The StarTech ST121HDBTL is an HDBaseT extender kit designed to transmit a 4K HDMI signal up to 70 meters (230 feet) over a single Cat 5e or Cat 6 Ethernet cable. This unit is ideal for extending high-definition video and audio from a source device, such as a media player or computer, to a remote display in environments like digital signage, conference rooms, or control centers where running a long HDMI cable is impractical. It also supports serial data transmission, enabling control of devices at the remote location.

It is HDBaseT certified, ensuring interoperability with other HDBaseT compliant devices. The kit requires Cat 5e UTP cabling or better for optimal performance. It supports 7.1 channel audio and includes an RS232 serial port for remote device control.
