The StarTech ST121SHD50 HDMI over Cat 5e/Cat 6 Video Extender Kit makes it easy to extend your HDMI audio and video by up to 130' over dual Cat 5e cables, or up to 165' over dual Cat 6 cables. For added convenience and flexibility, this kit lets you connect HDMI cables up to 32' to both local and remote units, which lets you extend your HDMI signal even further. Sweetwater understands you may want to extend an HDMI signal into areas with limited power outlet access. No worries. Courtesy of Power Over Cable technology, the kit requires just a single power adapter that you can connect to either Transmitter or Receiver, both of which are included.
