Hollyland Cosmo C1 Wireless SDI/HDMI Transmission System with Weatherproof Hard Case

Hollyland Cosmo C1 Wireless SDI/HDMI Transmission System

This new member of the Cosmo series, the Hollyland Cosmo C1 Wireless SDI/HDMI Transmission System has been transformed by Hollyland's HEVO wireless transmission technology. It offers a new standard for real-time video monitoring up to 1,000 feet of line-of-sight. Boosted signal strength and superior anti-interference capability in the 5.1GHz to 5.8GHz frequency spectrum guarantee buttery smooth video transmission in complex environments. Industry-first to integrate UVC (USB Video Capture) interface, Cosmo C1 offers a whole simplified solution to stream and cloud-share your video works. It's the new go-to choice to step up your content production teams.

No Flickering, No Black Screen

HEVO, a solution embedded with adaptive frequency hopping (AFH) and seamless retransmitting technology, brings exceptional reliability, boosted signal strength, and superior anti-interference performance. You can now say goodbye to screen flickerings, screen pauses, and black screens throughout the production. With this level of anti-interference performance, it still allows 4 sets of video transmission systems to work at one location without compromising their smooth video delivery.

Channel Switching, You'll Never Feel It

EVO completes each synchronous frequency hopping in 0.001s at both receiving and transmitting ends that ensures picture integrity at the instant of frequency switching. Whether in manual or auto-switching mode, your live streaming and production monitoring will no longer suffer black screens. Cosmo C1 has already completed thousands of channel switching when on-location directors or remote clients are monitoring the production in environments with complex wireless signals.

HEVO for Ultra-Low Latency

HEVO, based on Hollyland's self-developed protocol, improves coding efficiency by 30 percent. The acceleration module embedded in Cosmo C1 achieves an ultra-low latency of as low as 40ms. There is no compromise on image output and transmission latency within the 1,000-feet LOS range. Designed for precise follow focus and high image clarity, Cosmo C1 is a silver bullet for videographers and focus pullers. Say Hi to a whole new level of the smooth viewing experience.

HDMI and SDI In/Out + SDI Loopout

Cosmo C1 allows HDMI and SDI connections on both the TX and RX unit, plus an SDI loop-out on the TX. It can work with any mainstream camera, monitor, or switcher you happen.

Vertical and Horizontal Mount Design

More mounting methods are available on both the transmitter and receiver. The cold shoe mounting design at the front allows fixing and laying the unit horizontally, ideal for evening out the weight for balancing setup on camera and stabilizers, while the 1/4-inch-20 threaded hole erects the unit on any tripods.

Three Power Supply Options

Three power supply options to escort in different shooting scenes. DC power supply is more suitable for use in an indoor project, while the L-series battery and USB-C port make the unit portable for your run and gun missions.
