Astonishing Picture Quality at 295 Feet Away
With the A/V industry adopting 4K as its new high-resolution standard, long-range video distribution can be difficult, especially considering the 4K distance limitations on standard HDMI cables. You'll be amazed at how this HDBase-T extender kit can deliveryour 4K video signal at up to 295 ft. away from your video source.
The extender kit is also backward compatible with 1080p at 330 feet (100 m), so you can comfortably use it to make any video source look great.
Hassle-free, Professional Installation with a Single Cable
This extender has been specially crafted for a smooth, tidy setup. HDBaseT technology allows for single cable installation, for seamless integration using existing CAT5e or CAT6 infrastructure, avoiding the hassle of running multiple cables, while reducing potential failure points. Plus, the added benefit of power over cable means you'll only need one power source to power both your extender and receiver, great for extending to areas where power outlets may be limited. Mounting hardware is also included for both the extender and receiver for discrete, professional mounting.
