Hollyland Cosmo C2 Wireless Video Transmission System 2 Transmitters/1 Receiver Kit

Hollyland Cosmo C2 Wireless Video Transmission System 2 Transmitters/1 Receiver Kit is designed for production crews that need a multi-source wireless video workflow with two transmitters and one receiver. Based on the source images, the kit includes 2 Cosmo C2 wireless video transmitters, 1 Cosmo C2 wireless video receiver, blade antennas, a 12V/2A DC power adapter, USB-C OTG adapter, expansion accessories, cold shoes, user manual, warranty card, and packing list card.

From a broadcast engineering standpoint, this setup is useful when more than one camera or source needs to be sent wirelessly into a shared receiving point. Each 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 gives production teams more flexibility for video assist, director monitoring, and multi-camera event work.

Highlights

• 2-transmitter / 1-receiver wireless video kit for Cosmo C2 workflows
• HDMI and SDI input support on each transmitter for flexible camera connection
• 3G-SDI loopout keeps local camera-side routing available
• Dual HDMI and dual SDI outputs on the receiver for monitoring and routing
• 5.15–5.85GHz operation with 40MHz bandwidth for wireless production video

Why It Helps

For multi-camera production, the main challenge is keeping video routing clean without adding unnecessary cable across the set or venue. This Cosmo C2 kit gives crews two transmitters for camera-side deployment and one receiver with multiple outputs for monitoring, video assist, or production review.

The SDI loopout on each transmitter is especially useful in real production builds. It allows a local SDI feed to continue near the camera while the wireless path sends video back to the receiver. On the receiver side, dual HDMI and dual SDI outputs help support multiple displays or downstream video paths without immediately adding a separate distribution device.

System Characteristics

• Multi-source wireless workflow supports two transmitter points and one receiving station
• HDMI and SDI flexibility fits mixed camera, monitor, and production environments
• SDI loopout path keeps local routing available at each transmitter
• Multiple receiver outputs support cleaner monitor and video assist distribution
• Included antennas and accessories support setup out of the box
