Overview
ULR1 | Video Transmission System with SDI and HDMI up to 1200m Using WHDI Technology
The DwarfConnection DC-LINK-ULR1 stands as the premier model in the 2nd generation of video transmission systems from DwarfConnection. With a direct line-of-sight range of up to 1200 meters, it ranks among the most powerful WHDI systems available. Like all 2nd generation systems, the ULR1 is backward compatible and can be integrated and expanded with the entire DFS-free DC-LINK product range.
To ensure optimal channel selection, the ULR1 features a frequency scanner and an antenna function monitor, known as DC-SCAN, which can output through the receiver’s HDMI port. Note that the wireless video transmission and frequency monitoring functions cannot be used simultaneously.
DC-LINK systems achieve exceptional stability by intentionally forgoing DFS (Dynamic Frequency Selection), which confines their use to specified indoor channels.
The fan settings on both transmitters and receivers can be adjusted or turned off. For live area use, the on-screen display (OSD) can also be disabled.
An OLED display on both the transmitter and receiver shows the selected channel, temperature, and battery charge level. Five large LEDs on the receiver indicate reception quality, even in bright environments.
The ULR1 supports the transmission of time code and start/stop signals. It also facilitates quick switching between the camera image and recorded footage, making it one of the most versatile video transmission systems available.
