Access control reader 2N Access Unit QR with CMOS Full HD camera, QR scanner, PoE (12.95 W), 8–12 V DC, 10/100 Ethernet

2N Access Unit QR is an access control reader with a Full HD CMOS optical sensor (1/2.7") and an integrated QR-code scanner. It supports credentialless entry using QR codes and also works with access chips or cards, fingerprints and PIN codes when integrated into a compatible system. The unit connects over 10/100 Ethernet and can be powered via Power over Ethernet (PoE, 12.95 W) or by a low-voltage DC supply (8–12 V). A built-in 2 W speaker provides audio feedback for users. The reader is available in black or silver finishes and is intended for secure entry in offices, residential buildings and other controlled facilities.

Advantages

The device combines a Full HD CMOS camera and a QR-code scanner in one compact access reader, enabling visual identification and contactless, credentialless entry. PoE support simplifies installation by allowing data and power over a single cable, while the option for 8–12 V DC power provides installation flexibility. Integrated audio output helps guide users at the door.

Suitable for

• Office entrances and reception areas
• Residential multi‑tenant buildings and gated communities
• Controlled facilities requiring visual verification and QR-based access
• Retrofit installations where PoE is available

When it may not be suitable

This unit is intended primarily as an access reader and relies on integration with access control systems for full functionality (chip/card, fingerprint and PIN support depend on system configuration). It may not be appropriate where standalone high-security biometric processing, long-range RFID reading, or weatherproofing beyond standard outdoor-rated readers is required.

Key specifications

• Camera: CMOS, 1/2.7" optical sensor, Full HD 1920×1080 resolution
• Scanner: integrated QR-code scanner for credentialless access
• Network: 10/100 Ethernet
• Power: Power over Ethernet (PoE) 12.95 W or 8–12 V DC
• Audio: 2 W built-in speaker
• Colours: black or silver

How to use

Mount the reader at the entry point following manufacturer installation guidelines and connect it to your network via Ethernet. If PoE is available, a single Ethernet cable provides both power and data; otherwise connect an 8–12 V DC supply. Configure the device within your access control system to enable QR-code-based entry and, where applicable, chip/card, fingerprint and PIN authentication. Use the built-in camera for visual verification and the speaker for user prompts and status feedback.

What to consider before purchase

• Ensure compatibility with your existing access control system for biometric, card or PIN integration
• Verify availability of PoE or plan for an 8–12 V DC power source
• Consider required environmental protection level if installing in exposed outdoor locations

Usage recommendations

For reliable QR-code reading, position the unit at typical user height and ensure good lighting at the entry; keep firmware updated and integrate the reader with your access management platform for centralized control and logging.
