Description

StarTech ST121HDBTE HDMI Extender Over Cat6

Overview

The StarTech ST121HDBTE is an HDMI extender designed to transmit high-definition video and audio signals up to 230 feet (70 meters) over a single, standard Cat 5e or Cat 6 Ethernet cable. This unit is ideal for extending HDMI displays in environments where running a direct HDMI cable is impractical or cost-prohibitive, such as large conference rooms, auditoriums, or digital signage deployments. The ST121HDBTE supports Power over Cable (PoC) functionality, meaning only one of the units (either transmitter or receiver) requires a power connection, simplifying installation. It supports resolutions up to 4K @ 30 Hz at shorter distances (35m) and 1080p @ 60 Hz at its maximum range (70m).

Compatibility

This extender is compatible with standard Cat 5e UTP or better cabling. It supports a wide range of digital resolutions including 3840x2160, 2560x1600, 1920x1200, 1920x1080, and 1280x720. It also passes 7.1 surround sound audio. The input and output connectors are 1x HDMI and 1x RJ-45 on both the transmitter and receiver units. It requires a separate power adapter (included) for one of the units, drawing a maximum of 7 Watts.

Installation Notes

The operating temperature range is 0C to 40C (32F to 104F), with storage temperatures between -10C to 60C (14F to 140F). The unit requires 100-240V AC input and outputs 12V DC at 1.5A. The physical dimensions of each unit are 8.0 cm (length) x 6.7 cm (width) x 2.5 cm (height), with a weight of 428.0 g.
