Hollyland Cosmo C2 Wireless Video Transmission System Transmitter/Receiver Kit

Hollyland Cosmo C2 Wireless Video Transmission System Transmitter/Receiver Kit is designed for production crews that need a dedicated wireless video link between a camera or source and one or more monitoring destinations. Based on the source images, the kit includes a Cosmo C2 wireless video transmitter, a Cosmo C2 wireless video receiver, blade antennas, power adapter, USB-C OTG adapter, expansion accessory, cold shoe, user manual, warranty card, and packing list card.

From a broadcast engineering standpoint, this kit gives crews a clean transmit-and-receive workflow. The transmitter supports HDMI 1.4b input, 3G-SDI input, and 3G-SDI loopout, while the receiver provides 2 x HDMI 1.4b outputs and 2 x 3G-SDI outputs. That is useful when a wireless camera feed needs to reach multiple monitors, video assist stations, or production routing points.

Highlights

• Wireless video transmitter and receiver kit for Cosmo C2 production workflows
• HDMI and SDI input support on the transmitter for flexible source connection
• SDI loopout on the transmitter keeps a local hardwired video path available
• Dual HDMI and dual SDI outputs on the receiver for multi-monitor routing
• 5.15–5.85GHz operation with 40MHz bandwidth for wireless production video

Why It Helps

For production work, a wireless video system needs to be simple to place, easy to power, and flexible enough to feed the right destinations. The Cosmo C2 kit gives crews a transmitter for the camera or source side and a receiver with multiple HDMI and SDI outputs for monitoring or routing on the other end.

The transmitter-side SDI loopout is a useful field detail. It lets a local SDI feed continue near the camera while the wireless link sends video to the receiver. On the receive side, having two HDMI outputs and two SDI outputs helps support director monitors, video assist, production carts, or client viewing without immediately adding extra distribution hardware.

System Characteristics

• End-to-end wireless video workflow includes both transmitter and receiver
• HDMI and SDI flexibility supports mixed camera, monitor, and production environments
• SDI loopout path keeps local camera-side routing available
• Multiple receiver outputs support cleaner monitor and video assist distribution
• Included antennas and accessories support setup out of the box
