OVERVIEW

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 butter-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.

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 flickering, screen pauses, and black screens throughout the production.

Channel Switching, You'll Never Feel It

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.

All You Need is a USB-C Cable

With HEVO, UVC is embedded in COSMO C1. It simply takes one USB-C cable to pass 1080p60 HD video to your computer for direct live streaming. No video capture device needed, no additional settings. It just works!

A Silver Bullet for Focus Puller

HEVO, based on Hollyland's self-developed protocol, improves coding efficiency by 30% with H.265 (HEVC). The acceleration module embedded in COSMO C1 achieves an ultra-low latency as low as 40ms. There is no compromise on image output and transmission latency within the 1,000ft LOS range.

HDMI&SDI In/Out + SDI Loopout

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.

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.

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.

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. This is ideal for balancing the weight for your setup on both camera and stabilizers, while the 1/4"-20 threaded hole can mount the unit on any tripod.

Three Power Supply Options

Three power supply options to support shooting in different environments. DC power supply is more suitable for use in an indoor shoot, while the L-Series battery and USB-C port make the unit portable for your run and gun shoots.
