The kit includes a wireless transmitter and receiver that feature bright OLED displays and can wirelessly receive up to 4K30 video with 10-bit 4:2:2 HDR support. The transmitter inputs up to 4K video over HDMI or up to 1080p60 video via 3G-SDI, and the receiver outputs video via HDMI and 3G-SDI.

The transmitter sends up to 4K30 video to the Bolt 4K LT receiver, and it can also simultaneously transmit to up to six receivers. The system features improved metadata, range, and compatibility over its predecessors. The built-in AES-256 encryption with RSA 1024 key pairing protects your video from prying eyes, while noise rejection keeps your video clean no matter how many devices are using the wireless spectrum. The Bolt LT system also supports the transmission of timecode and start/stop triggers from the camera.

The Bolt 4K series units are all cross-compatible, so you can transmit to different Bolt 4K series receiver models. The system also supports an iOS app that easily connects via Bluetooth, which provides a spectrum analyzer, channel selection tools, and remote configuration. There are 1/4"-20 and M3 mounting threads to mount your transmitter and receiver on a variety of cameras, cages, or rigs.
