A complete extender kit that includes transmitterand receivers

This all-in-one extender kit saves you the complications and compatibility issues that can happen if you’re not using the correct receivers. It’s perfect for use in corporate environments such as small or large offices, or in retail, hospitality, and educational establishments.

Astonishing 4K picture quality from an impressive distance

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 video signal to three different locations while maintaining 4K Ultra HD picture quality. You get four times the resolution of high-definition 1080p, even at 115 feet (35 m) away from your video source.

The extender is also backward compatible with 1080p at 230 feet (70 m), so you can comfortably use it to make any video source look great.

Professional installation

HDBaseT technology offers a single-cable installation, so you can integrate this solution seamlessly using your existing CAT5e or CAT6 infrastructure. Plus, each device included with the HDBaseT extender kit is mountable, so you can keep the equipment out of sight in an equipment rack, or on a wall. This helps to reduce clutter and ensure a professional installation that doesn’t draw your viewers’ attention away from the content on your display. It’s perfect for customer-facing displays in bars or restaurants.

What is HDBaseT?

HDBaseT is a standardized, zero-latency video technology that’s revolutionizing HDMI distribution. HDBaseT uses an advanced method of modulation that enables you to distribute uncompressed HDMI audio and video, along with additional signals, over a single Ethernet cable.

Offering greater versatility than traditional HDMI extenders, and longer distances than HDMI cables alone, HDBaseT is the clear choice for every integrator and system designer. It can do so much, with just a single cable.

The ST124HDBT is backed by a 2-year StarTech.com warranty and free lifetime technical support.
