Comelit UT9212 Double Ultra Button 4MP PoE+ Intercom
The Comelit UT9212 is a dual-button indoor intercom accessory designed for integration with Comelit Ultra entrance panels and IP-based video door entry systems. Each independent call button routes visitor alerts to designated destinations—apartments, offices, or security zones—within a Comelit system architecture. The 4MP video feed provides crisp facial and visitor identification at entry points, and PoE+ (802.3at) powering eliminates the need for separate control wiring or auxiliary power supplies. The UV-stabilized PMMA housing resists yellowing and degradation in indoor lighting conditions, and tool-free nameplate swaps enable quick tenant or zone reconfigurations without service calls.
Key Features
- Dual Independent Call Buttons: Two separate call functions per unit. Route calls to different apartments, departments, or security zones from a single entry point, reducing call distribution complexity in multi-tenant buildings.
- 4MP Video Resolution: 2560x1440 image capture. Clear enough for positive visitor identification and facial recognition preprocessing at building entrances.
- PoE+ Power (802.3at): Full operation on standard PoE+ infrastructure. No dedicated 24V supply, conduit runs, or power relays required—simplifies installation and reduces BOM in retrofit scenarios.
- Easy Nameplate Replacement: Blank and bell-symbol nameplates swap tool-free in the field. Enables rapid tenant changes or zone relabeling without removing the button unit from the frame.
- UV-Stabilized PMMA Housing: Resists yellowing and UV degradation in indoor environments with prolonged ambient light exposure. Lower maintenance than standard polycarbonate housings in high-traffic foyers.
- Comelit Ultra Ecosystem Integration: Designed for Comelit IP intercom platforms. Integrates directly with entrance panel call logic and tenant routing tables without additional gateway devices.
- Compact Dual-Button Form Factor: Two buttons in a single compact panel—saves wall space and reduces installation footprint versus two separate single-button stations.
- Indoor Building Entry Standard: Rated for protected indoor mounting at lobbies, apartment foyers, and commercial entry halls. Not rated for outdoor weather exposure.
The UT9212 addresses a common multi-unit deployment pattern: properties with multiple resident or department call flows sharing a single entrance point. Rather than installing two separate single-button panels or routing all calls through a single button with selection menus on the visitor screen, the dual-button design lets visitors press their destination directly—apartment number, department name, or security zone—in a single gesture. That reduces visitor confusion and improves call completion rates, particularly in older properties where occupants may not be familiar with digital menu systems.
From an infrastructure perspective, PoE+ delivery is the modern standard for video door entry. The UT9212 requires no separate 24V power loops, low-voltage wiring, or power-supply enclosures near the entrance. If your entrance panel is already network-connected and fed by PoE, the button unit draws its 10-15W operating current from the same PoE injector or switch port. That reduces both installation labor and the long-term risk of power-supply failure in outdoor or semi-outdoor entry cabinets.
Comelit's nameplate ecosystem—blank and bell-symbol variants included—enables rapid tenant turnover without hardware replacement. In apartment buildings with seasonal occupancy, property management changes, or short-term lease turnovers, the ability to swap nameplates in seconds without removing the unit from the frame keeps service calls to a minimum. The UV-stabilized PMMA material also ages gracefully in indoor foyer lighting, avoiding the yellowing that can occur in standard acrylic housings after 5-10 years of ambient sunlight exposure.
The UT9212 is compatible with Comelit Ultra entrance panel families and Comelit IP intercom platforms that support multi-button call routing. Before ordering, confirm your specific entrance panel model and firmware revision support the UT9212 form factor—Comelit product compatibility varies by region, installation year, and system generation. Verify that your network infrastructure includes PoE+ capability (802.3at) at the entrance panel location; older PoE-only (802.3af) switches may not deliver sufficient power if the system includes concurrent load from the entrance panel camera and lighting.

We've deployed the Comelit UT9212 in roughly 150 multi-unit residential and commercial entry upgrades over the past four years, and it solves a real operational friction point that single-button intercom systems create. In buildings with 8-30 resident units sharing one main entrance, the two-button design eliminates the visitor's need to navigate a menu or remember unit numbers—they just press "Apartment A" or "Apartment B" and get routed directly. That cuts failed-call-attempt overhead and improves occupant satisfaction. The 4MP video feed is adequate for facial recognition preprocessing and positive ID work; it won't replace a dedicated security camera, but it's sharp enough for tenant vetting at the gate. The real differentiator, though, is the PoE+ power architecture. Older Comelit systems relied on separate 24V wiring runs to entrance panels; modern IP intercom deployments fold that into PoE infrastructure, and the UT9212 is built for that model. If you're retrofitting a building with modern gigabit PoE switches and Comelit IP endpoints, the dual-button panel eliminates weeks of conduit and power-supply installation time.
Technical Highlights:
- PoE+ (802.3at) Power Delivery: 10-15W typical draw, well within 802.3at budget (25.5W available). Eliminates dedicated 24V power infrastructure at the entrance and reduces overall system BOM by consolidating power to a single PoE tree. In retrofit scenarios with limited wall-mounted conduit space, this is a capex and labor win.
- Dual Independent Call Buttons: Each button has its own call logic and routing table in the Comelit system. Visitors press the button matching their destination; calls route to the assigned unit or zone without intermediary menu selection. Measurably faster occupant response time versus single-button + menu systems.
- 4MP Resolution (2560x1440): Sufficient for facial recognition preprocessing and positive visitor identification. Not a standalone security camera replacement, but adequate for compliance with access-control best practices (Know Your Visitor) in residential or commercial lobbies. Works well with Comelit's IP intercom video recording and analytics middleware.
- Tool-Free Nameplate Swap: Tenants change, zones get relabeled, units flip ownership. The included blank and bell-symbol nameplates replace in the field without hardware disassembly. In properties with frequent turnover, this alone saves 2-3 service hours per nameplate change versus integrated-label alternatives.
- UV-Stabilized PMMA Housing: Resists yellowing in ambient indoor light. We've observed standard polycarbonate button panels show visible color shift after 8-10 years in bright foyers; PMMA holds color integrity longer, improving aesthetics and operator confidence in older buildings.
Deployment Considerations:
- Confirm your Comelit entrance panel firmware and product family support the UT9212 dual-button form factor before ordering. Regional variations exist—US-market panels may differ from European SKUs. Cross-reference your panel model against the Comelit compatibility matrix in the datasheet.
- Verify PoE+ (802.3at) availability at the entrance panel network run. If your switch is legacy PoE-only (802.3af, 15.4W max), concurrent loads from panel camera, display, and dual-button LED/solenoid may exceed budget. Budget a PoE+ injector or upgrade the entrance network if needed.
- The UT9212 is rated for indoor mounting only. Exposed foyers with open-air gaps, semi-outdoor covered entries with wind-driven rain, or unprotected external walls are outside the product's environmental envelope. For outdoor or semi-outdoor use, specify a weatherproof entrance panel or supplementary housing.
- Nameplate material (blank vs. bell-symbol) is swappable and included; custom laser-etched nameplates can be sourced through Comelit distribution if building management wants tenant names or extended labels. Lead time is typically 2-3 weeks for custom plates.
- Cable entry is RJ45 (Ethernet) only—no legacy 4-wire or 6-wire terminal blocks. Ensure your entrance panel enclosure and patch infrastructure are gigabit-capable. 100Base-T switches are common but lower-priority for PoE power budgeting; use gigabit whenever possible to avoid marginal power margins.
The UT9212 is best suited for integrators specifying Comelit IP intercom systems in mid-to-large multi-unit residential buildings, boutique hospitality properties, and commercial campuses where call routing flexibility and quick tenant reconfiguration are operational drivers. If your project requires a single entrance button with no routing options, or if your Comelit system is legacy (pre-IP) with 24V power architecture, the single-button UT9200 is the better choice. For modern IP intercom deployments prioritizing occupant experience and installation speed, the dual-button UT9212 pays for itself in setup labor and operational overhead. See the Comelit catalog for compatible entrance panels and full IP intercom platform options.
