Nortek Security & Control (NSC) has announced that its Gefen® brand is now shipping the 4K DisplayPort™ KVM Over IP Receiver unit (the EXT-DPKA-LANS-RX). This completes the launch of the all-new 12 model AV over IP line-up. The new line gives commercial integrators a full portfolio to extend and distribute 4K DisplayPort, USB, RS-232, IR, and 2-way audio over a Local Area Network.

“With the greatly expanded array of Gefen Gen 2.0 AV over IP products, we can now fully address the ever-growing needs of systems integrators,” Gefen Product Manager Jason Fitzgerald said today. “The new DisplayPort™ KVM Receiver follows suit with all other AV over IP Gen 2 products in the line by providing enhanced performance, new features, and expanded functionality.”

The EXT-DPKA-LANS-RX features a maximum output resolution of 4K 30 Hz 4:4:4. HDCP 2.2 and 1.4 are also supported. USB, RS-232 2-way IR, and audio can be routed independently between any Sender and Receiver unit, allowing end-users to control any of the sources and the displays within their network.

This Receiver features a built-in scaler to help optimise the image for a variety of displays and different viewing environments. It also includes a powerful video-wall controller that accommodates screen configurations up to 16×16, providing flexibility in sizing and manipulating live and signage content in demanding installations.

Digital and analogue audio break-out de-embeds audio from the video and sends it to a separate audio system, enhancing the impact of presentations.

The Receiver’s integrated USB hub with two USB 2.0 and two USB 1.1 ports accommodates touch panels, keyboard and mouse, and a variety of supported devices. This feature, along with analogue audio inputs and outputs, makes the new AV over IP products perfect to use in collaborative and interactive installations. To ensure maximum versatility and compatibility, the audio outputs on the Receiver units are compatible with both headphones and line level devices such as powered speakers.

The new KM Emulation feature facilitates real-time, simultaneous Keyboard and Mouse control of each source from connected workstations, eliminating the inherent limitations of earlier systems. Power-over-Ethernet allows the new Receiver unit to be powered through a standard PoE-enabled IP network switch, without the need for external power supplies.

When used with the EXT-CU-LAN Matrix Controller, system configuration is automated and quick. Enhanced network security by separating the control and AV networks is also made possible with the EXT-CU-LAN. The Enhanced Gefen® API provides added functionality and facilitates use with third-party controllers.

A built-in 2-port Gigabit switch allows daisy-chaining of additional Receivers. In applications where there is a need to replicate content on multiple displays, the ability to cascade Receivers extends the range of these units far beyond the limits of a point-to-point video distribution system.

“These products continue in the Gefen tradition of providing high performance, scalable, expandable, and secure AV routing and distribution solutions,” Fitzgerald concluded.

All Gefen Gen 2.0 AV over IP products have been specifically designed for use with the Gefen Syner-G™ software, available for download at For more information about the EXT-DPKA-LANS-RX and Gefen AV over IP line, please see and
