Product Overview

DO-207B is a standalone proximity smart 125kHz RFID card reader with integrated keypad, engineered for single-door access control in both indoor and outdoor commercial environments. This unit combines a silicon keypad, Wiegand 26 communication, and relay output into a compact 86×86mm form factor, supporting up to 500 users with card, PIN, or card+PIN authentication. System integrators, security contractors, and facility managers deploy this reader for office buildings, staff entrances, storage rooms, and restricted zones where reliable contactless identification and keypad entry are required. The unit operates as a completely independent access controller, eliminating the need for a separate host controller in basic installations, while retaining Wiegand 26 input and output for integration into larger networked access control systems.

Key Features

• Standalone Access Control – Direct keypad programming for password, card, and user management without additional software or controllers.
• Wiegand 26 Compatibility – Supports both Wiegand 26 output and input, allowing the unit to function as a standalone controller or as a card reader connected to a central panel.
• Three Authentication Modes – Card only, PIN only, or card + PIN combination, providing flexible security levels based on site requirements.
• High-Sensitivity Reader – Detection response under 0.1 seconds, suitable for high-traffic door entry points where throughput matters.
• Password Override – Supports password-only door release, useful for maintenance access or backup entry when cards are not available.
• Exit Button and Doorbell Input – Built-in support for exit button and doorbell connections, simplifying wiring for standard door installations.
• Weatherproof Construction – Designed for outdoor and indoor use with silicon keypad sealing and durable housing rated for -20°C to 70°C operating temperature.
• User Capacity Options – Standard 500 users, with optional firmware supporting up to 1,000 or 4,000 users depending on project scale.

Technical Specifications

Industrial Applications

The DO-207B is purchased by security system integrators, access control distributors, commercial facility managers, and industrial project contractors who require a cost-effective, reliable standalone card reader with keypad for single-door installations. Common deployment scenarios include:

• Office and Staff Entrances – Replacing mechanical key locks with RFID card and PIN access for improved access logging and key management elimination.
• Warehouse and Storage Areas – Controlling entry to high-value inventory rooms where card-based authentication reduces unauthorized access risk.
• Apartment and Residential Common Doors – Providing tenants with card or PIN entry while maintaining centralized access records for property management.
• Industrial Restricted Zones – Securing control rooms, equipment rooms, and chemical storage areas where weather-resistant hardware is required.
• Educational and Institutional Buildings – Deploying in classrooms, labs, and faculty offices where simple standalone control is preferred over networked systems.

The reader’s standalone capability reduces installation complexity and wiring cost, making it a practical choice for projects where a central controller is not justified. Its Wiegand 26 interface also allows future migration to a centralized system without replacing the field hardware.

OEM / ODM Manufacturing Support

As a do rfid reader manufacturer, we offer OEM and ODM customization for the DO-207B to meet specific project requirements. System integrators and distributors who need consistent hardware for large-scale deployments benefit from our ability to customize housing color, logo printing, packaging, user capacity firmware, and authentication logic. OEM clients frequently request custom Wiegand output formats, modified relay timing, and branded faceplates for their proprietary access control solutions. Our engineering team works directly with project contractors to adapt the reader for compatibility with existing central panels, proprietary card formats, or specialized mounting requirements. This manufacturing flexibility ensures that wholesalers and system integrators receive hardware that matches their system architecture without requiring field modifications.

Factory Production Advantages

The do rfid reader manufacturer operates with stable production capacity suitable for both sample orders and bulk wholesale shipments. Every DO-207B unit undergoes in-house quality inspection before packing, including functional testing of the RFID read range, keypad response, relay switching, and Wiegand communication integrity. Production lead time for sample quantities is 1 to 5 days, while bulk orders ranging from 5,000 to 100,000 units are typically completed within 7 to 30 days depending on customization complexity. This production stability is critical for project contractors who need to coordinate delivery schedules with installation timelines and for distributors who maintain inventory for ongoing sales. Batch consistency is maintained through standardized assembly processes and component sourcing from qualified supply partners, ensuring that each shipment performs identically to the approved sample.

Bulk Supply & Project Deployment Support

Wholesale buyers and project integrators choose the DO-207B because it reduces per-door hardware cost without compromising reliability or compatibility. For large-scale deployments such as apartment complexes, office parks, or industrial facilities requiring 500+ doors, we provide bulk pricing, consolidated shipping, and technical documentation including wiring diagrams, programming guides, and integration notes. The reader’s standard 86×86mm form factor fits existing wall box cutouts, minimizing installation labor. Wiegand 26 compatibility ensures the reader works with most major access control panels, reducing integration risk. Our export logistics team coordinates with DHL, FedEx, TNT, UPS, and sea freight forwarders to meet project deadlines globally. Distributors benefit from consistent inventory supply and the ability to request custom packaging for local market distribution.

Why System Integrators Choose This Reader

Security system integrators select the DO-207B for projects requiring a proven, field-testable standalone reader that can also serve as a peripheral in a larger access control system. The silicon keypad offers reliable operation in outdoor environments where membrane keypads fail due to moisture ingress. The built-in relay directly controls electric door strikes or magnetic locks, eliminating the need for an external relay board in simple installations. When projects require later expansion, the same reader can be reconfigured as a Wiegand output device connected to a central controller, preserving the initial hardware investment. For distributors and wholesalers, the DO-207B represents a high-turnover SKU with broad application compatibility across residential, commercial, and industrial segments. The do rfid reader manufacturer supports long-term cooperation through consistent product revisions, backward compatibility, and responsive technical support for integration queries.
