StarTech ST121WHDLR Wireless HDMI Extender Kit
Overview
The StarTech ST121WHDLR is a wireless HDMI extender kit designed to transmit uncompressed 1080p video and audio signals up to 656 feet (200 meters) over a 5GHz frequency band. This eliminates the need for long, cumbersome HDMI cables, making it ideal for digital signage, conference rooms, or any scenario where running physical cables is impractical or aesthetically undesirable. The kit includes both a local transmitter and a remote receiver unit, simplifying deployment.
Compatibility
This kit supports a maximum resolution of 1920 x 1080 @ 60Hz (1080p) and is backward compatible with lower resolutions including 1080i, 720p, 480p, and various VGA/SVGA/XGA/SXGA formats. It is designed for point-to-point transmission and is not intended for multi-device or network-based distribution. The included AC adapters provide 5V DC at 2A to power each unit.
Installation Notes
The operating temperature range for both units is 0°C to 40°C (32°F to 104°F), with storage temperatures from -20°C to 80°C (-4°F to 176°F). Humidity should be kept between 25% and 60%. Each unit measures 4.3 inches (11.0 cm) in length, 2.5 inches (6.4 cm) in width, and 1.0 inch (2.5 cm) in height, weighing 8.3 oz (236.0 g).
