Product information

Description

The StarTech AV transmitter & receiver ST121HDBTPW extends HDMI signals up to 330 ft (100 m) over a single CAT5e or CAT6 cable using HDBaseT technology. It supports Ultra HD (up to 4096 x 2160) and Full HD (1080p) video, 3D and 7.1 digital audio. The kit includes both a transmitter and receiver and can supply power to the receiver via Power over Cable (POC), reducing the need for multiple power sources. The compact, black units include LAN (RJ-45) cables and power plugs for AU, EU, NA and UK, and are suitable for installations such as digital signage in commercial, education and healthcare environments.

Advantages

This HDBaseT extender transmits uncompressed HDMI audio and video with zero latency and extends distances far beyond standard HDMI cables while preserving 4K image quality. Single-cable installation over existing CAT5e/CAT6 infrastructure simplifies installation and reduces cabling complexity. Power over Cable capability lets the transmitter power the receiver from the same power source, and included mounting hardware supports tidy, professional installations. The unit is TAA compliant and comes with a 2-year manufacturer warranty and lifetime technical support.

Suitable for

Long-distance HDMI extension for digital signage
AV distribution in shopping centers, stadiums, schools and hospitals
Rooms or areas with limited power outlets
Professional AV installations requiring clean, single-cable runs

How to use

Connect the HDMI source to the transmitter unit and the display to the receiver unit. Run a single Cat5e or Cat6 cable between the transmitter and receiver RJ-45 ports, observing cable quality and length limits up to 100 m. Apply power to the transmitter (or receiver) using the supplied power adapter; if using Power over Cable, a single powered unit will supply both ends according to the kit instructions. Configure any required source or display settings (resolution, audio format) to match the capabilities of the connected devices.

Usage recommendations

For best performance, use high-quality Cat6 or Cat6a cable for runs approaching the maximum distance, keep cable runs away from high-voltage or noisy electrical equipment, and verify display and source HDMI settings to ensure 4K/60Hz or required audio formats are selected. Follow local mounting and safety guidelines when installing the units.
