Teradek’s impressive new Bolt 4K wireless video transmission system

Posted on Aug 19, 2019

The Bolt 4K is an industry first with its zero-delay 4K HDR transmission capabilities

With new technology, Teradek promises 8x the reliability of previous HD wireless video transmission system models, 1.5x more range, and superior image quality with the new Bolt 4K.

The new system is the first 4K HDR wireless video system providing uncompressed, zero-latency (<1ms) transmission. Additionally, the Bolt 4K allows any model range to transmit and receive from the other (i.e. a Bolt 4K 750 is compatible with a Bolt 4K 1500).

Bolt 4K transmits 10-bit, 4:2:2 HDR video at a range of up to 1,500 feet line-of-sight over the unlicensed 5GHz band, and can multicast to 6 receivers simultaneously. For HDR workflows, Bolt 4K supports the HDR-10, PQ, and HLG standards and can transport extended camera metadata, timecode, and record triggers over the wireless link.

Like Teradek’s existing Bolt devices, Bolt 4K offers AES-256 encryption and RSA 1024 key pairing. Combined, these two technologies ensure nobody can decrypt a user’s wireless feed or connect another receiver to your system without explicit authorization.

To further simplify use, Teradek launched a free iOS app to manage and monitor the Bolt 4K in real-time. Connecting via Bluetooth allows for control over transmitter/receiver pairing, wireless channel selection, and the application of 3D LUTs. The app also offers a real-time quality & range analyser to determine the best transmission distance for a given area as well as a 5GHz spectrum analyser to detect congestion on specific channels.

Teradek’s Bolt 4K is shipping now, priced at $5,490 and $8,990 for the Bolt 4K 750 and Bolt 4k 1500 respectively.
