Power Over Cable, Supports CAT5e(50M) / CAT6(40M) Ethernet Cable

The ST121SHD50 HDMI® over Cat5e/Cat6 Video Extender kit lets you extend HDMI video and audio by up to 165 feet (50 Meters) over dual Cat5e cables or dual Cat6 cables. For added versatility the kit features Power Over Cable and only requires a single power adapter that can be connected to either the Transmitter or Receiver.

With support for High-Definition resolutions of up to 1920x1080 / 1080p and the accompanying digital audio, this cost-effective HD extender can easily be installed using new or existing Ethernet infrastructure wiring. For a convenient plug-and-play installation, the HDMI extender features built-in EDID monitor emulation, which ensures native resolution and maximum compatibility with your display or projector.

For added flexibility and convenience, HDMI cables up to 32ft (10m) can be connected to both the local and remote units, which lets you extend your HDMI signal to even further distances.

The HDMI extender kit offers a point-to-point digital signage solution right out of the box, including both local transmitter and remote receiver units, along with optional hardware that lets you mount the units as needed. Plus, with Power Over Cable, you can easily extend an HDMI signal in areas where access to power outlets is limited.

Backed by a 2-year warranty and free lifetime technical support.

RoHS compliance The Restriction of Hazardous Substances (RoHS) Directive aims to restrict certain dangerous substances commonly used in electrical and electronic equipment. Any RoHS compliant product is tested for the presence of Lead (Pb), Cadmium (Cd), Mercury (Hg), Hexavalent chromium (Hex-Cr), Polybrominated biphenyls (PBB), and Polybrominated diphenyl ethers (PBDE). PBB and PBDE are flame retardants used in several plastics. For Cadmium and Hexavalent chromium, there must be less than 0.01% of the substance by weight at raw homogeneous materials level. For Lead, PBB, and PBDE, there must be no more than 0.1% of the material, when calculated by weight at raw homogeneous materials. Any RoHS compliant component must have 100 ppm or less of mercury and the mercury must not have been intentionally added to the component. In the EU, some military and medical equipment are exempt from RoHS compliance.
