Hollyland COSMO C1 Wireless HDMI/3G-SDI

300m Wireless SDI/HDMI Transmission System

This new member to the COSMO series, transformed by Hollyland's HEVO wireless transmission technology, offers a new standard for real-time video monitoring up to 1,000ft line-of-sight. Boosted signal strength and superior anti-interference capability in the 5.1GHz-5.8GHz frequency spectrum guarantee buttery-smooth video transmission in complex environments. Industry-first to integrate UVC (USB Video Class) 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 to the next level.

No Flickering, No Black Screen
HEVO, The Game Changer
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.

• Real-time video transmission up to 1000ft LOS
• Superior anti-interference in 5.1GHz-5.8GHz frequency spectrum

**Channel Switching, You'll Never Feel It ** HEVO, Fast, Stable, and Smart
HEVO 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 on 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.

All You Need Is an USB-C Cable
Embeded Video Capture Like None Other
With HEVO, UVC is embedded in COSMO C1. It simply takes one USB-C to pass 1080P60 HD video to your computer for direct live streaming. No video capture device needed, no additional settings. It just works!
NOTE: Embedded UVC only for "P" / Progressive scan signals mode.

A Silver Bullet for Focus Puller
HEVO for Ultra Low Latency
HEVO, based on Hollyland's self-developedprotocol, improves coding efficiency by 30% with H.265 (HEVC). The acceleration module embedded in COSMOC 1 achieves an ultra-low latency as low as 40ms. There is no compromise on image output and transmission latency within the 1000ft 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 smooth viewing experience.

HDMI&SDI In/Out + SDI Loopout
A Wide Range Of Device Compatibility
COSMO C1 allows HDMI & SDI connections on both the TX and RX unit, plus an SDI loopout on the TX. It can work with any mainstream camera, monitor, or switcher you happen to work on. Your deal search ends here, period.

Battery Low Indicator
A Good Routine as "Save Your Work"
The low battery indicator in red is here to remind you 20 minutes in advance of a dying battery. No more last-minute panic.

Vertical & Horizontal Mount Design
Built to Match, Easy to Mount
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"-20 threaded hole erects the unit on any tripods.

Three Power Supply Options
Power That's Nonstoppable
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.

Patented Ball Catch Design
Locked To The Max
The patented ball catch design on the backplane can hold the NP-F series batteries firmly in place. Be rest assured of a steady power supply.
