ZKTeco Horus E2-B Multi-Biometric Terminal in Dubai, UAE
An Android 10 facial-recognition, card and password terminal built for workforce attendance and door-access projects that need flexible networking and battery-backed operation.
The E2-B is the backup-battery member of the Horus E2 family. It combines a touch interface, visible-light face authentication, dual-frequency card reading, wired and wireless communications, and access-control I/O in a wall-mounted design. FourTeck can help business buyers confirm whether this exact variant, the fingerprint E2-FP, or the QR-focused E2-QR is the correct fit before ordering.
A practical identity terminal for attendance and controlled entry
The Horus E2-B is a wall-mounted Android terminal designed to bring identity verification, time records and door-control functions into one compact endpoint. In everyday terms, it gives an organization a touch-screen device at an entry point where employees or approved users can authenticate by face, RFID card or password. The unit can then record transactions, exchange data with supported ZKTeco software and, when deployed for access control, connect to common door components such as an electric lock, door sensor, exit button and alarm interface.
Its value is not only in authentication capacity. The platform is built around Android 10 with an octa-core 2.0 GHz processor, 2 GB RAM and 16 GB storage, giving the device a modern application base compared with older keypad-only attendance terminals. A 5-inch TFT color touch display supports enrollment and daily interaction, while dual 2MP cameras and ZKFace VX5622 handle visible-light facial authentication. The manufacturer specifies up to 20,000 face templates, 50,000 cards, 50,000 users and 200,000 transaction records, which makes the terminal relevant to deployments where user count and event history extend well beyond a small-office clocking device.
The “B” variant matters during procurement. In the Horus E2 family, E2-B is the model associated with a removable lithium backup battery. It is not the fingerprint model: fingerprint template capacity is listed as not applicable for E2-B, while E2-FP is the variant intended for fingerprint authentication. QR scanning is likewise associated with E2-QR. That distinction is important because buyers often see family-level feature lists and assume every method is present on every chassis. Selecting by the exact suffix avoids paying for the wrong model or discovering a missing authentication method during installation.
For UAE organizations, FourTeck can help turn those specifications into an installable requirement. A useful pre-sales review covers how many users need enrollment, whether the project is attendance-only or door-control, which card technology is in use, whether Ethernet, Wi-Fi or 4G is preferred, what software will receive the data, where the terminal will be mounted, how backup power should be handled and whether readers or accessories are needed. This approach is especially useful for offices, warehouses, campuses, project sites and distributed facilities where network and door conditions may vary from one location to another.
Key benefits for security, HR and facility teams
The strongest reason to consider this terminal is the way it combines identity, connectivity and deployment flexibility in one endpoint. The benefits below explain where those capabilities can reduce operational friction for a real business.
Touchless face authentication supports faster daily movement
Facial authentication can reduce the need to handle a card or touch a fingerprint sensor for every event. ZKTeco specifies a facial recognition distance of approximately 30 cm to 100 cm and authentication in under one second for this variant. In a busy employee entrance, that can make arrival and exit routines feel more natural, provided the terminal is mounted correctly and enrollment is managed carefully.
Battery-backed design adds resilience to selected deployments
The removable backup battery is the defining reason to choose E2-B over the standard E2 when the project benefits from local power continuity or temporary-site flexibility. It does not replace proper electrical design, but it gives planners another layer to consider where short interruptions or movable operational setups are part of the environment.
Multiple connection methods reduce network constraints
TCP/IP, dual-band Wi-Fi, Bluetooth BLE 4.1 and supported 4G mobile communication give system designers more than one path for connectivity. A fixed office may prefer Ethernet, while a site where cable routes are difficult may evaluate wireless or mobile options. The correct method should still be validated against software, security policy and local coverage.
User and transaction capacity supports growing deployments
With published capacity for 50,000 users and 200,000 transactions, the device is not limited to a tiny team. Capacity headroom can matter for large workforce enrollment, multi-department attendance, contractors or locations where event logs accumulate before synchronization. Sizing should consider how records are transferred and retained in the management platform.
Dual-frequency card support helps mixed credential environments
The terminal lists support for 125 kHz ID cards and 13.56 MHz IC cards. That flexibility can be valuable where a company is migrating card populations or wants both face and card workflows. Buyers should still confirm the exact credential technology already issued to users, because frequency alone does not guarantee compatibility with every card implementation.
Door and software interfaces make one device useful in multiple project roles
The access-control I/O set includes Wiegand input/output, ZKTeco RS485, auxiliary input, electric-lock connection, door sensor, exit button and alarm interface. Supported software is listed as ZKBio Time and ZKBio CVAccess, with ZKBio Zexus on mobile. This gives integrators a practical base for either attendance-focused or controlled-entry projects, but every deployment should be mapped before purchase so readers, locks, software modules and network paths align.
What stands out in the Horus E2-B platform
The platform is notable for combining the functions normally evaluated separately in an attendance terminal, a facial reader and a compact access-control endpoint. Its 5-inch touch screen provides a more app-like operating experience than a basic keypad device, while the Android 10 base creates room for supported software workflows and third-party development scenarios. The processor, memory and storage are fixed platform characteristics, so buyers can focus their decision on authentication method, networking, door interface and deployment environment rather than choosing between multiple internal hardware performance tiers.
The model is also straightforward to position within its own family. Choose E2-B when the removable battery is important and face/card/password meets the authentication requirement. Choose E2-FP when fingerprint is mandatory. Choose E2-QR when QR-based workflows are required. That suffix-level clarity is more useful to a procurement team than a broad family claim because it directly influences the physical device supplied.

How to read these specifications before ordering
Capacity numbers tell you what the terminal can store, but they do not define the full system. A buyer should also decide where enrollment takes place, how user data is synchronized, whether the terminal is controlling a door or recording attendance only, and what happens when the primary network path is unavailable. For a door project, the lock type, exit method, door sensor and any additional reader should be checked as a complete circuit rather than purchased separately without an integration plan.
Variant selection is equally important. E2-B is the battery-equipped face/card/password model. If the requirement document states fingerprint or QR as mandatory, ask FourTeck to review the family options rather than assuming those methods are included in this SKU. This single check can prevent a common procurement mismatch.
Configuration and buyer guidance
The correct terminal is determined by the workflow around it, not just by the number of users. Before a quote is prepared, define the identity method, door role, software destination, network path and installation environment. These questions expose the details that most often change the required model or accessories.
Which authentication methods are mandatory?
If face, card and PIN are sufficient, E2-B is aligned with the published variant capabilities. If fingerprint is mandatory, the E2-FP should be evaluated. If QR is central to visitor or mobile workflows, evaluate E2-QR. Write the required methods into the purchase request so the suffix cannot be overlooked.
Attendance terminal or door controller?
Attendance-only deployments mainly need user enrollment, time events, software synchronization and reporting. Door-control deployments add lock, sensor, exit button, alarm and reader questions. The same terminal can participate in both scenarios, but the bill of materials and installation work are very different.
How will the device reach the management system?
Ethernet is often preferred for a fixed security endpoint when cabling is available. Wi-Fi can simplify locations without an easy network drop, while supported 4G can be relevant to project or remote scenarios. Choose one primary path and define security, signal quality, addressing and fallback expectations.
Will existing cards work?
The device supports 125 kHz ID and 13.56 MHz IC cards, but an existing credential program may have encoding, security or application details beyond frequency. Share a sample card specification or current reader model when compatibility must be maintained.
What software and reporting outcome is required?
ZKBio Time and ZKBio CVAccess are listed as supported. The project team should still confirm version, licensing, server or cloud architecture, attendance rules, reporting needs and any third-party integration before the hardware order is finalized.
How many sites, users and terminals are involved?
One terminal for a small office has different management and rollout needs from dozens of units across warehouses or branches. Provide quantity, site count, user population and expected transaction volume so procurement can plan device, software, accessories and deployment effort together.
For a useful FourTeck quote, send the exact model requested, quantity, number of users, whether the project is attendance or access control, preferred authentication methods, card technology if already deployed, software preference, network method, delivery location, target date and any installation requirement. If some of those details are unknown, FourTeck can help structure the questions before commercial options are prepared.
Ideal business use cases
This model is best understood through practical entry and attendance scenarios. The strongest fit is where face/card/PIN is appropriate, local user capacity is substantial, and the deployment benefits from flexible network choices or backup-battery capability.
Corporate offices with combined attendance and entry control
An office may want one employee credential process to support both clocking events and door access. Face authentication can reduce dependency on a physical card for routine use, while cards and passwords remain available for approved workflows. The access-control I/O enables the terminal to work with door hardware, and supported ZKTeco software gives the project a management layer. The planning priority is to define whether HR attendance and security access are managed together or by separate teams, because that affects user ownership, permissions and reporting.
Construction and temporary project sites
The removable backup battery and 4G capability make the E2-B worth evaluating for project environments where fixed network and power infrastructure may be less predictable than in a completed office. That does not make the terminal weatherproof or remove the need for proper enclosure and power design. Instead, it gives the deployment team more options when planning a controlled indoor or protected installation near site entry points.
Warehouses and logistics facilities
Warehouses often combine shift-based attendance with controlled staff access. A 50,000-user capacity is more than many single facilities need, but the transaction capacity and multiple network methods can be valuable for busy shift changes. Mounting location, lighting, door hardware, worker approach direction and network availability should be reviewed before installation.
Education and training environments
Campuses, training centers and administration buildings can use a terminal of this class for staff attendance or controlled rooms. The large user database can support substantial enrollment, but privacy, enrollment consent, access rules and separation between student and staff systems should be addressed as part of the deployment design rather than treated as a hardware-only issue.
Multi-branch workforce management
Organizations with several sites may value a consistent terminal family while choosing network methods according to each branch. The key question is not whether one device can store enough users; it is how identities, attendance events, access permissions and software synchronization will be managed across the estate. A pilot at one representative site can be useful before a larger rollout.
Facilities migrating from card-only access
A business that already uses RFID cards may want to add face authentication without abandoning cards immediately. The dual-frequency reader gives a path to evaluate mixed credential use. Before assuming existing cards can be reused, confirm their technology and how credentials are encoded. A migration plan should define enrollment, fallback methods and what happens to legacy readers at each door.
Horus E2-B Facial Authentication and Identity Capacity
For most daily users, the face workflow is the feature they notice first. The terminal uses ZKFace VX5622 with dual 2MP cameras and supplementary light, and the manufacturer lists face authentication in under one second with a recognition distance of roughly 30 to 100 cm. That combination is designed for a user to approach, present their face and complete the event without touching a sensor.
The buying question is not simply whether facial recognition is fast. A successful rollout also depends on enrollment quality, terminal height, approach angle, lighting conditions, user instructions and the privacy policy around biometric data. A large 20,000-template capacity is useful only when the organization has a clear process for creating, updating and removing identities.
Horus E2-B Flexible Connectivity for Fixed and Distributed Sites
Connectivity determines whether an attendance or access terminal is easy to manage after installation. The E2-B gives project teams several transport options: TCP/IP for conventional wired networking, 2.4 GHz and 5 GHz Wi-Fi for wireless LAN deployment, Bluetooth BLE 4.1 for supported local communication scenarios, and 4G mobile communication. This breadth is useful when a business has a mix of head-office, branch and project locations rather than one uniform network design.
The choice should be made at design time rather than after installation. Confirm firewall rules, addressing, SIM or data-service requirements, Wi-Fi credentials, security segmentation and the software endpoint. For multi-site deployments, standardizing the network method where possible can simplify support, while exceptions can be documented for locations that need 4G or wireless.
Horus E2-B Backup Battery and Door-Access Integration
The battery distinguishes this model from the standard Horus E2. ZKTeco’s current global specification lists a removable 3,200mAh lithium battery for E2-B. This makes the variant particularly interesting where short power interruptions, temporary operations or mobile project setups are part of the design. Buyers should treat the battery as a continuity feature for the terminal itself, not as a substitute for a complete access-control power strategy.
A door may include an electric lock, exit button, door contact, alarm interface and possibly an external reader. Those components have their own power and fail-safe/fail-secure considerations. If uninterrupted door operation is required during outages, the full circuit needs appropriate backup power and life-safety review. This is why a battery specification should not be interpreted as a promise that the entire controlled door remains operational.
Decision checklist
- Confirm whether backup is needed for the terminal only or the complete door hardware.
- Identify lock type, power draw and fail-safe/fail-secure requirement.
- Confirm whether an external reader is required and which interface it uses.
- Plan exit button, door sensor and alarm wiring before the wall is finished.
- Confirm the supplied battery revision and commercial package on the quotation.
What Buyers Should Check Before Purchase
The biggest purchase risk is choosing a Horus E2 family name without checking the variant suffix and the surrounding system requirement. E2-B is the battery-equipped face/card/password model. A correct order therefore starts with identity method, door role, software compatibility, network method and accessory list rather than model name alone.
Configuration Fit
Confirm face, card and PIN are the methods you need. Do not order E2-B for a fingerprint requirement; request review of E2-FP instead. If QR credentials are required for visitors or mobile access, evaluate E2-QR. Also check user count, card count and expected event volume against the published capacities.
Compatibility Check
Map the terminal to existing cards, software, network and door hardware. Share the current card type or reader model, planned ZKTeco software, Ethernet/Wi-Fi/4G preference, lock type and any external reader. A match on connector names alone does not guarantee the whole system will operate as intended.
Availability and Warranty
Ask for current supply status, supplied revision, warranty terms and what accessories are included. Battery capacity references have differed across regional documentation revisions, so the commercial quote should identify the actual unit and package being supplied. Avoid assuming a web specification automatically defines local stock or warranty conditions.
Quote Preparation
Provide quantity, site count, intended use, user population, authentication methods, software requirement, network method, door hardware, installation scope, delivery location and target date. For a bulk or project order, include whether units must be preconfigured or whether rollout support is required so the quote reflects the actual project.
Common question: is the E2-B suitable for a small office?
Yes, it can be suitable when a small office wants face/card/PIN attendance or controlled entry and values the richer connectivity and battery capability. Its large capacity does not force it to be used only in enterprise sites. However, a simpler ZKTeco terminal may be more economical if the office only needs basic attendance and has no requirement for 4G, Android integration or battery-backed operation. FourTeck can help compare the requirement rather than selecting solely by capacity.
Availability, configuration and service guidance
FourTeck supports ZKTeco Horus E2-B inquiries across Dubai and the UAE with help focused on correct model selection before purchase. Availability can vary according to supplier status, quantity, product revision and project timing, so the page does not assume ready stock. A quote request is the appropriate point to confirm current supply, commercial terms and the exact accessories or software scope required.
For projects that include installation, the team can also discuss mounting, network readiness, door interfaces and accessory requirements. The most useful request includes a simple description of how users will authenticate and what the terminal must control or report.
Support for projects in Dubai, Abu Dhabi, Sharjah and Ajman
Businesses in Dubai, Abu Dhabi, Sharjah, Ajman and other UAE locations can contact FourTeck for product availability checks, configuration review and quote assistance. The requirement may be a single terminal for an office entrance, a group of attendance devices for multiple branches, or a broader access-control project with locks, readers, exit devices and management software.
For multi-site projects, share the number of terminals per site and whether every location has the same network and door conditions. Standardizing a configuration can simplify rollout, but some locations may require a different connection method or accessory set. FourTeck can help identify those exceptions before the order is placed.
GCC and Africa availability guidance
FourTeck also supports business technology inquiries through selected GCC and Africa channels. Organizations with requirements in Saudi Arabia, Qatar, Oman, Kuwait or Bahrain, as well as markets such as Kenya and Uganda, can request regional guidance. Product availability, logistics, warranty handling, supplied revision and deployment support can vary by country, quantity and local supply conditions.
For a regional rollout, send one consolidated requirement that lists each destination, quantity, preferred authentication method, software platform and target schedule. This is especially useful when a company wants consistent attendance or access-control endpoints across several offices. A single model can simplify training and support, but mobile bands, network policy, local installation conditions and commercial terms should still be reviewed per country.
Other options buyers may consider
The nearest alternatives are other members of the Horus E2 family because they keep the same platform concept while changing the authentication or physical requirement. The right alternative is determined by what the users must present at the terminal, not by assuming the model with the longest feature list is automatically best.
ZKTeco Horus E2-FP
Consider E2-FP when fingerprint authentication is a stated requirement. The manufacturer lists fingerprint template capacity for the FP variant while E2-B does not include fingerprint capacity. This is the most important family comparison when a buyer has mixed biometric expectations.
ZKTeco Horus E2-QR
Evaluate the QR variant where mobile or PDF417 QR workflows are central to the application. It is a better direction than attempting to add an unsupported QR requirement to E2-B.
ZKTeco Horus E2
The standard E2 may suit projects that want the core Horus platform without the extended battery-focused B chassis. Compare power-continuity needs before choosing.
Broader ZKTeco access-control terminal range
A simpler or more specialized terminal may be more appropriate if the project does not need Android, 4G or the Horus capacity profile. Share the actual workflow so alternatives can be shortlisted.
Why business buyers contact FourTeck
Biometric terminals sit at the intersection of people, doors, networks and software. The purchasing risk is therefore higher than buying a standalone peripheral. FourTeck’s role can begin with product sourcing, but the more useful contribution is helping the customer describe the surrounding requirement well enough to avoid an unsuitable variant or incomplete accessory list.

Questions buyers ask about the Horus E2-B
What is the Horus E2-B used for?
It is used for time attendance and access-control applications where users authenticate by face, supported RFID card or password. The terminal can store user and transaction data, connect to supported ZKTeco management software and interface with door components such as an electric lock, door sensor and exit button. The exact use should be defined before ordering because attendance-only and door-control projects require different accessories.
Does the E2-B include fingerprint recognition?
No. ZKTeco lists fingerprint template capacity as not applicable for E2-B. Fingerprint authentication is associated with the Horus E2-FP variant. This is an important model-selection point because family-level descriptions may mention fingerprint as an option across the series. If fingerprint is mandatory, ask FourTeck to review the E2-FP or another suitable terminal before purchase.
What makes the E2-B different from the standard Horus E2?
The B variant is the battery-equipped member of the family and uses the longer chassis shared with E2-FP and E2-QR. ZKTeco’s current global information lists a removable lithium backup battery for E2-B. Buyers who do not require that capability can compare the standard E2, while those needing fingerprint or QR should evaluate the corresponding family variant instead.
Can it connect over Wi-Fi or 4G instead of Ethernet?
Yes. The manufacturer lists TCP/IP, dual-band Wi-Fi, Bluetooth BLE 4.1 and 4G mobile communication. The best option depends on the site. Wired Ethernet may be preferred for a permanent security endpoint, while Wi-Fi or 4G can help where cabling is difficult. Network security, signal quality, addressing and software reachability should be checked during design.
Which software can be used with this terminal?
ZKTeco currently lists ZKBio Time and ZKBio CVAccess as supported software, with ZKBio Zexus as the mobile application. A hardware purchase does not automatically define the software license or deployment architecture. Buyers should confirm the required product edition, version, server or cloud arrangement, number of terminals and reporting workflow as part of the project scope.
Can FourTeck help with door-control accessories?
FourTeck can review the requirement around the terminal, including lock interface, door sensor, exit button, alarm, external reader and network connection. The final accessory list is project dependent because door type, life-safety requirement, lock power and existing infrastructure vary. Share a simple door description or project drawing when available so the requested hardware can be checked together.
Is the terminal available for UAE business orders?
FourTeck accepts product inquiries and quote requests for UAE business requirements. Current availability can vary by quantity, supplier status, model revision and timing, so stock should be confirmed at the quotation stage. Provide the required quantity, delivery location and target date, along with the exact E2-B model, to receive a more useful availability response.
What information should I send for a bulk or project quote?
Send the model, quantity, number of sites, expected users, authentication methods, whether the terminals are for attendance or door access, existing card type, software requirement, preferred network method, installation scope, delivery locations and target schedule. If the project includes many doors, also describe lock and reader requirements. These details allow FourTeck to review model fit before commercial pricing is prepared.
Does the backup battery keep the entire access door working during an outage?
Not necessarily. The E2-B battery is a feature of the terminal. An electric lock, reader, exit device and other door hardware may have separate power requirements. If uninterrupted access-control operation is required, the whole door circuit needs appropriate backup power and design review. Ask for a complete power plan instead of treating the terminal battery as coverage for every connected component.
How do I choose between E2-B, E2-FP and E2-QR?
Start with the required authentication method. Choose E2-B when face, card and password are sufficient and the backup-battery design is valuable. Evaluate E2-FP when fingerprint is mandatory, and E2-QR when QR workflows are required. Then check network method, software, door interfaces and site conditions. FourTeck can review these points before you request the final quote.
Need help confirming the correct Horus E2 variant?
FourTeck can review the intended use, quantity, authentication methods, software, network, door hardware, delivery location and warranty expectations before preparing a quote. This is especially useful when a requirement document names “Horus E2” but does not identify whether battery, fingerprint or QR is the deciding feature.
Share: model or family, quantity, user count, attendance/access-control purpose, required authentication methods, software, network preference, delivery location and target date.
