Description
This item is brand-new, factory sealed.
Deploy HDMI over LAN and get a video over IP solution that's scalable and features intuitive control that's ideal for your video wall or other digital signage application. 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. This makes it easy to position your displays, or create a video wall, for maximum audience impact
You can add (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 at your video source or at 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 presentation.
Versatile configuration options
In a point-to-multipoint setup, you can connect the HDMI over IP kit through an unmanaged or managed 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 (also requires a Gigabit Ethernet switch with IGMP).
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 for a one-to-one HDMI extension up to 330 feet (100 meters). In this configuration, a separate 3.5 mm audio source can also be extended to a separate 3.5 mm speaker system.
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 that's sure to catch your audience's attention.
The software is available on iOS for your iPhone or iPad, Android™ for your smartphone or tablet, and Google Chrome™ 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.
