Comelit UMV2S Ultra Video Surface Kit 2-Wire 2-Button
Overview
The Comelit UMV2S is a surface-mount video intercom unit designed for 2-wire infrastructure retrofits and new-build access control systems. It combines a 4MP video sensor with two integrated control buttons, powered entirely by PoE+ (802.3at)—eliminating the need for separate power drops at each entry point. This is the right choice if you're retrofitting legacy 2-wire systems or building multi-unit residential or commercial installations where simplified cabling reduces labor and materials cost.
Compatibility
The UMV2S integrates with Comelit video door entry and access control platforms. It operates on PoE+ (802.3at) power, meaning any standard 802.3at-capable PoE switch will support it without dedicated power wiring. The unit is designed for deployment in multi-unit residential, commercial, and institutional environments where standardized video intercom ecosystems are already in place. Confirm your existing Comelit control panel or VMS supports the UMV2S model before ordering—compatibility is family-specific, not universal across all access control brands.
Installation Notes
Surface-mount installation requires a standard wall or door-frame prep surface. The PoE+ injector or switch port must deliver full 802.3at power (minimum 15.4W) to avoid power starvation during video transmission and button operation. Run CAT5e or better twisted-pair cabling to the unit; while 2-wire legacy systems are supported, modern IP-based deployments use standard Ethernet runs. Verify cabling distance and switch port power availability before installation to prevent intermittent resets or video dropout under peak load.
