A flexible identity point for attendance and controlled entry
For organizations that want one endpoint to handle everyday employee attendance and door access, the Horus E2-QR brings several credential methods into the same workflow. The current ZKTeco platform combines visible-light facial authentication, 125 kHz ID cards, 13.56 MHz IC cards, password entry and QR scanning on the QR variant. That gives an administrator more freedom to assign different authentication methods to staff, contractors, visitors or special operating scenarios without placing a separate reader at every point.
The terminal is built on Android 10 and uses an octa-core 2.0 GHz processor with 2 GB RAM and 16 GB ROM. For a buyer, the value of that platform is not simply the processor specification. It provides a modern device foundation for ZKTeco software integration and supported third-party development scenarios. The 5-inch TFT color touch display gives users a clear interaction surface, while dual 2MP cameras support face authentication. ZKTeco lists a face template capacity of 20,000, a card capacity of 50,000, a user capacity of 50,000 and an event capacity of 200,000, making the terminal suitable for organizations with substantial credential and attendance records.
Connectivity is another reason this model is relevant for multi-site businesses and buildings where the access point may not sit beside a network cabinet. The device supports TCP/IP, Wi-Fi on 2.4 GHz and 5 GHz bands, Bluetooth BLE 4.1 and 4G mobile communication. It also exposes Wiegand input and output, RS485, an auxiliary input, electric lock connection, door sensor, exit button and alarm connection. Those interfaces matter because a biometric terminal is rarely purchased alone; the buyer needs to understand how it will communicate with the network, door hardware, software and wider security design.
For UAE projects, FourTeck can help turn the model name into a practical bill of materials. The team can review whether the project is attendance only, door access only or a combined deployment; confirm whether the customer expects mobile QR credentials; check existing card technology and cabling; and discuss required quantities, mounting, power and software. This avoids selecting the QR variant when fingerprint is actually mandatory, or ordering a terminal before confirming how the existing lock, exit device and management software will fit together.
Why this model can simplify identity workflows
The strongest reason to consider this terminal is flexibility: one wall-mounted endpoint can support several identity methods, multiple network options and direct door-control interfaces. The business benefit depends on how those capabilities are planned into the real site.
Use the right credential for each user group
Face authentication can support regular employees, dual-frequency cards can preserve familiar badge workflows, passwords provide an additional method, and QR credentials can fit mobile or project-specific access scenarios. This is useful when an organization wants different user groups to follow different verification policies without installing several separate readers.
Room for larger user databases
Support for up to 50,000 users, 20,000 face templates, 50,000 cards and 200,000 transaction records gives administrators useful headroom for larger workforces, multiple shifts or access-event histories. Capacity should still be matched to the real software design and retention policy.
More ways to reach the management platform
Wired TCP/IP, dual-band Wi-Fi, Bluetooth and 4G support give system designers more choices when the terminal is installed in an office, branch, warehouse or temporary project area. The final network method should be chosen around signal quality, security policy and management requirements.
Connect to the physical door workflow, not only the network
Wiegand input/output, RS485, lock, door sensor, exit button, auxiliary input and alarm interfaces allow the terminal to sit inside a broader access-control design. That reduces the risk of buying an attractive biometric device that cannot be connected to the door hardware, reader arrangement or alarm behavior required by the site.
Fit attendance and access software
ZKTeco lists support for ZKBio Time and ZKBio CVAccess, with ZKBio Zexus used for mobile QR functionality. Selecting the management platform early helps the customer avoid duplicated user enrolment, unclear reporting or incompatible deployment expectations.
Support practical day-to-day control
Functions such as photo capture, event photo capture, holidays, anti-passback, record query, schedule bell and tamper alarm can support everyday workforce and access administration. Which functions are used should be decided during system configuration rather than assumed at purchase.
The QR variant is defined by credential flexibility
ZKTeco offers several Horus E2 variants, and the important buying detail is that each is not interchangeable. The E2-QR is the series option intended for face, card and QR use. It does not provide fingerprint template capacity, and it does not include the backup battery feature assigned to the E2-B variant. That distinction should be confirmed before a quotation is approved.
For teams evaluating the series, the QR function is not just a decorative scanner. ZKTeco specifically references the ZKBio Zexus mobile application and PDF417 scanning in third-party development projects. Buyers planning visitor credentials, mobile attendance or application-generated codes should explain the expected workflow so software and development requirements can be checked properly.
Up to 20,000 face templates with listed facial authentication under one second and 30 cm to 100 cm recognition distance.
Supports 125 kHz ID cards and 13.56 MHz IC cards as standard, useful when existing badge types must be considered.
TCP/IP, 2.4/5 GHz Wi-Fi, BLE 4.1 and 4G allow different communication designs for fixed or distributed sites.
Designed for wall mounting and compatible with Asian gang-box and single gang-box installations according to the manufacturer.

Choosing the correct configuration starts with the workflow rather than the capacity numbers. A company that already uses RFID cards may prioritize card compatibility and software migration, while a new office may want face authentication for employees and QR codes for approved visitors or mobile attendance. If the project needs fingerprint authentication, the E2-QR should not be selected on the assumption that all Horus E2 features are present in every version; the E2-FP is the series model built for fingerprint use. If power continuity at the terminal is a key requirement, buyers should also discuss how the door and terminal will be backed up, because the QR version does not include the E2-B battery feature. Network planning is equally important. Wired Ethernet may provide the cleanest permanent path in an office, while Wi-Fi or 4G can be useful where cabling is difficult, provided that security and signal quality are appropriate. FourTeck can review these decisions before preparing the final product request.
Plan the access workflow before you choose the terminal
The most important configuration decision is not the screen or memory size. It is the way users will be identified, how the terminal will connect to the door and network, and which software will own the attendance or access records.
Which credentials will users present?
List employee, contractor and visitor groups. Decide whether each group will use face, card, password, QR or a combined method. If fingerprint is mandatory, choose the correct series variant before quoting.
What is already installed at the door?
Document the electric lock, door sensor, exit button, existing reader, controller and power supply. This helps determine whether the terminal will operate as part of an existing architecture or a new access-control design.
How will the device reach the server?
Check Ethernet availability, Wi-Fi coverage, mobile signal, VLAN rules, firewall policy and remote-management requirements. Wireless connectivity should not replace proper security planning.
Which management platform is required?
Clarify whether the goal is time attendance, access control or both. Confirm ZKBio Time, ZKBio CVAccess, ZKBio Zexus or third-party development expectations before user enrolment begins.
What happens during a power or network outage?
The E2-QR does not include the backup battery used by the E2-B variant. Define UPS, access-control power supply and fail-safe or fail-secure door behavior according to the project design.
How many doors, sites and users are planned?
Share current and expected user numbers, number of terminals, site count, shift patterns and reporting needs. Capacity is generous, but management architecture and rollout planning still matter.
For a useful quote, send FourTeck the model, quantity, delivery location, approximate number of users, authentication methods, required software, number of doors, current card type, network method and whether installation or configuration support is expected. That information allows the quote to reflect the actual project rather than only the terminal hardware.
Where the E2-QR fits best
This model suits environments that value a choice of face, card and QR credentials while still needing conventional access-control interfaces. The best fit is a managed business deployment, not an isolated consumer door lock.
Corporate offices with mixed employee and visitor access
An office can enrol regular employees for facial authentication or cards while reserving QR credentials for approved visitors, temporary staff or mobile workflows. Because the same terminal also supports a door sensor, exit button and electric lock connection, it can become part of a controlled reception or office-entry design. The project team should still define visitor approval, QR creation, credential expiry, network segmentation and reporting rules in the management software.
Warehouses and shift-based operations
Large user and transaction capacities can support shift changes, contractor access and attendance records. Dual network choices are useful where the terminal is far from the main office network. Buyers should confirm placement, power protection and environmental conditions before installing near loading or production areas.
Education and training facilities
Schools, institutes and training centres can use card or face credentials for staff and QR-based workflows for specific visitors or temporary users. Access policy, privacy, user enrolment and data retention should be defined by the institution before deployment.
Clinics and service businesses
A compact wall-mounted terminal can support controlled staff entry and attendance without forcing every user to touch a fingerprint sensor. Face or card use may be more practical for busy administrative areas, while QR can be reserved for supported mobile scenarios.
Multi-branch businesses
Branches that cannot all use identical cabling may benefit from Ethernet, Wi-Fi or 4G communication options. Before standardising the model, the business should test the selected software architecture, user synchronization, remote support process and cellular-network suitability across each site.
Projects using mobile QR credentials or custom PDF417 workflows
The QR variant is most distinctive when the project genuinely needs QR-based authentication. ZKTeco identifies ZKBio Zexus mobile-app support and PDF417 scanning in third-party development projects. This makes the device relevant for organizations planning mobile credentials, controlled event access or application-generated codes, but it also raises an important integration question: who creates, validates and manages those codes? FourTeck recommends defining the software owner, credential lifecycle, network path and user experience before ordering a larger quantity.
ZKTeco Horus E2-QR Credential Flexibility
A practical access-control system should not force every user into the same identity method. The E2-QR gives administrators four main choices: face, card, password and QR. Each can serve a different operational role. Facial authentication can reduce dependency on carried credentials for regular users. Cards remain useful where employees already have ID or IC badges. Password entry provides another supported option, while QR can support mobile or project-specific workflows.
This flexibility matters most when the organization designs policy around user groups. A permanent employee may be allowed to use face or card, while a visitor might receive a time-limited QR credential generated through the relevant workflow. A contractor might use an existing card if it matches the supported frequency and enrollment plan. The terminal therefore becomes a policy endpoint rather than simply a face reader.
Buyer outcomes
- Reduce dependence on one credential type across all users.
- Keep compatibility discussions focused on actual card technologies.
- Use QR only where the supporting software workflow is clearly defined.
- Avoid buying the QR variant when fingerprint is a non-negotiable requirement.
- Make enrolment, visitor policy and fallback authentication part of the deployment plan.
For procurement teams, the key question is not whether the terminal supports many methods; it is which methods will actually be enabled and supported by internal policy. Before purchase, document how users will be enrolled, how credentials will be issued or revoked, whether multi-factor verification is required, who administers the database and what happens when a user cannot complete the preferred method. This turns a broad feature list into a predictable access process.
ZKTeco Horus E2-QR Connectivity and Door Integration
A biometric terminal is only useful when it can communicate reliably with both the management platform and the physical access environment. The E2-QR provides several communication paths: TCP/IP for wired networking, dual-band Wi-Fi for wireless LAN connectivity, BLE 4.1 and 4G mobile communication. For a single office, wired Ethernet may be the preferred path because it is easier to place inside a controlled network design. For branches, fit-out areas or temporary locations, Wi-Fi or 4G can offer more flexibility where new data cabling is difficult.
Choose based on cabling, VLAN policy, signal quality and remote-management needs.
Useful where supported mobile coverage fits the design, but SIM, band and data policy should be confirmed.
Lock, sensor, exit button, alarm, Wiegand and RS485 interfaces support a broader access-control layout.
The physical interfaces are just as important as network connectivity. A door design may need an electric lock, monitored door contact, request-to-exit device and alarm behavior. Some projects may involve an existing controller or external reader through Wiegand or RS485. Before purchase, the installer should produce a wiring concept that identifies which device powers the lock, how the terminal receives power, where the door sensor is connected and what the fail-safe or fail-secure behavior must be. The E2-QR uses DC 12V 3A and does not include the backup battery of the E2-B variant, so continuity planning should be handled at the system level.
ZKTeco Horus E2-QR Software and Operational Management
The terminal is designed to work within a management ecosystem rather than remain an isolated device. ZKTeco lists ZKBio Time and ZKBio CVAccess as supported software, while ZKBio Zexus is relevant to the mobile QR capability. The right choice depends on whether the organization is primarily solving attendance, door access or a combination of both. Buyers should define the reporting, user administration, device management and credential workflow before the first terminal is installed.
Operational functions such as photo capture, event photo capture, holiday schedules, anti-passback, record query, schedule bell and tamper alarm can add useful control, but they should be treated as configurable system functions. A facility team may care most about anti-passback and door monitoring, while HR may prioritize attendance records and schedule handling. IT may focus on network segmentation, server access and backups. Bringing these stakeholders together early reduces the chance that the device is installed correctly but the business process remains unclear.
Decision checklist
- Confirm which software will be the system of record for users and events.
- Define who can enrol faces, issue cards and generate or manage QR credentials.
- Decide whether attendance and access records need separate approval or reporting workflows.
- Plan device naming, site grouping, time settings, network access and administrative credentials.
- Document backup, support ownership and the process for replacing a terminal without losing operational continuity.
If a customer expects custom integration, PDF417 scanning or a third-party Android workflow, that requirement should be discussed separately from standard attendance or access setup. Development compatibility, APIs, credential formats and project responsibilities can vary. FourTeck can help organize the requirement for quotation and technical review, but custom behavior should not be assumed from the hardware model alone.
What Buyers Should Check Before Purchase
The biggest purchase risk is selecting the QR model because the series name looks familiar, then discovering that the required authentication method, door architecture, software workflow or power strategy is different from what the project needs. Confirm the full workflow before comparing price alone.
Configuration Fit
Confirm that face, card, password and QR are the intended methods. If fingerprint is required, the E2-FP is the relevant series option. If an onboard backup battery is a priority, discuss the E2-B variant or a system-level UPS strategy.
Compatibility Check
Check existing 125 kHz or 13.56 MHz cards, electric lock type, door sensor, request-to-exit device, controller, power supply, network and software. Do not assume an existing card or controller will work simply because the interface name is familiar.
Availability and Warranty
Availability, lead time, included accessories and warranty handling can vary by supplier source, order quantity and project timing. Request current terms for the exact E2-QR model rather than relying on a listing for another Horus E2 variant.
Quote Preparation
Provide quantity, user count, number of doors, credential types, current card technology, software requirement, network method, delivery location, target date and whether installation or configuration assistance is needed.
Buyers should also consider long-term operating cost. The terminal hardware is only one part of an access project. Door locks, power supplies, UPS protection, cabling, network ports, cards, software licensing or infrastructure, installation labour, custom integration and future support may affect the overall budget. If several sites are involved, standardizing naming, network rules and enrolment procedures can reduce administration later. For bulk or project supply, share the site list and rollout schedule so quantities and deployment assumptions can be reviewed together. If the E2-QR is not the best match, FourTeck can help compare another Horus E2 variant or a different access-control model based on the actual requirement rather than forcing the project around one SKU.
Procurement support for Dubai and UAE projects
FourTeck supports inquiries for the ZKTeco Horus E2-QR in Dubai and across the UAE with practical help before the order is prepared. Support can include confirming the requested variant, reviewing authentication methods, checking the intended software platform, discussing card and door compatibility, organizing a quotation and coordinating delivery based on the final order scope. Availability can change according to supplier status, quantity and project timing, so current supply should be confirmed when the quote is requested.
Review whether the QR, fingerprint or battery-focused series variant matches the real business requirement.
Coordinate the order after model, quantity, destination and timing are confirmed. No stock assumption is made before checking the current supply route.
Clarify the applicable warranty terms for the quoted supply and the process buyers should follow if support is required.
Support for Dubai, Abu Dhabi, Sharjah and Ajman
Businesses in Dubai, Abu Dhabi, Sharjah, Ajman and other UAE locations can contact FourTeck for product availability, configuration guidance and quote assistance. The same model can be used in very different projects, so the support discussion should begin with the site rather than the city name. A corporate reception, warehouse gate, school entrance and multi-tenant office may all require different credential policies, cabling, access hardware and software workflows even when the terminal is identical.
For a single-door requirement, provide the door type, existing lock, current cards, preferred authentication and network availability. For a multi-door or multi-site rollout, add a site list, quantities per location, expected user database, central management preference and target deployment schedule. FourTeck can then help organize the product and related requirements into a more useful quotation and highlight where installation, cabling, power protection or management software should be reviewed separately.
GCC and Africa inquiry support
FourTeck also supports business technology inquiries across selected GCC and Africa markets through its regional platforms and inquiry channels. Customers in Saudi Arabia, Qatar, Oman, Kuwait, Bahrain, Kenya, Uganda and other supported markets can share their requirement for review. Regional availability, delivery options, warranty handling, documentation and software support may vary by country, supplier route and project scope, so terms should be confirmed for the destination before ordering.
For cross-border or multi-country deployments, consistency becomes a key planning issue. Procurement teams should define whether every site will use the same card technology, QR workflow, server platform, naming structure and access policy. Mobile-network compatibility may also need country-specific review if 4G will be used. Standardizing the technical design while allowing for local installation and commercial differences can make ongoing administration easier.
Regional buyers can use FourTeck Kenya, FourTeck Uganda, FourTeck Africa or FourTeck Kuwait where relevant. Share the exact model, quantity, destination and project use so the appropriate regional team can review current options.
Other options buyers may consider
The best alternative depends on the missing requirement. If the project needs fingerprint authentication, backup power at the terminal or a different security architecture, choosing another variant can be more sensible than forcing the E2-QR into the design. FourTeck can also review the surrounding access-control, networking and installation requirements as one project.
ZKTeco Horus E2-FP
Consider the fingerprint variant when face, card and fingerprint are required together. It is the closer fit when fingerprint is a mandatory user method rather than QR.
ZKTeco Horus E2-B
Consider the battery-focused variant when local terminal backup is more important than QR scanning. The wider door power strategy should still be planned separately.
Standard Horus E2
Useful when face and card workflows are sufficient and the project does not require the dedicated QR or fingerprint variant.
PoE and network infrastructure
Access projects often need switching, VLANs, structured cabling and UPS planning even when the terminal itself uses a separate DC supply.
Complete CCTV and access control
Choose a wider project review when biometric access must be planned with cameras, doors, cabling, network segmentation and monitoring.
Why buyers contact FourTeck for access-control projects
Biometric terminals look simple on a product list, but successful deployment depends on the surrounding system. FourTeck helps business buyers organize the technical and commercial details before the quote so that hardware, access policy, software and site requirements are considered together.
Compare the QR, fingerprint, battery and standard variants based on the real authentication requirement.
Review card frequency, door hardware, network paths, management software and power planning before procurement.
Build the request around model, quantity, site, accessories and deployment expectations rather than a model name alone.
Coordinate destination and timing after current supply status and order scope are confirmed.
Explain the warranty terms that apply to the quoted supply and what documentation buyers should retain.
Consider cabling, switching, UPS, door hardware, access policy and software when the terminal is part of a larger security project.
The goal is to reduce avoidable mismatches. A low-cost hardware purchase can become expensive if the wrong variant is chosen, cards must be reissued, the door hardware is incompatible, the network is not ready or the software workflow was never defined. By sharing the project details early, procurement and technical teams can evaluate the complete requirement before approval.
Questions buyers ask about the Horus E2-QR
What is the Horus E2-QR used for?
It is an Android-based biometric terminal for time attendance and access control. The QR variant supports facial authentication, dual-frequency cards, passwords and QR credentials. It can connect to door hardware and management software, making it suitable for controlled office entry, workforce attendance, branch sites and other business environments where centralized user and event management is required.
Does the E2-QR include fingerprint authentication?
No. ZKTeco lists no fingerprint template capacity for the E2-QR. Buyers who require fingerprint authentication should review the Horus E2-FP variant instead. This is an important series distinction because the Horus E2 family shares many common specifications, but each variant is designed around a different additional function.
What QR functions are supported?
ZKTeco identifies QR support for the ZKBio Zexus mobile application and PDF417 scanning in third-party development projects. The exact credential workflow depends on the software and project design. If QR codes will be generated by a custom application, buyers should define the code format, validation method, network path and integration responsibility before ordering.
Can the terminal connect over Wi-Fi or 4G?
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 is often preferred for permanent controlled installations, while Wi-Fi or 4G may help where cabling is difficult. Network security, signal quality and management access should be reviewed before deployment.
What software can be used with the device?
ZKTeco lists ZKBio Time and ZKBio CVAccess as supported software, with ZKBio Zexus for the mobile application workflow. The correct platform depends on whether the customer needs attendance reporting, door access administration or both. FourTeck recommends confirming the intended software before enrolment and deployment planning begin.
Does it have a built-in backup battery?
The E2-QR is not listed with a backup battery. The battery-equipped model in the series is the Horus E2-B. If power continuity is important, buyers should plan a suitable access-control power supply or UPS and decide how both the terminal and electric lock should behave during an outage.
Is the Horus E2-QR available in Dubai and the UAE?
FourTeck can support UAE inquiries and quotation requests for this model. Current availability can vary according to supplier status, quantity, required accessories and project timing, so buyers should request a live quote rather than assume stock. Sharing the delivery location and required date helps the team review practical supply options.
What should I provide when requesting a quote?
Provide the exact model, quantity, user count, number of doors, preferred authentication methods, current card type, management software requirement, network method, delivery location and target date. If installation is required, add the door type, lock, exit button, door sensor, cabling condition and any existing controller details.
Can FourTeck help with a multi-site or bulk requirement?
Yes. For multi-site projects, FourTeck can review quantities, site locations, credential standards, network methods, software expectations and delivery planning before quotation. A consistent deployment plan is particularly useful when several branches must share the same user administration and reporting approach while using different local cabling or connectivity conditions.
Need Help Confirming the Right Horus E2 Variant?
FourTeck can review the intended authentication methods, user count, door hardware, current cards, software, network path, quantity, delivery location and warranty expectations before preparing a quote. This is especially useful when the choice is between QR, fingerprint, battery-backed or standard series models.
Share the model, quantity, number of users and doors, preferred credential methods, delivery location and required project support.
