StarTech.com HDMI Video Over IP Gigabit Ethernet Extender Kit - 1080p HDMI Extender over Cat6 LAN Ethernet - up to 330 feet (100 meters) (ST12MHDLAN) - video/audio extender - 1GbE, HDMI

Deploy content for digital signage through a scalable distribution system with intuitive control that's ideal for point-to-point or video wall applications. The HDMI over IP kit lets you extend an HDMI signal over your network. You can use additional receivers (sold separately) to distribute the HDMI signal to multiple locations and combine your remote displays to create a video wall.
In a point-to-multipoint setup, the HDMI over IP kit can be connected through an unmanaged or managed Gigabit LAN portal. You can connect one or multiple sources (transmitters) to multiple displays (receivers) over IP, using a managed Gigabit Ethernet switch (with IGMP). For additional scalability, you can combine up to 16 different kits.
For smaller-scale applications, the extender kit can be used as a point-to-point video extender. You can connect the transmitter and receiver units directly over Cat5 or Cat6 cabling for a small-scale, one-to-one HDMI extension up to 330 feet (100 meters).
The HDMI distribution kit features easy-to-use video control software that helps you manage your IP video distribution. The app is simple to set up with automatic hardware detection, and lets you switch video sources for each remote display. You can also intuitively create and manage a video wall for an impressive digital signage presentation to catch the attention of your audience.
The software is available on iOS for your iPhone or iPad, Android for your smartphone or tablet, and Google Chrome browser.
The HDMI over IP extender kit includes optional mounting hardware for a tidy installation. Ideal for high-definition applications, the extender supports 1080p video resolutions and digital stereo audio. Plus, because the extender uses standard non-proprietary Cat5e or Cat6 Ethernet cable with RJ45 connectors, it eliminates both the expense and hassle of running specialized cables.The extender also features an EDID copy function, which ensures native resolution and maximum compatibility with your display or projector for a convenient plug-and-play installation.
NOTE: Your router must support IGMP snooping. Please refer to your network switch or router documentation to ensure IGMP snooping is supported and enabled.
