Holly Who??? Perfect Client Monitor

The delay is very minimal and the connection has been superb?. Highly recommend it as a client monitor? the feed actually looks better than a teradek 750 bolt? only downside is the little bit of lag! Unless you are doing some very delicate focus pulling this item is so worth it! FYI (you could probably get away with pulling focus depending on the shot)

Holly Who??? Perfect Client Monitor

Before you delve into the world of professional video production, consider the Cosmo C1 SDI/HDMI Wireless Video Transmission System, a revolutionary addition to the COSMO series. Powered by Hollyland's advanced HEVO wireless transmission technology, this innovative system sets a new benchmark for real-time video monitoring, offering an impressive range of up to 1,000ft line-of-sight.

The Cosmo C1 boasts enhanced signal strength and superior anti-interference capabilities within the 5.1 GHz-5.8GHz frequency spectrum, ensuring smooth, high-quality video transmission even in challenging environments. As an industry pioneer, it is the first to integrate a UVC (USB Video Class) interface, offering a streamlined solution for video streaming and cloud-sharing.

The Cosmo C1 is equipped with the groundbreaking HEVO solution, which features adaptive frequency hopping (AFH) and seamless retransmitting technology. This guarantees exceptional reliability and superior anti-interference performance, eliminating screen flickerings, pauses, and black screens during production.

The system's ultra-low latency of 40ms, coupled with seamless channel switching, ensures picture integrity and uninterrupted live streaming. The embedded UVC allows for direct live streaming of 1080P60 HD video to your computer via a single USB-C cable, eliminating the need for additional video capture devices or settings.

The Cosmo C1 is designed with versatility in mind, offering HDMI & SDI connections on both the transmitter and receiver units, plus an SDI loopout on the transmitter. This ensures compatibility with any mainstream camera, monitor, or switcher.

The system's robust design includes a patented ball catch on the backplane to securely hold NP-F series batteries, ensuring a steady power supply. A low-battery indicator provides a 20-minute warning to prevent last-minute panic.

With multiple mounting methods available on both the transmitter and receiver, the Cosmo C1 is easy to install and balance on cameras and stabilizers. It also offers three power supply options to cater to different shooting scenes, making it an ideal tool for professional filmmaking, live streaming of micro-events, commercial shooting, and more.

  • As low as 40ms Transmission Latency
  • 1000' Wireless Transmission Range (LOS)
  • Supports Smart Channel Selection
  • Transmitter Supports SDI Input, HDMI Input, and SDI Loopout
