ST121R VGA over Cat5 video extender receiver is specifically designed for use as the receiver unit to the ST1214T 4 port, and ST1218T 8 port VGA over Cat5 UTP extender transmitter units, allowing to split and extend a single VGA source to up to four remote displays. From the transmitter device, the VGA video signal is sent over standard 4 pair Category 5 or better UTP cable to remote monitors, each connected to an ST121R Cat 5 VGA receiver supporting distances of up to 150m (500ft). A cost-effective video extension solution, this receiver is ideal for a wide range of environments including airports, bus depots, retail, or any large buildings where VGA video needs to be extended to long connection distances.
