Comelit UMV6S 2-Wire Video Surface Kit
Overview
The Comelit UMV6S is a 2-wire video surface unit designed for intercom and access control integration in retrofit and new-build deployments. This 6-button configuration delivers 4MP video resolution over PoE+ (802.3at) power, eliminating the need for dedicated power wiring at the surface. The 2-wire topology simplifies installation in existing buildings where infrastructure is already in place, and PoE+ support ensures reliable operation across standard network environments and extended cable runs.
Key Features
- 4MP Video Resolution: Delivers sufficient detail for facial identification and license plate capture at typical entrance distances—meaning you can read expressions and verify credentials without throwing oversized storage at the recorder.
- PoE+ (802.3at) Power: Single network cable carries both video/audio and power to the surface unit. No 24VAC or 12VDC supply needed at the mount location—reduces panel clutter and eliminates a separate power failure point in the field.
- 2-Wire Architecture: Designed to work over existing 2-wire intercom cabling (if present) or standard Cat5e/Cat6 network runs. This is a real advantage in retrofit scenarios where pulling new power drops is expensive or disruptive; it keeps installation time and cost down compared to analog 2-wire systems requiring separate video capture.
- 6-Button Configuration: Physical button array supports direct access to common functions—door unlock, call routing, call cancellation—without relying solely on touchscreen or mobile controls. Tactile buttons are faster for high-traffic entrances and work in gloved conditions.
- ONVIF Compatibility: Integrates with ONVIF-compliant video management platforms and network video recorders, reducing vendor lock-in and simplifying system architecture if you're mixing brands downstream.
- Audio Capability: Full two-way audio over the same network link. No separate intercom wiring—the surface unit handles voice and video bidirectionally, simplifying commissioning and troubleshooting.
Integration & Compatibility
The UMV6S pairs with Comelit video intercom systems as a primary integration target. Its ONVIF Profile support means it can also be deployed in multi-vendor environments using standard SIP or RTSP for call signaling and streaming. For network infrastructure planning, confirm your PoE+ switch or injector can deliver 802.3at power; the unit draws power efficiently, so it won't strain a well-sized switch. If your network backbone uses VLANs or firewall rules, plan for video streaming ports (typically RTSP 554 or 8554) and SIP/H.323 signaling ranges on your access control or intercom controller.
When to Choose a Different Model
If you need higher resolution (8MP or above) for distant or wide-angle scenarios, consider a higher-megapixel variant in the same family. If your deployment is indoors only and you don't require the 2-wire benefit, a standard IP surface with more button options may be simpler. If you need IP66 or IP67 environmental rating for outdoor rain exposure, verify the UMV6S rating against your site conditions—this unit is designed for covered entry vestibules or interior installations.
Frequently Asked Questions
Q: Does the UMV6S work with existing analog 2-wire intercom cabling?
A: The UMV6S is designed for 2-wire topology, but confirm cable gauge and run length with your Comelit integrator. Existing copper 2-wire may work for power and signaling if runs are under 100 meters; longer runs should use Cat5e/Cat6 to ensure reliable PoE+ delivery.
Q: What video management systems can record from the UMV6S?
A: Any ONVIF-compliant NVR or VMS platform that supports RTSP streaming and SIP/H.323 call signaling can integrate the UMV6S. Comelit systems are primary, but verify your existing platform's ONVIF support before purchase.
Q: Does the UMV6S require a dedicated PoE+ switch, or can a standard PoE switch work?
A: The UMV6S requires PoE+ (802.3at, minimum 30W per port). Standard PoE (802.3af, 15.4W) will not deliver sufficient power. Use a PoE+ injector or switch rated for 802.3at to ensure stable operation.
Q: Can I use the UMV6S outdoors?
A: The UMV6S is not rated for direct rain or submersion. Deploy it in covered entry vestibules, under architectural overhangs, or interior hallways. If you need outdoor weather protection, verify the IP/IK ratings against your exposure before ordering.
Q: What's the maximum cable run from a PoE+ switch to the UMV6S?
A: PoE+ can reliably power devices up to 100 meters (328 feet) on Cat5e or better. Beyond that distance, use a midspan injector closer to the surface unit or upgrade to PoE++ (802.3bt) if available on your network infrastructure.

The UMV6S hits a specific niche: retrofit intercom installations where 2-wire infrastructure already exists or where running dedicated power is impractical. At 4MP over PoE+, you're getting usable detail—facial recognition-grade resolution—without the power and cabling overhead of higher megapixel variants. The real win here is simplicity: one cable, one power source, and ONVIF compliance means you're not locked into a Comelit recorder if your architecture calls for a different backend.
Technical Highlights:
- 4MP Resolution (2688 x 1520 or equivalent): Adequate for entrance verification and credential reading at typical doorway distances. You'll see facial detail clearly enough to match against ID photo databases or live visitor lists without wasting storage on 8MP overhead.
- PoE+ (802.3at) Power Delivery: Single network cable eliminates the need for 24VAC transformers or 12VDC supplies at the surface mount. This reduces field wiring, cuts down on power failures, and simplifies troubleshooting—if video is live, power is present.
- 2-Wire Topology Support: For buildings with existing 2-wire analog intercom drops, the UMV6S can leverage that infrastructure if cable condition and distance permit. For new installations, standard Cat5e/Cat6 is preferred. Either way, you're avoiding the cost and disruption of running separate power and video conduits.
Deployment Considerations:
- Confirm your PoE+ switch or injector is rated for 802.3at (minimum 30W per port). Standard 802.3af PoE will starve the unit and cause intermittent resets.
- The UMV6S is not outdoor-rated for direct rain. Deploy it in vestibules, covered entries, or interior hallways. If you need weather protection, this is not the right model.
- ONVIF compliance is genuine, but verify your downstream VMS or NVR explicitly supports RTSP video streaming and SIP/H.323 signaling before commissioning. Comelit systems are the primary target, but don't assume third-party platforms will auto-discover the device.
Position the UMV6S for corporate or institutional retrofit projects where intercom modernization is driven by aesthetics or feature upgrade (adding video to an existing 2-wire system) rather than a rip-and-replace network overhaul. In new office or light commercial builds where you're choosing the cabling standard, a standard PoE-only surface with more button options may be simpler—you don't need the 2-wire fallback.
