Hollyland Cosmo C1 SDI/HDMI Wireless Video Transmission System

TX/RX Kit for 1080p60 up to 1000' LOS — AES-128 Encryption & ~40 ms Latency

Overview

The Hollyland Cosmo C1 SDI/HDMI Wireless Video Transmission System lets you transmit high-definition video up to 1080p60 over long distances up to 1000' (304.8 m) line-of-sight to a single receiver, enabling flexible monitoring and distribution for studio or field production.

Operating across the 5.1 to 5.9 GHz wireless range, the system leverages HEVC/H.265 for efficient transmission and delivers a low ~40 ms latency. To keep your feed secure, it supports AES-128 encryption to help prevent signal leakage.

The transmitter provides HDMI and SDI inputs plus an SDI loop-through, while the receiver offers HDMI out and dual SDI outputs. Both units feature bright OLED status displays and flexible power options via Sony L-series battery plates, DC, or USB-C, along with multiple mounting methods using a cold shoe and 1/4"-20 threads.
