existing controller brand, model, wiring arrangement and intended reader role before purchase so the deployment can be checked at a system level.
Which management software should a buyer plan for?
The correct software depends on the hardware and firmware revision. Legacy documentation references ZKAccess 3.5, while current ZKTeco family information references ZKBio CVAccess. A business replacing an older terminal should record its present software version and integration requirements, then confirm support for the exact device offered before migration or expansion.
What door hardware should be included with the terminal?
A complete access point may need an electric lock, power supply, exit button, door sensor, alarm linkage, emergency release device and suitable cabling. The SF400 exposes interfaces for several of these components, but they are not automatically a complete installation kit. Ask for a quotation based on the whole doorway so critical accessories are not missed.
Can it verify users at both entry and exit?
ZKTeco documents a two-terminal master/slave approach using Wiegand so verification can occur at entrance and exit, with anti-passback functionality available in supported configurations. This is more involved than a single-reader door. Buyers should define whether exit verification is mandatory and have the installer confirm controller, cabling and emergency-egress requirements.
Is it appropriate for outdoor or high-temperature installation?
The published operating range is 0°C to 45°C with 20–80% humidity. That does not by itself establish an outdoor weather rating. UAE projects should therefore review the actual installation position, direct sunlight, enclosure, dust, moisture and ambient temperature. If the site exceeds the documented environment, another terminal or protected installation approach may be more appropriate.
What should be checked when replacing an older SF400?
Check the existing display/hardware revision, firmware, card reader type, software platform, network settings, Wiegand role, power supply and door wiring. Documentation has changed across the product’s lifetime, so a like-for-like model name does not guarantee identical implementation details. A replacement should be evaluated against the installed system, not only the label on the front.
What information helps FourTeck prepare a more accurate quotation?
Share the number of doors, estimated user count, fingerprint/card preference, existing controller and software details, required entry/exit behavior, lock type, exit device, door sensor, network availability, installation location and project quantity. Also state whether supply only or broader deployment coordination is required. This reduces ambiguity and helps identify accessories or alternative models early.
Business Requirements to Match Before You Buy
Different buyers describe the same access-control need in different ways. These requirement-led examples show where the SF400 can fit and what should be confirmed before purchase.
For businesses that need fingerprint door access with attendance records
The terminal combines biometric verification with access-control interfaces and transaction storage. Confirm the reporting software and attendance workflow so the device is not purchased only for a capability the organization cannot administratively use.
For a branch that needs standalone operation today and networking later
Standalone and TCP/IP operation provide deployment flexibility. Plan network addressing, administration rights and software compatibility early if centralized management may be introduced after the initial installation.
For projects that must reuse an existing access controller
Wiegand I/O can support compatible controller integration. Provide the controller model and intended signal role so the installer can verify interoperability before the order is placed.
For teams replacing a legacy biometric door reader
Record current wiring, software, card technology and firmware expectations. A replacement project is smoother when the team compares system dependencies rather than assuming the same model family behaves identically across revisions.
For sites that want entry and exit verification
A documented master/slave arrangement can support verification in both directions. Confirm cabling, anti-passback requirements, emergency egress and the physical placement of both terminals before procurement.
For procurement teams buying a complete door package
Ask for the terminal together with the required lock, power, exit device, door sensor, cabling and software considerations. This gives finance and project teams a clearer total requirement than pricing the biometric terminal alone.
What Buyers Should Check Before Purchase
A biometric access terminal is only one part of a working doorway. Before requesting a quote, buyers should confirm the exact model revision, credential method, user capacity, software environment and all connected door components. This is particularly important when the purchase is a replacement or an extension of an existing system. A terminal that looks correct on paper can still create extra work if its card reader, firmware or management software differs from the installed environment.
Configuration Fit
Confirm fingerprint template requirements and whether the optional EM/Mifare card version is needed. If multiple verification methods are part of company policy, document the expected credential combinations before procurement.
Compatibility Check
Record existing controller, Wiegand configuration, management software, card credentials and network design. For a replacement, include photos or wiring notes from the installed access point where appropriate.
Door and Power Requirements
The terminal needs the correct DC power arrangement and should be planned with the electric lock, door contact, exit method, alarm and emergency release requirements of the site.
Availability and Warranty
Do not assume stock, bundled accessories or warranty duration from an old listing. Ask FourTeck to confirm the current source, supplied package and warranty terms in the quotation.
Installation Scope
Clarify whether the requirement is product supply only, installation-ready equipment, migration from an existing terminal, or a complete access-control package that needs coordination with cabling and door hardware.
Quote Preparation
Provide door count, user count, credential type, software, network availability, lock details, delivery location and order quantity. For project supply, include rollout phases and required documentation.
Long-term operating cost should also be considered. Although the terminal itself does not carry a subscription requirement in the basic specification, management software, integration work, replacement power supplies, locks, cards, installation labor and future hardware support can affect the project budget. A buyer comparing several terminals should therefore review the complete access point and administration model rather than selecting solely by device price. FourTeck.com can help structure the inquiry so procurement, IT and facilities teams evaluate the same requirement.
UAE Availability and Service Support
FourTeck.com supports ZKTeco access-control inquiries in Dubai and across the UAE with assistance for product identification, configuration review, quote requests, delivery coordination and warranty guidance. Availability can change according to hardware revision, credential option, supplier status, project quantity and the specific package requested, so the current quotation should be treated as the authoritative source for lead time and supplied components.
For a simple replacement request, the most useful starting information is the existing model label, software platform and a description of the connected door hardware. For a new project, provide the number of doors, expected users, fingerprint/card requirements, network environment and whether attendance reporting is required. FourTeck can then help identify whether the SF400 is appropriate or whether another ZKTeco terminal better matches the project’s capacity, credential or environmental requirements.
Warranty terms should also be confirmed before purchase rather than inferred from a generic online listing. The applicable coverage can depend on the supplied source and commercial terms. If the project requires installation or configuration assistance, mention that in the inquiry so those requirements can be reviewed separately from hardware supply. For purchasing support, use the contact page below and include your company, project location, quantity and target deployment schedule.
Coverage for Business Buyers Across the UAE
Businesses in Dubai, Abu Dhabi, Sharjah, Ajman and other UAE locations can contact FourTeck.com for product availability, configuration guidance and quote assistance. The same preparation principles apply whether the requirement is one office entrance or a multi-site rollout: confirm the exact model revision, user and credential requirements, door hardware, software environment, quantity and delivery destination. For project orders, sharing a simple door schedule or bill of quantities can make the review more efficient and help identify missing locks, exit devices, sensors, power supplies or related access-control components before purchase.
FourTeck’s role is to help buyers match the requested hardware with the business requirement and coordinate commercial information. Final installation design, life-safety interfaces and site compliance should be handled by the responsible project team and installer.
Regional Availability for GCC and Africa Projects
FourTeck.com also supports business technology inquiries for selected regional requirements beyond the UAE. Procurement teams working on projects in Saudi Arabia, Qatar, Oman, Kuwait and Bahrain can submit model, quantity and deployment details for sourcing review. For East Africa and wider Africa-region inquiries, the relevant FourTeck regional channels can be used to discuss supply options, delivery requirements and project-specific support. Availability, commercial terms, warranty handling and delivery arrangements vary by destination, supplier source and order size, so each request should be assessed individually.
Regional projects benefit from standardization. If the same biometric terminal will be deployed in several countries, confirm that all units use the same credential option, firmware expectations and compatible management software. Also plan spare units, power accessories and documentation where the project requires consistent support across sites. A central bill of quantities can help the purchasing team compare like-for-like configurations instead of receiving different device variants under the same broad model name.
Other ZKTeco Options Buyers May Consider
The best alternative depends on whether the project needs a similar fingerprint terminal, a different credential mix, a more modern biometric method or another installation format. The options below are useful starting points for comparison. Final specifications and availability should be checked for the exact model required.
ZKTeco SF300
Consider when evaluating another compact fingerprint access-control option in the same broader product family.
ZKTeco F18
A widely used fingerprint access-control model to compare where form factor, integration and credential requirements differ.
ZKTeco F22
Useful for buyers comparing another ZKTeco fingerprint terminal where deployment style or connectivity priorities may differ.
ZKTeco SpeedFace-V5L
Consider for projects moving beyond fingerprint-only access toward a newer multi-biometric terminal family.
For broader projects, buyers can also review business access-control solutions or contact FourTeck product assistance with a door schedule and user requirement. Alternatives should be chosen according to credential method, environmental rating, user capacity, software ecosystem and controller design rather than model popularity alone.

Frequently Asked Questions
What is the SF400 used for?
It is an IP-based fingerprint terminal for door access control and time attendance. It can verify users at a controlled entrance, store transaction records and connect to supported door hardware. Depending on the deployment, it can operate standalone or communicate over the network with compatible management software.
How many fingerprints can the device store?
The documented fingerprint capacity is 1,500 templates. If your policy enrolls more than one finger for each person, the practical number of individual users will be lower than 1,500. Plan capacity around actual enrollment policy and expected growth rather than employee headcount alone.
Does it support RFID cards?
ZKTeco documentation lists optional card capacity of up to 5,000 EM/Mifare credentials on supported variants. Card capability is configuration dependent, so buyers should specify the card technology required and confirm that the quoted unit contains the correct reader before ordering.
Can FourTeck help confirm the correct version?
Yes. Share the intended credential type, existing software, controller details and door hardware. This is particularly important because ZKTeco documentation from different periods varies on some hardware and communication wording. The current quotation should identify the supplied option as clearly as possible.
Does the terminal connect directly to a door lock?
The specification includes an interface for an electric lock as well as a door sensor, alarm, exit button and doorbell. A complete installation still needs correctly selected power, lock and safety components. The final wiring and egress design should be confirmed by the responsible installer.
Can it integrate with another access controller?
Wiegand input and output provide options for compatible controller integration and documented master/slave deployments. Confirm the controller model, signal requirements, firmware and wiring topology before purchase. A Wiegand interface indicates integration capability, but it does not guarantee compatibility with every controller configuration.
Is the terminal available for UAE projects?
FourTeck.com can review current UAE sourcing and quotation options. Availability can vary according to revision, card option, quantity and supplier status, so stock and lead time should be confirmed in the current commercial offer rather than assumed from a generic product listing.
What warranty applies to the SF400?
Warranty terms depend on the supplied unit, source and quotation. FourTeck can provide warranty guidance as part of the sales process. Buyers with project or support requirements should state their expected coverage so it can be considered before the purchase is finalized.
How do I request a quote?
Use the FourTeck contact page and include quantity, number of doors, approximate user count, required credentials, existing controller/software details, delivery location and any lock or accessory requirements. This helps the team prepare a more relevant quotation and identify whether another model should also be considered.
