Unveiled today at NAB 2019, Teradek's Bolt 4K is the first 4K HDR wireless video system providing uncompressed, zero-latency transmission. It's also interoperable, allowing any model range to transmit and receive from the other.

Bolt 4K can not only transmit 10-bit, 4:2:2 HDR video at up to 1,500 feet line-of-sight over the unlicensed 5GHz band but can also multicast to 6 receivers at the same time. It comes with HDR-10, PQ, and HLG support and can transport camera metadata, timecode, and record triggers over the wireless link. Another interesting feature include AES-256 encryption and RSA 1024 pairing, meaning that your feed and system is well protected.

Teradek has also launched its free iOS app that allows users to manage and monitor the Bolt 4K in real-time, including transmitter/receiver pairing, wireless channel selection, and application of 3D LUTs. Users can also check the app to determine the best transmission distance with the quality and range analyzer, as well as the popular 5GHz spectrum analyzer.
