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.

Both units feature a bright, easy-to-read OLED display showing status and configuration and 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
Each unit is easy to mount just about anywhere using its 1/4″-20 threads and included shoe mount adapter

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.
Both units 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.
