Hollyland Cosmo C1 Wireless Video SDI/HDMI Transmission System (5GHz)

New standard for real-time video monitoring

The Hollyland Cosmo C1 Wireless SDI/HDMI Transmission System is using the latest coding, decoding technology, and 5G wireless transmission technology. Industry-first to integrate UVC (USB Video Capture) interface, COSMO C1 offers a whole simplified solution to stream and cloud-share your video works. It can achieve ultra-low latency wireless video transmission over a range of 350 meters with a clean line of sight (LOS) when the transmitter is connected to a C1 receiver. Both the transmitter and receiver come with an L-series battery plate and can power up via USB Type-C port and DC power input. 

High-Definition Video Transmission
The Cosmo C1 SDI/HDMI Wireless Video Transmission System from Hollyland allows you to wirelessly transmit high-resolution video up to 1080p60 over long distances, allowing flexible video monitoring and distribution for your studio or field production. This kit consists of a transmitter and a receiver.

The Cosmo C1 can smoothly transmit video up to 350m (1000ft) line-of-sight with a low 0.04s latency using the HEVC/H.265 codec. The system operates on the 5 GHz frequency band and uses AES-128 encryption to prevent video leakage, offering superior anti-interference capability. It also supports smart channel selection, allowing the system to choose the cleanest channel for transmission, as well as HEVO, an adaptive frequency hopping technology, for seamless retransmission without losing a frame.

The transmitter offers one HDMI input, one SDI input, and one SDI loop-through output, and the receiver offers two SDI outputs and one HDMI output.
The receiver can also be used for live streaming via its USB Type-C output, supporting UVC applications on your Internet-connected computer.
