Teradek has announced the new Bolt 4K which can transmit a 4K HDR image with zero-latency (<1ms). The new Bolt 4K line is interoperable with each other so you don’t need matching transmitter/receiver models (i.e. a Bolt 4K 750 is compatible with a Bolt 4K 1500).
Teradek claims that the Bolt 4K offers 8x the reliability of previous HD models, 1.5x more range and superior image quality.
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
The Bolt 4K transmitter units feature dual 12G SDI and HDMI 2.0 inputs, while the receivers offer dual 12G SDI and a single HDMI 2.0 output.
Extended camera metadata, timecode, and record triggers for industry standard cameras from ARRI, RED, Sony, Canon, and more are all sent across wirelessly.
Mounting the transmitter can be done via the ARRI ⅜-16” Pin-Lock mounting point for camera arms, or with an optional camera-back mount with Gold/V-Mount pass-through power.
The new Bolt 4K units feature a built-in OLED screen for fast access to signal and picture status. The new Bolt for iOS app makes it easier than ever to pair units together and provides additional information about signal status, LUTs, range information and more.
The new Bolt 4K system uses AES-256 encryption with RSA 1024 key pairing for a robust and secure wireless feed. This makes it extremely difficult to decrypt the wireless feed or connect to a transmitter without explicit authorization. All Bolt 4K systems can multicast up to 6 receivers.
