Our Discovery Series offers a cost-effective 4K extension with flexible USB and HDMI capabilities for software video conferencing and audio extraction. These kits were designed specifically to address signal extension for multiple participants in classrooms, huddle spaces, or conference rooms. The Discovery series includes an HDBaseT Wall Plate Transmitter, and Receiver kit that pairs natively with soft-codec video conferencing applications such as Zoom, Teams, Skype, WebEx and more.

With both US and UK transmitter wallplate options available, Discovery makes collaboration easy and fluid with support for resolutions up to 4K.

The transmitter allows you to automate the display power ON by using pre-loaded RS232 commands whenever a video signal is introduced to the  system. It will also turn the display power OFF after a specified amount of time has passed when no video signal is present. It gives you the ability to turn the display ON or OFF as well and switch from one input to another
manually using the control buttons on the transmitter panel. This product is ideal for situations where USB must be extended alongside HDMI for display interactivity for items such as interactive whiteboards or projectors.
