RECOMMENDED ACCESSORIES
Hollyland Cosmo C1 Overview
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 up to 1000' to a single receiver, allowing flexible video monitoring and distribution for your studio or field production. This kit consists of a transmitter and a receiver that communicate over the 5.1 to 5.9 GHz wireless frequency range.
Solid, Secure Wireless Transmission
The Cosmo C1 can transmit video up to 1000' line-of-sight with a low 40 ms 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. 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.
Live Video Input/Output
- 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.
Input/Output Transmission Formats
Versatile Power and Form Factor
- Both compact units also feature a bright, easy-to-read OLED display showing status and configuration
- Each unit can be powered via an L-series battery plate, DC input, or with an optional USB power supply via the USB Type-C port
- Four standard antennas and two mushroom antennas are supplied for the receiver and transmitter
- Each unit is easy to mount just about anywhere using its 1/4"-20 threads and included shoe mount adapter
Multiple Mounting Methods
You can mount the transmitter and receiver using the cold shoe on the front panel for horizontal mounting, and you can utilize the 1/4"-20 thread to mount the unit on a tripod or cage.
Auto Fan Mode
The COSMO C1 can adjust the fan speed according to the device's temperature, and it is so quiet it is hardly felt or heard.
Low-Battery Indicator
Both the Cosmo C1 transmitter and receiver have a low-battery indicator above the LCD on the side. Once the indicator shows red, the device will run out of battery in 20 minutes, so you have plenty of time to replace the battery or connect to a power source.
