Product Overview
For commercial and light-industrial installations requiring a compact, all-in-one access control solution, the 2N Access Unit 2.0 (Axis part number 02137-001) combines an IP-based door controller and 125 kHz RFID card reader into a single wall-mount unit. Eliminating the need for a separate controller box, it reads EM4x02 and HID Prox card formats and supports NFC-based door opening from compatible mobile devices. Equipped with a PoE 802.3af input alongside an optional 12 V DC supply, it draws power directly from the network switch, keeping cabling tidy and installation straightforward. It also includes 2 configurable inputs, relay outputs for door strike or magnetic lock control, a 97 dB buzzer, an inbuilt tamper switch, and a web-based administration interface for network-managed user access and event reporting. With an IP54 weatherproof and IK08 impact-resistant housing, the unit is suitable for both indoor lobbies and sheltered outdoor entry points. Note: this product is listed as discontinued.
Key Capabilities
Integrated Controller and Reader
Combining the door controller and RFID reader in a single wall-mount unit reduces hardware count, simplifies installation, and removes the need for a separate back-end controller enclosure at smaller access points.
125 kHz RFID with NFC Support
Reads EM4x02 and HID Prox 125 kHz cards, covering two of the most common legacy card formats in commercial deployments. NFC support also allows compatible smartphones to trigger door release without a physical card.
PoE-Powered Network Device
Powered via PoE 802.3af (Class 0, up to 12.95 W) with 12 V DC as an alternative, the unit connects to a standard network switch without a separate power adaptor, cutting cable runs and keeping the installation clean.
IP54 and IK08 Rated Housing
The IP54 rating provides protection against dust ingress and water splashing, while IK08 impact resistance handles contact or accidental knocks at an entry point. Suitable for sheltered outdoor doors as well as internal lobbies and corridors.
Relay Outputs and Configurable Inputs
Active switch output at 8-12 V DC up to 600 mA, plus passive NO/NC relay contacts rated up to 30 V / 1 A AC/DC, give installers flexibility to drive electric strikes, magnetic locks, or turnstile gates directly. Two configurable inputs allow door contact or REX button connection.
Best For
- Single-Door Commercial Entry Points: The integrated controller-reader design suits offices, server rooms, and secure storage areas where one controlled access point is needed without a large rack-mount controller.
- HID Prox and EM4102 Card Environments: Sites already issuing 125 kHz HID Prox or EM4x02 credentials can deploy this unit without re-issuing cards, as both formats are natively supported.
- Sheltered Outdoor Entry Doors: With IP54 weatherproofing and IK08 impact resistance, the unit handles sheltered building entry doors, car park stairwells, and covered access gates where exposure to dust and moisture is a factor.
- Network-Managed Access Systems: The web-based administration interface and network connectivity make it suited to IT-managed environments where access events, user lists, and reporting are handled centrally rather than from a local keypad.
Why Choose the 2N Access Unit 2.0
Where many access control deployments require a separate panel controller plus a reader head, the 2N Access Unit 2.0 consolidates both into a single wall-mount device. This reduces wiring complexity at the door, lowers hardware cost per access point, and keeps the installation profile compact. The second-generation design brought improved RFID reading time and distance over its predecessor, and PoE 802.3af powering means no dedicated power supply is needed at the door frame. The inbuilt tamper switch provides an additional layer of physical security monitoring, and the 97 dB buzzer gives clear audible feedback for granted or denied access events. For integrators or end users sourcing this unit, it is available through Security Wholesalers as part of the broader Axis and 2N access control range. Note that this product is listed as discontinued; stock availability should be confirmed before project specification.
Buyer Decision Tips
Card Format Compatibility: The 02137-001 variant reads 125 kHz credentials only, specifically EM4x02 and HID Prox card types. If your site uses 13.56 MHz smart cards (such as MIFARE or MIFARE DESFire), or higher-security formats like HID iCLASS, this unit will not read them. Confirm existing card stock or intended credentials before specifying this reader.
Discontinued Product Status: This unit is listed as discontinued by the manufacturer. Before committing to a multi-door project using this model, confirm available stock quantity with your supplier to avoid mid-project supply gaps. For long-term scalability, assess whether a current-production Axis or 2N reader within the same ecosystem can serve as a replacement unit on subsequent doors.

Ideal Use Cases
Office Entry and Internal Secure Doors
The integrated controller-reader design suits individual office entry doors or internal controlled areas such as server rooms, where a compact unit keeps the door frame tidy and avoids a separate controller enclosure.
Sheltered Building Entry Points
IP54 and IK08 ratings allow installation at sheltered external doors, covered car park entries, and stairwell access points where rain splash, dust, and accidental contact from foot traffic are ongoing considerations.
Sites Running HID Prox Card Programmes
Organisations already operating HID Prox 125 kHz card programmes can add this unit to new doors without replacing existing credentials, as HID Prox is natively supported alongside EM4x02.
IT-Managed Access Control Networks
Web-based administration and network connectivity make this reader well suited to environments where IT teams manage user access centrally, review event logs, and issue credentials without visiting each door controller individually.
NFC-Enabled Smartphone Access Deployments
Where organisations want to issue mobile credentials to staff, the built-in NFC support allows compatible smartphones to open the door, reducing reliance on physical card stock and simplifying credential management for smaller teams.
Choosing the Right Model
- Choose this model if: Your site uses 125 kHz credentials in EM4x02 or HID Prox format, you need a single-device controller-reader for one or more doors, and PoE-based network installation is your preferred approach.
- Choose a different model if: Your site uses 13.56 MHz smart card formats such as MIFARE, MIFARE DESFire, or HID iCLASS, as this unit does not support those frequencies. If your project requires a large number of doors under central panel management rather than individual IP units per door, a centralised panel-based access control architecture may better suit the scale and cost structure. Also consider that this product is discontinued; a current-production reader in the same product family may offer better long-term parts and firmware support.
FAQs
- What card types does the 02137-001 variant read?
This specific variant of the 2N Access Unit 2.0 reads 125 kHz cards only, covering EM4x02 and HID Prox card formats. It does not read 13.56 MHz smart cards. If your site uses MIFARE, MIFARE DESFire, or HID iCLASS credentials, you will need a different reader that supports 13.56 MHz technology. - Can this unit be powered without a PoE switch?
Yes. While PoE 802.3af is the primary and most convenient power method, the unit also accepts 12 V DC as an alternative power source. This gives installers flexibility where a PoE switch is not available at the door location, though a separate 12 V power supply would then be required. - What loads can the relay outputs drive?
The active switch output supports 8-12 V DC at up to 600 mA, suitable for many electric strike mechanisms. The passive relay output uses NO/NC contacts rated up to 30 V / 1 A AC/DC, which covers a range of magnetic locks and electric bolts commonly used in commercial door hardware. - Is this reader suitable for an outdoor door?
It is rated IP54 for dust and water splash resistance and IK08 for impact resistance, making it suitable for sheltered outdoor entry points such as a covered building entrance, undercover car park door, or external stairwell. It is not recommended for fully exposed outdoor positions with direct rain contact, as IP54 does not cover water jets or immersion. - How is the unit administered and managed?
The 2N Access Unit 2.0 is managed through a web interface over the network, allowing administrators to add or remove users, configure access schedules, and review event logs without proprietary software installed locally. This suits IT-managed environments where network-based administration is the standard approach. - This product is listed as discontinued. Is it still worth purchasing?
Discontinued status means the manufacturer has stopped production, but existing stock may still be available for purchase. It can be a practical choice if your project is short-term or if you are adding a door to an existing installation already using this model for consistency. For new multi-door projects planned over several years, confirming stock depth and assessing current-production alternatives in the same 2N ecosystem is advisable. The 2N Access Unit 2.0 is available through Security Wholesalers, so stock availability can be confirmed directly with their team before project commitment.
Cabling Considerations
- Cable Type: Cat-5e or better is recommended by the manufacturer for the network/PoE connection to the unit.
- Maximum PoE Cable Run: Standard PoE maximum of 100 metres from the PoE switch to the unit applies per 802.3af specification. Keep cable runs within this limit to maintain reliable power delivery and network performance.
- Door Hardware Wiring: Use cabling rated for the load you are connecting. For the passive relay output (up to 30 V / 1 A AC/DC), standard 2-core security cable is typically sufficient for electric strikes and magnetic locks. Confirm cable rating against the specific lock hardware being used.
- Input Wiring: The 2 configurable inputs accept both passive and active mode connections, allowing door contact sensors and REX (request-to-exit) buttons to be wired directly to the unit. Use shielded cable in electrically noisy environments such as near lift motors or industrial equipment.
