Hollyland Pyro Ultra 4K HDMI/SDI Wireless Video Transmitter
Enhance your production with up to 4K60 wireless video transmission by utilizing the versatile Pyro Ultra 4K HDMI/SDI Wireless Video Transmitter from Hollyland. This transmitter is equipped with both an HDMI and an SDI input port, allowing for line-of-sight transmission distances of up to 4900 feet. The TWiFi transmission technology establishes a composite link with automatic frequency hopping, ensuring exceptional clarity and a low latency of 20 milliseconds. Furthermore, additional operating modes provide increased functionality tailored to the specific requirements of your production. The Pyro Ultra is also backward compatible with the entire Pyro family, ensuring seamless integration with your existing workflows.
- The Pro Ultra ecosystem can be expanded to include unlimited receivers getting footage from a single transmitter unit, all while continuing to deliver stable wireless signals.
- TWiFi is a new proprietary codec developed by Hollyland that combines 2.4 and 5 GHz wireless signals to establish a secure communication link. This system is capable of maintaining line-of-sight transmission over distances of up to 4900 feet. Furthermore, it employs automatic frequency hopping to mitigate signal interference in densely populated network settings. Additionally, Dynamic Frequency Selection expands access to the wireless spectrum in regulated areas, providing greater flexibility.
- When enabled, Broadcast mode provides real-time signal monitoring to numerous receiver units from a distance of 2300 feet. When turned off, the conventional configuration accommodates up to six monitoring screens—comprising four receivers and two mobile applications—extending up to 4900 feet.
- When attempting to execute accurate focus pulls, Focus mode ensures minimal latency to provide a responsive monitoring environment. The latency fluctuates based on the output resolution of your footage, registering at 20 ms for 1080p30, 40 ms for 1080p60, and 45 ms for 4K60.
- The Pyro Ultra offers both UVC and RTMP streaming capabilities. Its plug-and-play connectivity, along with versatile platform compatibility, renders the receiver perfect for live production and remote collaboration.
- The system automatically freezes the last frame on screen when an unexpected cut occurs to give production crews time to recover. You can even set up a custom image as a default display to maintain visual consistency.
- The transmitter unit features a DC power input to connect a separately available power supply. An NP-F battery plate allows you to integrate an L-series battery for longer shoot times on set.
