HDMI over CAT5 HDBaseT Extender - 4K - 330 ft (100m)
StarTech ID: ST121HDBTPW
This HDBaseT extender Kit, extends HDMI up to 330 feet (100 Meters) over a single CAT5e or CAT6 cable. The
extender supports Ultra HD and Full HD resolutions (4K / 1080p) with support for 3D and the accompanying 7.1
digital audio. For added versatility, both the transmitter and receiver can be powered by the same single power
source using Power Over Cable (POC). The versatility of this video extender makes it an ideal solution for digital
signage applications in large buildings such as commercial shopping centers, stadiums, schools, and hospitals.
What is HDBaseT?
HDBaseT is a standardized, zero latency, video distribution 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 such as 100BaseT Ethernet, IR, RS-232 serial and power over cable.
Extend More than Video with HDBaseT
For greater versatility than a traditional HDMI extender or HDMI cabling alone, this HDBaseT extender offers
HDMI + Power Over Cable in a single kit. The added benefit of power over cable means you’ll only need one
power source at either side of your extension, great for extending to areas where power outlets may be limited.
Astonishing Picture Quality at 330 Feet Away
With the A/V industry quickly adopting 4K as the new high-resolution video standard, long range video
distribution can be a challenge with standard HDMI cables beginning signal degradation at 30 feet.
With HDBaseT you’ll be amazed at how Ultra HD picture quality, four times the resolution of high-definition
1080p can be maintained even at 330 feet away from your video source. Plus, because the extender supports
High-Definition 1080p and lower resolutions at 330, you can comfortably use this extender to make any video
source look great, while future proofing your setup for 4K implementation.

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,
