The Hollyland COSMO C1 Wireless SDI/HDMI Video Transmission System utilises cutting-edge coding and decoding technology, as well as 5G wireless transmission technology, to achieve remarkably low latency in wireless video communication. Its impressive range of over 300m is only possible with a clear line of sight between the transmitter and its single receiver. The L-series battery plate equipping both transmitter and receiver, along with USB Type-C and DC power inputs, provides multiple power options.

Adaptive Frequency Hopping

Improve the reliability, signal strength, and anti-interference capabilities of your production with HEVO, a cutting-edge transmission technology utilizing adaptive frequency hopping (AFH). Say farewell to flickering, pauses, and black screens.

Seamless Channel Switch — You'll Never See It

The HEVO system achieves synchronous frequency hopping in a mere 0.001s at both the receiving and transmitting ends, ensuring seamless picture integrity during frequency switches. Whether in auto or manual switch mode, you can enjoy uninterrupted live streaming and production monitoring without any black screens.

All You Need Is a USB-C Cable

The Cosmo C1 incorporates HEVO, embedding UVC technology for streamlined operation. With just one USB-C cable, it seamlessly transmits 1080p60 HD videos to your computer, allowing for direct live streaming without the need for a video capture device or additional settings. The process is simple and straightforward, requiring no additional effort from the user.

Note: The embedded UVC is only for progressive (p) scan signals.

A Silver Bullet For Focus Puller

Utilizing Hollyland's self-developed protocol, HEVO increases coding efficiency by 30% through the use of H.265 (HEVC). The Cosmo C1's built-in acceleration module achieves an incredibly low latency of 0.04s, maintaining high-quality image output and minimal transmission delay within a 1,000ft (300m) line of sight range.

HDMI & SDI IN/OUT + SDI LOOPOUT

The Cosmo C1 enables both HDMI and SDI connections on both the TX and RX, as well as an SDI LOOPOUT interface on the TX. With compatibility for a wide range of cameras, monitors, and switchers, this device is a comprehensive solution for all your video transmission needs.

Patented Ball Catch Design

The innovative ball catch design on the backplane securely holds the NP-F battery in position, providing a reliable power source.

A Good Routine to “Save Your Work”

The inclusion of a low-battery indicator on the device prevents last-minute emergencies, as the red LED will provide a warning beforehand of a depleted battery.

Built to Match & Easy to Mount

Introducing the COSMO C1 Wireless SDI/HDMI Video Transmission System, designed with more mounting options for convenient and balanced setup on cameras and stabilizers. With a cold shoe design and a 1/4"-20 threaded hole, easily attach the device to any tripod for on-the-go filming. Expertly crafted for seamless and efficient video transmission.

Three Power Supply Options

Three different power supply options are offered to accommodate various shooting scenarios. For indoor shooting conditions, a DC power supply is recommended. For greater mobility and convenience, NP-F batteries and USB-C chargers can be used, making it perfect for run-and-gun tasks.
