Take a Closer Look
No Flickering, No Black Screen
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.
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.
HDMI & SDI IN/OUT + SDI LOOPOUT
The Cosmo C1 allows HDMI & SDI connections on both the TX and RX, plus an SDI LOOPOUT interface on the TX. Your solution search ends here because it works with any mainstream camera, monitor, or switcher.
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!
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.
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.
Receiver DC Power Input Port
6-16V
