HEVO, the Game Changer
No Flickering, No Black Screen
AFH
Adaptive Frequency Hopping
HEVO, a seamless transmission technology empowered by adaptive frequency hopping (AFH), brings exceptional reliability, boosted signal strength, and superior anti-interference performance. Say goodbye to flickerings, pauses, and black screens throughout the production.
HEVO
HEVO — Fast, Stable, and Smart
Seamless Channel Switch — You'll Never See It
HEVO completes synchronous frequency hopping in 0.001s at both the receiving and transmitting ends, ensuring picture integrity at the very instant of the frequency switch. In either the auto or the manual switch mode, your live streaming and production monitoring will no longer experience black screens.
HEVO with Embedded UVC
All You Need Is a USB-C Cable
With HEVO, UVC is embedded in the Cosmo C1. It simply uses one USB-C cable to transmit 1080p60 HD
videos
to your computer for direct live streaming. No need for a video capture device or additional
settings.
It just works!
Note: The embedded UVC is only for progressive (p) scan signals.
HEVO for Zero-Hit Latency
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 the Cosmo C1 achieves an ultra-low 0.04s latency. There is virtually no compromise in image output and transmission latency within the 1,000ft (300m) LOS range.

Patented Ball Catch Design
The patented ball catch design on the backplane can hold the NP-F battery firmly in place. Be rest assured of a secured power supply.
Low-Battery Indicator
A Good Routine to “Save Your Work”
The low-battery indicator helps eliminate another last-minute panic, because the red LED will remind you in advance of a dying battery.
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 you to fix and lay the device horizontally, ideal for achieving a balanced setup on cameras and stabilizers. Its 1/4″-20 threaded hole helps mount the device on any tripod.
Unfailing Power
Three Power Supply Options
Three power supply options are available for different shooting scenarios. DC power supply is ideal for indoor shooting conditions, and the use of NP-F batteries and USB-C chargers facilitates mobility and supports your run-and-gun tasks.
Cosmo C1 Applications
