Bought a pair of AGPtek for HDMI extenders through LAN routers and they worked great. My place of worship needed to feed a camera into a second room when space was tight and there was only one wired network to work with. We plugged them in, no setup no setup, it just worked and streamed both audio and video seamlessly over a standard existing wired router network like most homes and small businesses do. Make sure you're using CAT6 network cables and good HDMI connections and you're good to go.
