2N 01273-001 Verso Nickel Video Intercom Main Unit
The 2N 01273-001 Verso is a wired IP intercom main unit designed for secure access control, visitor verification, and two-way communication in multi-tenant residential, commercial, and healthcare environments. It integrates a 640 x 480 color camera with thermal infrared night vision, full-duplex audio, and PoE power delivery—eliminating separate power infrastructure and reducing deployment complexity.
Overview
This intercom operates as a standalone access verification hub or integrates with broader access control and VMS platforms via Ethernet. The combination of visible-spectrum video and thermal imaging enables reliable operator identification and verification around the clock. H.264 compression ensures efficient bandwidth use—important when deploying multiple intercoms on constrained networks or recording 24/7 without overrunning storage budgets. Power comes from a standard PoE connection (802.3af), so a single Cat5e or Cat6 run handles both data and power; no additional power supply cabinet or 12VDC lines required.
The nickel metallic finish suits modern architectural standards, making the unit visually appropriate in premium residential lobbies, commercial building entrances, and healthcare access points where aesthetics must align with function. The modular frame accepts two positions—one occupied by the main intercom, one available for future expansion modules—allowing phased upgrades without main unit replacement.
Key Features
- 640 x 480 Resolution Color Camera — Sufficient for facial identification and visitor screening at typical door-station distances (3–6 feet). Lower resolution than modern megapixel cameras, but paired with thermal imaging, it covers identity verification without excessive bandwidth overhead on aging network infrastructure.
- Thermal Infrared Night Vision — Built-in thermal imaging operates in complete darkness and low-light conditions without relying on white LED illumination. This is critical for late-night arrivals, emergency responders, and facilities where glare or privacy concerns rule out visible-spectrum IR LEDs.
- Full-Duplex Two-Way Audio — Voice communication flows simultaneously in both directions between the door station and a remote guard desk, apartment unit, or access control operator. Clear audio supports real-time verification and visitor instruction without awkward radio-style push-to-talk delays.
- H.264 Video Compression — Reduces storage footprint and bandwidth compared to uncompressed or motion-JPEG streams. For 24/7 recording across multiple intercoms, H.264 cuts storage requirements meaningfully—a concrete concern on premises with limited NVR capacity or older network uplinks.
- PoE (Power over Ethernet) — Draws under 15W, compatible with standard 802.3af PoE switches. No separate 12VDC power supply, no dedicated power conduit, no UPS branch—simplifies installation labor and reduces cabling clutter at the door frame.
- Modular Frame Design (2-Position) — One position holds the main intercom; the second is reserved for call buttons, card readers, or audio modules. Allows staged system expansion—add functionality later without ripping out the primary unit.
- Wired Connectivity — Ethernet connection ensures deterministic, low-latency communication ideal for access control and emergency use. No WiFi dropouts, no battery drain, no wireless security surface.
Integration and Compatibility
The 01273-001 communicates via standard IP protocols, making it compatible with most enterprise VMS platforms and access control systems that support IP cameras and SIP-based intercom endpoints. Consult your VMS documentation or system integrator to confirm codec and protocol support. The unit's PoE power model integrates seamlessly into managed PoE switches, provided your switch has sufficient power budget (typically 15W per port at full feature load).
When to Choose a Different Model
If your deployment requires higher resolution (e.g., 2MP or above) for long-distance facial recognition or forensic playback, evaluate higher-megapixel variants in the 2N Verso line. If your door station sits outdoors in rain or high-dust environments, verify IP rating requirements—confirm this unit meets your environmental protection threshold before final selection. If you need WiFi-only connectivity (hardwired Ethernet impossible), this wired intercom is not suitable; look for wireless intercom alternatives. For facilities with extensive legacy analog CCTV, consider a network video recorder to bridge analog-to-IP migration.
Typical Deployment Scenarios
- Residential Access Control: Multi-unit apartment or condominium lobbies where residents screen visitors before buzzing them in. Two-way audio and color video enable remote tenant interaction; thermal night vision supports secure late-night entry verification.
- Commercial Building Entry: Corporate office or medical facility main entrance. Security desk personnel use video and audio to confirm visitor identity, schedule, and purpose before granting access or calling a department contact.
- Healthcare Sensitive Areas: Restricted wards, pharmacy access, or laboratory entry. Thermal imaging does not emit visible light (no glare into patient rooms) while maintaining 24/7 verification capability.
- Gated Community Perimeter: Main gate or secondary checkpoint. PoE simplification means fewer outdoor power runs; thermal night vision covers overnight traffic flow and emergency vehicle verification.
Frequently Asked Questions
Q: Does the 2N 01273-001 support ONVIF?
A: Confirm ONVIF Profile compatibility with your VMS vendor or system integrator. The unit communicates via standard IP protocols; most enterprise systems support it, but verify codec and SIP intercom support in your specific VMS documentation before purchase.
Q: What is the maximum PoE power draw of the 01273-001?
A: The unit operates within the 15.4W budget of IEEE 802.3af PoE, meaning it is compatible with standard PoE switches without requiring PoE+ (802.3at) upgrades. Verify your switch has sufficient available power per port if you are deploying multiple intercoms on the same switch.
Q: Can I mount the 01273-001 outdoors?
A: Confirm IP rating and environmental specifications with the manufacturer datasheet. The nickel finish is corrosion-resistant, but outdoor exposure to direct rain, salt spray, or extreme temperature swings requires verification against your climate zone and site conditions.
Q: Does thermal night vision work through glass or plastic?
A: Thermal imaging is blocked by glass, plastic, or any transparent barrier. If the door station sits behind a protective window or vestibule, thermal imaging will not penetrate. Ensure the camera lens has unobstructed air exposure.
Q: What video formats does the 01273-001 support?
A: The unit compresses video in H.264 format, reducing storage footprint and bandwidth. Confirm H.264 codec support in your NVR or VMS before deployment.
Q: Is the frame truly expandable, and what modules are available?
A: The two-position frame allows future module installation. Consult the 2N product family for available modules (call buttons, card readers, etc.). At time of order, confirm which modules exist and match your integration roadmap.

The 2N 01273-001 represents a pragmatic approach to building access intercom—it bundles video, audio, and thermal imaging into a single PoE endpoint, cutting deployment labor and eliminating separate power infrastructure. The combination of 640 x 480 color video and thermal night vision is particularly valuable for 24/7 facilities: thermal imaging requires no visible-light LED (avoiding glare in patient corridors or residential lobbies) while maintaining reliable operator presence verification in complete darkness.
Technical Highlights:
- Thermal + Color Dual Imaging: Operators see both thermal and color channels simultaneously or switch between them—eliminates guesswork during low-light identity verification. Thermal is immune to visible-light spoofing (printed photos, masks) that can fool standard IR LED setups.
- H.264 Compression: Cuts recorded bandwidth to roughly 500 kbps–1.5 Mbps per stream depending on motion and complexity. For a 16-unit residential building recording 24/7, that is 8–24 Mbps aggregate—manageable on standard office networks and keeps storage footprint predictable.
- Sub-15W PoE Draw: Operates comfortably on standard 802.3af PoE switches (15.4W per port). No PoE+ upgrade required, no separate power cabinet, no UPS branch—meaningful cost and labor reduction on larger deployments.
Deployment Considerations:
- Resolution Limitation: 640 x 480 is tight for forensic facial recognition or long-distance identity verification (beyond ~6 feet). If your facility requires 24/7 perimeter surveillance with zoom-in capability for license plate or facial detail, evaluate higher-megapixel camera variants.
- Thermal Needs Unobstructed Lens: Glass or plastic barriers block thermal imaging completely. If the door station sits behind a protective window, thermal will not function—you lose half the night-vision capability. Plan for external (outdoor-exposed) lens mounting or consider alternative thermal-blocking designs.
- Modular Expansion Dependency: The second frame position is a future-proofing feature, but expansion modules must be confirmed as available and compatible before you commit to the 01273-001. Verify call button, card reader, or audio module availability with your integrator before final specification.
The 01273-001 is the right choice for multi-unit residential, healthcare, and mid-market commercial access control where aesthetics, PoE simplicity, and 24/7 thermal capability outweigh the need for megapixel resolution. Deploy it where door-station distance and operator workflow support sub-HD image quality—typically 3–8 feet from the lens to visitor face—and where thermal night vision eliminates the need for bright visible-spectrum LED illumination.
