Real World Applications


When managing content in high-security environments, creating a safe and secure control room is critical. In the vast majority of such applications, that requires routing signals from a server room, where the computers are safely stored, to a control room, where approved personnel access the data and video feeds. Whether that's in a security surveillance center, an operations control room or some other security-related environment, being able to extend video, audio and USB is a must.

The DPX-XT-4P provides system architects with the flexibility they need to create secure environments for servers as well as the end users accessing those computers. And with quad DisplayPort signal extension, users can manage their connected computers with expanded display options, enabling them to stay in control of their content at all times.

Digital Signage

Managing a multi-screen digital signage solution requires some important foresight regarding the signal path to those informative and attractive displays. Particularly when it comes to properly scheduled, updated and managed content being displayed, it's much more efficient to keep all of the digital signage hardware in one central location and to extend the video signals out from there.

That means signal extension is an important part of a smart digital signage solution, and the DPX-XT-4P gives users the flexibility they want and need to place their digital signage screens in the right locations to maximize their effectiveness.

Audio and Visual Recording

For users in the recording arts, maintaining the utmost in signal and recording fidelity is an absolute necessity. For video recording, it is often important that no unsightly computers are visible. Similarly, audio engineers must keep noisy computers away from the rooms where recording happens to ensure the final product sounds professional. In both such instances, the DPX-XT-4P gives users the ideal way to keep their servers or computers away from areas that audio or video recording is being done, ensuring a better final product.
