With years of dedicated R&D experience, Hollyland is committed to providing the best quality wireless audio and video solutions, redefining the way people create.

Introducing the Hollyland Cosmo C1, a wireless HDMI and SDI transmitter-receiver set that offers a new standard for real-time video monitoring. Powered by Hollyland's HEVO wireless transmission technology, the Cosmo C1 delivers a line-of-sight range of up to 1,000 feet with a latency as low as 40ms.

One of the standout features of the Cosmo C1 is its seamless channel switching. Utilizing Adaptive Frequency Hopping (AFH), the device can complete each synchronous frequency hop in just 0.001 seconds, ensuring picture integrity and eliminating the risk of black screens during live streaming and production monitoring, regardless of whether the mode is manual or automatic.

The Cosmo C1 boasts a wide range of device compatibility, with both HDMI and SDI input options, as well as SDI loopout in the transmitter and HDMI, SDI, and UVC (USB Video Class) output in the receiver. This versatility allows users to work with a variety of cameras, monitors, and live streaming setups.

Designed with convenience in mind, the Cosmo C1 offers multiple mounting options, including a patented ball catch mechanism to securely hold NP-F series batteries, as well as cold shoe and 1/4"-20 threaded mounts for both the transmitter and receiver. The auto fan mode intelligently adjusts the fan speed based on the device's temperature, ensuring quiet operation.

To test the latency, users can simply use a computer and a mobile phone to capture the time displayed on both the computer and the monitor, before and after connecting the Cosmo C1. The difference in time will indicate the transmission delay.

The Cosmo C1 package includes a transmitter, receiver, hard plastic case, antennas, hot/cold shoe, and various accessories, making it a complete solution for wireless video transmission. Compared to other Hollyland video transmission systems, the Cosmo C1 stands out with its industry-first UVC integration, 1,000-foot range, and 40ms minimum latency.

Whether you're a professional videographer, live streamer, or content creator, the Hollyland Cosmo C1 offers a reliable and versatile wireless video transmission solution, redefining the way you capture and share your work.
