The BG-DA-1X4C50M is a 4-way HDMI splitter/extender kit. It features a single HDMI input which is split to 4 RJ45 outputs that are capable of extending the HDMI signal up to 50 meters (165 feet) away via the included receiver units. Lobbies, warehouses, offices, and sports bars are just a handful of the many situations this kit is perfect for. This unit will distribute signal to your displays for a fraction of the cost vs. using standard HDMI cabling. Category cable is cheaper, easier to install, and carries signal further than is possible with HDMI, making the BG-DA-1X4C50M an easy choice for your system.
