This 4K HDMIÂ® over IP receiver works with the 4K HDMI over IP Extender Kit (sold separately) and lets you extend a 4K HDMI signal, as well as RS-232 peripheral device connections, over your network. You can use additional receivers (sold separately) to distribute the HDMI signal to multiple locations, each with 4K support, and combine your remote displays to create a video wall. The IP receiver also features RS-232 extension which enables you to add a remote serial operated device at your video source or each remote display. This HDMI over IP extender is the perfect solution for combining a serial-operated touchscreen with your display or video wall, to create interactive digital signage presentations. Extended scalability You can add multiple receivers to your HDMI over IP extender kit to create a point-to-multipoint setup or video wall. In these configurations, you can also add additional sources (transmitters) with even more displays (receivers) over your Gigabit Ethernet switch with IGMP. For further scalability, you can combine up to 16 total (transmitters) and as many receivers (displays) as your network bandwidth can support. The extender also features a separate 3.5 mm audio source that enables you to switch between the native HDMI audio and a separate 3.5 mm audio source, so you can distribute a single audio source to multiple remote locations over IP (also requires a Gigabit Ethernet switch with IGMP). Ultra HD 4K resolution at 60Hz This HDMI over IP kit uses H.264 compression to deliver astonishing 4K UHD video to your remote 4K displays over an IP connection. With support for 4K, you can achieve an output resolution of up to 3840 x 2160p at 30Hz, which enables you to extend a 4K video source to multiple remote locations -- perfect for digital signage or entertainment video distribution throughout large buildings such as schools, hospitals, shopping centers or areas. The extender is backward compatible with lower resolutions such as 1080p or 720p, making it great for lower resolution applications while future-proofing your infrastructure for 4K implementation. Manage your video distribution from your mobile device This HDMI distribution kit features an easy-to-use video control software app that helps you manage your IP video distribution. The app is simple to set up, with automatic hardware detection, and it lets you switch video sources for each remote display. You can also create and manage a video wall, for an impressive digital signage presentation thatâ€™s sure to catch your audienceâ€™s attention. The software is available on iOS for your iPhone or iPad, Androidâ„¢ for your smartphone or tablet, and Google Chromeâ„¢ browser. Professional, cost-effective, simple installation The HDMI over IP extender kit includes optional slot shelf mounting hardware for a tidy installation. Plus, because the extender uses standard non-proprietary CAT5e or CAT6 Ethernet cable with RJ-45 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.
