The UV1-S converts a VGA signal into a Cat5 and sends this Cat5 signal to one of the following devices: (UV1-R and UV1-R-WP). The UV1-S is supplied phantom power via the Cat5 from the receiving unit or from a local power supply. The UV1-S can drive Cat5 cables of lengths of up to 500 feet (150 meters) with little to no degradation of video quality.
