The Teradek Bolt 1000 XT 3G-SDI/HDMI Wireless Transmitter and Receiver Set includes one transmitter and one receiver. This set enables you to immediately start transmitting up to 1080p60 video from either an SDI or HDMI source. The zero-latency transmitter/receiver pair features 1000' line-of-sight transmission distance when used together. You can send and receive visually lossless 3G video signals from a Bolt 1000 transmitter with zero latency. The transmitter features cross conversion, so you take an SDI signal in and loop out either an SDI or HDMI signal to your on-camera monitor.
