The Extron WPD 110 A HDMI W IR is a specialized HDMI wallplate transmitter designed for professional audiovisual installations where clean cable management and discreet equipment placement are paramount. This unit functions as an integral part of a point-to-point HDMI extension system, transmitting high-definition audio and video signals from a local source over a single CatX cable—typically Category 5e, 6, or 6a—to a companion receiver unit located near a display. By converting the HDMI signal to a format suitable for long-distance transmission over twisted-pair cabling, this wallplate device enables installers to place source equipment such as media players, computers, or set-top boxes in a centralized equipment rack or closet, while sending the signal dozens of meters away to a wall or ceiling-mounted display without signal degradation.

A key feature of this model is its integrated infrared (IR) control pass-through capability. The "W IR" designation signifies that the wallplate includes an infrared receiver port, allowing it to accept commands from a standard IR remote control. It then embeds these IR codes into the signal being sent over the CatX cable to the remote receiver, which extracts and re-transmits them to the source device. This enables users to control hidden source equipment with a familiar remote from the viewing location, maintaining a user-friendly experience despite the physical separation of components. The wallplate design ensures a professional, finished appearance when installed in a standard electrical wall box or low-voltage mounting bracket, blending seamlessly into conference rooms, classrooms, or digital signage environments.

The device is engineered for reliability and supports high-resolution video formats, including Full HD 1080p/60, ensuring compatibility with common commercial displays. Its compact, all-metal construction is built for durability in high-use environments. Power for the transmitter is typically supplied remotely via the same CatX cable from the companion receiver, which is powered locally, simplifying installation by eliminating the need for a separate power outlet at the wallplate location. As a component within Extron's comprehensive HDXlink product family, the WPD 110 A provides a neat, robust, and functional solution for extending HDMI signals with integrated control, supporting streamlined AV system designs that are both powerful and aesthetically minimal.
