Next-Level Wireless Video Transmission for Multi-Camera Productions
Seamless Multi-Camera Wireless Workflow
The Hollyland Cosmo C2 2TX & 1RX Kit is designed to revolutionize multi-camera live streaming, electronic field production (EFP), and professional broadcasting. With its dual-transmitter to single-receiver configuration, this system eliminates cabling clutter, synchronization delays, and spatial constraints commonly faced in traditional setups.
By allowing two transmitters to send video signals to a single receiver, the Cosmo C2 ensures flawless synchronization between camera feeds, reducing setup time and increasing efficiency for live event coverage, filmmaking, and commercial productions.
Unrivaled Wireless Transmission Performance
- Superior Range & Stability: The Cosmo C2 offers a wireless transmission range of up to 1,000 meters (line-of-sight) and a back-to-back transmission distance of over 300 meters.
- Ultra-Low Latency: With a latency as low as 33 milliseconds, the system outperforms conventional 60ms setups, ensuring precise audio-video synchronization—critical for LED screens and live productions.
- Advanced HEVO 2.0 Technology: This system automatically detects interference and seamlessly switches to a clean channel, eliminating video stuttering, dropped frames, or signal loss in high-traffic RF environments.
Professional-Grade Video & Audio Capabilities
- Full HD Transmission: Supports 1080p60, 1080p50, 1080p30, and other frame rates with zero image degradation.
- Frame Rate Compensation Algorithm: Smooths out low frame rate inputs to 60P, ensuring fluid motion in fast-paced environments.
- Lossless Audio Transmission: Delivers embedded 2-channel 48kHz 24-bit audio, preserving high-fidelity sound quality for broadcast and post-production workflows.
Versatile Connectivity & Seamless Integration
- Dual HDMI & SDI Support: The system accommodates both HDMI and SDI connections, making it compatible with a wide range of professional cameras, monitors, and switchers.
- Comprehensive I/O Ports:
- Transmitter (TX): HDMI Input, SDI Input, SDI Loopout
- Receiver (RX): HDMI Output, Dual SDI Outputs
- Plug-and-Play Streaming:
