StarTech.com HDMI Over IP Extender Kit - Video Over IP Extender with Support for Video Wall - 4K
This HDMI® over IP extender gives you the flexibility to locate digital signage displays where you need them. Using your local network to extend a 4K HDMI signal, you can seamlessly distribute video to multiple displays from multiple source devices, making it easy to position your displays, or create a video wall.

You can add additional receivers (sold separately) to distribute your HDMI signal to multiple locations. You can also create a video wall and combine your video source across multiple displays.

The IP receiver also features RS-232 extension which enables you to add a remote serial-operated device.

Versatile configuration options

In a point-to-multipoint setup, you can connect the HDMI over IP kit through a Gigabit LAN portal. You can also connect one or several sources (transmitters) to multiple displays (receivers) over your network, using a Gigabit Ethernet switch with IGMP.

For further scalability, you can combine up to 16 total extender kits. 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.

For smaller-scale applications, you can use the extender kit as a point-to-point video extender by connecting the transmitter and receiver units directly over Cat5 or Cat6 cabling up to 330 feet (100 meters). In this configuration, two independent 3.5 mm audio source can also be extended to separate 3.5 mm speaker systems.

Ultra HD 4K resolution at 30Hz

This HDMI over IP kit delivers astonishing 4K UHD video to your remote 4K displays. 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 distribution throughout large buildings such as schools, hospitals, shopping centers or areas. The extender also works at lower resolutions such as 1080p or 720p.

Manage your video distribution from your mobile device

This HDMI distribution kit features an easy-to-use video control software app to 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 create and manage a video wall, for an impressive digital signage presentation.

The software is available on iOS for your iPhone or iPad, and Android™ for your smartphone or tablet.

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 cable, it eliminates both the expense and hassle of running specialized cables.
