2N 02140-001 IP Verso 125 kHz RFID Intercom
The 2N 02140-001 is a wall-mounted access control intercom that merges 125 kHz proximity card authentication with IP-based voice communication. Built on the 2N IP Verso platform, it consolidates credential verification and two-way intercom into a single networked device, eliminating the need for separate card readers and call stations. Designed for multi-tenant buildings, corporate campuses, and secured facilities where visitor management and access logging must coexist.
Key Features
- 125 kHz RFID Reader: Proximity card and badge authentication. Standard frequency ensures compatibility with existing credential stock and minimizes re-issuance costs during migration.
- Dual RFID Support: 13.56 MHz and NFC alongside 125 kHz. Future-proofs credential roadmap without hardware replacement.
- PoE+ Power (802.3at): Single Ethernet cable supplies power and data. Eliminates aux power runs; integrates into standard IP infrastructure.
- Integrated Microphone & Speaker: Full duplex intercom audio without external handset. Enables real-time visitor screening before door release.
- Touch Numeric Keypad: PIN code entry for manual unlock or guest callback. Provides fallback when cards are forgotten or credential system offline.
- H.264 & MJPEG Video Streaming: Integrated camera (IP Verso platform) captures visitor images during calls. Logs tied to access events for audit trail.
- Compact Wall Mount (4.41 × 5.2 × 1.18 in): Low-profile installation at entry points without aesthetic interference.
- IP Network Connectivity: ONVIF-compliant streaming; centralized credential and call routing via 2N management platform.
Unlike discrete card readers bolted alongside a separate intercom speaker, the 02140-001 consolidates both functions into one device. When a resident or security staff member monitors a call, the card reader remains active — a visitor can present credentials, the system logs the read, and a decision to unlock is made from a single interface. This overlap eliminates workflow friction and ensures every entry attempt (card tap or PIN entry) is recorded alongside audio and video. Organizations deploying across 4-12 units per building see measurable reductions in call routing errors and credential-audit delays.
The 125 kHz choice matters for legacy environments. If your facility stock includes HID ProxCard or Salto ProximityCard legacy inventory, the 02140-001 reads them without intermediate converters. Retrofit scenarios — replacing old hardwired intercoms with IP-based systems — typically avoid credential re-issuance if the reader frequency matches. Dual 13.56 MHz / NFC support signals a forward path; new badge issuance can migrate to Mifare or NFC-enabled mobile credentials while the installed base of 125 kHz cards continues to function.
Integration anchors on ONVIF Profile S (streaming + SIP for call signaling) and proprietary 2N API for access control logic. The IP Verso platform works with Genetec Security Center, Milestone Xprotect, and Avigilon Control Center via ONVIF camera feeds; credential enrollment and door unlock commands route through 2N Door Control Module, which bridges to existing access control panels (Salto, Assa Abloy) or standalone relay outputs. PoE+ power keeps installation simple — no 24 VDC auxiliary feeds, no separate 12 V doorstrike supply lines. A single PoE+ switch port and one CAT6 to the reader, camera payload, and audio I/O are all supplied. Power budget is modest (~10-12 W sustained); even undersized PoE+ switches rarely experience congestion on a 4-8 unit deployment.
Consider the 02140-001 when visitor communication and credential logging must be inseparable. It's a better fit than parallel readers + intercoms for buildings with <50 access points and staff expecting real-time call + badge lookup integration. If your site runs a mature access control platform (Salto, Assa Abloy, Honeywell) with a separate video surveillance ecosystem, the 02140-001 adds intercom without forcing VMS dependency — just stream video to your NVR via ONVIF and route access events to your ACS via API bridge. Trade-off: the integrated camera is lower resolution than dedicated outdoor IR domes; don't expect 4K or 40 m IR range. For indoor entry vestibules and parking garage booths, the image quality is adequate.

In our experience fielding multi-building access control retrofits, the 02140-001 fills a specific gap that discrete products don't: the need to collapse card reader, intercom speaker, and video capture into one PoE-powered wall station without forcing a full ACS platform swap. We've deployed it across corporate office towers, residential buildings, and light industrial parks where the existing access control backbone (Salto, Assa Abloy, Honeywell) is mature and stable, but the intercom infrastructure is fragmented or end-of-life. The 125 kHz reader is the real anchor — it's the legacy frequency, and migrating credentials costs real money and operational headache. By choosing 02140-001 over a newer 13.56 MHz-only reader, you preserve credential investment for 5+ years while gaining modern IP video and centralized call routing. We've also seen integrators bundle the 02140-001 with a separate IP door controller (relay module) to unlock a mag lock or strike, decoupling the reader from hardwired relay logic. This flexibility is what separates it from integrated lock + reader combos that trap you into a single brand ecosystem.
Technical Highlights:
- 125 kHz + 13.56 MHz + NFC tri-band reader: Legacy cards continue to work unchanged; new installations can migrate to Mifare or NFC mobile credentials without hardware replacement. In a 200-unit office building, that's the difference between 0 vs. 200 re-card issuances during a platform upgrade.
- PoE+ (802.3at) single-cable power: Typical draw is 10–12 W sustained. One CAT6 run to the reader supplies camera, audio codec, and reader logic. Eliminates relay power supplies and hardwired 12 V doorstrike lines — significant cost and installation time savings on a 6–12 unit deployment.
- ONVIF Profile S + SIP intercom: Camera streams to any NVR; call signaling is standards-based SIP, not vendor lock-in. We've integrated the 02140-001 alongside Genetec, Milestone, and ExacqVision VMS instances on the same network without custom drivers or gateway appliances.
- H.264 video codec with MJPEG fallback: H.264 reduces bandwidth 40–50% vs. MJPEG on the same quality. Multi-codec support means older VMS platforms that don't parse H.265 still ingest video without transcoding overhead on the NVR.
- Integrated 2-way audio + PTZ call routing: Residents or security staff monitor the call station in real time; video timestamp and audio are tied to the credential event. If someone presents a card at 14:32, the system logs "Card XYZ read", captures the visitor image, and plays audio from that timestamp forward. Audit trail is automatic.
- Touch keypad fallback: If the card reader fails or credentials are forgotten, users can enter a PIN. Dual modality (card + PIN) means you don't lose operational access when the RFID frontend has a hiccup.
Deployment Considerations:
- 125 kHz read distance is typically 15–25 cm. Proximity cards must be presented at the reader face; thick leather wallets or card holders can reduce effective range. We've seen on-site training required where users expect smartphone-like "wave from 30 cm" behavior. Manage expectations in pre-deployment documentation.
- The integrated camera is standard IP Verso resolution — adequate for visitor identification in controlled indoor lighting, insufficient for outdoor perimeter or license-plate capture. Don't position the 02140-001 as a forensic camera; it's a visitor presence capture tool.
- SIP call routing requires 2N management software or a compatible SIP PBX. If your site uses analog phones or a legacy intercom system (not SIP-aware), you'll need a SIP gateway or bridge appliance. Budget that integration cost upfront.
- PoE+ switch ports are required — standard 802.3af (15 W budget) will not sustain the 02140-001 and downstream relay modules. Verify PoE+ availability on your network closet before installation.
- The unit is rated for wall mount only — no pole-mount or outdoor enclosure option. It's an indoor entry-point fixture. Outdoor vestibule installations require weather protection (awning, covered portico).
- Credential enrollment (adding new cards) happens via 2N software or mobile app, not on-device. You'll need network access to the 2N management backend. Offline card enrollment is not supported.
The 02140-001 is the right choice for integrators managing mid-scale access + intercom unification across corporate and multi-tenant buildings where legacy 125 kHz credential stock is in place and IP-video integration is expected. If you're seeing end-of-life analog intercoms pair with separate card readers, and the ACS platform is stable, the 02140-001 collapses that siloed architecture.
